Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I bought the car yesterday, and today realized the car is leaking fuel, pooling under the back seat and spilling out under the car. The passenger headlight will not work; we tried 3 bulbs. The panel displays a message stating one of the tag lights is out, but it actually works.”
NHTSA complaint #10914366, filed 2016-10, 134,000 miles“I was always getting an error message telling me my rear lights were not working. I experienced an electrical fire in my trunk, which caused the air bags to deploy and the entire left side of my car caught fire. The car was totaled. Car would not start, trunk would not open. Car was totaled by dealer and insurance company. I know there is a recall notice for new c class cars, but because of what I experienced, I believe older models may also have the same problem.”
NHTSA complaint #10586324, filed 2014-05“I don't know that my car was a recall and when I first got it my gas gauge when out and stuff start to go bad. The car place I purchase the car from knew all this stuff and don't inform me at all. I know I bought a used car but I was hope they will let me know . Now that my warranty up they is giving the run always . What should about it . So when I go put gas in my car I don't know how much gas it is in my car because my gas read and meter in the car don't work and also have a short in it.”
