The fuel gauge indicates properly until it reaches the halfway mark. It then fluctuates and is not reliable. This could lead to running out of fuel in traffic, in-climate conditions or in isolated areas without indication. This is a safety hazard that seems to be prevalent on these vehicles and needs to be addressed!

Car windows and gas gauge haven't worked in a long time however now the car will not start consistently even with a brand new battery. You have to charge the battery every time to start it. Ready to get rid of this worry.

The fuel gauge does not read correctly. It will bounce from 1/4 a tank to 1/2 a tank to full. It is always all over the place. This is a sign of a bad fuel sending unit (its a sensor). There needs to be a recall for this, so I know how much gas I have in the car, I can't keep dumping $10/$20 a week.

Tl* the contact owns a 2000 buick lesabre. The contact stated that since purchasing the vehicle, he noticed that the fuel gauge would provide an inaccurate indication of how much fuel was actually in the tank. The failure recurred frequently and would show that the fuel tank was empty when it was not and it would display full when the fuel tank was actually empty. The vehicle was taken to an authorized dealer who stated that the instrument panel needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The current mileage was approximately 116,000 and the failure mileage was approximately 16,000.

I have a 2000 buick lesabre with 52000 miles on it. When the fuel gauge drops below 1/2 tank it starts moving erratically. It will move up to full and then drop down to 1/4 tank, just moves back and forth so below 1/2 tank I don't know how much fuel I have. It also confuses the fuel system computer in the driver information center so that is not reliable either. I just have to keep track of my mileage and based on fuel economy I determine when I need to buy gas. I can't find any recall information for the 2000 model but read some where that a later year model had this same problem and the only fix is to replace the fuel tank where the sensor is located. This is not only faulty engineering it is incompetent engineering.
