Tesla batteries lose just 1% capacity each year

Tesla battery life loss

A real-world study of Teslas has revealed how much battery capacity the electric cars lose over time. And the good news is the losses are marginal: around one percent each year.

Just as an internal combustion car loses horsepower over time, electric cars have less battery capacity as they age. Think of it as your car’s fuel tank getting marginally smaller every year.

The Tesla research was carried out by Plug In America and analysed by NimbleFins. Five hundred Tesla Model S owners submitted data on the usage of their cars. These included when it was manufactured, bought, the battery size, the quoted range (when new) and the mileage the car has covered.

Tesla battery life loss

A general takeaway is that the more mileage an electric car has, the more battery capacity it will have lost. Remember, more mileage means more charging. The car with the highest mileage in the study, a Model S P85 with 232,442 miles, was capable of charging to a 220-mile capability. That’s 83 percent of its original 265-mile range when new. Up to around 150,000 miles, the cars seem to retain 90 percent of their charge capacity.

‘It’s interesting to see that a car with unusually high mileage for the age (over 143,000 miles for a car less than 5 years old) has more significant battery deterioration than a typical car of the same age,’ said the report.

‘This shows that mileage is also a considerable factor in how quickly a battery deteriorates—this makes sense, as more miles driven means more charge cycles, and it’s mostly the charge cycles that reduce a battery’s usable capacity.’

The average mileage in the UK is 7,600 a year. On that basis, an original high-end Model S would take 30 years to reach that unusually high mileage of 230,000 miles, or 20 years to reach 150,000 miles. With the assumption, of course, that time doesn’t play into that degradation.

It would be very interesting to test a seven-year-old Model S that hasn’t covered any miles.

Tesla battery life loss

Overall, the results seem to show that battery tech used even in the very first Teslas is relatively robust. Many worry about the longevity of electric cars, but if their performance at what is considered end-of-life mileage (and even beyond) is as suggested, buyers can expect a decent life.

And as battery technology progresses, so too may the already impressive longevity.

Elon Musk spotted driving Cybertruck in LA

Elon Musk Tesla Cybertruck LA

In the weeks since its reveal, the furore around Tesla’s Cybertruck hasn’t relented. Some even speculated that this otherworldly all-electric answer to Ford’s F150 wasn’t actually real.

Well, speculate no longer. It’s been spotted out in the wild, with its windows fully intact, mingling with traffic in Los Angeles and heading out to dinner.

Elon Musk Tesla Cybertruck LA

It somehow looks even crazier out in traffic surrounded by normal cars. Jack Phan, the Twitter user who posted the snap, speculated about whether it was Mr Musk himself behind the wheel.

We can’t imagine it being anyone else and he can’t have been worried about being spotted. The Tesla Cybertruck could make a Lamborghini Countach driving with its doors up blend into the background.

In a follow-up post, the truck is pictured at Nobu Sushi stealing the show in a car park populated by McLarens and Range Rovers. A clear shot at the front shows Musk and friends six-up in the truck.

With all lights and eyes on the Cybertruck, its harsh sharp edges are almost glowing as they reflect.

Elon Musk Tesla Cybertruck LA

As of 27 November, over 250,000 people had placed an order for a Cybertruck. It remains to be seen how many people actually see it through to delivery. You can place an order with a fully-refundable £100 down payment.

Deliveries of the Cybertruck aren’t expected to begin until 2022, so those with a reservation have plenty of time to consider their purchase. That also gives Tesla and Mr Musk time to have a tug-of-war rematch with Ford and the F150, after he accepted a tongue-in-cheek challenge from a Ford high-up.

Tesla Income Tax Credit Running Out

Time is almost up for U.S. federal income tax credits on new Teslas

Tesla Income Tax Credit Running Out

Those interested in getting federal income tax credit on the purchase of a new Tesla Model 3, Model S, or Model X are fast running out of time.   

That is the message from Tesla itself, which sent subscribers to its newsletter a warning that they have just five weeks to take delivery in order to qualify.

The expiration of the federal tax credit for Tesla is controversial, with the initiative intended to encourage sales of plug-in vehicles.

Tesla Income Tax Credit Running Out

The origins of the federal income tax credits come from the Energy Improvement and Extension Act of 2008, signed into law by George W. Bush. 

Along with allowing the United States government to purchase assets affected by the global financial crisis, it also provided federal income tax credits for electric vehicles. 

Given that U.S. automakers were heavily affected by the recession, incentivising consumers to buy new plug-in electric and hybrid vehicles made sense as an effective short-term measure. 

Providing federal income tax credits of up to $7,500 for each car, the legislation included a ‘phase-out’ that would apply once a manufacturer delivered 200,000 qualifying cars. 

Tesla Income Tax Credit Running Out

Tesla triggered the phase-out limit in July 2018, which saw the maximum tax credit amount reduce to $3,750 for cars delivered between January 1st and June 30th, 2019. Those delivered after June 30th, but before December 31st 2019, will receive just $1,875 in credit.

All Tesla cars delivered on or after January 1st 2020 will receive no federal tax credit, although buyers may still qualify for various individual state incentives. 

Some have argued that this effectively penalizes early-adopters of plug-in vehicles, whilst others view this as the limit of legislation enacted more than a decade ago. 

Tesla Income Tax Credit Running Out

General Motors also triggered the phase-out procedure in November 2018, seeing tax credits for qualifying models currently reduced to $1,875. The IRS website notes that GM products will cease to receive any federal credit for cars delivered after March 31st 2020.

At present, all other manufacturers selling plug-in electric vehicles in the United States are still able to see their customers receive federal income tax credits. 

The federal tax credit operates by reducing the actual amount of income tax owed by an individual, rather than a deduction which reduces the amount that income tax is calculated upon. 

Elon Musk says ‘bring it on’ to Cybertruck tug-of-war rematch

Ford v Tesla Elon Musk challenge

Elon Musk has responded to Ford’s request for an ‘apples-to-apples’ truck tug of war. The Tesla CEO said “bring it on”, after the Sundeep Madra, vice president of Ford X at Ford Motor Company, threw down the gauntlet yesterday.

The reason for the rematch? A video of the Cybertruck winning a tug of war with an F-150 pick-up has been criticised for being unfairly tipped in the trapezoidal Tesla’s favour.

The F-150 in question was either a rear-wheel-drive model, or was in rear-wheel-drive mode. In short, with power going to all four wheels, it could have had the advantage.

Not quite the convincing proof that the Cybertruck is “better than an F-150” as Musk claims.

Interestingly, Madra said Tesla should send Ford a Cybertruck with which to perform the new tug-of-war. For all Musk’s retaliatory bravado, we’d be highly surprised if he does that.

It might not be an issue anyway, given that Ford itself has qualified Madra’s challenge as ‘tongue-in-cheek’ in a statement to InsideEVs. Will the rematch happen at all, if it was all Twitter posturing?

It’s not like Ford has much to prove. A few months ago, it released a video of a prototype electric F-150 towing one million pounds (453,592kg) of laden freight train.

Other manufacturers have poked fun at Tesla, too. In response to the Cybertruck’s rocky reveal, BMW showed off its armoured X5, saying it ‘comes with bulletproof windows and offers splinter protection in case it gets hit by a metal ball’.

Of course, that refers to the Cybertruck’s ‘unbreakable’ windows that broke on stage, causing Musk to blurt expletives.

BMW makes dig at Tesla Cybertruck launch

BMW makes subtle dig at Tesla following Cybertruck launch event

BMW makes dig at Tesla Cybertruck launchEven in a week which included the launch of a battery-powered Ford Mustang, the biggest talking point from Los Angeles has been the Tesla Cybertruck.

Revealed with typical Tesla theatrics, the futuristic all-electric pickup truck has generated controversy. This ranges from its looks, to the actual ability of Tesla to even build it.

Yet the shattered glass at the launch event, caused by a metal ball, prompted BMW to subtly remind the world that its vehicles already offer bulletproof windows. 

Tesla’s troubles came when design chief Franz von Holzhausen attempted to demonstrate the strength of the glass in the prototype Cybertruck. With Tesla CEO Elon Musk claiming the windows were “bulletproof to a 9mm handgun”, a metal ball should have been no issue. 

Instead, the side windows of the Cybertruck shattered when von Holzhausen lugged a metal ball at them, causing splinters and shocked faces in equal measure. 

Musk was keen to point out that previous attempts had failed to damage the glass. He added it would be sorted before customers took delivery of production Cybertrucks.

BMW’s tweet about metal balls and splinters was clearly referencing the Tesla event. But also reminding buyers about the impressive abilities of the armoured X5 Protection VR6.

The X5 VR6 has been certified as resistant to firearms and explosives, with its windows one of the key components. It uses multilayered safety glass capable of withstanding attacks by impact weapons – like metal balls – and comes with an internal polycarbonate layer to stop splinters.

BMW does not disclose prices for the X5 VR6, but the X5 M50i that serves as the base for the armoured version begins at £74,620 ($82,150). This makes it considerably more expensive than the anticipated £31,000 ($39,900) Cybertruck.

Although Tesla may have dominated social media with the reveal of the Cybertruck, the event has financial investors worried. Tesla’s share price fell by 6% on Friday after the launch, with Forbes noting that this would wipe $768 million (£599 million) from Elon Musk’s personal wealth alone.

BMW makes dig at Tesla Cybertruck launch

Tesla’s entry-level Model 3 has found success this year, becoming a UK top-10 best-seller earlier this year. Yet the company is also building up a backlog of models to launch, which the Cybertruck only adds to. 

Along with the new pickup for 2021, Tesla is promising to launch the Model Y compact crossover, new Roadster, and its Semi truck during 2020. This pressure to deliver, rather than the Cybertruck launch, may be causing investors to worry. 

For those needing an armoured pickup truck right now, there is always the option to try and persuade BMW to build a VR6 version of the X7 Pick-up concept.

Today’s non-Cybertruck news: Lara Croft, snow sticks and a stuck Skoda

Lara Croft wax model

Where were you when Tesla unveiled the Cybertruck?

It’s not quite the moon landing, the fall of the Berlin Wall or a meal at Pizza Express, but for Tesla fans, it’s another moment in history. A significant date for the memory bank.

Tesla – and more specifically, the Cybertruck – has been trending on Twitter ever since. It’s secured top billing on the BBC homepage, while the Daily Mail has even given it greater prominence than Millie Mackintosh’s ‘bare bump’ and the ‘plunging gown’ of Charli XCX.

When you’re getting more exposure than Charli’s ‘floral tubing around the bosom and asymmetrical hemline’, you know you’ve managed to spin the PR thing to perfection.

Aside from a well-known yeast extract, nothing divides opinion quite like a new Tesla. Everything Elon Musk does appears to usher in an open season for opinions, memes and witty critiques.

This morning, the Tesla Cybertruck was likened to everything from Lara Croft’s ‘enviable assets’ (to use the Mail’s terminology) to a rubber door wedge. Some were witty – a few were even original.

Every day except Wednesday, Motoring Research asks me to write an opinion piece on something topical or newsworthy. I get the day off on Wednesday, presumably because, aside from the bin collection, nothing ever happens on a Wednesday.

As today is Friday, I’m free to write something on the Tesla Cybertruck. But I won’t. Not only has Ethan got there first, but there are literally no opinions left. I’ve shone a torch into the bowels of the opinion-o-generator and there’s nothing there. Zilch. Zero. Nadda.

More news than you can shake a stick at

Toyota Corolla

Instead, allow me to take you on a tour of some of the stories you might have missed. While you were watching the Cybertruck break new ground – and windows – in Los Angeles, here’s what was going on in the real world.

‘Halfords has launched a ONE METRE snow salt stick which quickly removes ice.’ As press release headlines go, this one goes straight to work. Note the emphasis on the size, because in the world of snow salt sticks, size matters.

Forget pointy trucks, what you need is a pointy stick. ‘The monster stick works like shake ‘n’ vac and home-owners and motorists just need to shake their stick and spread the salt over the affected area,’ claims Halfords.

Get out there and shake your stick.

Halfords snow stick

Temperatures aren’t expected to drop below freezing in Keighley over the coming days, but the biggest news in West Yorkshire is the long awaited Keighley News verdict on the new Toyota Corolla.

“Plenty of clever stuff then in arguably the best-looking Corolla so far, that continues to prove that reliable does not have to mean dull,” is the verdict. Rest easy, residents of Keighley.

Meanwhile, shoppers in Milton Keynes are being invited to enter a raffle to win a Volkswagen e-Golf, with all the proceeds going to a local charity.

Dude, where’s my Range Rover?

Literally and metaphorically, MK is a long way from LA, but that’s where we head next for the startling revelation that Hollywood actress Jennifer Garner lost her car.

Garner, who starred in the film Dude, Where’s My Car, was so traumatised by a visit to Build-A-Bear that she spent 25 minutes searching for her Range Rover. Two things: why is this news and how can you lose a Range Rover?

Maybe she needs to order a Ford Mustang Mach-E in Grabber Blue Metallic. Try losing that in a parking lot.

Speaking of parking, the Advertiser & Times reports on a Skoda Karoq driver who, in a blatant attempt to avoid car park charges, headed down to the beach. Either that or it was an unsuccessful attempt to reach the Isle of Wight without paying for a ferry.

Skoda Karoq on the beach

‘Cleans ya window screen’

There’s more. Over in the world of commercial radio, Heart has revealed how a bottle of Dr Beckmann’s carpet stain remover can treat frozen windscreens. “I’m a genius, get ya self one of these bottles, fill it with warm water and ya sorted,” said the ‘inventor’.

“No cold hands scraping anymore and it cleans ya window screen too, the brush bit is ideal.” Still want that Ford Quickclear heated windscreen? “With a salt stick and Dr Beckmann by your side, the winter blues will be a thing of the past,“ said an onlooker. Probably.

Finally, Farmer Tom might not have the social media following of Elon ‘Major Tom’ Musk, but he has come up with a very good way to stem the ‘constant tide of littering’ in the countryside. Printing car registration numbers on takeaway packaging could reduce the amount of litter thrown from car windows.

Discarded McDonald’s wrappers nestled in the roadside verges of Britain is a world away from the glitz, glamour and dry ice of a Tesla launch in Los Angeles, but it’s somehow more authentic and relevant.

More than 800 words later, you’re still here (thank you) and I still don’t have an opinion on the Tesla Cybertruck. I really ought to get my carpet cleaned, mind. Is there a doctor in the house?

New Tesla Cybertruck revealed: yes, it really looks like this

Tesla Cybertruck reveal

Looking like a vision from a sci-fi future, this is the new Tesla Cybertruck. Far from the Tesla-ified Ford F-150 pick-up we were all expecting, it seems to have been abducted from the set of the next Blade Runner film.

The reveal was genuinely frightening. As company boss Elon Musk exclaimed “So, I present to you: the Cybertruck!” smoke machines billowed and dystopian dubstep played. A YouTube commenter said “I thought four more Elons were going to get out of the truck”. At this point, would that surprise anyone?

What did surprise everyone was the styling. This jagged, otherworldly machine reminded us of the cuboidal on-board robot TARS from Interstellar. Musk’s claim that “it doesn’t look like anything else”, is certainly true.

Don’t think it isn’t serious, though. There are some very impressive real-world claims Tesla makes about the truck. Let’s first explore the stuff we’re used to talking about.

Tesla Cybertruck: the figuresTesla Cybertruck reveal

Range figures start from 250 miles for the single-motor RWD model, rising through the 300-mile dual-motor AWD to a massive 500 miles for the tri-motor AWD. Three motors suggests the top-end variant could be running a version of the PLAID powertrain Tesla has been testing at the Nurburgring in the Model S. However, no specifications for the battery sizes have been revealed thus far.

Performance ranges from a 0-60mph time of 6.5 seconds for the single-motor, to a scarcely-believable 2.9 seconds for the tri-motor. Towing capability goes from 3.4 tonnes to a massive 6.3 tonnes. The dual-motor, for the record, will hit 60mph in 4.5 seconds and tow 4.5 tonnes.

The load rating for the bed in all three models is 1.5 tonnes, with 100 cubic feet of capacity. Tesla claims it’ll be the most capable truck off-road, too, with a 35- and 28-degree approach and departure angles.

Musk also mentioned an adjustable 16 inches of ground clearance, achievable with the full air suspension and the adaptive damper system. It can drop the rear for loading, which he demonstrated with their ATV ‘Cyberquad’, as it drove up a ramp onto the bed. The truck also has an on-board air compressor, giving the air suspension system a second use.

How much will the Cybertruck cost?Tesla Cybertruck reveal

This is an area where trailblazing electric cars tend to come unstuck. Not so the Cybertruck. For the single-motor with 250 miles of range, Tesla claims you’ll pay the equivalent of £31,000 before any grants. That rises to £38,700 for the dual-motor, and £55,200 for the tri-motor. These are, of course, dollar prices converted to pounds at the current exchange rate. But you get the idea.

You can reserve one now for a fully-refundable £100 (yes, it’s in pounds on Tesla’s website). Production will ‘near’ in late 2021, while the tri-motor will arrive in late 2022 and into 2023.

The trapezoidal truckTesla Cybertruck reveal

Much as the world likes to give Elon grief, and much as he gives it cause to, he raised some interesting points about the current state of pick-up design. Fundamentally, it hasn’t changed for decades. Musk described the body-on-frame and bed-on-frame as “carried cargo, like a sack of potatoes. They don’t do anything useful”.

Looking to get away from that, the Cybertruck uses an ultra-hard cold-rolled stainless steel exoskeleton. The mass is on the outside – what you see, most of the bodywork, is also the chassis. A major benefit of this is strength, as Musk spent much of his presentation demonstrating with sledgehammers and shooting videos.

Also new is the Tesla armour glass, referred to by Musk oh-so-humbly as “see-through metal”. Although a sample survived a live drop test very well, the glass on the truck itself didn’t prove so strong. Musk didn’t like the taste of humble pie, shouting expletives as the glass smashed. “There’s room for improvement,” he followed.

Tesla Cybertruck reveal

Other observations? That slab top that goes from the windscreen to the end of the loadbed appears to roll and fold away like shutters. In the ATV demonstration, it rolls into storage at the point where the bed meets the cabin.

The inside is tame by comparison with the exterior. Seating for six is available, as per pick-up convention. The steering wheel looks to be borrowed from the Roadster supercar (still unreleased) and the 17-inch screen is very much in the style of the Model 3.

Tesla Cybertruck reveal

We do have some queries. For one, the design doesn’t look too pedestrian-friendly. We’d love to hear what Euro NCAP thinks of it, and indeed how it performs in a wind tunnel. Also, given the ‘chassis is the body’ design, how much will it cost to repair after an accident? Food for thought. That’s all to come, though.

For now, Tesla has yet again reminded us why it’s so often referred to as a ‘market disruptor’. Mock Musk and his endeavours all you want, but he knows how to grab a headline. He also seems more like a Bond villain with every passing day, and he’d probably take that as a compliment.

Tesla gets top score in low-carbon assessment

Tesla Moody's carbon assessment

Electric automaker Tesla has received top marks in an environmental impact study. The Carbon Transitional Assessment (CTA) score is awarded by research and analytics group Moody’s, and measures how effectively a marque is transitioning to low carbon cars.

In the assessment of 20 car manufacturers, Tesla was the only brand to receive a top CT-1 score, with the lowest possible rating being CT-9. BMW, Honda, Geely and Toyota all got respectable marks, thanks to their low-emissions models.

Tesla Moody's carbon assessment

“Our new assessment gives us a way of monitoring progress in aligning with the low carbon transition,” said vice president of Moody’s, James Leaton. 

“2020 is set to be a critical year for automakers proving whether they can deliver electric vehicles at scale to achieve compliance in Europe and China.”

Moody’s says that car manufacturers should be aim to electrify at least a quarter of their fleets, in order to meet guidelines for sustainability set by the International Energy Agency.

Tesla misses out on top-10 sales spot

Tesla’s introduction of the Model 3 into the European market has markedly increased EV uptake. In September, the new all-electric executive car was Europe’s 11th best-seller. Tesla’s market share for EVs in Europe is nearly 50 percent. 

Meanwhile, in the second-hand market, it was recently revealed that the all-electric Renault Zoe is the UK’s fastest-selling used car

Tesla Model 3 is 11th bestselling car in Europe

Tesla misses out on top-10 sales spot

September 2019 was a bittersweet month for Tesla. While it was the best month for Model 3 sales since launch, the electric car just missed a top 10 European sales spot. 

According to JATO figures, 17,505 Model 3s were delivered in Europe in September. It misses out on 10th place by just 217 units, behind the Renault Captur.

It’s the first time an electric car has come so close to Europe’s top 10. September’s overall bestsellers in Europe were the Volkswagen Golf, Vauxhall Corsa and Renault Clio.

In terms of market share, Tesla should be pleased. A total of 19,500 cars registered in September gives the EV manufacturer nearly half of the Battery Electric Vehicle (BEV) market.

What powered September 2019’s new cars?

Tesla misses out on top-10 sales spot

In terms of fuel type, September 2019 sees petrol climb from 58 percent to 59 percent market share. Meanwhile, alternative-fuel vehicles have grown from 7.8 percent to 10 percent. Diesel has dropped again, from 33 percent to 29 percent.

Hybrids have seen a sales growth of 32 percent, while plug-in vehicle sales have grown by 28 percent. Predictably, the Model 3’s success has inflated electric vehicle sales growth massively. Year-on-year, electric cars are up a massive 120 percent.

Overall car sales up 14 percent

As for overall sales, there was a 14 percent jump in year-on-year comparisons. However, the negative impact the WLTP deadline had on September 2018 means that last month’s figures look unusually strong. A 23 percent drop was registered last year, compared with September 2017.

Tesla misses out on top-10 sales spot

The overall growth posted in August-September indicates that, despite the market’s new challenges, consumer demand continues to be strong in Europe,” said Felipe Munoz, JATO’s global analyst.

“This is a good sign for the coming months, when the looming CO2 targets become even more pressing for the industry.

“Despite the negative views about the state of the industry, the data shows that we still have a healthy European car market – although there are many challenges heading its way, of course.”

Why are some Teslas ‘dead’ after five years?

Tesla dead after four years

We’re used to short-term obsolescence with smartphones, but is it acceptable in cars? Would you be happy if the Tesla you paid six figures for five years ago is now immobile?

We suspect not. But that’s the reality some early adopters are facing, as the very earliest models from the electric car manufacturer are losing their charging capability.

It brings to the fore a looming question about the company that, excluding the original Lotus-based Tesla Roadster, has been only selling cars for seven years. What is long-term reliability like? A report by Business Insider suggests some worrying problems.

What is killing Teslas in five years?

Tesla dead after four years

The issue appears to be with the car’s on-board flash storage, which gets overloaded and leaves the car unable to charge, or load up its all-controlling screen. And no, an over-the-air update won’t currently fix this one.

The chip is called the eMMC, installed on the car’s MCU1 (Media Control Unit) component. It’s the kind of temporary memory that other digital gadgets have. It writes, erases, and re-writes memory to assist with performing tasks.

In the case of Tesla, according to repairers, the eMMC is working overtime writing vehicle logs. With a finite number of writes available, these chips are being burnt out by the car’s consistent volume and speed of data-logging. “The amount of logging they’re doing is excessive,” a Tesla repair professional has said.

So when does this happen? According to the expert quoted by Business Insider, don’t be surprised if you see issues on or after the four-year mark. One contributor to the Tesla Forum said they were awaiting an MCU replacement, under warranty, after just 26,000 miles and less than two years. 

Even Tesla boss Elon Musk seems confused. An expert, who has taken it upon himself to analyse some of these repairs, appealed to Musk on Twitter about the failing components. The CEO responded: “Should be much better at this point”. It sounds like his expectations for the longevity of the hardware were higher.

Is the problem as bad as it sounds?

Tesla dead after four years

The discourse around Tesla is rarely balanced, either evangelising or demonising the controversial marque. We’ve tried to stay as neutral as possible.

This doesn’t sound like an absolute car-ending issue. Indeed, the above expert has been carrying out repairs and fixing cars, which confirms as much. Tesla itself has also been carrying out this work. 

Does the issue compare more with something like engine detonation, or a service-interval item? In terms of expense, sadly, it’s more the former. We hear of low-to-mid four-figure replacement costs. Given ‘MCU’ is short for Media Control Unit, safe to say it’s a dashboard-out job to replace.

Tesla dead after four years

Then, we have to come back to software. If hardware replacements are expensive and difficult, is prevention just a software patch away? Could a recall, followed by an update, erase this issue out of existence? Tesla would have us believe anything can be fixed with an over-the-air update. We certainly hope so. It could prove to be the most important software patch the marque puts out.

Tesla replaced MCU1 with MCU2 in cars built in the latter half of 2018, with Intel replacing Nvidia hardware. It speeds up the response of the screen and allows features like Tesla Arcade, dashcam functionality and Sentry Mode. What isn’t clear is whether MCU2 has a similar memory writing issue.

Opinion: Tesla needs to take action

Electric cars most reliable

It’s easy to make the comparison with phones, but Teslas are much more expensive, and a longer lifetime is thus expected of them. They need to be repairable, even upgradable, and they need to last the course as a normal car would. 

Yes, it’s worrying that a car that can be allegedly fixed with software updates is going ‘dead’ after four-to-five years. And even Elon Musk seems a little lost for words (there’s a first time for everything). We wonder, however, whether this won’t be looked back on in 10 years as a teething problem, for a company that, we must remember, is still very new.

However, it’s also expensive, inconvenient and could be a real turn-off for buyers, plus a killer of used Tesla values. So Tesla needs to come clean, and mitigate costs for owners or retroactively extend warranties. Hopefully, there’s a software fix for those not yet affected. Short term, cars are ending up ‘dead’. Long term, if handled properly, this isn’t the death knell for Tesla.
