Example complaints

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

“After about 60,000 miles my check engine light illuminates with code p0012 every 1,000 miles and when I take it to technician they find nothing wrong after resetting. Then again it randomly appears and has been doing such for the last 10,000 miles. Frustrating. Also the front brakes squeal everytime I touch the brake pedal regardless of which pads I use or if they are new or used.”

“Vehicle stopped abruptly with a shake while reducing speed at a traffic signal. I was in the middle of the road. A mild burning smell came out from the hood. The car was serviced one month back and as part of it they did 128 point( do not remember exact number ) and all reported issues were fixed. Around $1000/- was spent on the car. Since battery was just 1 year old, I did not expect a problem with the battery as well. Still I switched off all lights and tried to restart. There was no further response from the vehicle. I was blocking traffic from behind and police came to control traffic. …”
