J.D. Power Vehicle Dependability Study 2021 reveals most reliable cars

Some people – or, in this case, cars – have everything going for them.

The Porsche 911 is one of them. The sports car, which is often listed as one of the most collectible vehicles in the auto industry, can now add another accolade to its trophy case: most dependable.

The Porsche 911 ranks as the best performer in J.D. Power’s 2021 U.S. Vehicle Dependability Study, a closely followed annual list that automakers often trumpet in their marketing campaigns.

It’s not a big surprise. The Porsche brand overall ranked as the second most dependable lineup of vehicles, trailing only Lexus, Toyota’s luxury brand.

But you don’t have to buy a luxury car to get a reliable ride these days. In fact, vehicle dependability reached an all-time in the 2021 study as the number of problems reported by owners fell by 10% from the previous year.

The 32nd annual study tracks 177 specific problems in eight categories, including powertrain issues, exterior flaws, infotainment defects and HVAC problems.

J.D. Power ranked the Toyota Tundra as the most dependable large light-duty pickup in its 2021 Vehicle Dependability Study, which assessed the 2018 model year. The 2020 Tundra TRD Pro is seen here.

This year’s study assesses the 2018 model year, allowing for three years of road experience to assess how 33,251 owners say their vehicles have held up.

On average, owners reported 121 problems per 100 vehicles, down from 134 in 2020.

Lexus was best at 81, Porsche second at 86, Kia third at 97, Toyota fourth at 98 and Buick and Cadillac tied for fifth at 100.

Tesla was assessed for the first time and had more problems than all but three brands: Jaguar, Alfa Romeo and Land Rover. Owners reported 176 problems for every 100 Tesla vehicles.

J.D. Power also names the most dependable model in each major vehicle segment. Toyota won five categories, while General Motors won four and Hyundai four. (Scroll down for the full list.)
