1997 Chevrolet Blazer: jerking or lurching

Filed Jan 7, 2004 · Brakes · 89,000 miles · WI

This is a 1997 chevrolet bazer. The anti lock brakes on this vehicle is defective and ingages under varying conditions. The vehicle is unsafe in slippery conditions. Front sensors have be checked. This vehicle will engage anti-locks at times when brakes are not applied. Brake switch checks ok. Pedal will drop under most stops and anti-lock will scream and apply. A jerking brake action is present. I do know there is a recall on 1994-1996 models. By looking on the internet I see that I am not alone in this problem. Hubs are ok. I think the trouble may be in the control unit, but no trouble codes appear and scan tool indicates no trouble. I think gm has produced defective units. This car has 90000 miles but has had excellent care and no damage. I would like to know how to disconnect these anti-lock brakes. They are unsafe. There appears to be no way to detect the problem.

When first experienced we were coming home from hershey on a hot day when we came to a traffic light. When we proceeded the transmission shifted real hard into second gear causing us to jerk back as the truck jerked forward. This problem continued everytime we would come to a complete stop. We were able to make it to our mechanic and drop the blazer of. The next day when the mechanic looked at the vehicle he could not detect any malfuctions. Approx. One week later we drove to new jersey, the truck was fine until we came to our first traffic light in ocean city nj when the problem started again but this time the check engine light came on. When leaving nj the problem started when we had to stop at our first toll, this time I pulled over let the blazer rest for a while, then started back home and it was ok for awhile but then started acting up again so I pulled over and turned the truck of for about a minute and it was ok for a while again. I noticed that everytime it acted up and I pulled over that I just had to turn the vehicle off and turn it right back on and it would be ok for a while. When returning home our mechanic could now scan the service engine light and reported gear slippage. He talked to a transmission specialists who said this seems to happen on long hot trips, who suggested that this problem can last for years before the transmission would need to be replaced. Contacting aw golden they said they could not help us because the warranty had expired at 36000 miles and we had 41196miles. Contacting gm they said the same but if we would trade it in they would give us a 2000 dollar loyalty. We declined because we like the blazer and would have liked them to give that money to fix the problem. Contacting bbbautoline they said they couldn't help us. We just came from phila. And the problem occured again to and from. Checking the internet we noticed several problems with gm transmissions and decided to contact the federal safety agency.

Ongoing problem with accelerator pedal sticking. Has been fixed once and have an appointment to check again. The accelerator has to be pushed hard at times causing a jerky motion. Feels very unsafe.

Transmission had to be rebuilt after blowing. Transmission now jerks intermittently from 1st to 2nd. Brake pads wear extremely quick. Wiring harness under drivers seat had multiple shorts, causing no power seats, power locks, and flahing interior lights while driving.

After vehicle runs for 30 minutes, transmission jerks when shifting from 1st to 2nd. I was told that the valve body needed replacement, and the valve was sticking. It will cost $1000. Gmc customer service department said there is nothing they can do to help me. It is apparent that the 97 blazer's had serious problems with both the brakes and the transmission but don't want to do anything about it. All they want to do is replace my valve body with a newer updated version now that the bugs have been worked out but at my cost. There is no reason that a transmission on any car should have problems at this mileage. To top it off, most of my mileage is highway. I also put my 4th set of brakes on at 41,000 miles. Dealer said 1st set were defective at 18k, 2nd set was only a 10k brake at 29k. Problem was never fixed and I gave up.

Transmission started to jerk when going from 1st to 2nd gear. Tried to check the transmisison fluid but the dip stick could not be taken out because it was entirley rusted. The whole dip stick and holder is rusted. There was a tsb put out by gm but they will not pay to have this fixed. They stated they found something else wrong with the transmission that the extended warranty will have to cover. My suspisions are that the rust caused the problems. Dealer stated that I would have to pay for the dip stick ad dip stick holder. Still waiting on the extended warranty people to see if they will cover fixing the transmission. Should not have to pay anything due to a faulty transmission dip stick holder that rusts!
