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.”

NHTSA complaint #11366155, filed 2020-10, 146,817 miles

“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 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.”

NHTSA complaint #11119974, filed 2018-08, 75,000 miles

“I parked my car at home and shut it off. I immediately attempted to restart it in order to adjust the car's position, and found that the interior lights would come on, but not the engine. 3 dash lights--engine, battery, and I don't remember the third one--remained lit. Took it in to the dealership the following monday (10/19), and they replaced the starter.”
