At low speeds I have no brakes.

- West Jordan, UT, USA

The incident occurred on [XXX]. My vehicle has 54,571 miles on it. The power brake assist function failed. I was backing into a parking space at a local fast food chain and experienced near brake failure. I had to stand, nearly full body weight pressure, on the brake pedal to get my truck to stop at very slow speed. I, again, backed a short distance of a couple of feet at the most and experienced the same issue when I tried to stop. I placed the vehicle in PARK and turned the engine and ignition key off, thinking the system possibly needed to reset. I started the truck and drove forward, very slowly, to another parking space and applied the brakes. I experienced near total brake failure again. I had my truck into Brogden GMC in Olathe, Kansas on [XXX], for general maintenance and a -??brake pressure recall.-?? I had experienced a slight brake pressure issue on a couple of occasions prior to the recall. After the recall service was performed I did not experience a braking concern for some time. I did experience -??soft braking-?? a couple of times after the recall was performed and attributed it worn brakes. On [XXX], at 50,596 miles, I upgraded my brakes by installing a Power Stop Z36 brake kit with slotted rotors and ceramic pads. I have not had a repeated experience of soft braking or brake failure until the [XXX] incident that I am currently reporting. It appears to me that the earlier recall did not completely address the brake failure issue with my 2017 GMC Sierra 1500 pick-up.

It takes quite the amount of force to stop the vehicle brake pedal started feeling spongy and seems like it doesn-??t have enough pressure constantly I have no brake fluid leaks or air in my lines it all comes down to the brake booster it seems like and I know a few vehicles had this problem but mine says it wasn-??t but I believe it has been affected.

Service Trailer Brake System. This has happened in the past 3 Times, in which the local GMC Dealership has made me pay for New Batteries and other Fuel system issues. Dealership stated that this shows up because of a bad battery.

At low speeds the brake pedal gets hard and it feels like the antilock brake system is activating, I believe this is the issue with the Brake booster vacuum pump. GM isn't calling this a safety issue.

I turned it on the info system on dash told me to roll down and then roll up window. Husband when driving noticed barking issues - really having to pump brakes (week before) We looked up recalls they are there for both issues for my year make but I have a bigger engine that the recall states so I am not covered yet it is doing all that same stuff for the recall which my husband put it what the truck was doing and found recalls just not for our engine size- THIS TRUCK IS NOT SAFE TO DRIVE AS WHEN YOU TURN IT WILL SHUT OFF IMMEDIATELY.

Brakes intermittently quit working at slow speeds. Sometimes while pushing on the brake pedal, the brakes don't respond, I have to increase the force placed on brake pedal. There is also a pulsating sensation at the pedal like the ABS is being applied, even though I am traveling at slow speeds, and it takes much longer to stop the vehicle. There are no warning lights that come on and there is nothing on the message center stating there is an issue. Has happened multiple time, usually in a parking lot, or in stop and go traffic. Also has happened when vehicle is in Reverse. Have never had the issue at highway speeds.

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.
