Most reliable hybrid cars - and the ones to avoid

Hybrid cars have come a long way since the arrival of the Toyota Prius in 2000. There are now hybrid and plug-in hybrid versions of many new car models that have the potential to save money on fuel, particularly if you do mostly urban or short driving. 

The other plus point about hybrids is that they’re proving impressively robust in spite of the added complexity of dual power systems. In the latest What Car? Reliability Survey only 17% of the plug-in hybrids (PHEVs) reported on had any issues, and that percentage only rose to just 18% for regular hybrid cars. In comparison, 26% of diesel and electric models went wrong. You can read more about those in our most reliable diesel car and most reliable electric car articles.

How the research was carried out

To compile the latest What Car? Reliability Survey we asked 21,732 car owners to give us the lowdown on how reliable their car had been over the previous 24 months. First we asked them to tell us if the car had suffered any problems, and, if so, how much each one had cost to put right and how long it had kept the car off the road.

The survey, conducted in association with MotorEasy, was compiled using this information. It contains data on 178 models aged up to five years old from 32 different car brands.

Most reliable hybrid cars 

1. Suzuki Vitara Hybrid (2015-present)

Reliability rating 100%

The Suzuki Vitara is available as a regular hybrid and a mild hybrid. While both are a great option if you’re after a dependable small SUV, it’s the pure hybrid that comes out on top. The mild hybrid version scores a creditable 96.7%, but the pure hybrid trumps it with a maximum 100% rating. That means not a single owner reported a fault with their car.   

2. Lexus NX (2014-2021)

Reliability rating 99.8%

The larger 2014-2021 Lexus NX isn’t far behind the Vitara with a rating of 99.8%. Just 2% of owners said their cars had suffered any hiccups, and all issues were resolved in a day or less by dealerships at no cost to owners. That makes it the highest scoring family SUV for reliability. 

3. Lexus NX Hybrid and PHEV (2021-present) 

Reliability rating 99.4%

The latest Lexus NX isn't quite as bulletproof as its predecessor, but it's pretty close. Only 5% of the cars we were told about went wrong, and all the faulty cars remained driveable and were fixed in a day or less. Even better, no one was landed with a repair bill.   

=4. Toyota Yaris (2011-2020) 

Reliability rating 99.3%

The 2011-2020 Toyota Yaris is proof that you don't have to buy a big, expensive car to get a dependable model. A mere 3% of Yaris owners told us their car had any sort of trouble, and the only area concerned was the 12-volt battery. Although the faults rendered all affected cars undriveable, all were fixed in a day or less, and at no cost to owners. 

=4. Lexus UX (2019-present)  

Reliability rating 99.3%

The UX is the smaller sibling of the NX, and it's another Lexus family SUV with a top-notch reliability record. Only 3% of the cars reported on in our survey had any issues, and the only area to give any grief was the sat-nav/infotainment system. All remedial work was carried out for free, but all cars were out of action for more than a week while being fixed.  

=6. Hyundai Ioniq Hybrid (2016-2022)  

Reliability rating 99.2%

The Hyundai Ioniq is available as a hybrid, PHEV and pure electric model. The hybrid options are far more dependable than the electric versions - the latter only achieved a reliablity rating of 75.5% and had a fault rate of 41%, compaed with 5% for the hybrids.

The only area on Ioniq Hybrid models where there were problems was the sat-nav/infotainment system. Owners were well cared for, too, with all issues rectified within a day and at no cost. 

=6. Volvo XC40 PHEV (2017-present)  

Reliability rating 99.2%

The Volvo XC40 may be one of the brand's smaller SUVs, but it's big on durability, with only 7% of the cars we were told about having any faults. Petrol XC40s are less robust, with a fault rate of 22%. The interior trim was the only weak spot, and 50% of cars took up to a week to fix, but Volvo carried out all remedial work for free.    

8. Kia Niro Hybrid and PHEV (2016-2022)  

Reliability rating 98.8%

There are two options if you’re considering a 2016-2022 Kia Niro hybrid, and owners say both the conventional hybrid and the plug-in hybrid are equally dependable. Just 5% of the hybrid models we were told about had any issues – that’s three times less than the pure electric Niro EV. 

There were a small number of issues with the 12-volt battery, interior trim and electric motor. However, all faulty cars were fixed in a day or less and all work was done for free.   

9. Toyota RAV4 (2019-present)  

Reliability rating 98.7%

The latest generation Toyota RAV4 is only offered as a hybrid or PHEV, which is no bad thing because it's an economical an hugely reliable option. Only 3% of the cars we heard about had gone wrong, and the 12-volt battery was the only cause of concern. 

Remedial work wasn’t always swift: half of the faulty cars took up to seven days to put right and a quarter were out of action for more than a week. Three-quarters of work was done for free, but the remainder cost owners up to £200.

10. Toyota Yaris Hybrid (2020-present)  

Reliability rating 98.6%

The latest Toyota Yaris is outclassed by its predecessor when it comes to reliability, but not by much, and it's still one of the most robust small hatchbacks you can buy. Only 6% of the cars reported on had any glitches, and they were only minor issues with the engine electrics. Although Toyota paid for all repairs, all the faulty cars spent more than a week in the workshop. 

Least reliable hybrid cars

1. Range Rover Evoque PHEV (2019-present) 

Reliability rating 58.6%

Plug-in hybrid versions of the Range Rover Evoque aren’t as robust as other variants because they suffer more faults that are time-consuming to put right. Two-thirds of the Evoque PHEVs in our survey went wrong, with electrical issues the most common complaint, followed by problems with the engine and bodywork. Although most (92%) of cars were fixed for free, three-quarters of faulty cars were in the workshop for more than a week.  

2. Volkswagen Golf PHEV (2020-present)

Reliability rating 79.3%

Plug-in hybrid versions of the Volkswagen Golf were marginally better for reliability than their petrol counterparts. Both variants have a fault rate of 48%, with lots of reports of electrical issues, and 47% of the hybrids took more than a week to fix. However, while some petrol Golf owners had to find more than £1500 for repairs, all hybrid models were fixed for free.    

3. Mercedes A-Class PHEV (2018-present)

Reliability rating 87.5%

Plug-in hybrid versions of the Mercedes A-Class are a better bet than their petrol or diesel counterparts. Although all three variants have a fault rate in excess of 30%, 27% of hybrids remained driveable and were fixed in a day or less, while more than half of petrol and diesel models sat in the garage for more than a week. Not such good news is that 9% of hybrid owners had to pay more than £1500 for repairs, while repair bills were lower for petrol and diesel A-Class owners.
