Fuel line heat shield rusted and is leaking gas. I noticed gas outside before getting into car few days before gas leak was noticeable. I could not tell if it was my car or not as it was always in a parking lot that I noticed smelling gas. Yesterday, I noticed I had to pump the gas a couple times in order to start car. Went to the grocery store, and when leaving store, gas oder was strong. Once I was on my way home, 5 miles from store. Gas smell was strong inside cabin, and once home gas continued to leak for another 5-10 minutes after turning car off. I inspected the the leak this morning, and could see the heat shield on fuel line was rusted through along the underside of fuel line u joint. I am waiting for my car to be inspected by Fire Departmnet so that I can have to towed (Nebraska requirement to towe car with gas leaking issue) to repair shop.
I purchased this vehicle used in December 2014, the very first night driving it home, the engine would nit start. I immediately called the dealer, took the car back and watched as they ran a diagnostic. Nothing was wrong with it. I did some research and it seems to be a normal issue with the make and model. Then I noticed the faulty gas guage, reading low fuel then all of a sudden I have gas. Again, contacted the dealer, took it back and yet again, diagnostic ran with clear readings. I looked up thaylt issue and of course, complaints about the same issue were common. Finally, on April 9th I was on my way home and was involved in an accident. It was a front impact accident which totaled the vehicle. The air bags failed to deploy. The windshield was completely shattered, glass flew everywhere. After the front impact, the vehicle rolled over then landed on on the passengers side. …
Tl* the contact owned a 2005 Buick Rendezvous. While driving at an unknown speed, the vehicle caught fire near the rear passenger side.

A police report was filed. The manufacturer was not made aware of the failure. The approximate failure mileage was 196,000.
Intermittent loss of power, loss of ABS brakes and loss of AWD. When you apply pressure to the gas pedal (accelerator) if you depress the pedal for what feels like over a 1/2 inch you lose power and the rpms go sky high and you can hear it trying to rev up. To get going you have to release the gas and press lightly. I loss power, ESP. Going uphill since it needs more to go, but you can't give it more gas else it won't go. I and my fianc were almost hit in an intersection because of this loss of power. You can gain speed, but very slowly and anytime you depress the gas pedal further it again fails. Replaced three wheel bearings, all brakes, two calipers and the throttle position sensor. Nothing shows on the readout except for the front bearings aren't reading right, but they're brand new and have been re-checked for defect. Still that hasn't fixed the issue. …
