I am experiencing an issue with a hard brake pedal on my 2014 GMC Sierra 1500. This same issue was previously addressed through a recall and special coverage program by GM, which I had performed. However, the hard brake pedal condition has returned, significantly impairing stopping power at low speeds. This poses a serious safety risk, especially when towing or parking. I can no longer park my trailer safely. The vehicle is difficult to stop, and braking distance has increased substantially. This is a known issue with this model and year. It appears the prior recall may not have adequately resolved the root cause. I am requesting that the federal safety agency investigate whether additional action or recall extensions are warranted.

What owners say
Says I have no recalls. I have terrible gas smell and steering light abs light traction light abs light and hard brake pedal. Seats and mirrors move by there selves. Steering wheel shakes. Overall this truck is worrying me so much I won't put my kids in it. Oh also airbag light on also.
I have a hard brake pedal and reduced brake responsiveness.
At slow speeds brake pedal is hard to push and does not stop the vehicle. Almost caused multiple accidents at intersections not being able to stop vehicle from going out into traffic. Doing research this has happened on multiple gm vehicles from 2014.
My vehicle brakes become spongy or pedal goes all the way in and vehicle will struggle to stop at low speeds. Such as when I pull into a parking space or backing up.
Excessive hard brake pedal when driving at lower speed, almost got in accident while in traffic due to truck pedal getting hard and truck would not brake. It only happens al low speed or driving in parkinglots.
Two different times being at low speed almost a roll. Went to apply brakes and truck barley stopped. Hard brake pedal, brake pedal to the floor. Once on a highway in extreme heavy traffic on a down hill. Second time rolling making a turn to park in a parking lot and almost struck police car and a gas pump.
Hard brake pedal at low speeds. Forward or reverse
Brake pedal became hard and was difficult to stop properly. I felt that I had no control over this vehicle. .I brought the truck to vail gmc in mt kisco ,ny on sept 22, 2017 they said it was the vacuum pump and had to be replaced at the cost of $353.16. The vehicle only had 40256 miles on it just out of warranty. It was brought to my attention that this a real problem with this issue nationally. This is a potentially a dangerous condition and is unsafe.this braking problem was on the the city street and parking lot.
Tried to stop tuck when parking. Brakes were extremely hard and truck came to a slow stop while I was mashing the breaks with all my might. There was break fluid all around right front tire. Dealership found engine oil in vacuum line of vacuum pump due to valve stuck in pump causing hard brake pedal. Replaced vacuum pump, pipe, brake booster and master cylinder, fluid.
Hard brake pedal at low speeds causing the truck to not stop. Dealership says a full brake system replacement is needed. I've serached online and there are several people having this same issue. It seems to be very common, but nothing is being done about it by gmc.
