Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Vehicle started leaking fuel underneath at the nylon fuel line. I had it repaired and it started leaking in a different location. Apparently the entire line is faulty and I cannot even seem to find a replacement. Fire hazard!”
NHTSA complaint #11140192, filed 2018-10, 89,000 miles“My 1991 Cadillac Deville has had a problem (as had the 1985 Cadillac) with sudden acceleration/engine racing. This is most noticeable when the car is stopped at a signal or stop sign. Though my foot will be firmly on the brake pedal, the car engine races and then the car lurches forward. My solution? I keep a good distance behind the car in front of me to prevent the lurching into the car in front. I am concerned that this will at some point cause an accident, whether it is parking the car or when the foot is off the brake momentarily or when the foot is on the gas pedal. …”
NHTSA complaint #10316438, filed 2010-03, 105,000 miles“When vehicle has about 7 gallons of gas, and when making a hard right turn or going up hills, vehicle will shut off completely. Contacted dealer, and dealer noted that intake valve in tank was not registering that there was fuel.”
NHTSA complaint #8001824, filed 2002-01“Fuel line connector lock retainer disconnected from inadvertent release. Without retainer the fuel line will disconnect when the device is rotated 1/8 turn in either direction. One of the retainers was missing, and filter specified for vehicle did not fit.”
