Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“In june 2012 the car did not pass inspection and we were told we needed a new gas cap. We got a gas cap and it passed inspection. Since then we have had a strong fuel smell when the gas tank is filled completely. If we only fill the gas tank about 3/4 or less, there is no gas smell. We recently had the car serviced and the mechanic told us the gas cap needed to be replaced and a seal/cap in an overfill tank under the rear seat was loose. We replaced the gas cap again and the cap to the overfill tank was tightened. …”
