When I am braking at low speed my brakes start locking up and eventually do not work. This has happened on multiple occasions. I have almost wrecked multiple times I rarely drive my truck now cause it is unsafe. There is a recall on the brake booster 2014 to 2018 gmc seria but my truck vin is not included on that recall and it-??s doing the exact same thing. GM recalls 3.4 million pickups and SUVs over brake pump Sept. 12, 2019 1 The recall includes the Chevy Silverado and GMC Sierra (model years 2014-2018), and affects a vacuum pump defect that may make it more difficult to brake at low speeds.

Noticed that there was a recall on this vehicle NHTSA Campaign Number: 19V645000. My concern is that I took my vehicle in back in 2018/2019 for this repair. However my vehicle vacuum pump completely failed the other day where I cannot brake. My vehicle is only at 70,800 and fail to see that if a proper repair was completed back in 2018/2019 for it to fail again a couple of years later with low mileage. While I was able to get this vehicle home safely my concern is that if it failed earlier in the day on the highway I may have cause a serious incident.

Going under 15mph, applying the brake causes the pedal to become stiff and lock up and not work. This has caused me to almost hit someone in traffic. I immediately got off the road and got my vehicle to a safe location off the road. Communicating with a dealer today to confirm possible recall issue or potential repairs.

At low speeds excessive brake pressure is required to stop my truck. Other GM trucks have been recalled for this issue, but i am told my vehicle is not included.

At low speed and idle, brakes lose power and pedal becomes hard to push. Once RPMs increase, brakes regain full use.

"Service Trailer Brake System" alert on dash. This is a safety concern for 2 reasons; the first being the chime made to warn the driver is distracting, persistent, and annoying. The second is the trailer brake system is apparently not functioning properly which is a danger while towing. This is not the first time this has happened and is a danger to me, my family, and other on the road.

Whenever driving I get a message stating that I need to service my trailer brake system. This is most likely due to cheap wiring installed by the manufacture. This has been going on for over a couple of months. Just recently, I was making a slow turn and my vehicle shut off on me and I lost control of my brakes and steering and all power to the vehicle which is a huge safety concern and I am unsure if they are related or not

Hello, I am driving a 2014 Sierra truck with 17,761 miles, my father-??s work truck. The first week I had No problems, the 2nd week the Trailer Brake warning came on relentlessly. New truck, scary Warning sign! I took it to GMC to dislocate trailer brake, they sold me a $340 trailer brake control switch. Upon my return to where I live a loud sound came from when I was idling to wait for construction to accelerating. I noticed once I got home, my back wheels were hot and a burning smell! I hate when you take your car in for one warning sign and you get something so much worst and you paid outrageously for that! Karma!

I was driving my truck when the Brake assist light came on. When applied the brakes they started pulsing and grabbing. I took it in for service and was told that the Electronic Brake Control Module needed to be replaced and the brake fluid flushed.

I-??m having a trail break system warning every few minutes. It is constant and beeps consistently. To the point where I almost cannot drive it. It won-??t go away after a little while and is constantly turning on and off. This just recently occurred and hasn-??t stopped since. Likewise there was no other indication of this happening till about two days ago. It-??s very distracting and persistent to the point where I feel like I can-??t even drive with it on.

Driving at certain speeds the truck will just shut off while trying to turn or merge onto the highway. The electronic steering draws to much voltage on the vehicle and it just dies turning and braking after that is a very serious safety hazard and should be looked into I-??m a mechanic myself and I-??ve replaced grounds done everything I can and still nothing has fixed the issue
