In owners' own words
Fuel gauge is intermittent, registers low or high at different times when tank is known to be full or near empty. Cannot be depended on to give accurate information. Registers higher than actual at times, lower than actual at times. Several times before discovery of the problem we have been at risk of low fuel levels that were discovered when refueling. Intermittently continues. Fuel system, gasoline · reported at 83,500 miles
Erratic fuel gauge beginning in aug, 2010. Always fails after complete fillup. Sometimes operates below 3/4 tank. Currently not operating at all for past 90 days. It is showing "low-fuel" warning light irreguardless of the amount of fuel in the tank, the gauge needle remains on empty. There is no way to know how much fuel I have or when my 2006 Buick Rainier will run out of fuel. Fuel system, gasoline · reported at 58,000 miles
On few occasions I run out of fuel because the defective fuel sensor unit in the fuel tank. One time it happened on the busy highway. This defect can lead to very dangers situation. The fuel indicator becomes erratic and unreliable without any warning. There are a lot of complains on the internet about fuel sensor in gm suv's. Same part is used in all gm models (2005-2007).
