One problem related to radio/tape cd player has been reported for the 2007 Chevrolet Trailblazer. The most recently reported issues are listed below.
My husband was driving about 40 mph on a country paved road when his side airbags went off. His radio and lights started flashing. He was able to get home the mile or so, parked the car and shut it off. When he went to start it the next day nothing worked. He was startled by this happening and was lucky he didn't cause an accident or get hurt. He could have caused an accident very easily due to the visibility. Not sure what caused this to happen. - unknown the vehicle was taken to a chevy dealer but they were not able to diagnosis it so at this point we are not aware of exactly all that was effected with the vehicle. I have attached the denial from our insurance.
