Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While driving on Back Rd in New Hampshire at approximately 30 mph on Saturday, Feb 14, the vehicle suddenly lost power steering assist and simultaneously shifted into neutral. I received warning messages and immediately lost propulsion. Luckily, there was no traffic on the road with me, but that is not always the case on this particular road. I had to manually steer the vehicle without power assist and muscle it to the side of the roadway. The vehicle was disabled in the road and required towing. …”
NHTSA complaint #11718508, filed 2026-02“The DC converter went bad and within 30 seconds while driving on the highway I got a battery warning and then the car went into neutral and stopped and went into park and the car turned off in the middle of the road and couldn’t be moved at all. Luckily some cops came and protected the car from behind until a tow truck came. The part needed is out of stock and may not be in stock for months!”
