Example complaints

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

“My 1999 Gmc Sonoma has had a faulty fuel gauge since the vehicle was purchased. It was taken into jim causley's pontiac/Gmc in clinton township mi once for warranty repairs but the problem was never fixed. Service rep informed me that it was caused by a bad vehicle ground. Problem still persists to this day. The only way I can avoid running out of gas is to reset the trip odometer every time I fill-up.”

NHTSA complaint #10398309, filed 2011-04, 8,000 miles

“Fuel gauge is inaccurate and fluctuates when truck is in park or neutral reads between 3/4 and full when driving even if tank is close to empty. Drops to show tank is empty when in park even if full.”

NHTSA complaint #10093789, filed 2004-10, 67,000 miles
