Warranty company reveals the largest bills paid in 2017Buy a new car and it’s likely to come with a three-year warranty, but many manufacturers will offer extended warranties for an additional premium. Alternatively, some new cars will be covered for five or even seven years, providing peace of mind until as late as 2025. But what do you do when the warranty expires?

You’re faced with three choices: sell the car, chance your arm, or opt for an aftermarket warranty. Typically, you’ll pay anything from £100 to £500 a year, but in return you’ll be covered in the event of the failure of mechanical or electrical parts. Warrantywise has just released details of the top 10 car repair bills it paid in 2017, and the costs will send shockwaves through your wallet. All photos used are for illustrative purposes only.

10: Audi TT engine (£5,084)

It’s worth pointing out that not all aftermarket car warranties are created equal. There are a number of different options out there, offering various levels of protection. Many will cover the major mechanical and electrical parts, but others might include protection against MOT failure and multimedia malfunction. In 2017, Warrantywise paid just over £5,000 when an engine failed on an Audi TT.

9: Mercedes-Benz C-Class sensors (£5,134)

A similar figure was paid out for failure of the sensors on a Mercedes-Benz C-Class. We took a look on the Warrantywise website, where we were quoted £2,000 for a three-year warranty on a 2014 Mercedes-Benz C220. This includes a garage labour rate of up to £35 an hour and a single repair limit of £5,000. Increase these rates, and add the likes of multimedia, MOT and emissions cover to the package, and the cost will increase.

8: Porsche Cayenne oil leak (£5,494.38)

Even something that appears to be a relatively minor issue can cost an arm and a leg to repair, like the £5,500 it cost to repair the oil leak on a Porsche Cayenne. If this doesn’t encourage you to investigate the cause of that puddle on your driveway, nothing will.

7. Ferrari 599 gearbox (£5,745.22)

Warranty company reveals the largest bills paid in 2017

You wouldn’t buy a Ferrari 599 expecting to see running costs on a par with a Ford Fiesta, but finding £5,745 at the drop of a hat would be a stretch for most people. The Warrantywise website features a handy tool which provides an insight into the items most likely to go wrong on each car. The Ferrari dropdown menu includes everything from a 575M F1 gearbox (£6,161.21) to a 430 sensor (£2,171.09).

6. Lamborghini Aventador clutch (£5,954.02)

But it’s important to stress that big bills aren’t the preserve of exotic supercars. Warrantywise paid an eye-watering £453.29 for a brake caliper for a Daewoo Kalos and £431.10 on a heater matrix for a Daewoo Tacuma. A latch on a Proton GEN-2 cost £320.03, while a new engine on a Kia Sorento weighed in at £2,950. Not quite Aventador clutch money, but in relative terms it’s quite a chunk.

5. Maybach 62S brakes (£6,110.94)

The Maybach 62S is a lumbering beast of car, so you need to ensure the brakes are up to scratch. Spending £6,110 on the braking system should ensure the anchors are fit for purpose. Speaking of luxury motors, we took at look at Rolls-Royce, and discovered that Warrantywise has paid out for repair bills of up to £3,619.74 on the Phantom.

4. Dodge Journey gearbox (£6,262.54)

Yes, somebody in the UK actually bought a Dodge Journey, and when the gearbox went, they probably wish they hadn’t. Fortunately for them, Warrantywise covered the cost, which came in at a staggering £6,262. There are many faults listed under the heading of ‘Dodge’, so a warranty is likely to be a good move.

3. Nissan GT-R gearbox (£6,271.38)

On this evidence, the Nissan GT-R is a supercar-tamer with supercar-rivalling costs, should things go wrong. In addition to the £6,271 paid out in 2017, Warrantywise has previously forked out £9,500 and £6,187 for two separate gearboxes, and £4,890 for various engine faults.

2. Land Rover Discovery 4 engine (£8,527.80)

Warranty company reveals the largest bills paid in 2017

The Warrantywise website makes for grim reading for anyone who has recently purchased a used Land Rover. The Range Rover Sport looks particularly troublesome, with the table filled with bills upwards of £2,200. But each one is dwarfed by the £8,527.80 claim for a new Discovery 4 engine in 2017. Ouch.

1. McLaren MP4-12C gearbox (£10,000)

Warranty company reveals the largest bills paid in 2017

Imagine being faced with the prospect of a new gearbox on a McLaren MP4-12C. We suspect that the round figure is based on the upper limit of the warranty cover, which would suggest that the final bill was even higher. MP4-12C owners might want to wrap their seven-speed dual clutch gearbox in cotton wool.
