Example complaints

Fuel system: “The message hybrid system failure suddenly displayed and the vehicle lost power and stalled. This occured on hyw (65mph) and nearly caused wreck from behind”

NHTSA complaint #11365546, filed 2020-10, 24,922 miles

Electrical system: “The high voltage battery will no longer charge neither from being plugged in to the charger on the wall nor from the buikt in system onboard the car. There are warning lights saying the inverter coolant is low but the reservoir is at the proper level. I suspect the coolant for the Hybrid charging inverter is bad and crystalizes causing blockages in the inverter coolant system. My car refuses to charge for the last 2 years. After a few seconds (about 7-10) the car shuts off the charging system when plugged in. …”

NHTSA complaint #11752871, filed 2026-07

Transmission and drivetrain: “I was traveling on a highway when a hybrid system warning suddenly appeared on the dashboard. Every dashboard warning light illuminated. The car began to lose power. I exited the highway immediately and the car began to have sporadic power and was lurching. I immediately pulled onto the shoulder and at that time another warning on the dash appeared within a minute or two of the first warning that said shut engine off. The computer screen began to flash on and of and the windows would not roll up smoothly. When the tow truck arrived the car wouldn't start and it didn't recognize the key fob. …”
