Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Rainier 6-cyl

Fuel gauge acts erratic. Shows 3/4 full, then slowly drops to empty with low fuel alarm sounding. I know there is fuel in the vehicle. Fuel sensing unit is malfunction.

  • 63,000 miles
The contact owns a 2007 Buick Rainier. The contact stated that the fuel gauge was providing inaccurate fuel level readings and would read that the tank was empty when it was actually full to capacity. When the tank was empty, the fuel gauge would read that the tank was full. The dealer informed the contact that her warranty would not cover the cost to repair this particular failure. The manufacturer advised the contact that they would only be willing to cover fifty percent of the repair costs. The contact was awaiting repairs. The current mileage was 64,000 and the approximate failure mileage was 63,000. The VIN was unavailable.

Fuel gauge will drop to empty and the low fuel light will come on, the driver information center will sound an audible alert and will show low fuel indicator. When you have a full tank of gas it will show a full tank and stay there until you use about 1/8th of a tank and then the fuel gauge start malfunctioning. Some times the fuel gauge will show full and some times it will show empty and all the bells and whistles will activate. I took it to the dealer where I bought the vehicle and they told me GM was aware of the problem and that GM would pay 1/2 of the repair costs which are about $145 and the vehicle owner would pay the other 1/2 of the costs. It would take about 2 hours to repair. This is a known problem by GM.

When fuel tank is filled to full, fuel gauge reads empty and low fuel warning appears on driver information center. Fuel gauge starts to indicate fuel level when fuel tank is about 1/2 full. Fuel level indication is very inaccurate when fuel level approaches 1/8 tank. Very easy to run out of gas.

My wife was stranded with no gas even though the gas gauge said 1/2 full - took to dealer and they said sender unit was bad, they said it was all too common on this vehicle.

The vehicle fuel gauge is erratic and inaccurate! when the tank is filled it shows empty and displays a low fuel level warning. As the tank draws fuel it fluctuates between full and empty. At one point it would stabilize at a certain level but nowadays it either shows full or empty. I track mileage and fuel use but would not trust the vehicle for safety concerns with other family members since there is no sure fire way to know if/when the vehicle will run out of fuel! I only let them use it when I know it is full and they are only making short local trips.

  • 51,000 miles
The contact owns a 2007 Buick Rainier. The contact stated that while driving 50 mph, the vehicle stalled without warning because the fuel level gauge displayed that the fuel tank was full when in fact it was empty. In addition, the gauge would read that the tank was empty when it was full to capacity. The dealer was contacted and they advised him that there were no recalls for the failure. The vehicle was not repaired. The failure mileage was approximately 51,000. The VIN was unavailable.
