The brake line in the middle of the car broke because it's rusty, and all brake fluid is out, vehicle not braking
- Matthews , NC, USA
2017 GMC Sierra K1500 with 59, xxx miles. Recently noted braking issues with vehicle in parking lots or at slower speeds. The brakes are difficult to engage. I do not notice this issue when driving at higher speeds. On 3/27/23, I backed the vehicle out of my driveway and had a near miss collision as it was very difficult to engage the brakes and stop the vehicle. After the near miss, the brakes, calipers, and rotors were inspected and all were in good working condition. I contacted the dealership where the vehicle was purchased. The representative from the dealership informed me that this braking issue was addressed as a previous recall for N192268490 ZPSR (Product Safety Recall) on 5/24/21. On 5/24/21, I took the truck into the dealership for another issue and this recall was addressed at the same time. I was not having any issues with the brakes at that time. The representative informed me that the recall was closed on the truck, and they now charge $200/hr if I want to bring the vehicle in for service. The current braking issues appear directly related to the reported braking recall issue that was reportedly repaired on 5/24/21. The vehicle is not safe to drive and would appreciate assistance from the NHTSA to safely resolve the issue.

There has been a recall on the assisted braking pump. My truck is not on that recall as of now. But I am having the same braking trouble at slow speeds. Is there any way the company will fix this issue.

Trailer Brake System Fault requiring service. Seems like its an issue a lot with Chevy and GMC Trucks.
- Wasilla, AK, USA
The trailer brake system is displaying a warning. The truck has less than 50,000 miles and the tow option has never been used. I am told that it would be risky to use it without repair. this is a safety issue that should be a recall. I have checked and there are thousands with the same issue and it has gone on for years without being addressed by GM or NHTSA. It's time to step up and take care of this situation. There is no telling how many have been injured or killed by this. if nothing is done I will approach someone in the media.

While parking I was backing up to straighten the truck in the space. When I went to stop I noticed that "normal" pedal pressure was not stopping the truck and I could tell vacuum was not available to boost the brakes, causing me to have to "stand on the pedal", almost causing me to hit the car behind me. I purchased the truck used four months ago and when checking recalls the nhtsa says none are open so I assume it has been addressed but didn't fix the issue obviously.

I was pulling in to a parking spot and pressed the brakes and the truck didn-??t stop and I hit the sign. When I looked at the dash there was a -??service brake assist -?? warning on.

I am experiencing hard brake pedal and/or brake fade when attempting to apply the brakes. Their is a recall for this problem on other models, however my truck model year is not included for some reason. This has occurred on multiple occasions and has nearly caused an accident on those occasions. My truck also began to roll out of a parking spot and I had extremely hard brake pressure but no response from the brakes.

My 2017 GMC Sierra is experiencing similar issues with excessive force required, vibration in brake pedal at low speeds, and delays in stopping as found on 2018 and up trucks and SUVs. I notified the dealership about a year ago about the issue and it potentially being linked to the recall and they said it wasn't and they would have to charge me to inspect and repair. The issue can obviously lead to an accident if the brakes continue to worsen and fail. Also abrupt stopping at low speeds doesn't work efficiently putting anyone who steps out in front of my vehicle or stops abruptly in front of me at risk. A couple of times there was a diagnostics alert sent to my email stating an "issue with the antilock braking system was detected". There are already accidents reported with 2018 and up vehicles because of this issue. I feel the recall for the 2018 and up vehicles needs to be extended to 2017 vehicles to prevent accidents.

When pressing the brakes a few time at a low speed Iose brake power. There is already a recall out for this model but not my vin. This is my recall issue Brake Assist Decreased Due to Vacuum Loss

I purchased my vehicle in January 2022. On 11/18/22 I captured a photo across my dash stating that the trailer brake system needed to be serviced (photo attached). This was the second time this message appeared within days. The vehicle continued to beep and flash for a long period of time clearing out my dash screen making it UNSAFE TO DRIVE. The beeping noise startled me, almost causing an accident on the freeway. I did not know what the warning meant as I wasn't towing a trailer. I wasn't towing anything and could not turn off the beeping sound or the flashing screen, in spite of hitting the dismiss button. I don't know why the message continued to go on and assuming there is an electrical shortage somewhere with the wiring. This needs to be recalled and fixed as it is a manufacturer issue. I do not have any aftermarket parts installed in this vehicle. This same alert message appeared again yesterday 12/5/22 as I was driving back from the airport. It continued for almost 2 hours while on the freeway and again I was not pulling or towing anything. I pulled over, checked my tailgate, turned off the vehicle and turned it back on and the message continued until I got home. It is very alarming and annoying and scared me. This is a big safety hazard and almost caused an accident again as the alert is very loud and flashes across, clearing out your screen, causing you to take your eyes off traffic looking ahead. This time, I was traveling in heavy traffic. Please investigate this further. Thank you

The service message appeared on the display after backing up "SERVICE BRAKE ASSIST" I searched this issue and found over 65 complaints for this vehicle year/make /model. I am at work and fear driving home as this issue has resulted in brake failure on some of the complaints noted. I have not contacted anyone yet, I wanted a recall notice as this is a safety issue and we cannot afford any costly vehicle repairs.

Hi I purchased this used 2017 GMC Sierra Denali on October of 2021 it-??s been just only one year and while on the road with my trailer attached, I suddenly got a pop up on my display saying -??service trailer brake system -?? which caused me to be distracted with the chime and the warning being displayed repeatedly and overall left me with no power at all to my trailer brakes I would like to have this recalled and fixed at little to no cost due to the fact of the cheap and unsafe parts that are installed on these types of trucks by GMC

Trailer brake system error comes on. I dont even own a trailer or have ever towed a trailer. It cuts power momentarily and is very very unsafe. Please fix before someone gets hurt.
- Barrington, IL, USA
A Service "Trailer Brake System" message keeps coming up on my display constantly, over and over and over, I can't see the speed display, I can't hear the turn signal sound, it's extremally distracting and loud. When I looked this message up I found the wiring was faulty and my trailer brakes won't work.
