The National Highway and Traffic Safety Administration has upgraded its fire-related investigation on the Chevrolet TrailBlazer. The investigation, which has been extended to a full engineering analysis status, now covers 342,000 model year 2006-2007 TrailBlazers.
So far, the NHTSA and GM have received 242 complaints, including 28 fires but no injuries. Some of the fires occurred while the vehicle was in motion but others happened while it was off and unattended. For its part, GM is instructing any TrailBlazer owner who smells smoke or whose power windows stop working to contact their dealer.
The NHTSA will examine other GM vehicles using the same GMT360 platform, including the GMC Envoy, Buick Rainier, and Saab 9-7X, but GM has previously stated that those vehicle have different door configurations. The GMT360-based TrailBlazer was discontinued in 2009, but a new and mechanically unrelated model is undergoing a global launch as of this writing. A U.S. launch of the all-new model hasn’t’ yet been announced.Google+
