Transmission cooler lines between the radiator and transmission are corroded and pitted. The lines are installed over the exhaust catalytic converter. There is transmission fluid leaking from the lines, which is dripping onto hot exhaust components and burning, creating a fire hazard. These lines appear to be stainless steel, which shouldn't be corroding. The lines should not be in such close proximity to exhaust components. When the vehicle is not running/in motion, transmission fluid pools on the ground under the vehicle. In motion, the fluid is being blown rearward, coating the undercarriage and exhaust.

My 2001 chevy blazer changes from 2wh to 4 wheel drive automatically while the vehicle is moving. This isn't the first time this has happened. I was able to get my car off of the road safely and change it back into 2wh, but it kept switching back into 4 wheel drive. There is evidently a defect.

Front wheel bearings had to be replaced for a second time. The car has only 60,000 miles on it! The second time, the bearings were no longer covered under warranty and I incurred over $1000 in repair costs.

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?

My wife and I bought our '01 chevy blazer used in 04/05. From the start we had a hard time getting it to engage/disengage 4wd. This last winter my wife, the primary driver, complained that the vehicle had no power while coming home one night and the weeknights following for a week. I checked in the mornings it was fine. Pretty soon we both started noticing the gas gauge bouncing around like it was dancing. My wife thinking she was running out of gas would pull into the first gas station. She would fill up and leave the station only to have it happen again after pulling away from the pump. One month later, her and our 3 small children got stranded when they went in to convenience store. A minute later the blazer had died and the key in the on position. Replaced the fuel filter and then the fuel pump ($350 just for the pump!!!) the heating element in the pump had fried it. 04/06 the ABS failed and she almost hit a pedestrian. 2 weeks later we start hearing this popping noise when slowing/stopping and accelerating. 05/06 the battery died on her with no warning. Tried jumping it and it wouldn't hold a charge. Got that replaced. Then in 08/06 we didn't drive it because the plates had expired and we couldn't afford to replace them yet. Finally I drove it on 08/13/06 for 1 mle to the store and on my way back while stopping at the stop sign 2 blks from my house, I heard this loud clunk noise and then the vehicle started whinning. Now the thing won't move. It starts and whines, but won't move. Transmission is shot and is going to cost $1600 to replace with me doing the work. And so now, like 90% of the country, I am making a very high car payment except mine is on a car that I can not drive. This and other web sites about vehicle recalls prove that there are some serious issues with these vehicles and nothing is being done about it. What needs to happen is for some one to die b/c of these defects and then u will be scrambling to correct the problems. This is ridiculous.

My friends borrowed my vehicle, a 2001 chevy blazer, and went camping in the mountains. The vehicle was parked at a location that could have been very dangerous due to this failure, it was near a creek bank with a drop of approximately 30 feet. When the vehicle was started and put into reverse all it would do is coast forward which could have been very dangerous if they did not react in time as it could have went over a cliff. Fortunately they were in an area where there was a pay phone. They were staying at a state park and there are many areas that are very remote and are several miles away from phones or people. I was advised by aamco transmission that they see this transmission problem on a regular basis and it is caused because the reaction sun shell was made of an inferior metal and even in repair technical bulletins it specifies to repair problem by replacing with a "more robust heat treated reaction sun shell". When this occurs, it also affects second and fourth gears. In order to repair this problem the transmission needed completely rebuilt at a price of $2,326.38 plus a towing bill.

It would switch from 2 wheel drive to 4 wheel drive while driving ,causing car to slow down dramatically. Transfer case actuator module bad on truck when called for warranty they stated it was a common failure. I felt it was a deadly and dangerous situation, depending on where you were driving when it happens, and should be looked into.
