Two problems related to tail light have been reported for the 2004 Chevrolet Trailblazer. The most recently reported issues are listed below.
The contact owns a 2004 Chevrolet Trailblazer. While at a stop, the contact noticed that the tail lights failed to illuminate. In addition, when the key was turned to the off position, the vehicle remained on. The vehicle was taken to a dealer. The technician diagnosed that both tail light strips needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failures. The failure mileage was 163,000.
I have replaced the light bulbs on the back of my car 3 times and asked the agency to replace the whole part or casing after I found a recall that the taillights were defective. I informed Chevrolet of where I found the recalls , I was told this website is only opinions from other people that don't know what they are talking about. I was told in the agency that the problem was only on 2003 models and not 2004's. The agency said they would replace the whole part anyways but the next day a police officer almost gave me a ticket because he said I failed to indicate I was going to make a left hand turn on a one lane road. I've taken my car to the agency twice for that problem and obviously they haven't replace the part. My car is less than two years old and it has given me problems beyond that one.
