Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Fuel gauge reading inaccurate. With a full tank when starting and fuel level gauge slowing showing empty knowing I have just filled the tank. The level fluctuates up and down creating frustration and anxiety. My wife is now afraid to drive the vehicle. This has brought much apprehension while driving thinking there is a leak in the system.”

NHTSA complaint #10421480, filed 2011-08, 52,345 miles

“The vehicle fuel gauge is erratic and inaccurate! When the tank is filled it shows empty and displays a low fuel level warning. As the tank draws fuel it fluctuates between full and empty. At one point it would stabilize at a certain level but nowadays it either shows full or empty. I track mileage and fuel use but would not trust the vehicle for safety concerns with other family members since there is no sure fire way to know if/when the vehicle will run out of fuel! I only let them use it when I know it is full and they are only making short local trips.”

NHTSA complaint #10400291, filed 2011-05, 60,000 miles

“When fuel tank is filled to full, fuel gauge reads empty and low fuel warning appears on driver information center. Fuel gauge starts to indicate fuel level when fuel tank is about 1/2 full. Fuel level indication is very inaccurate when fuel level approaches 1/8 tank. Very easy to run out of gas.”

NHTSA complaint #10424032, filed 2011-09, 54,000 miles

“Fuel gauge will drop to empty and the low fuel light will come on, the driver information center will sound an audible alert and will show low fuel indicator. When you have a full tank of gas it will show a full tank and stay there until you use about 1/8th of a tank and then the fuel gauge start malfunctioning. Some times the fuel gauge will show full and some times it will show empty and all the bells and whistles will activate. …”

NHTSA complaint #10430509, filed 2011-10, 51,324 miles

“My wife was stranded with no gas even though the gas gauge said 1/2 full - took to dealer and they said sender unit was bad, they said it was all too common on this vehicle.”
