Example complaints

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

“When using turn signals car dies, all the dash lights flash and click. If I pull over and put the car in park it restarts and drives fine until I try the turn signal again then the same thing happens. I also had to disconnect the emergency brake sensor or else the same thing happens. Flashing, clicking and car dies. Now, whenever car is in gear, constant dinging and it will drive fine but I cannot use the turn signals.”
