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.
The contact owns a 2000 Buick Lesabre. While driving approximately 40-50 mph, the contact observed that the fuel gauge had begun fluctuating between fuel level readings.
