Brake pedal becomes very hard to push at low speed, almost unable to stop the truck most times. Happens on a daily basis

- Carrollton, OH, USA

Brakes become very difficult to depress after 2-3 depressions of the pedal. Happens mostly in parking lots and stop/go traffic. Driver must apply great pressure to slow/stop vehicle.

- Virginia Beach, VA, USA

Driving around parking lots or stuck in traffic going slow and having to press the brake pedal frequently the pedal will go very hard and takes both feet to press down on it and basically have no brakes. I have I to pull over or stop and shut the truck off and sit for a min then restart and I get my brakes back. I think it has something to do with the vacuum assist pump not working correctly. I have not taken in to the shop yet cause I'm out of the bumper to bumper warranty

- Macon, GA, USA

Reoccurring braking problems at low speeds whenever pressure is applied to the brake in quick succession (ie bumper to bumper traffic) the brake pedal becomes harder/stiffer to press and applies little to no brake without excessive force. I have only noticed this braking problem at low speeds because of the conditions that cause the problem. This happens when the vehicle is driving straight as well as turning. The vehicle also make a sound as if the ABS system is activating and the brake pedal feels as though the ABS system is activating. No lights illuminated on the dashboard during the braking. My vehicle only has about 50K miles. The vehicle was also bought from a certified Chevrolet dealer

- Lisbon Falls, ME, USA

I was driveing the vehical pulling a boat on a trailer coming up to a stop sign, I then went to press the brake and the pedal was hard and the truck wouldnt stop. It was very difficult to press the brake and if my wife had been driving im not sure she would have had the stregth to press the brake and stop the truck. This is a very dangerous issue. Took the truck to the dealer and they said that the vacumm pump had failed and needed to be replace along with the vacumm hoses and the brake booster. The dealer wanted $1400 to replace these components on a two year old truck. I replaced all the components with factory parts.

- Gloucester, VA, USA

Brakes barely work at low speed and require a lot of pressure to get the vehicle to stop. Nearly backed my truck into a lake while backing down a boat launch. Very dangerous! there are so may complaints on this issue and the NHTSA has been "investigating" it for over 6 months now. When will something be done?

- Portage, MI, USA

Unresponsive brakes at low speed. Very dangerous and not sure why this isnt a recall. How many people have to get injured or die before its fixed?

- Clermont, FL, USA

The brakes went stiff and my wife was barely able to get the truck to stop. This was luckily just backing out of our drive way. It could have been really bad if she was going faster or needed to stop quick.

- Santaquin, UT, USA

When applied brake pedal was very difficult to push down and brakes did not function properly. Vehicle was in motion on a city street at time of incident. Took to Chevrolet dealership and they told me it was a bad brake booster and that they have had a lot of trouble with them.

- Nevada, MO, USA

On the date cited, I was backing up a trailer down a hill slowly. Had released the brakes then reapplied and suddenly the brake pedal was stiff and it was very hard to stop. Manually applied full strength trailer brakes and the trailer helped stop the truck. 3 days later (5/30/19) I experienced a similar incident. I was parked, put the truck in drive accidentally and took my foot off the brake. When I applied the brake again quickly to switch to reverse, the pedal was extremely stiff. Nearly hit the vehicle in front of me. Put into reverse and no issue. At no point was a "service brake assist" message displayed as noted in a 'special warranty' letter received from GM in the mail between the incidents. No other error codes or messages were displayed. 2 years ago after having towed a trailer, the message "service brake assist" was displayed on the screen once, the local service dealer pulled codes and did not perform any repair.

- Cedar Rapids, IA, USA

April 2019 letter from GM saying my brakes could possibly loose their vacuum assist. They do not want to fix the problem unless I have problems and extended the warranty to 6 years and 72,000. What a cop out, what if my brakes do not work properly in a tight stopping situation? I have attached a copy of the letter, please do not let GM play with our safety on a $52,000 vehicle or any vehicle.
