Since I bought my 2001 chevy blazer, I've had to replace ball joints everytime I have a front end alignment. This year I've replaced 3 wheel bearings, fuel pump, and I just lost my transmission. I've had the light recall fixed. My service engine light stays on, but you cannot put a computer to it because it doesn't work. My ABS light comes and goes. Whats next?

Dt: the contact stated the check engine light came and the engine started missing. The air reflector on the bottom of the throttle bottle plate disintegrated; the air reflector has gone through the motor. The plate was embedded in the pistons, broke two spark plugs, and bent push rods. He changed the spark plugs. He then pulled the vehicle in and realized the push rods and lifters were bad. He contacted the dealer they offered no free remedy.

Dt: the consumer owns two gmc vehicles with the same problem. The consumer received nets recall 05v155000 on one of the vehicles but not for the other. The problem was with the fuel module reservoir assembly. Since the VIN was not included they would not correct the problem. *ak (12/02/05) the service engine light soon stayed on and the fuel gauge did not work properly.

On feb 4th, 2004 the service engine light came on so I took the blazer to the dealership(bert greenwald) to find out what was going on. I was told that the "air line & valve air pump assembly needed to be replaced. It's now may 4th, 2004 and I am still waiting for the part to come in. Each time I inquire about it, I am told that general motors doesnt want them to order the part until they come up with a plan to deal with this problem since it seems to be occurring very frequently. I feel that 3 months is to long to be waiting for feedback on this even though the dealership has said they not charging me to replace the part.

The theft-deterrent alarm goes off for no reason when parked and locked up. The oil pressure gauge moves eratically, dome lights and floor lights come on by themself and sometime stay on for a long time and sometime consistantly flash off and on, radio shuts off when turn engine off(not suppose to), and check engine light came on for a few days then just went off. The dealer replaced the bcm #9385236 but vehicle is still not fixed after several visits back to dealer.
