Example complaints

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

“I have been experiencing failures from my speed control. It moves slow on it own regardless of how high the meter says. When braking the car shakes and then on its own it goes off and all the lights on the dashboard comes on. This has happened to me 3 times on the highway. The engine light also came on recently and now my car vibrates/ shakes when idle or when it starts.”

“Just bought the car a couple weeks ago for my daughter. The car was parked in a parking lot and would not start. Tried jumping it. Changed battery in key. Gas tank was full. Finally looked on internet and finally looked on line and found a lot of others had the same problem. They said to push the car from the rear. We did and it started. Afraid my daughter will be stuck at night leaving work.”

“Car was parked and completely off. I put the key in the ignition and turned it partway. All electronic components and headlights came on. I turned the key all the way and it would not start. There was a loud rythmic clicking and each time it clicked all the electronics flickered. Jumping the battery did not work.”

“Takata recall: my car will rev the engine really high over and over again on its own rather than idle while in park. Also while in drive and the break pressed, the engine will rev on its own likes its trying to move forward without me pressing the gas pedal. This is dangerous. This has happened on multiple occassions not just what is noted below.”

NHTSA complaint #11129458, filed 2018-09, 99,514 miles

“Takata recall car doesn't want to start and struggles to do so. Have replaced battery and key fob batteries. This has to be a starter issue, possibly an electrical short. Says key out while I'm driving it half the time. I am afraid it will cut off while I'm driving it! I have only had the car for 2 years! Been doing this for about 2 months.”
