Example complaints

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

“When accelerating the car trips into neutral and will not let me continue accelerating. I can push the pedal all the way to the floor and nothing will happen. The only way it trips out of neutral is to release the pedal and then push it again. This happens when already driving around 10-30mph not from a stopped position and was on city streets. It does also happen when turning.”

I first seen the codes as I was entering the expressway at approximately 35 MPH 1 week after getting a new battery.”

“The vehicle is shaking at highway speeds , I have replaced the tires ,brakes , rims and the vehicle I am told from the dealer that my vehicle doesn't apply to known issue and there's nothing I can about it , I have had it balanced and road forced tested with no relief it's a concern as the vehicle instability has caused for new hubs and already on a vehicle less than 50k on the mileage”

“Hard shifts on 1st to 2nd and 2nd to 3rd causing whiplash-like reaction. Shifts occurs after what it seems to be a pause in acceleration then engine revs for 500 to 1k RPM before shifting, then the car will lunge forward. Acura has performed software updates. It reduced the hard shifts but it is still there. I have to tighten my neck and brace for a hardshift I know is coming.”
