Brake Electric Antilock problems of the 1996 GMC Jimmy - part 1

I am having a problem with my anti-lock brake system. I have a 1996 GMC Jimmy and any time that I apply brakes and there is a difference in road conditions (pavement to gravel) while applying brakes there is always an extended stopping distance and no control. We have pine needles that gather on the side of our small road, making small mounds. If I apply my brakes while going across these the car will not stop. It makes a "pong" sound a couple of times, then it will finally stop. Luckily there has been no oncoming traffic. This has been happening every since I have had the vehicle. I have contacted a Chevrolet dealer in the past and they informed me there was no recalls on vehicle.

There is a recall regarding the abs system (and increased stopping distance) for the 4-wheel drive 1996 GMC Jimmy SUV. I am having the same problem with my 2-wheel drive Jimmy, but there is no recall on it.

F brakes suddenly engage from acceleration anti-lock system does not function properly. Vehicle will slide as if on a slippery surface.

Called Gmcabout voluntary NHTSA campaign #661006000 said, until mandatory will not do anything. So much for their concerns about this product failing. No safety dedfect listed.

When apllying brake at 15-20 mph there is extended stopping distance. Dealer replaced abs sensor.

Excessive effort needed to use brakes. There was a recall issued for brakes, and manufacturer performed service on vehicle; however, problem still exists. Please provide any additional information/attachments.

I would like to suggest that the entire 1996 GMC- Jimmy series made need to be recalled because the owner has to many repairs to be done on the vehicle. The services engine light comes very often to indicate repairs on the truck and their are to be problems with this 1996 Jimmy. I suggest a total recall of this vehicle and this vehicle is unsafe to be on the road. It has a very bad braking system abs.

Faulty brakes caused consumer vehicle to rear end another vehicle, consumer believes this failure is related to a recalled transfer case selector switch which may send an incorrect signal to the abs module thus resulting in longer stopping distance. Nlm.

While trying to slow down at an intersection vehicle perceeded into the intersection.

Recall 99v193000/abs. Recall notice was received after an accident. While traveling at highway speed of 60 mph applied brakes in an emergency situation due to another vehicle pulling in front, as applying brakes, vehicle continued on, even after pumping brakes three times. Vehicle continued until hitting other vehicle's rear bumper. Upon impact, driver's air bag did not deploy. Dealer/manufacturer were not conacted at this time. Please feel free to provide any further details.

Vehicle was experiencing the same problems as enumerated in manufacturer's recall 9332. Vehicle malfunctioned, causing extended stopping distance during stops. Vehicle has been taken to the dealer,but dealer refused to do recall repairs since this particular vehicle was not included in recal 9332 due to VIN. The effect could cause consumer to be involved in an automobile accident w/o prior warning. Extended stopping distance occurs on occassion when brakes are slammed on.

Recall 99v193000/abs: while approaching a stop sign and applying brakes, vehicle would not stop properly, resulting in an accident. On two occasions, on the same day within 20 minutes apart, vehicle rear ended another vehicle due to extended stopping distance. Dealer notified. Provide further details.

Recall 98v150 001/windshield wiper wiring & 99i006000/GMC abs : received two recalls notices. Dealer refused to honor recalls because of a salvaged vehicle, and informed consumer that repairs would be at consumer's cost.

While driving at any speed consumer could step on brake pedal to stop or reduce speed. But when driving over a frozen spot or gravel, vehicle won't stop immediately, instead will extend the stopping distance. Since the initial report, the system has been reprogrammed and is now functioning much better.

Have taken vehicle to 2 separate dealers with no satisfaction. No safety defect mentioned in summary.

While driving and coming to stop consumer had to use excessive force to stop. While coming down a hill at about 25 mph and coming to a stop applied the brakes, and consumer felt abs was trying to kick in, and then pedal went straight to the floor. GMC service dealer was suppose to fix all recalls that needed to be done. Dealer told consumer there were no recalls to be done. Consumer feels that this is a safety concern. Recall 99v193000.

When braking the brakes make a noise and have lost vacuum power and gone straight to the floor numerous times. The first time was when attempting to brake when going down an incline to turn into a parking lot. A slight bump when braking and the brake pedal went to the floor. A few seconds later, I was able to brake again. This has happened more often on wet or slippery surfaces. On 07/21/00 I was in a parking lot when another car was pulling in front of me. The surface was still wet and slippery and when braking, the brake pedal made a noise and then all braking ability is lost, the brake pedal goes to the floor. Luckily there was no accident. This problem has happened to me numerous times. I brought my vehicle in for the abs recall the end of 1999 and told the dealership about the problem. They couldn't find anything wrong. I travel a lot with my family and a braking problem is very scary!!!.

While driving at about 30 consumer tried to put on brakes before coming to the intersection and brake pedal went to the floor. Consumer let the pedal up again and tried to put on brakes , and car still did not stop. Was forced to go through the intersection. Now pedal will go to the floor before and then stop.

When braking while going over a bump, the brake pedal goes all the way to the floor, and does not stop the vehicle. This has happened numerous times.

When putting on brakes there is an air sound. Then consumer has to push down harder.

Was driving vehicle approimately. 50mph when another vehicle made a turn in front of consumer's vehicle. Applied abs brakes, vehicle failed to stop right away. Had a slow reaction time. Taking vehicle to dealer's to check.

No summary listed for abov evehicle.

When the brakes were applied at 35mph, the pedal went to the floor resulting in extended stopping, causing a minor injury. The dealer has been notified.

While traveling in rush hour traffic at a speed of 50 mph consumer tried to apply the brakes to stop and the abs did not allow maximum braking to stop vehicle.

Had just placed vehicle in cruise control. Inadvertently pushed shift too far into neutral. This caused engine to roar & not leave cruise control. Applied brakes quickly & vehicle went into a skid. Abs did not work. Hit an embankment & rolled over. Engine was disconnected.

While driving at any speed the brake pedal goes to the floor causing noise which results in failure. However, vehicle was taken to dealer on two occasions, dealer cannot determine the problem.

When the brakes were applied under normal braking, pedal went to the floor , resulting in extended stopping distance, and causing an accident and minor injuries dealer and the manufacturer have been notified.

This is the second Jimmy I drive (too loyal for my own good. ) the first one a 1995. Also had a booster failure at around 40,000+ miles (luckily I was able to coast on that occasion to a full stop without causing any damage to anyone. This one a 1996 has failed, like clockwork, at 45,000 miles.

While driving at 20mhp brakes gave out. When applied the brake pedal went to the floor, and brakes made a grinding sound. The vehicle stopped after coasting about 30 feet. Dealer was contacted, and told consumer that they could find nothing wrong with brake system.

Very poor brakes, pedal spongy and has been since 20000 miles or less. Dealer contacted company and no response other than some spongy knees is normal. Been living with miserable brakes until recent nearly disasterous accident because the brakes went to floor with no real affect. Able to push brake to floor easily with constant light pressure. Dealer says that now to fix will be expensve even though the vehicle always had lousy brakes.

While driving vehicle about 40 mph the rear brakes do not stop vehicle. Dealer was contacted.

Abs brakes have been replaced three times. When brakes are applied they vibrate and extended stopping distance occurs. Brakes wear out. Right wheel seems loose. Dealer contacted and attempted to remedy the problem. Problem still exists.

The defective braking system malfunctioned due to a electronic braking module which resulted in loss of braking system. The pedal went to the floor which almost resulted an accident. Dealer replaced electronic braking module and the valve assembly.

Upon applying brakes, vehicle slowed down, then suddenly accelerated, causing accident. (qcaw).

Consumer was coming off a ramp at approximately 15-20 mph went to apply brakes when vehicle began to pulsate, and felt as though vehicle was accelerating instead of slowing down. Heard noise and wheel rotating. Vehicle proceeded to roll forward for at least 20 feet, causing the consumer to rearend vehicle in front. Dealer cannot determine problem.
