Example complaints

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

“I parked my car with an almost full tank of gas while I was at work. After leaving work, I started the car and while I was driving I smelled a strong gasoline odor, and in about 3 miles the engine acted like it was running out of fuel, then died on a freeway off-ramp due to fuel exhaustion. A caltrans (or san jose) freeway safety car came by and put about 2 gallons of gas in my tank, but as soon as the engine started we both smelled raw gasoline. …”
