Truck would only burn 12-14 gallons of diesel before gauge would read empty. Level sensor was the problem.

Sierra 2500

  • 30,000 miles
Check engine light comes on in mid June 2010...referred to owners manual which was possibly due to the exhaust filter...owners manual stated specifics to clear which it did. Light appeared again and repeated owners manual procedures then scheduled appt at dealership to look at in which we received washer fluid recall at same time. Dealership repaired recall but could not duplicate reason for the "maintenance required light" issue. About a week later truck became hard to start...glow plug indicator would not work and fuel began leaking from the fuel filter. Returned vehicle to dealership in which they found the fuel filter leaking and fuel sensor cracked in which they cannot find a replacement part and are doing a worldwide search. They also told us that our truck was not equipped with a glow plug indicator which we strongly advised that it was and verified with purchasing dealership. To date, the vehicle is still at the dealership and they have not been able to repair either issue. Advised that truck cannot be operated due to the fuel leakage.
