Example complaints

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

“Electric door locks have increasingly become a problem. First, the front passenger side stopped working and now has to be manually locked and unlocked. Then the same happened to the passenger side rear, which has to be locked and unlocked manually. Finally, the driver's door has on three occasions, locked me in, forcing me to roll down the window and use my key to get out of the vehicle. I've never had anything like this happen w/ any of the other vehicles I've owned.”

I checked all the fluids, they were at operating levels. I performed a visual check under the car and hood for fluid leaks. There were none. I called a nearby (40 miles) toyota dealer who dispatched a tow truck to pick us up and bring the car to their repair center in delaware ohio. …”
