I left my house for work and approx. 3 blocks from my house I attempted to slow down to make a right hand turn. I pressed on the brakes and the pedal went all the way to the floor. I had no brakes. At this time and this was the first time, the brake light on the dash came on. I was driving at 30 MPH with no brakes, I coasted into a parking lot and used the parking brake to stop the truck. Outside and under the drivers door of the 2004 sierra extended cab there was brake fluid leaking. The 8 year old truck had rusted brake lines that failed. My concern is that I lost all brakes without warning. After a little research I noticed many of these trucks have the same problem. They are 5000 pound torpedos on the road and without warning. Will something be done before a serious accident occurs? I tried contacting gmc via their website e-mail but an error message occurred. Try a complaint on their site.....it don't work!!!
2004 GMC Sierra brakes complaints
Page 3 of 4: complaints 41 to 70 of 74, newest first, as owners wrote them.
I was leaving my driveway and completely lost all brakes and could not stop. I had to slam on the parking brake to stop. A brake line blew. All the brake lines and fuel lines are completely rotted.this vehicle isn't even 10 years old yet. The fuel line and brake lines are a major safety issue. This truck is a 2500 and I use it for towing trailers if that brake line went while towing it would have been a major accident. The entire underneath of this truck is so rusted the frame brake line and fuel lines are terrible. Someone is going to get killed from gm's cheap steel.
All brake lines are rusted about into... One busted, I had been on interstate for two hours and luckily I pulled into my driveway and lost all brakes. Brake lines should not be in such a rusted state for this truck, gm should be made to recall for this problem ... This is life threatening under such conditions! And should be addressed as soon as possible.
I was coming down a hill near my home & tapped on the brakes to slow down. Suddenly alarm bells started dinging, the engine warning light came on & "service brakes immediately" popped up on the message center. The brake pedal was slightly softer than normal but I made it home ok. The following day I took the truck to my mechanic to have him check out the problem. Much the same as many others have complained about, all four brake lines between the master cylinder & the ABS controller were badly rusted out while one had failed completely (causing the alert/alarm). The lines from the ABS controller to the individual wheels are also completely rusted but as of now haven't failed. He replaced the one ruptured line & suggested that I have the others done as soon as possible as they all look very bad. Looking at the undercarriage of the vehicle there was very little overall rust on any other components or the frame, just on the brake lines. Estimated cost for replacing all the lines as needed - $800.
Brake fluid all leaked and I barely stopped the truck on my home driveway. Dealer says I need to replace all four metal brake lines.
Entire brake line failure do to rusted brake lines.
Brake lines rusted through at left side just below drivers door, which resulted in a loss of brakes!!!!! After further inspection all brakes lines are severely rusted and must be replaced. This is only a 2004 truck!!!!!!!!
When attempting to stop on dry pavement, the ABS activates at a very low speed, approx 5mph, the truck will not stop as expected. Almost caused my wife and kids to hit vehicle in front. Mechanics have stated this is a common problem with gm trucks and the hub with speed sensor will need replaced or repaired at owner expense.
All brake lines on my 2004 gmc sierra pickup are rotted and need to be replaced, the truck has 48,014 miles on it. General motors needs to step up and assume responsibility for this before someone is seriously hurt or killed, if no one has been already.
I experience brake pedal pulsation (low speed ABS activation) when rolling to a stop. My gmc onstar report says there is nothing wrong with my ABS braking system yet I have this problem. The problem seems to be rusted and/or froze up wheel speed sensors as verified by two different mechanics. I understand they were recalls by gmc of other trucks experiencing this same problem. I really hate to pay $750 for new front wheel bearing assemblies. I want my truck recalled for this problem. There is a gmc technical bulletin 03-05-25-007d. I am not sure the ABS will function properly when really needed??
My vehicle has 76,800 miles and all of the brake lines are rusted and need to be replaced. I understand that there may be a recall for this problem. Please forward any information related to this issue.
While at our town dump on the 2nd of november of 2011, I proceeded from 1 drop off location to the next (as usual), when as I slightly depressed my brake pedal to slow, the pedal went right to the floor. I almost ran into another vehicle had I not depressed my emergency brake. There was nowhere to turn to as vehicles were everywhere, "wow"! Not knowing what was wrong, I continued to the next drop off point with virtually no brakes. I used the e-brake again to stop. I told the dump attendant what just happened and he said, "that's probably why you're spewing what looks like brake fluid from your left rear. Sure enough, upon inspection the line blew. I got the vehicle to the local gmc dealer. Long story short, they wanted $360 to fix the brake line. [xxx] the service manager said it looks like the rest of the lines don't have much time left either. "not good!" I got the vehicle home, called my son who is a mechanic for a local jeep dealer and he fixed the last foot or so of the brake line where it blew. He said "dad come here". He showed me under the hood where the visible brake lines are virtually rotted and probably ready to go. I am partially disabled and out of work. I couldn't afford to have the dealer replace the whole brake line let alone now having to replace all the lines! I saw on the internet that this is an ongoing problem. Why is there no recall on this? If I were somewhere else going even faster, this could have been bad. Why are the car companies not required to use higher quality/more corrosive resistant lines? Yes I understand that would raise the sticker price, but for a life? This is brakes on something that rolls at very high speeds we're talking about here and nothing is being done about it as far as I can see? Plus my truck is less than 7 years old as well as all these other vehicles and I had only 84,375 miles on it when it happened. Recall? Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
Rigid brake lines from the master cylinder to the ABS module rusted through causing a catastrophic failure of the hydraulic brake system.
Tl* the contact owns a 2004 gmc sierra. The contact stated that while braking for an approaching traffic stop, the brakes traveled to the floorboard abnormally. The dealer and manufacturer were notified of the failure but denied any assistance with repairs to the vehicle. The vehicle was repaired but the failure recurred. The failure mileage was 85,000 and the current mileage was 86,000.
Tl* the contact owns a 2004 gmc sierra. The contact stated when he accelerated and attempted to shift gears, the brakes were applied and the brake pedal extended completely to the floor board. The vehicle was towed to a dealer who diagnosed that the brake line was defective and would need to be repaired. The vehicle was repaired. The manufacturer was notified, but did not assist with the failure. The failure mileage was 50,000 and the current mileage was 60,000.
Tl*the contact owns a 2004 gmc sierra 1500. While driving approximately 30 MPH, the contact applied pressure to the brake pedal and noticed increased stopping distance. The brake pedal depressed very easily when the pressure was applied. The failure occurred whenever the contact applied pressure to the brake pedal so he replaced the brakes himself. The failure continued so he notified an authorized dealer and was informed his vehicle was not included in the recalls associated with the federal safety agency campaign id numbers 05v043000, service brakes, hydraulic or 04v045000, service brakes, hydraulic. The vehicle was not repaired. He also stated that his speedometer and oil gauge on the instrument panel displayed incorrect improper readings. The failure mileage was approximately 35,000 and the current mileage was approximately 48,000.
Abs brake system activates at stops. Had to pump brakes to stop vehicle. Dealer had to replace corroded front wheel speed sensors. Sensors should last longer than four years, should last the life of the vehicle. Cost $378 to repair.
When returning from a trip, the truck was shut off and the ignition key was removed. The truck continued to run, flashed code p0758, check 4wd, check brakes, ABS failure. The truck did this for two days while driving home and would stay running without the key from 2 to 16 minutes and could be put into gear and driven, all without the key.
2004 gmc sierra brakes fail when there is snow on the ground. *ts the brakes would grab and grind while braking which caused extended stopping distance. The brakes work properly on dry surfaces.
Dt: the contact stated the front brake lines were rubbing against the caliper, causing a hole/loss of fluid, and failure in the brakes. The vehicle was taken to a dealership, where they replaced the brake line, and placed a rubber boot where the wearing occurred. The dealership said defect was a result of the suspension modification to the vehicle. The contact took the vehicle to another mechanic, who stated the rubber boot would not stop the wearing, and the modification could not have caused the problem.
Dt: the contact stated while applying the brakes it was difficult to stop the vehicle. The vehicle slid before it came to a complete stop. There was extended stopping distances when trying to stop the vehicle. The dealer could not duplicate the problem with the brakes.
Dt: the consumer stated that the 2004 gmc sierra was having problems with the brakes. The vehicle had no stopping power. The consumer informed gm about this problem a year ago and they have worked on this problem several times trying to fix the brakes. However, the problem recurred. Today the consumer was waiting on gm to get back in contact with his dealership. The consumer talked to the dealership last week and they still had not heard from gm. The hold up on the consumer getting the brakes fixed was gm doing the work under warranty. Speed was not a factor in the braking power.*ak *mr the consumer stated gm did contacted him and they decided they were not going to do anything more to fix the brake problem.
Dt: contact states the brakes have a very soft pedal. It doesn't seem that the anti- lock brake system is working. To make the vehicle stop the pedal has to be pressed all the way to the floor. The service dealer states this is a characteristic of the vehicle. The weather conditions have no influence on the braking capability of the vehicle. The consumer has contacted the manufacturer.*ak
I notice the parking brake losing is capacity to brake properly. I was minor at first the one day it just quite working properly. I wasn't aware of a recall on it at the time. I took it into a dick keffer in charlotte. They say there is nothing wrong with the parking break. I've also talked to gmc about this. Gmc says there is a recall on my truck but wouldn't fix it because the dealer says there's nothing wrong. I do know there is something wrong. My truck is a 2004 gmc sierra crew cab long box.
Dt: purchased vehicle in november 2003, and on 12-22-03 had a minor accident. This occurred at a low speed at which consumer tapped another vehicle from behind. Took vehicle to a dealer. He checked the vehicle diagnosticians via computer, but the codes checked out as well as a test drive and inspection from the service department. This checked out as adequate, no problems found. About 2 months later, experienced a similar accident. Consumer called gm to inquire about this problem. Again taken to dealer, and no problem found. 5-7-05 experienced another accident that resulted in 3 injuries. The accident happened as consumer was approaching an intersection from about a distance of 60 feet and traveling about 45 MPH when applied brake failure and suffered a complete failure with no brakes at all. "brakes would not even grab." glided through intersection striking another vehicle that resulted in 3 injuries. Took to dealer who checked vehicle and again found nothing wrong yet consumer feels as though brakes are not functioning properly.
Dt: while driving and approaching a stop sign, consumer hit the brakes and the ABS activated as if there were no brakes. Consumer had to let off again and push brakes again to stop. By that time vehicle had rolled out in the road past the stop sign. This was the second time something like this had happened. No repair work performed. Probably was under 10 MPH when ABS activated.
While applying the brakes the pedal went to floor. Driver noticed that the pedal was hard, and vehicle would stop on its own. Driver took vehicle to the dealer for inspection, and mechanic determined that disc brakes and power booster needed to be replaced.
While driving 5 MPH consumer lost power steering and braking control. Consumer managed to pull over, and had the vehicle towed. Dealership was notified, but did not resolve the problem. *ak consumer states he stepped onto the brake pedal and heard a loud explosion under the hood. The consumer immediately lost brakes and steering and smoke also poured from under the vehicle. Once he vehicle was stopped the consumer exited the vehicle and saw fluid pouring from the vehicle onto the ground. The hood was opened and the consumer saw the vehicle was taken to two different dealer but the found nothing wrong. The dealer replaced the hydrobooster assembly accumulator which had come apart. *bf
2004 gmc sierra pickup truck, notice brake problems at about 12,000 miles took truck to dealer to see what problem was, concerned was wearing brake rotors in front end, was told that rotors were defected from manufacturer thy were turned wrong at factory, they tried to correct problem by turning them at dealer problem returned at 30,000 miles, went back to dealer to correct problem then front rotors were replaced and rear rotors were turned also, again at about 34,000 miles problems with rear rotors occurred they refused to warranty them I feel that there's a wider problem then just a few truck and s.u.v. And a recall and a inspection should be done on all rotors from this year of manufacturing should be done for safety reasons I did save the rear rotors for measurement in the future if needed. *ak
Crash: 1) traveling on interstate at 55-60 MPH 2) poor braking ability to stop vehicle during panic stop.
