Fuel gage not working properly. When needle gets between half and a quarter, it bounces back and forth from empty to full. Then at a quarter full, it goes to empty and stays there. You are never sure how much gas you really have and can cause the vehicle to stop suddenly.happens when in motion and still on all roads.

While driving home my fuel gauge stopped working. When I got home I turned the car off and then back on and the fuel gauge was now in the 6 position on a clock. Now I have no idea if there is any fuel in the car or not. Luckily I reset the trip meter with every fuel up so I know I can go approximately 300 miles. Although in the winter when we have to idle our car so the fuel mileage goes down and I do not get as many miles on a tank. Hope I don't run out of fuel during the winter. In reading online reviews about this issue it turns out it can get worse and cause the speedometer to stop working. Then I may be speeding and not even know it. I did try and have it fixed but the guy charged me $207 and it did not fix the problem. At the local gm dealership they said they would repair it for $350.

I've owned 5 buick lesabres, and continue to run two of them (2002 lesabre with about 180,000 miles, and 2004 lesabre with over 80,000 miles VIN: [xxx] for the 2004, and [xxx] for the 2002). Both currently owned lesabres have fuel gauge problems. My 2002 showed erratic inaccurate readings, but now is flatlined at empty, even if the tank has just been filled. My 2004 is showing the opposite reaction, showing full, even after a full trip should be sending it toward an empty reading. Something similar happened on a previous lesabre I owned, and cost me a new fuel pump & gauge running nearly $500. This is obviously a common occurrence if I've had it occur on 3 of five lesabres I've owned. It's also a very common complaint on the internet. Just recently on the 2002, I ran out of gas in the middle of heavy traffic due to gas gauge inaccuracy. Fortunately it was a low speed region. However, had I run out of gas in rush hour traffic surrounded by 18 wheelers, this could have lead to traumatic injury or death. 1 failure ... I could tolerate, and was willing to pay for it without complaint ..... But 3 out of 5 lesabres !!!???? That's a design defect or manufacturing defect. I am seeking a recall on buick lesabre gas gauge units information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
