Investigation of Fuel Level Gauge System Failure

Subject: Fuel level gauge system failure
Components covered:
  • Fuel system
  • Fuel gauge system
Investigations Summary: This investigation was opened on Apr. 25, 2011. It was closed on Sep. 23, 2011. The office of defects investigations (odi) analyzed complaint data provided by general motors (gm) as well as complaints submitted to odi from consumers. In total, there were 5,089 unique reports indicating an inaccurate fuel level reading while driving. General motors stated that this condition occurs when the contacts of the fuel sensor wear prematurely. Most of the complaints indicated an empty fuel gauge reading after filling the tank. Less than 10 percent of theodi complaints involved an engine stall incident. During this investigation, gm developed a remedy procedure and issued special coverage bulletin instructing dealers to install a new design fuel level sensor. The bulletin was sent to dealers on August 10, 2011 and the owner letter mailing began on August 15, 2011. See the investigative file for copies of gm's bulletin and owner letter. This preliminary evaluation is closed.
