Feds Ramp Up Investigation of Engine Fires in GM SUVs and Pickups

WASHINGTON The National Highway Traffic Safety Administration, which had been checking into reports of engine fires in General Motors full-size SUVs and pickups since early this year, said recently that it has upgraded the effort to an "engineering analysis" in an estimated 2.7 million vehicles. The investigation, which has not reached the recall stage, includes all of GM's full-size pickups and SUVs from model years 2007-'08 as well as 2006-'08 Hummer vehicles.
NHTSA spells out that the engineering analysis covers the automaker's GMT900 vehicles, including the 2007 Chevrolet Tahoe, the 2007 GMC Yukon and the 2007 GMC Sierra 1500.
NHTSA said the move will help to further "assess the scope, frequency, origin and cause of the alleged non-crash-related engine compartment fires in the subject vehicles," in its defects investigations summary of the problem. The federal watchdog said GM has provided it with "41 allegations of non-crash engine compartment fires, including 16 allegations of fires originating with the ignition in the Off position." Eight of the 41 fire allegations also allege property damage as a result of the fire, NHTSA says.
No fatalities have been linked to the problem.
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."
