What Are The Most Reliable Electric Vehicles?

The British firm that sells warranties for used vehicles, Warranty Solutions Group (WSG), analyzed over 2,500 warranty disputes for used electric cars between May 2025 and April 2026, according to the Daily Mail.

There is a big difference in the reliability of electric vehicles. If you own an older Tesla Model S (from the 2014 model year), 34.8 percent of owners were forced to visit a garage for repairs during the warranty period in the past year. The average cost of repairing breakdowns on a sedan was £1,012. The brand’s large SUV, the Tesla Model X, also ranks at the bottom with a 29.2 percent failure margin. German Mercedes is also under fire with its EQ models; the EQV family van has a failure rate of as high as 33.3 percent. The SUV EQB is also in breakdowns with 25.7 percent, and close behind is the Volkswagen e-Up! with 24.8 percent failures.

At the other end of the spectrum, we find much cheaper and simpler electric cars. The absolute winner in the survey is the small French car Renault Zoe (produced between 2012 and 2023). Only 1.5 percent of Zoe owners had to use their used car warranty during the year. When something did break, the repair was also cheap, averaging just £130. Even the pioneering BMW i3 demonstrates outstanding engineering with a low failure rate of 2.2 percent. The newer and very popular SUV Tesla Model Y takes an impressive fifth place on the list of most reliable cars, with only 3.3 percent of owners affected. However, it should be added that these cars are significantly newer, and many are still covered by Tesla’s new car warranties. The MG ZS and Nissan Leaf are also excellent.

Perhaps the biggest surprise in the report is that an expensive high-voltage battery is rarely the reason for a service visit. The industry has long warned about battery failures, but warranty data show that failures in older electric cars are linked to other components. What breaks down most often is the electronics. The most common failure is a defective central locking system (4.29 percent of all damages), followed by a defective tailgate (3.6 percent) and worn suspension arms (2.9 percent). However, the breakdowns that are the absolute most expensive occur when the battery charging system fails. The average cost of a repair is £1,882.
