There was a strong smell of gas in the car as well as another vehicle who pulled me over to tell me my truck was pouring gas. After having it towed to my mechanic, he informed me that the fuel pumped assembly had rotted and need to be replaced. He stated that this part should not have rotted like this. Thankfully this was found before anything catastrophic had happened as I constantly driving around with my two young children in the car. I have kept the old part to show how it had rotted. I haven't heard of any recall for this but being that this situation was extremely dangerous I feel it warrants looking into. This was also an expensive fix and considering it should not have rotted like this, I feel I should receive reimbursement from the manufacturer. This is a huge health and safety issue that requires serious attention.
2005 faulty GMC Yukon dash system. Dealer originally told me it was the fuel pump but suggested it might be alcohol in the gasoline. I tried using ethanol free gas and it worked. I couldn't find any ethanol free gas on Dec 25th so I had to use 10% ethanol and my entire dash has quit working. I can't tell how fast I'm going, if I have fuel or how many miles I have on my vehicle. The GMC dealership wants me to replace my fuel pump, dash board and they estimate it will cost around $1500. It worked fine without ethanol!.
