NHTSA investigating 2.7 million GM vehicles over engine fires

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.

A preliminary examination of the electric systems throughout these vehicles is being conducted at this time. Depending on the results of the NHTSA's 'Engineering Analysis', a recall could follow. So far, there exists 41 reported cases of non-crash-related underhood fires, with 16 of those supposedly with the ignition turned off. Check after the jump for a complete list of all the possibly affected vehicles.
