Low speed braking issue. Was in a parking lot trying to park moving about 1 or 2 MPH. Truck would not stop and it was like there where no brakes until I pressed as hard as I could. Does not do this at normal speeds
2017 GMC Sierra 1500 brakes complaints
Page 4 of 5: complaints 71 to 100 of 108, newest first, as owners wrote them.
On 9/2019 they supposedly did the reprogram to fix the hydraulic braking issue on my truck. It is now doing the very same issue again. I go to slow down or stop and feel like its not slowing down and I pump the pedal to get a good pedal to stop. It does this quite frequent now. Is there anyone who can help me see if this can be done again under recall?
This happened multiple times. The brake pedal is hard at low idle, and you have to stand on brake pedal to stop the vehicle. Typically happens when trying to back in a parking spot or in stop & go traffic the brake pedal becomes hard to push and truck doesn't stop as quickly
Tl* the contact owns a 2017 gmc sierra 1500. The contact stated that while accelerating at 85 MPH, the vehicle independently decelerated to 70 MPH without warning. The contact stated that the throttle no longer operated as needed. The contact had taken the vehicle to faulkner buick gmc trevose (4427 e street rd, feasterville-trevose, pa 19053) on two occasions however, the mechanics were unable to diagnose the failure. The manufacturer was also notified of the failure and informed the contact that they had never heard of such a failure. The contact then spoke to an independent mechanic who informed him that the defect may be linked to a speed sensor and a computer malfunction. The contact then took the vehicle to another independent mechanic who reprogrammed the computer software. The vehicle was repaired. The failure mileage was approximately 19,906.*dt
I was driving 50mph and was behind a semi as I started to pass him I noticed an oncoming car and decided there wasnt enough time to pass so I started to push the brake pedal to slow down and get back behind the semi and the brakes locked up which produced an uncontrollable spin in which I did a 180 degree spin and ended up going into the ditch backwards and tipped over on my side no airbags deployed either.
When I apply the brakes it doesn't want to stop and I have to push it down again almost like there is a issue with the vacuum on the brakes but it says my vehicle is not affected by the recall but the symptoms are exactly the same as the recall.
As I was back my boat in at boat ramp brake pedal was hard to press down had to almost stand on them to keep from truck going in the water. I researched this and seen where gm has a recall on the vacuum pump but I call the dealer they told me they wasn't a recall.
Gmc sierra was brought to dealer for existing recall regarding braking. Dealer indicated recall had been resolved. While backing the truck on 3 separate occasions since recall addressed, brakes become much less responsive with clicking sound. Brakes become hard to press and do not stop vehicle complete. This also happened while towing a boat down ramp. The vehicle has 28,000 miles and the issue did not occur prior to about a month ago. The most recent time was tonight while backing on level ground into garage. I have not had an accident as a result of this, but the recall was not adequately performed or did not address the issue.
At low speed or most of the time backing up brakes do not work well at all. Need to push very hard.
I was driving on I-4 towards orlando at 70mph following a safe distance traffic was coming to stop and I went to brake and the brakes wouldnt work properly and cause me to pull vehcile to one side causing me to crash saw life flash before eyes . Thankful to be alive , comes to find out there was a recall on it
Almost collided with other cars in parking lot because the brakes weren't working right also transmission shimmies between 50 and 60 MPH
Felt strange brake pulse turned into parking lot and power braking failed. Barely got truck stopped before hitting another car. Truck had to be towed to dealership
When I going in reverse the pedal brake doenst work
My truck braking system is going to the floor board of my truck. Making very hard for me to stop. They call themselves fixing it but the same problem is back. Really tired of this problem and other spend 1000.00 on springs and the vehicle was only a 1 1/2 old was told the warranty on cover it if they were broken a lie the dealership told me.
Our truck is less than three years old with approximately 69000 miles. The transmission just started slipping out of the blue while driving thru a neighborhood. While in drive it would move but once accelerating it would rev up and not change gears. This happened without warning, without an engine or warning light. We do all the necessary regular maintenance. In addition two years ago while the truck was a year old, the brakes went out while driving on the interstate. I guess it was the brake vacuum pump or whatever that didn't allow the brake peddle to be pressed which provided me with no brakes. Again with absolutely no warning! This later became recall issue but not before it had already happened to me! I understand there is a class action law suit against gmc for transmission problems and I would consider being a part of this. This is a 50;000$ and relatively new truck, this is unacceptable! The dealer now wants over 4000$ for repairs.
I own two gmc sierra trucks years 2014 and 2017 both trucks have severe lock up issues. I have gone to the dealership numerous times and they reset the computer but the brakes still lock up. This is an extreme safety hazard, and my wife and I are extremely scared that we will be in a fatal accident. There has been several times where we have almost hit a car or person walking. I am really concerned that these vehicles will cause an accident. My children are always in my trucks end it is extremely scary when every time I hit the brakes I am not sure if it will stop or not. This is an imperative matter.

Lost brake assist. Coming to a stop the brake pedal whet to the floor and the anti lock brakes started chattering. The brake pedal was hard as a rock and took 2 feet to stop. I was on a 170 mile trip and almost hit someone 2 times.
Original issue: brake pedal hard to push and truck did not stop normally at low speeds. Could reproduce issue usually pulling into a parking spot. My vehicle would have hit car in front of me if I hadn't used ebrake. Took to dealer, dealer applied software update to braking system. Upon pickup I discovered the original issue persisted and now had an additional issue. Now at almost every brake event, the ABS would engage and cause the brake petal to chatter/vibrate. Dealer and gm customer service tried to tell me that was normal after the recall update. I told them that couldn't be normal. It wasn't happening before. After not excepting that as a fix, the dealership started looking for other possibility's. After telling the dealer I was going to take the truck somewhere else they decided to replace the vacuum pump. The new vacuum pump fixed both issues! I'm just saying if the recall update is causing more problems then what it was intended to fix. Now there could be a more serious problem on the highway. Please look into these issues. I feel like gm is trying to hide a big problem.
I has some issues with my brakes when stopping at a red light. I stepped on the brakes and kept rolling forward and almost hit the truck in front of me. I thought it could be my pads worn down so I drove cautiously for a few days. I got a call a few days later from the dealership where I brought the truck from saying my on star notified them of a recall on my truck pertaining to the brakes. I thought good this could fix the problem. I took it by the dealer and they said it was a software update, and they did the update. I also asked them to take a look at the break pads so I could rule it out or do something about it. They said I have 60% of my brake pads still left. The next day I was going to work and I got to the parking garage where I work and noticed it was doing it again. I pressed down on the brakes to back up and I kept rolling forward and had to press down hard and to the floor so I could stop. So far there was not a crash but I feel its only a matter of time. This is a major safety issue for me and my family and feel there should be some sort of recall to fix this.
A few times my brakes while going slow would get very tight and not work. Well today after church I was leaving the parking lot. As the car in front of me moved forward, so did I. When I tried to stop I couldnt. My brakes got hard and went to the floor and I ran right into the car in front of me
Anti-collision system is activated, I apply breaks, break peddle is soft and goes to the floor, I swerve to avoid collision and quickly pump the breaks to regain peddle and apply breaks again (this time brakes engage). 6 different times this has happened. 4 times on the interstate during rush hour and twice on a highway. Car in front of me slammed on the breaks cause the system to activate and me to react. It appears the system overrides the brakes taking control away from me. However, the system does not brake the vehicle. Another occur was when I was launching my boat into the lake. I was backing up and lost brake pressure and had to apply my emergency parking brake to stop my truck from going into the water. This vehicle has been checked by 2 different dealers, 4 different times in the past year. I do not feel safe driving this vehicle. The date listed below was the last occurrence when this happened. (not the prior 5 occurrences)
Total brake failure. The pedal became hard as a rock with no advance warning. I received a notice (n182202780) from gm stating that I might experience increased brake pedal effort. It went on to say how this notice "is not a reacall" and that brakes still meets "all federal motor vehicle safety standards for brake performance" I'm writing to bring attention to the fact that my truck experienced no symptoms of a problem until the pedal had maybe 10% assist. No check engine light or notice from the drivers info center. I applied the brake, shifted into drive, accelerated then applied the brake to stop and maybe had 10% braking ability. The notice also went on to say that "failure to follow recommended oil change intervals could contribute to this condition". The truck has 32000 miles on it, I've owned it since new, I have always changes oil with 20% life left in it. This is about 2000 mile sooner than the manufacturer recommends. This is a very serious condition that gm has recognized in there letter, but in my opinion, are not taking it serious enough. Unless I'm a "one off" case, this will very likely get people hurt and property damage if not addressed very soon. Please look into this, thank you
Stopped at a stoplight, no problem. After a few seconds truck started to roll forward. Had to apply tremendous pressure on brake to stop vehicle. Problem continued until I was arrived at destination a quarter mile away. Occurred several more times. Cut vehicle off and when restarted it occurred once and then returned to normal operation.
Tl* the contact owns a 2017 gmc sierra 1500. The contact stated that while attempting to brake, the brake pedal was stiff and very difficult to depress. The contact mentioned that the ABS in the brakes was vibrating. The vehicle was not taken to a dealer or independent mechanic for diagnosis or repairs. The manufacturer was notified of the failure. The approximate failure mileage was 32,000.
Vacuum pump, brake pedal stiff when reversing, hard to stop.
The brake pedal becomes extremely stiff when trying to stop at slow speeds, especially in parking lots. The vehicle becomes very difficult to stop almost causing crashes. Gm dealership repeatedly tests vehicle and tries to claim there is nothing wrong and I'm making a mistake. Had to take vehicle in several times and eventually they found a failed vacuum pump. They tried to make me pay $700+ for the repair even though its a known issue. They are trying to avoid doing a recall and putting their bottom line ahead of safety. These trucks are dangerous.
The brakes are not working at slow speeds. I was parking in a parking garage while pulling up to the concrete wall and pushing on the brake the truck almost didn't stop and the pedal got very stiff. While driving home in traffic the truck did the same thing and I almost hit the car in front of me. It seems to be at slower speeds and the brakes are losing all power. The truck is only 2 years old and normally stops on a dime. Took to the dealer today, and they said the vacuum pump is bad at only 39,000 miles.
