* - on two different occasions my 2004 Buick Rendezvous has caused the inside of the car to fill up with strong gasoline smell. When checking the ground I discovered it was leaking gasoline. I was told that there was no more recall on my VIN# - however, I'm discovering that other 2004 Buick rendezvouses are reporting the same of similar problem under campaign #07V349000. I was never notified of a recall for this issue, which could be a very serious safety issue, as I haul around by very young grandchildren. What? Does someone have to die before this issue is addressed properly?

No acceleration,when I go up a hill no acceleration, or when I go to get on the highway no acceleration, and very dangerous. I went to dealership for a diagnostic test and I replaced fuel tank pressure sensor and vent solenoid, no acceleration. I went to another dealership for diagnostic. They recommended that I replace 3 electrical harnesses and connectors $1350 dollars parts and labor too much for me and that May not solve my problem. I told them the problem was corrosion in the connectors to the fuel pump $160 dollars later they agreed with me. Still dangerous.

Engine stops working with loss of all control, battery turns over but vehicle will not start. After approximately 1/2 hour engine starts. Drove to mechanic and no information availoable in computer. All data removed.. Problem repeated at 70,00 miles 90,000 miles and at 150,000 miles. No mechanic could find any pronlem. First occurred when parking after a 50 mile drive. Next appeared at a stop light. Last apperared while slowing down at an intersection. Took vehicle off the road after the last incident. Feared for my life.

Recently the cabin is filling with the smell of gas fumes while at idle and filling at gas station. There is no service engine light coming on, indicating some sort of leak in the fuel entrance to the tank. There is a recall #06230 that directly relates to this, however I am told that my vehicle was made a little later and GM had determined the later produced vehicles did not have the problem that required the fuel tank to be replaced. I think this needs to be investigated further.

My grandson and I were shopping, then I filled my gas tank. We then went into the grocery store came out, smelled gas and looked under car. It is leaking gas, we hurried home--went from full tank to 1/4 full tank in 58 miles. It is sitting and not driven. And I have a 2003 Rendezvous that has a gas smell that is very strong but hasn't leaded out gas yet.
