GRAND JUNCTION, Colo (KKCO) Many makes and models are included in the recall, but the 2006 and 2007 Chevrolet Trailblazer was the biggest seller out of all the vehicles involved. Here's the problem; the power windows and the door lock switches in the SUV's could short circuit and start a fire. Dealers will fix the problem for free. Owners will get letters telling them when to schedule an appointment. Other vehicles included the GMC Envoy, Buick Rainier, Isuzu Ascender, and the Saab 97X. All makes and models are years 2006 and 2007.
