One problem related to seat broken has been reported for the 2002 Chevrolet Trailblazer. The most recently reported issues are listed below.
Driving down the road and had to stop suddenly. When the seat broke and went to the floor on one side. Pulled over and investigated and the weld on the arm of the seat control was improperly welded. The weld on the arm its self was half on the plate and popped loose. If had been going around a curve when the seat broke would probably caused a wreck. Going to have to buy a new seat and trade the vehicle off possibly. Afraid more welds could be missing or not done properly.
