Noticed noise; have taken to dealers 8 times and they can not fine the cause of noise; now GM representive anthony teta says it is inherit design problem; rox covert told me he would fix it, replace it or give me my money back - pickup it up 5/20 and because it didn't make the sound returned to me. I do not want to put up with this noise, I'm tired of the run around, and very disappointed with my first new vehicle purchase that covert, Chevrolet or GMC will not try to right this problemed vehicle. Please help me if you can.

Blazer 4WD

Ever since I bought this vehicle I have had nothing but trouble with it. Since I have bought it in July it has been in the shop for approx. 10 times. The first day I brought it home it would not go into reverse. Needless to say it already has a new transmission. I have also had problems with the rear middle seat belt locking up and making it impossible to wear. I have brougt this problem up to the dealer several times and they have even replaced all of the seat belts, but it still persists. I have now been told that it is because of infant seats, however how can this vehicle be suited for five passengers when in reality it can only hold four. Another problem I have had with this vehicle is the heater blower failed to work. I brought my vehicle back to the shop and they replaced it. I have also had problems with the 4WD system switching between 2hi. The dealer has installed a new switch as well, so the problem has been solved. One of my newest concerns is randomly when I start the vehicle in the morning the engine revs up really loud. The loud noise gets even louder when you accelerate the vehicle. When bringing in this problem to the shop they said that it is the fan clutch and that it is normal. I find this hard to believe. People that hear the noise are in disbelief that a new vehicle can make such a noise. I also am having a concern with squeaky breaks in the front end. The shop states that semimetallic brakes will make some noise at times. In all of the cars I have owned I would have never thought that a 2002 would have squeaky brakes and that it would be normal and unable to fix. I am very concerned about this vehicle and I question how reliable and safe we are driving it. GM will not help me in replacing this vehicle so I guess my next step is the attorney general.

While driving my trailblazer the engine failed as I was stoping for a red light. Luckily there were no cars near me and I was able to safely bring the car to a stop and force it to the curb. After about 15 minutes I was able to re-start the engine and I drove it to the dealership. They inspected the car, called Chevrolet with their diagnosis and were immeadiately informed by Chevrolet to the amazment of the serivce manager at the dealership that a new engine was needed. It seems they knew that a new engine was needed so quickly as this is a major problem. A search on your web site and the trailblazer forum at shows that this is a wide spread problem. It is apparent that GM has knowingly placed "defective" engines in the 2002 trailblazer. What would have happended if my engine failed on the highway going 70 miles an hour? the NHTSA must address this situation before people die from this. This has all the makings of another Ford pinto fiasco.
