We want to report a safety feature in 2015 gmc sierra 1500. We bought a vehicle brand new and it currently has about 40,000 miles on the odometer. On 11/4/2017 after we got off the interstate 10, the break from this truck stopped working, we had a difficult and dangerous time to make it stop, and was lucky to manage to get into a store's parking. We have to haul it to the local gmc on monday and found out the break…

Out of no where, i had to use extreme pressure on the pedal to stop the truck. The brakes began to sound rough. I turned the truck on and off hoping that would fix the problem. It didn't, i took it into my gmc dealer to find out that the vacuum pump has failed for the brakes. I did my research online and noticed many people have had the same issue. I was surprised there isn't a recall on 2014-2016 gm vehicles. This…

Vehicle loses brake pressure while moving at slower speeds. Once coming to a stop, then doing slow speed stops and starts the pedal will become hard and requires great effort to bring the vehicle to a complete stop. Issue started at about 38,000 miles just after factory 36,000 mile warranty. Issue presents itself more often in reverse while backing in, especially if grade is sloped. Have had multiple close calls in…

2015 gmc sierra - braking becomes very difficult at idle speed whether moving forward or reverse. Brake pedal becomes very difficult to depress. Vehicle will move a few feet until completely stopped even with forceful pressure on the brake pedal. Appears to lose all vacuum/power braking ability.

Brake pedal does not depress easily at low speeds. Extream effort is required to push brake pedal enough to get vehicle to stop.

At 47,000 miles. I noticed a slight vibration in the front end while braking on the highway. Over the next 2 weeks the vibration became considerable worse. It felt as though the rotors became warped which i have experienced during vehicle testing at previous employments. I replaced the front brake rotors and brake pads. During removal of the old brakes, i quickly noticed that 1 of the 4 pads was completely corroded…

Backing boat down boat ramp (not a steep ramp) in trailer mode, braking did not stop vehicle. Pumped pedal several times, used lots of force on pedal. Because of slow speed and increased effort, the vehicle did stop. Pulled forward and repeated at slower reverse speed and same poor braking. Dry conditions, brakes dry, did not put rear wheels in water. Have not had a repeated event. Dealer indicated that service…

On 2/5/2017 while turning unto my street the steering wheel locked and i could not move my truck from hitting a block wall. I also tried breaking but the car did not stop in time to not hit the wall. I was driving slowly (20 mph) because i was in a neighborhood and me and my family were all wearing seatbelts so no one was seriously injured. The airbags did not deploy at all. And i also bent the steering wheel in…

Brakes do not work when in reverse or at low speeds. Problem was there the day i purchased the vehicle. A couple weeks after purchase i backed into vehicle in a parking lot. I was told it was "normal" after almost having a wreck i did some research. How is this not nationally advertised as a recall yet? This is a huge safety negligence on gmc's part. The vacuum pump is known to fail by every dealer i have called.…

Having issues with hard brake pedal. It happened a few time when the truck was new but could never duplicate it. Twice it almost caused an accident. I have since found a way to duplicate it. When backing a boat trailer down a ramp every time they become hard, i have to ride the emergency brake, but it only happens when the boat is on the trailer. I have researched this over the years but not till recently have i…
