Feds Investigating Engine Fires in GM Trucks, SUVs

Posted: June 19, 2008

Autoblog reports, "Way back in February, the NHTSA began investigating certain full-size trucks and SUVs from General Motors for the possibility of their engines spontaneously combusting, even when the ignition key is in the 'off' position. At that time, the investigation covered some 423,000 vehicles, and GM seemed pretty confident that the issue would not be widespread. Yeah, it appears as if the General was a little off in that assessment. The engine fire issue may now affect about 2.7 million vehicles, including all of the latest Chevrolet, GMC and HUMMER full-size models."

Consumer Affairs explains, "Investigators are examining the electrical system, engine and engine cooling system; battery cables; under-hood wiring, fuses and circuit breakers."  While the investigation has not yet triggered a massive recall of GM SUVs, NHTSA sources "are now call the probe an 'engineering analysis' which could eventually lead to a recall."

The list of affected vehicles includes most models of large GM SUVs or full-size trucks manufactured since 2006, including the Chevy Silverado, Tahoe and Suburban, Hummer H2, GMC Sierra, and Cadillac Escalade.  We should also note that the list of affected models has expanded since the investigation began, and it may not be done growing.
