This concerns our 2016 Buick LaCrosse. We leased the car late in 2016 for 3-1/2 years, then purchased it including an extended warranty. Two problems occurred. First the fuel supply line to the engine began leaking, leaving a gasoline odor inside the car. We took the car to our dealership and had it repaired. We told the dealership we purchased an extended warranty with the car and were told this repair was not covered! We had to pay ?$471 out of pocket which we don't agree with. The second issue is the Return fuel supply line which let loose when starting the car, (weeks later) spraying gas all over the garage floor. I opened the hood to check the problem and tried starting the engine again. There was a small fire which I extinguished immediately. We had to have the car towed to the dealership to get it repaired a second time for fuel line issues. This time it cost us ?$978 out of pocket to get it fixed. They said again extended warranty did NOT cover this problem. I am told by a GM executive that GM has a separate warranty (10yr) for EPA fuel & emissions compliance that should have covered this situation, yet the dealer charged us for the repairs. I have also heard that NHTSA has a similar regulation which I would like to know more about.

My fuel line rubbed against a metal bracket in the car taking away the insulation. The only way I found out about this was because I changed the spark plugs on the car. I have asked Buick to replace the line however they refused because of how many miles I have on the car.
