Most and least reliable used cars: electric and hybrid cars

We name the most dependable – and most troublesome – used cars aged from six to 20 years old, based on owners’ experiences...

Kia Niro Hybrid

The most reliable electric and hybrid cars

1. Kia Niro Hybrid (2016-2022)

Reliability rating 100%

The Niro family SUV may look rather conventional but it has a trick up its sleeve – it's exceptionally reliable. In fact, not one of the Niro owners who completed our reliability survey reported a fault with their car. That means nobody was landed with an unexpected repair bill.

2. Lexus CT (2011-present)

Reliability rating 99.2%

Lexus CT front three quarters

The CT family car upholds Lexus’s excellent reputation for dependability. A mere 3% of the cars in our survey went wrong, and the only area of concern was non-engine electrical systems. All cars could still be driven, and all issues were resolved in a day or less. Although Lexus didn't cover the cost of any repairs, all bills were less than £100.

3. Lexus IS (2013-2021)

Reliability rating 97.7%

Lexus IS

The third-generation IS was rather radical when it went on sale as either a petrol or hybrid model, with no diesel option. However, it's still a luxurious compact executive car with high-tech engineering and exceptional reliability. The air-con and battery were the only trouble-spots identified by the 5% of IS owners whose cars suffered a fault. Lexus covered the cost of two thirds of repairs, and no one paid more than £200. The only negative: a third of cars couldn't be driven and were out of action for more than a week.

3. Toyota Prius (2009-2015)

Reliability rating 88.5%

Toyota Prius

The Prius is only in the bottom three because this is such as high-scoring class. Only 14% of the examples we were told about suffered a fault, with the air-con and 12V battery giving the main causes for concern. Repairs were fairly slow, though. Only a third of cars were fixed in a day or less, and two thirds were out of action for more than a week. Repair bills ranged from £101 to £1000. 

2. Tesla Model S (2014-present)

Reliability rating 67.5%

Tesla Model S

The Model S is the least robust model in Tesla's line-up, with 64% of the owners in our survey reporting that their car had suffered a fault. Bodywork, the 12V battery and non-motor electrics were the most common complaints, followed by issues with the air-con, interior trim and suspension. Most cars could still be driven, though, and 45% were fixed in a day or less. Although 53% of cars were fixed for free, 40% of owners paid out up to £750 and 3% paid out more than £1500.

1. Lexus RX (2009-2016)

Reliability rating 61.6%

Lexus RX

The 12V battery and suspension were the main bugbears of the 16% of RX owners whose cars suffered a glitch. A third of cars were rendered undriveable by faults, but 60% were fixed in a day or less and the rest in less than a week. Impressively, Lexus covered the cost of 33% of repairs, but that left the rest of the owners with bills ranging from £101 to £1000.
