NHTSA's summary

As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE11-014.

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.

What an NHTSA investigation is

NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.

An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
