  • Automatic transmission
  • 200 miles
Not long after I purchased my 2002 Blazer, I started noticing that at random times the motor would start racing when I started the engine. It ran very loud for a period of time and then would finally slow down. While driving the vehicle this would also happen. The rpms rapidly increase when accelerating, and it would make a loud roaring noise, but the vehicle doesn't go any faster. I took it in to the shop and was told this was normal, that it was the clutch fan. It is extremely hard to believe that this is normal for a new vehicle. I have had the Blazer since April of 2002 and it continues to do this and has sometimes put me in very unsafe positions. This problem seems to me to be more of a transmission problem than a fan. I have also had problems with the fuel gauge. It will show empty when it has plenty of gas. It has showed low on fuel, and then when I stop to get fuel, it will not take any gas. But then I have run out of gas right after trying to put some in the tank. The third problem is the left front door hinge. The pin continuously works out of position and it feels like the door is about to fall off and it doesn't close properly and I have to have the pin knocked back into position. Also, at the time I purchased the vehicle, it had a cassette player and the dealership agreed to install a cd player as part of the purchase agreement. The vehicle also had optional controls on the steering wheel. When they installed the cd player, the controls on the steering wheel no longer worked. When I asked them about this, they just said that this cd player could not be controlled from the steering wheel contols and left it at that. I think they should have installed one that could have functioned the same as the factory installed equipment.
