Chevy Trailblazer Door-Fire Investigation Upgraded by NHTSA

Chevy Trailblazer Door-Fire Investigation Upgraded by NHTSA

A defect investigation was announced in early February into reports of door fires in 2006-2007 Chevy Trailblazers, and now the investigation is being upgraded to an engineering analysis by NHTSA.

The issue is a malfunctioning driver side power master switch, which has reportedly caused 28 Trailblazers to catch fire, some of which were keyed off and unattended at the time of ignition. General Motors has received 167 reports and 698 warranty claims that allege the driver door module has melted and burned, while NHTSA has received 66 claims of melting and burning doors.

Other vehicles that ride on the same platform are now being included in the investigation as well, namely the Oldsmobile Bravada and GMC Envoy.

General Motors does acknowledge the defect, but whether it will result in a recall remains to be seen. “In exceptionally rare circumstances, heating could continue until the plastic ignites,” said a GM spokesperson in a letter to NHTSA.
