Sample complaint excerpts
High-Voltage Battery
- [2023] The car warning flashes “drivetrain fault”. Then after about 5 seconds the car put itself into neutral and started to slow down. I pulled off to the side of the highway before it stopped on its own . I was not able to start the car back up. I got it towed to the dealership . I am told that the AC compressor failure to the high voltage battery system , shut down the system . Seems very dange
Electric Propulsion
- [2024] This is has been continuous, yesterday my car braked on the freeway. Suddenly with no obstruction. The car behind me almost crashed into me and it would’ve been a very tragic event. I took it to the dealership and they don’t do anything, all they do is give it back to me. Yesterday also has loss of power too. I have alerted them many times, they keep saying to take it in but they don’t do anything
Source: classified from NHTSA complaint and recall data. "Battery-related" includes high-voltage propulsion battery, charging system, hybrid drivetrain, electric propulsion, regenerative braking, 12V auxiliary battery, and thermal-event complaints. Other complaints (suspension, steering, brakes, infotainment) appear in the engine and vehicle-level sections. Rates are absolute counts, not normalized per-VIN — high-volume models naturally produce more raw complaints than low-volume ones. Self-reported death and injury counts are capped per complaint to limit form abuse.
