1 Tank Assembly problem

Failure Date: 02/29/2012

On 2/29/12 I came back from the grocery store and parked my vehicle and unloaded my groceries and returned to my vehicle which was left running. I put my vehicle in drive and proceeded to do a uturn and had put the vehicle in reverse to prevent collision with other vehicles parked on the odd side of the street. When I put the vehicle in reverse the car just stalled, it did not move at all. I looked at the dashboard and it keep informing me that the fuel was low. This was impossible due to the fact I knew I had over a half tank of gas in my vehicle. I had to put the vehicle in park and re-start the car to continue parking the vehicle. I live on a very busy street and luckily there was no traffic coming when my car stalled. The incident occurred again on 3/4/12 when I went to start my vehicle and the dash indicated that the fuel was low but this time the gas gauge proceeded to beep and the orange low fuel indication light came on and the gas gauge needle began to move to e and then the car stalled once again and I was unable to move the vehicle.

2 Tank Assembly problem

Failure Date: 01/02/2011

No gas guage, it reads empty even when the tank is full. Low fuel light is constantly on, and when I am truly getting low on fuel, it may bounce to an area between e and 1/4 tank mark. I am having to pay attention to the miles I drive and hope that the mpg at 15. 9 is accurate since nothing else seems to be.

3 Tank Assembly problem

Failure Date: 10/10/2010

We filled up the SUV and the gas gauge did not register that the tank was full. After a while the gauge slowly moved up and showed that the tank was full. After a couple of weeks of that, the gauge now does not move off of empty at all. Often times the gas reminder signal goes off letting us know that the tank is empty, however we had just filled up the tank.

4 Tank Assembly problem

Failure Date: 03/19/2010

Tl- the contact owns a 2005 Buick Rainier. The contact stated the fuel gauge on the vehicle does not read properly. The contact stated that even if they fill the gas tank, the gauge will read empty or half fuel. The contact took the vehicle in for an oil change and was told there was an investigation into the fuel gauge, but the contact was not told what caused the failure. The failure mileage was 60,000 and the current mileage was 85,000. Rl.

5 Tank Assembly problem

Failure Date: 02/03/2010

Having difficulty with driving vehicle. Seemed to be over road. Several evaluations at car dealership, different fixes without resolutions. Finally the air system which regulates the balance, height etc stopped functionally. The car sits low to the ground. I first started complaining of unusual noises from the speakers of the car. Approximately 9 months ago. Dealership did not know what that could be. Now I am told the compressor and the shock system is gone. The cost to fix is 3000. 00 I have found a company who has an adaptive kit with conversion to standard shock system. This company tells me that they are sedmomg 15 to 20 of these kits out a week. GMC does not offer any options. My concern is this has been a problem for multiple months without the dealerships ability to find the problem in a timely manner. The car was rendered unsafe to drive because it was hard to steer and difficult to keep in your own lane. Additionally, the gas gage has gone bade, approximately 50,000, the first Rainier I had there was a problem with getting the fuel into the tank. Traded the 2004 for 2005 because of this problem. Now this gas tank the gauge is defective.

6 Tank Assembly problem

Failure Date: 01/23/2009

Fuel gauge reading incorrect. Dealer replaced sensor and had to drain/remove gas tank to replace. While this was still under warranty (55,000 miles, I would have had to pay approximately $550.
