Most and least reliable electric and hybrid cars

The three least reliable electric and hybrid cars

3. Toyota Prius (2016-present)

Toyota Prius 2020 RHD front cornering

Reliability rating 94.6%

Despite being in the bottom three (and the worst-performing hybrid we were told about), the Prius's reliability record is actually pretty good; it's just that rivals are even more bulletproof. Prius owners reported a fault on 14% of cars, but half of repair work was done for free and the rest cost £50 or less.

2. MG ZS EV (2019-present)

MG ZS EV front three quarters

Reliability rating 89.4%

The fully electric ZS EV went wrong in only 7% of cases, but all of those cars were rendered undriveable and took more than a week to repair. Problem areas included the battery, electric motor and non-engine electrics. The good news is that all of the faulty cars were fixed under warranty.

1. Tesla Model S (2014-present)

Tesla Model S front action - 69-plate car

Reliability rating 85.7%

The Model S suffered the highest percentage of faults in our entire 2020 Reliability Survey, with 60% of the cars we were told about having a problem. Although all of them could still be driven, half were out of action for more than a week. And while 93% were fixed for free, the remaining owners paid out between £50 and £100 for repairs.
