Brake Sensor problems of the 2002 GMC Sierra 1500

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.

The failure mileage was 108,000.

Abs sensor in wheel hub failure this is one of four identical failures of this part in this same vehicle.

Failure of fourth abs hub sensor on this same vehicle each costing between $450 - $600. To replace.

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.

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.

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.

- 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.
