2008 Buick LaCrosse fuel level sensor problem
I have a fuel gauge problem on my 2008 Buick LaCrosse. After a fill up, the fuel gauge goes to the full mark, and stays there. This has happened four times since Iíve owned the car, and each time the dealer replaces the fuel level sensor in the gas tank (still under warranty thank goodness) . The dealer has told me that the cause is sulfur in the gas causing the small wires in the sensor to corrode and break.
If this is the cause, I would expect that it would be fairly common problem and that by now GM would have redesigned the sensor to fix this issue. Therefore, I wonder if the dealer is fixing the symptom rather than the cause.
Has anyone else experienced this and/or can give me a hint as to what I can tell the dealer when I take the car back again next week for this so it gets fixed once and for all?
