Five problems related to transmission noise have been reported for the 2001 Chevrolet Blazer. The most recently reported issues are listed below.
Loud clanking noise heard under normal driving conditions. Transmission failed, no reverse and no 3rd or 4th gear. Vehicle has only 53,500 miles.
Consumer heard a noise in the front of vehicle. Consumer stated he had been hearing it a little, but currently the noise became more pronounced. Consumer had already replaced the transmission once. The consumer had to fill the tires every week. The tires leaked air since purchase. The tire service dealer suggested that there was no leak and that corrosion built up on the wheels in which air escaped through the rim of tires. There was a thumping noise in the front end and seems like it happens worst on right turns, the left wheel bearing was loose in the hub bearing assembly, the hood hinges rattling excessive clearence, there was excessive slippage and the clutch burnt. (laredo tires).
Transmission dropped out @44000 miles. 12/02 had to replace both front ball joints. Summer of '03 started making loud popping noises which came from front right area, it would pull unexpectedly to either side - mainly to the right and service 4wd light would come on. 10/03 had to have right front wheel bearing replaced. Could find nothing wrong with 4wd-don't know why light keeps coming on. Now 01/04, right front wheel bearing needs replaced again. I'm told part under warranty as long as I own vehicle cause gm has received so many complaints. What is gm doing to correct the root cause of this? I see I am not the only one with this problem. Thank god I have not had any accidents, but have had a few near misses because the it would "jerk instantly" and it caught me off guard. Does an accident / injury / fatality have to happen before corrective action is taken?.
Driving within the city I heard a clack noise and a loud noise came from the transmission, after that I couldn't use the reverse, and first gear was longer than usual, this vehicle only has 42,000 miles. I have spoken with mechanics and friends and this is a manufacturer failure with this type of vehicle, my mechanic. Told me he has to fix so far about one of those brand vehicle per month, a friend told me he purchased a chevy Blazer and moving it from dealer he couldn't move vehicle, transmission was locked, I need the manufacturer fix my car immediately at no cost. Since I purchased vehicle took it twice because I was hearing a noise, but Chevrolet dealer said everything was fine, they couldn't fine any noise, but I heard that noise twice and a very loud and steady noice sometimes coming from the transmission after speeding in a traffic light (from red to green).
After coming from a stop position and returning to normal driving transmission was making a rowing noise, difficult changing gears. Dealer has been contacted. Pleas provide further information.
