2005 Chevrolet Trailblazer 360

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.

The Office of Defects Investigation has received 668 complaints alleging inaccurate fuel gauge reading while driving in model year 2005-07 Chevrolet Trailblazer, GMC Envoy, Buick Rainier, and Saab 9-7x vehicles.Of the 668 complaints, 58 incidents were alleged to result in a vehicle stall.Of the 58 stalling incidents, 43 complaints reported stalling because the fuel level reading indicated more fuel availability than what is actually in the fuel tank. One complaint alleged a vehicle crash after the vehicle stalled while exiting the interstate, became disabled, and was struck from behind.Summarily, the complaints show an apparent increasing trend, with most complaints received within the past year.A Preliminary Evaluation has been opened to assess the scope, frequency and potential safety consequences associated with the alleged defect.
