GMC Sierra owners have reported 34 problems related to brake light on (under the service brakes category).
While towing my boat I experienced brake failure. The pedal went to the floor with no pressure. Brake warning light did not come on. We were on a dirt road with no traffic and were able to stop without incident. After inspecting the brake lines a leak was found in one of the lines under the drivers side door before the line enters the brake modulator. All the lines are rusty and need to be replaced. I contacted the GMC dealer and although they have seen the problem before they are unaware of any safety problems with the brakes and that gm has no fix for the problem. They estimate the cost to replace the brake lines to be about $1200.

While traveling in my 2003 GMC Sierra truck at approximately 45 mph I stepped on the brake pedal to stop at a stop sign and the pedal went 3/4 of the way down to the floor, then the brake light came on and the truck did not stop as quickly as it usually does ( glad I was not going any faster) . Upon checking the truck it was discovered that the front drivers side steel brake line had a hole in it due to corrosion and there was no brake fluid in the master cylinder .

Driving on west stone drive kingsport, TN, a vehicle cut me off trying to get thru a traffic light, I locked my brakes down hard as I could, I could feel the abs system working, I was able to stop about 12 inches from the other vehicle. When I pulled out after the light changed to green, I was traveling down a slight grade, depressing my brake pedal lightly, the pedal went all way to the floor board. . I took the truck to a local shop to have it checked, one of the brake lines behind left front wheel had ruptured. When the mechanic started the repairs, he called said all lines on this truck were extremely rusty, (he asked what I wanted to do) I said fix it right. In making the repairs all lines were replaced. . I have pictures of all lines that can be sent. I also have all of the brake lines that can be looked at and or analized.

I was parked on a sloped driveway (about 10 - 15 degrees). I started the engine, stepped on the brake pedal and took the car out of park into drive. Brake pedal was normal. I started to roll forward and when I pushed the brake pedal the car did not slow. I slammed the brake pedal and it went all the way to the floor. At this point I went off the end of the driveway onto a 45 degree downward sloped lawn; then into a wooded area at the top of a ravine. I slammed into a tree. The car was judged a total loss by my insurance company. I did not get a brake warning light. The airbags did not deploy. The car was serviced at a union park GMC (wilmington, DE) two days prior. Including brake inspection. Cause of brake failure was determined to be ruptured brake line. Both front and rear brakes were failed.

Pulled up to the carwash. As I was preparing to put money in the machine,I heard a hissing sound. Brake pedal went to the floor & brake light came on. I had no brakes whatsoever. Was able to roll back to a vacant area & stop with emergency brake. Truck is still in the shop where mechanic is replacing all the brake lines. He said this was common for this truck & the lines were all bad.

I have a 2004 GMC Sierra that has an electrical issue with the abs or brake system. The brake light, abs light and service brake system light goes off at random times. Might have something to do with the air conditioning because the a/c draws power from the battery and I can see that a certain level the indicators go off. Most of the time the lights chime and blink when I apply the brake but it also has happened when just turned the truck on. I've replaced the rotors and pads to still have the problem. I'm not sure if it's a ground or sensor that is failing. I've found TSB for regrounding, failing sensors, or ecbm. Still haven't found the correct diagnosis. I just hope the abs functions when I need it.
The first day I noticed that the brake pedal went closer to the floor before the brakes activated. The second day the pedal nearly touched the floor and then the brake warning light came on. I took the vehicle to my neighborhood indy tire center where they quickly determined brake line failure near the left rear wheel. The brake line had rusted completely causing a hole and rapid loss of brake fluid. A new teflon coated main brake line and fittings was installed along with new brake fluid. Other brake lines were examine and found to be rusted but not compromised. The total cost of repair was $461. 38.

Driving 30 mph in traffic. Light turns red . Cars in front of me apply brakes . I applied my brakes. Brakes instantly felt spongy and abnormal. Applied more pressure with 2 feet and brake pedal went to the floor with no warning at all. No brake light on dash came on just went to floor. Was determined by my mechanic that the brake lines had rotted and I had a catastrophic brake failure loosing major brake fluid at the accident site.

Stepped on the brake to put the truck in gear when it was noticed that the brake pedal went all the way to the floor! backed up, pulled forward, there were no brakes! vehicle was carefully driven home using back roads and transmission braking along with limited pedal braking. Brake light came on just before arriving at home, 10 miles down the road. The truck is presently in an independent repair facility. All metal brake lines are to be replaced at significant cost to me. Upon inspection it is apparent that the brake lines are more of substandard material. All metal lines show excessive corrosion and deterioration for a vehicle of this age and mileage. The truck is my wife's and was rarely driven during winter months.
Failure of abs module caused abs light and red service brake lights to come on. Replacing both front hub bearings (including both front abs sensors and wiring) and repairing the ground strap on the frame for the abs system did not fix the problem. Service brake system has new calipers ,rotors,and pads and a full inspection revealed no problems or failures. Abs module is still on vehicle but will be replaced next.
Brake warning lights intermittently activate while driving. Brakes appeared to be functional until occasion arose at 65 mph where hard breaking was required. Right rear tire locked up and severe tire wear resulted. Excessive slowing distance was experienced. Vehicle at non dealer repair shop parts will be available.
: the contact stated the brake light illuminated. The contact pulled the fuse to the abs to have braking power at low speeds of 15 mph. There is an NHTSA recall, 05v379000 concerning the service brakes, hydraulic: antilock, however the recall did not remedy the problem. The dealership cleaned the sensors; however the vehicle is still having the same problems as indicated in the recall. The dealership would not offer a second repair without charge under the recall.

About three years ago I took my 2000 Sierra truck to my GMC dealer after experiencing a few low speed abs activations and brake failures causing me to drift into oncoming traffic. Since tandom log trucks are frequent travelers on our local roads, I wanted to resolve the problem right away. My GMC service manager informed me that the only way to correct the problem was to replace the front hub assemblies containing the wheel speed sensors at a cost of $500 each for parts only. I decided against that idea and opted to remove the abs fuse under the dash board. I kept inquiring at the dealer about any gm sponsored repairs and finally read about the August 29, 2005 recall notice which involved cleaning, sanding, and lubricating the wheel speed sensors. The recall service work was done on 10/13/05, according to service bullitin #05068, but my truck continued to drift into traffic as before. This time I removed the abs fuse from under the hood so I could finally use the cruise control again. The service manager has since told me that there is no authorized follow up procedure other than to replace the hub assemblies or speed sensors, at my expense. The brakes function adequately without the abs fuse, but the red brake failure light on the instrument panel is on continually, as well as the amber abs light. If I go back to removing the interior abs fuse, the red light will go out and should be available to indicate any other cause for brake failure, but I sacrafice the cruise control. Gm has admitted that they designed a defective abs system that is prone to rust and corrosion in certain "rust belt" states and provinces of canada and they are aware that these vehicles have been unsafe to operate. The ineffective recall repairs to my truck cost general motors $46. 88 on the invoice and yet they expect me to pay about $1,200 to really repair and replace their defective parts. I don't think so.
Abs brake system is not working correctly. Tried to call gm, and they will not return the calls. The brake light also comes on. Car vibrates when applying the brakes.
The anti-lock brakes do not operate, making it difficult to stop the vehicle at various speeds. Manufacturer was contacted by owner. Brake light and anti lock brake light came on in the dash board. The consumer stated that he heard a motor r unning underneath the vehicle.
Anti lock brakes fail at low speeds contact must use parking break and place truck in neutral in order to stop. This causes extended stopping distances. Almost crashed 4 times due to brake failure. Actually made contact with another vehicle but no damage occurred. No brake light warning came on. Problem progressed with time. 10 mph and under is the speed at which problem occurred. Vehicle was taken to dealer for repair on 4/11/05. Problem was fixed at a cost of $877. 09.
While driving abs brake light appeared on the dashboard intermittently. Consumer contacted dealer, but problem still occurs.
While applying the brakes, the abs and brake lights would come on intermittently. The dealers mechanic stated that the abs brakes needed to be replaced. The abs failed as a result of abs switch failure. Abs motor stays running even with ignition key removed and engine off. The dealer quoted a price of $900. Dollars for repair. This seem to be quite common.
Abs pump runs even with key off! only way to stop it is to pull fuse. Abs and brake warning lights stay on all the time. Did not initially notice the problem until I made a tire screeching panic stop. Dealership stated no recall.
Anti lock brake system light came on.
Abs module stays on whether vehicle is running or not, abs will still be active, and causes the battery to run down. Dealer notified. Consumer unplugged the module which caused the brake light to come on. To turn the brake light off, consumer had to replace the module.
When I started my truck I heard a humming noise and my abs and brake light was on. I turned off the truck and the humming noise continued. I looked under the truck and heard the abs module was still on. So I pulled the fuse to the abs system and and the module stopped running. I drove the truck to see if there were going to any problems and found there to be none other than the abs not engaging. So I drove the truck home and parked it hoping to get it to the dealer on Monday. I checked online to see if anyone else has had this problem and I can see it is a pretty common problem. I was wondering if anyone had found out if this was a recall yet or if gm has decided to pick up the charge for this problem since it so consistent with these trucks or if someone may have a fix for the problem other than replacing the part because of the expense involved. If so please e-mail at isaacandjen@aol. Com .
Abs pumps run continuosly even when vehicle is turned off, also abs light is illuminated while pump is running. Consumer unplugged wire to stop constant running, vehicle will stop when brakes are applied, but brake pedal feels softer than normal, dealer was contacted. Pump failed after attaching a boat trialer. Consumer disconnected abs pump as instructed by dealer, however doing so illuminates the abs and brake light.
Abs light and brake light came on the dashboard and the abs pump module continued to run even after the truck was turned off.
Abs brake light remains illuminated due to a malfunction within abs brake pump, which locks up when brakes are applied, also pump continues to run after vehicle has been turned off, dealer has been contacted.
After starting vehicle in cold weather brake light came on, and brakes locked up. Vehicle would not move. Once vehicle got warm it still would not move. Please provide any further nformation.
Both the brake and abs lights came on. Per dealer the faulty piece causing lights to come on was the ebcm. The piece was on national back order, and would not be availalbe until 06/22. However, dealer did not assure the consumer that the brakes were totally safe. With faulty brakes, consumer has a fear of driving. Faulty brakes could cause an accident.
Abs brake light illuminated and remained on indicating a malfunction within the system , cause unknown. Please give any further details.
Anti lock brake light illuminates intermittently and when the light is on the brakes don't work, dealer says vehicle is not cover under current brake recall due to VIN. Nlm.
