Brake Sensor Problems of GMC Sierra 1500 - part 1

You can constantly feel a bump,clunk & transmission slip when going from reverse to drive. This is dangerous as I was pulling a small boat and it came off the hitch hitting the trucks tailgate and causing damage to it. This will happen seconds after drive is already engaged. After 3rd time I took to dealer the mechanic gave me a GMC memo that states that this is normal for this model truck to do this. Mechanic stated gm has known about this issue for years. Are you kidding me ? sounds like poor engineering. I was never told this would happen pre purchase or I would of never bought the truck. Have had constant problems with this truck since I bought it. Have had the seat belt pillar cover fall off 3 times dealer says they will change seatbelt, waiting over 2 months and no parts or repair. I have a warning to service brake pad sensor monitor. Took to dealer and they say they can't get parts for it yet because gm is on strike and have been waiting for parts and repair for over 2 months . Have had a steering wheel column warning also. Dealer blames everything on software issue. My diagnostic report each month states truck is in perfect order even though I have had a warning light for over 2 months !!!!! now there is a recall for the seatbelt pretensioner that it might cause a fire ! what a piece of junk this truck is I tried to support the american economy by buying an american truck and look what I get ! I should of bought a Toyota tundra !!!!!!!.

Went to stop and the brake pedal pushed against my foot instead of going down. Was moving slowly and the brake pedal instead of stopping the car pushed my foot up from the brake pedal and I went over a parking brake. Mechanic verified that when wheel sensor goes bad the vehicle thinks the brakes are locking up and the abs system goes on pumping brake pedal. Happened multiple times as approached stop lights pushing me into intersection instead of stopping. . I believe when the wheel sensor is bad it should not put me or others in a dangerous situation.

The contact owns a 2002 GMC Sierra 1500. While driving between 3-8 mph, the brake pedal was depressed and the anti-lock brake system engaged, increasing the braking distance. There were no warning indicators illuminated. The contact mentioned that the failure occurred intermittently. The vehicle was taken to an independent mechanic where it was diagnosed that there was rust between an abs sensor and the hub in the front driver and passenger side wheels. The hub and sensor needed replacement, but the vehicle was not repaired. The GMC dealer (jeff wyler florence Buick GMC, 1154 burlington pike, florence, ky 41042 (859) 279-4590) informed the contact that the VIN was not included in any service bulletins or recalls. The manufacturer was contacted and confirmed that the VIN was not included in NHTSA campaign number: 05v379000 (service brakes, hydraulic). The failure mileage was approximately 165,000.

Due to a problem with brake booster vacuum sensor and brake booster large vacuum leak, extra pressure is needed to apply brakes. Brakes are essentially non existent in vehicle. Problem diagnosed by dealer. Dealer states this is not a normal problem with the braking system. This is a safety issue especially when driving and this unexpectedly happens. Vehicle was in motion when this happened driving at approximately 45 mph. I understand this was a similar problem with the 2014 malibu. Replacement parts are on order unknown when expected due to this not being a part regularly replaced (per dealer).

Thank goodness no one was hurt, and no vehicle hit when my brake lines burst on this vehicle. When repaired the mechanic said they basically rotted off from rust and that this is a very common problem on these vehicles. I understand some maintenance is normal on any truck, but being able to use your fingers to crumble parts of the brake line is not. You need to investigate this before people are hurt or killed, if some haven't been already. You also need to revisit the abs sensor problem from the previous recall. That fix did not work, so all I could do is disconnect them or chance an accident!!!!!!!!!!.

My 2007 GMC sierra has faulty abs sensors which activate at low speed stops and greatly extends the stopping distance of the vehicle. Searching th einternet usenet list it seems that a good portion of gm fullsize pickups and suvs have faulty abs brake sensors which activate during low speed braking. 1999 - 2007 vehicles seem to be the most affected and include sierra, yukon, suburban, and silverado trucks. Gm has known about the issue for many years and has issued a service bulletin on the issue but failed to issue recall, this leaves the owner stuck with the problem to deal with on their own.

This problem concerns my 2001 GMC sierra and gm's recall number 05068. The recall concerns the abs and a rust problem. I had the recall performed on oct. 19, 2005 and there was 47,249 miles on the odometer. I noticed a braking problem last week with my truck. After doing a search on the internet, I decided it was probably a abs sensor problem. I took it to the same dealer that did the original recall. They checked with gm regional manager and said it was already covered once and wouldn't cover it a second time. I had the repair done at the dealership on Dec. 8, 2010 and the mileage was 65,849. So the effect of the recall only lasted 18,600 miles. I know 5 years have past, but the same issue in that few miles? I sent an email to gm on Dec. 9 and they phoned me this morning. Said the vehicle age was such that they wouldn't do anything. If I had 150,000 miles or so on the truck, I wouldn't think that much about this. However, this is a problem that gm issued a recall on and from what a understand, the original recall did nothing but remove rust from the sensor and treat the surface. I would think a recall would last more that 18,600 miles. I don't know if you have had any other people with the same concern about the recall only stalling a problem later on down the road, but wanted to make you aware of the concern I have. The brakes will fail at low speeds when they are applied and the message center in the dash does not give any message. Thank you.

The contact owns a 2007 GMC Sierra 1500 classic. The contact stated that when applying the brakes, the brake pedal would drop a few inches and the vehicle would abnormally lunge forward. There was no warning lights illuminating. The vehicle was taken to the dealer who repaired the front wheel sensors and cleaned the mounting surface at the contacts expense. The manufacturer was called who informed the contact there were no recalls or warranties on teh vehicle and offered no further assistance. The failure mileage was 37,202.

Anti lock brake sensor corrosion causes low speed braking failure. Diving at less than 5 mph was terrifying. Almost hitting pedestrians at a crosswalk, rolling into an intersection, and almost hitting a stopped car in front of me. I took the truck to the dealer and they verified the corroded sensors. This was a recalled issue already complied with. No help from gm. They said the burden was mine.

Abs sensor activation at slow speed. The truck does not stop normally when brakes applied at slow speed. This is a known defect by gm and NHTSA. Recalls have been done but not in my state. This is a safety issue and the recall needs to be expanded to all affected vehicles. Despite gm saying that this issue is limited to 20 states and canada, this is not true. A search of the internet has shown this defect is nationwide. Abs was added to vehicles to help prevent crashes. This defect causes them.

Safety about GMC sierra truck abs braking system. There is a recall on this truck for abs activation when stopping and could cause a crash. I experienced this and they did replace or clean the wheel sensor and test for proper operation. Now I have the same problem but they will not correct it. This is not acceptable to me for I will be towing a trailer and depend on my brakes to stop. They want me to take it to the dealer at my expense. I told them that I disconnected the sensor and the brakes work fine. I believe that they correct this and also I did have a brake line failure where I had to pay them $700. 00 for the replacement of my brake lines. I am furious about the braking system and cheap building of our cars and trucks. Do investigate this and reply.

Lost approximately 80% of braking power in a 2003 GMC Sierra 1500 with 60,000 miles. Small leak developed in the metal brake lines. There was no sensor indication that fluid was low despite brake fluid being one quart low.

Had dealership replace driver side front wheel bearing because it was making a grinding noise. A couple months later the front brake pads and rotors were replaced. After the brakes were serviced, I started noticing that the brakes were pulsating, which was felt in the pedal, at low speeds. Took vehicle to the dealership and they said during the test drive that the abs system was activating unnecessarily. They then put it on the diagnostic machine for some reasons. I was told I needed to replace both wheel abs sensors. The dealership said that the abs has nothing to do with the brake pads and rotors. When the pads and rotors were replaced, again the vehicle was put on the diagnostic machine, but didn't pick up that the sensors were firing. I'm doubting it is coincidence that these things are happening at random. There has to be some kind of correlation between the wheel bearing being replaced, the pads and rotors being replaced, and now the sensors needing to be replaced. My vehicle is a 2003 GMC sierra and has 47000 miles on it. All this happened within the last 6 months and 1500 miles.

1. Anti-lock brakes activation at low speeds 3-5 mph. 2. Always the first time applied when cold after that at various times 3. This is the same conditions as NHTSA 05v379000 or gm 05068 which started in 2005. The truck was looked at then when there was no problems but when the problem is happening now gm says that it is only a one time recall. The dealer looked at the truck and said the hub was worn and needed replaced for $500 per side. When I questioned the service rep if the bearing was worn he said no. I then asked what was worn since the hub is the bearing. He said I did not have to have it repaired if I did not want to. I explained that I wanted the recall work done which was cleaning the rust from the sensor. I also stated that there are magnets on the hub that pass the sensor creating an electrical impulse so if the bearing was not worn are the magnets worn? he said the hub was bad and needed replaced. I declined the work. I complained to gm and they said that I was told it was a bad sensor and declined the work or further diagnosis. That was a lie. I then did the recall procedure of removing the sensor and cleaning the rust away. There is also no bearing play so the hub is not worn. The brakes now work fine. So a couple of things here. If there is a safety recall and it comes back as this did should they have done this work. Second the service department at joe ball GMC is running a scam and making money on people that do not know better.

Tl the contact owns a 2000 GMC Sierra 1500. The contact stated that the vehicle was repaired per NHTSA campaign number: 05v379000 (service brakes, hydraulic) by wehr Ford (11311 us-60 bus, mountain grove, mo 65711, (417) 926-3192). The contact stated that the dealer only cleaned the abs sensor for corrosion. Years later, the brake pedal failed to respond due to internal corrosion regarding the sensor. Also, the abs kept intermittently activating and caused extreme difficulty when braking. The brake pedal failed to stop the vehicle and caused the driver to have to reverse more than twice to prevent a crash. The dealer was notified of the failures and indicated that the abs sensor may need to be replaced. The vehicle was not repaired. The manufacturer was notified of the failures. The failure mileage was not available.

GMC & chev k1500 series pickup trucks 4x4 front wheel bearings abs brake censor unit I had 2 sets of these go bad on qa pickup with less than 35000 miles on it these wheel bearings are not bad they just become a little lose but are still in factory spec. There is a abs sensor in between them and the unit will malfunction in this condition which will not let you stop when on dry roads I ran through 2 stop signs trying to stop with 2 feet on the brake pedal this condition is not just with my truck I have over 12 friends that have the same truck 2002 thur 2006 and we have all had this happen to us if you want names and #'s I can get them.

My issue with my 2002 GMC Sierra 1500 regular cab long bed is related to an abs wheel sensor recall. I had my truck serviced in Dec 2005 for the recall problem. The nature of the problem is corrosion at the abs wheel sensor which causes the abs braking system to activate at low speeds when stopping which in turn increases the stopping distance. This is a safety issue that cannot be neglected. I had gone to the bob ross Buick/GMC dealership in centerville, OH on 4/30/2009 original dealer where I purchased the truck. They performed an inspection for $64. 95 plus tax and 10% shop supplies charge. They told me that since the truck was already serviced for the recall, that I am not covered to re-repair/rework the truck for the recurrence of the problem. I contacted gm customer care and worked with a representative named al and then after he said he couldn't do anything for me from gm corporate I was connected to gm district specialist donald howell (1-800-790-5700 x41958). Donald also eventually said that gm would not help with getting the work performed. The service request # for my case is 71-758818423. My requirement for resolution is that gm repairs the issue at no cost to me, most preferably by replacing the abs wheel sensors with new ones less likely to corrode. Im sure that the new product design has the corrosion issue in mind and has found a way to avoid it. As the repair history of my vehicle should state, the abs wheel sensors were cleaned and then spray painted with a corrosion resistant paint to fix the issue in Dec 2005. As an automotive engineer who worked for gm/delphi for 14 years of my professional career, I know that what was performed previously is not a permanent fix. I also am willing to bet that I am not the only customer with recurrence of this issue. Had it been fixed correctly the first time with new abs sensors - then the problem would not have recurred. I should also be reimbursed for the $76. 46 I had to spend for diagnosis.

The contact owns a 2002 GMC 1500 avalanche. Two years ago, the abs sensor was repaired on the vehicle under recall. Currently, the abs sensor is not working properly and the brakes do not hold in the middle of stopping. The dealer stated that the contact would have to pay for the repairs due to the previous recall repair. The NHTSA campaign id number was unknown. The failure mileage was 52,100.

Abs sensor engaging when not required at low speed braking. Occurs at almost every stop. A recall was issued for 98-02 models but is still occurring on mine and it is an 05. Dealer wants to clean sensors but cannot guarantee they wont get broken during extraction at a replacement cost of $280 a wheel. The vehicle is an 05 GMC sierra half ton. I live within the states defined by the previous recall and have been dealing with the problem for at least one year. This seems like something that should not fall financially to the consumer since it is clearly a problem with design that has been lingering for nearly a decade.

2003 GMC Sierra 1500 with 70k miles. Have had problems on different occasions with the anti-lock brakes at low speeds. Had to replace sensors on all 3 occasions. Also, brake line busted which resulted in a near crash into a home. After further investigation, all brake lines leading in the antilock brake component were severally rusted. All brake lines needed to be replaced at a very hefty price.

- the contact stated that while driving the 2002 GMC sierra with 10,900 failure mileage at 15 mph in the driveway he put the foot on the brake pedal and the abs system engaged , not allowing the vehicle to stop. The vehicle went through the garage wall. The vehicle was taken to a dealer, and they found four abs error codes. The dealer replaced the abs sensors on the front wheels. The current mileage was 11,002. Consumer has provided invoices for the dealer. Update *4/23/07t.

I have a 01 GMC sierra (light duty) that has the same problem with the abs breaking system as the trucks in recall in the north eastern states. My problem is I bought the truck in florida. . . Moved to delaware and have lived here the past ten months. . Truck is still registered in florida. . . And GMC won't replace the recall abs sensors because I purchased the truck in florida and its has a VIN number showing origination in florida. . . How ridiculous is this???????? is this legal to deny me a recall. . . . When I can prove I have a permanent residence in delaware????.

The contact owns a 1996 GMC Sierra 1500 extended cab. When attempting to decelerate or stop the vehicle the antilock brakes activated, and the vehicle took longer to start. The contact mentioned recall # 05v379000 concerning service brakes, hydraulic: antilock. The dealer stated that the antilock sensor needed to be cleaned. The contact will have this procedure completed before the hard copy of the ivoq arrives and will submit a copy of the repair invoice. The current mileage is 130,000 , and failure mileage was 110,000.

I have noticed problems with my abs in the front of my truck in the past year. Well my truck is now off the road so I have been driving my mothers truck and hers is starting to do the same thing its makes like a grinding noise in the front we took off the tires and the brakes were fine we can't figure out what else could be wrong and then a friend said its the abs sensors system.

The consumer stated that the abs system activated when the speed was at 10 mph on his 2000 GMC pickup truck. The front wheel sensor was replaced on the front end. The dealer said that the abs was inoperative and were not working correctly. The truck was out of warranty and the owner had to pay for the repair work. This happened in 2004. The owner did not contact the manufacturer at the time of problem. The consumer has not had any problems with the truck since then.

- while driving the 2001 GMC sierra extended cab at 20 mph she attempted to depress the brakes and the vehicle begaqn to slow down , then without warning the brake pedal went to the floor and vehicle accelerated. This failure resulted in a crash. The contact attempted to maneuver the vehicle to the left to avoid a collision, but was unable to, and the passenger side front bumper crashed into the driver's side passenger door of another vehicle. The road conditions were clear. The vehicle was drivable, however, the contact had the vehicle towed to the dealership. The contact stated there was a complete state inspection of the vehicle done by the dealership September 8, 2006, prior to the crash. The dealership replaced the front wheel sensor speed. The dealership investigated the vehicle after the crash and notfied the contact there was nothing wrong with brakes. The vehicle currently had 52300 miles.
