Fuel lines fuel pump corrosion on 2002 GMC Envoys. . The vehicle is leaking an enormous amount of fuel while in motion. GMC has not honored this extended coverage because of a branded title. This is extremely dangerous.
I own a 2003 GMC Envoy XLT service engine light is on returned the vehicle to the dealer and was told this is a cracked fuel tank. Dealer showed me where the fuel was leaking it was leaking on a weld that attaches the filler hose to the fuel tank. This certainly isn't a wearable part and it doesn't receive much corrosion due to being a florida car. There are many forums on the internet and many vehicle owners that have the same problem. I would think that a fuel leak may lead to extremely hazardous situation for all motor vehicle owners. I understand an investigation has been raised and closed. It is unfair that gm manufactures a fuel tank that could be a risk to its consumers. This case needs to be revisited and reopened.
