Print this page Notes: The Trailblazer emerged from an "upscale trim line" of the Blazer, but there's nothing upscale about its transmission problems or its wonky, unpredictable headlights.

2002 Chevrolet Trailblazer Owner Comments

problem #3

Jan 182008

Trailblazer 4WD 6-cyl

  • Automatic transmission
  • 150,000 miles


The contact owns a 2002 Chevrolet Trailblazer. If the contact does not unhook the battery post each night, the vehicle will not start in the mornings. She purchased a new battery, but the failure persists. The front passenger side of the vehicle near the tire makes a roaring sound intermittently. Neither weather nor speed were factors. The contact believes that the gas tank is leaking fuel because it is burning more fuel. The vehicle was not taken to a Chevrolet dealer, but was taken to the dealer from where the vehicle was purchased. The mechanic stated that the vehicle was experiencing electrical failure and should be taken to the dealer. The contact was informed that the following NHTSA campaign id numbers did not apply to her VIN: 01V126000 (suspension:front:control arm:lower arm), 03V096000 (electrical system:wiring:interior/under dash), and 02V121000 (fuel system, gasoline:delivery:hoses, lines/piping, and fittings). The current mileage was 165,000 and failure mileage was 150,000.

Trailblazer 6-cyl

  • Automatic transmission
  • 53,907 miles
I have had my Trailblazer for 6 months (since 9-29-03). I bought it used and have taken it in to get things that have gone wrong with it checked. I bought the 3/36,000 warranty and have not benefited from it. I have read that there was recall on the front lower control arm brackets, which may fracture. I took it in because I was hearing a noise when I turned. They told me what the problem was and I drove it for another month while the parts were being ordered and the ok from GM to cover this repair. I have taken it in to solve the problem of the tail lights to keep burning out and failing. I have received many warnings from legal authorities and my response is that I did not know and have just gotten it fixed. I also have a problem with the engine dying while driving, idling, or accelerating. Dealership says that they are "trying to reproduce the situation" but cannot. I know that it happenned, just fix it. I have tried to trade it in, but owe too much still and I am very unhappy with GM and their approved dealership.
