Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“While driving, there is a random ding. No idiot lights come on this has been going on for over a month. Today I happened to look up and the passenger airbag light was flashing. As if stating there was someone in the seat. The only way to stop it is to have the passenger seat belt buckled while driving. This only happens while driving. It is very disturbing because I am not sure if I am in an accident if my passenger will be safe.”

NHTSA complaint #11270319, filed 2019-10, 136,024 miles

“I am having trouble with these things now. The powertrain especially I have not had accident yet but it keeps going dead on me in the middle of driving down road. Causing me to have to put in neutral and restart. At this time the steering goes out. This needs to be repaired before an accident does happen. The drivers seat does not move forward or backwards. The tire pressure warning does not warn until it is at 20 psi.”
