G.M. sent notices to costumers in June 2003 of possible engine cylinder problems in early 2002 Chevrolet Trailblazers. This pboblem is quite serious and has in the pistons, develop a knock or slap.this can and does cause damage to cyl. Walls and other internal parts. G.M.has offered to replace pistons only.this is not what should be done in a vehicle with only 17,700 miles.itis my feeling the engine should be replaced.G.M. does not.I have spoken to Chevrolet customer and was told only pistons would be replaced.this would involve nearly if not completly rebuilding the engine.this is not acceptable to me as I belive I an intitled to have the engine of a new vehicle not a rebuilt engine acceptable for an aged vehicle.

Problems with air bag dash light, fast engine idle, air conditioner, rear hatch inner strap broke, etc... the airbag light was intermittent. The sir module was replaced, and there was poor terminal connection at the sir wiring harness, and was traced/repaired on the left side impact connector and the codes were cleared. The engine idled fast(especially at start up, and the fuel mileage was 13 mpg. The results of the evaluation and repairs were: Passenger impact connector was loose(repositioned/connected), idle within specifics, the emblem had fallen off, the rear hatch inner strap had broken, the transmission seemed to take long to shift into gear(happened sometimes when cold), and the PCM needed to be reprogrammed(J6355 power train controller PCM). There was a thumping sound in the rear differential when shifted, the A/C would blow out cold air when the A/C indicator was off, hot air would come out of the defroster area on the dash when the indicator was set for heater on the floor, the engine made a tapping sound, the lift gate weather strip had come apart, and the battery kept losing charge(3 occurrences).

Engine stall - truck stalled and all lighting and components went dead while slow to stop at an intersection. The truck could not be re-started. After 10 minutes, the truck started again and was able to drive on. Subsequent attempts to start the truck failed resulting in it being towed to the dealer. The dealer had to replace one of the computers in the truck and it has been fine ever since. I heard about the investigation for the Envoy and Bravada but not the Trailblazer. My truck is a Trailblazer and did experience the same problems as the two sister trucks that share the same mechanicals.
