Example complaints

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

“We have sporadic problems with engine or transmission and the dealer has not been able to identify the problem. It happens at any time slow or fast speed: uphill or downhill the car will not change gears and starts to pull as if the transmission is going to fall out. We have reported this to Acura customer service and results were guarded. I am afraid for my and my family's safety because the problem continues and it happens anytime and anywhere. It happened today and we called the dealer to come and pick up the car.”

Smoke was now visible, coming from the engine (under the hood). I was able to move from the middle lane to the right lane/exit lane as I knew I needed to pull over immediately. Since I was in an exit lane there was no real shoulder and I started down the exit ramp. The smoke was very strong at this point. …”
