Suzuki and Toyota achieve ‘faultless’ reliability – but Tesla comes out BOTTOM

2018 What Car? Reliability Survey reveals sees two cars achieve perfect 100 percent scores

Suzuki SX4 S-CrossThe Suzuki SX-4 S-Cross and Toyota Yaris have both achieved remarkable 100 percent reliability scores in the latest What Car? reader survey – in stark contrast to the Tesla Model S, which barely scored a 50 percent reliability ranking.

The results show that four of the top five cars are from Japanese brands. Of the bottom five, Land Rover makes three of them, with Ford and Tesla joining the worst-ranking makers.

Toyota Yaris

It is the 2013 – present Suzuki SX4 S-Cross and 2011 – present Toyota Yaris that achieved the ‘perfect reliability’ ranking. The all-electric first-generation Nissan Leaf (built between 2011 – 2017) was third, with a 99.7 percent reliability ranking.

The Leaf showed that it wasn’t the all-electric aspect of the 2013 – present Tesla Model S that was behind its dismal reliability score…

Tesla Model S

What Car? ranked 159 models from 31 brands for reliability in 2018. “Reliability is a huge consideration for any prospective car buyer,” said editor Steve Huntingford, “as your car is likely to be your second biggest monthly expense after mortgage or rent payments.

“Our annual survey has shown that it is Japanese models that continue to dominate the top of the reliability rankings, both for car model and brand rankings.”

What Car? worked out its reliability ranking from data from over 18,000 motorists. They reported on their car’s reliability over the past 12 months; the magazine then created a unique reliability ranking for reach model – which included aspects such as time off the road and cost of repair.
