Example complaints

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

“I was driving down the road when the 'check engine' light came on. I took it to the dealer to see what the issue was and they stated it was a leak in the gas cap and that I didn't have cap tight enough. On the way home from the dealer the 'check engine' light came back on, so I took it back to the dealer. They stated that the fuel filler neck needed to be replaced and it's not covered under warranty.”

“Fuel tank filler was giving as the reason of my trucks problem before it was looked at by a technician. I was told that this was a common problem with these trucks. The fault would cause the emissions system to fail and therefore would also be a hazard because it could cause a fire at the time the truck was being filled or from escaping vapors. The part was (is) being replaced and is costly to the consumer.”
