Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was driving on a highway getting off an exit, and I had my kids in my car and all of a sudden as I am slowing down to come to a stop to turn off the exit my car steering and brakes locked up and everything shut down. Luckily I live in walking distance to the exit ramp because someone stopped and helped me push my car to my house. They had to put it in neutral but it was extremely hard to move the steering wheel. Never had any issues with leaks or anything like this. The car smelled like antifreeze and was running hot. I let it cool off. It was the water pump that was leaking and went out. …”
