Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Every time I fill up my tank with gasoline, once I park in the garage, the garage is filled with strong gas fumes from my car. I checked for leaks under the car and found nothing. I have to raise the garage door to let the fumes out, due to getting lightheaded from the fumes. The fumes remain with the car for 7-10 days. This has been going on for the past four years. This problem is a danger to my family's health!!!! Surely, there is a recall on this problem! 2nd issue: I turned my car off and the fan kept running. …”
