2016 GMC Sierra 1500: brake failure

Filed Jan 12, 2026 · Brakes · ME

While traveling at low speeds in parking lots and in the operation of parking, my 2016 GMC Sierra 1500 gets a hard brake pedal that goes to the floor but I have no brakes. I almost hit a person in a local grocery store parking lot, at the bank driving up to the ATM, and I almost lost my truck over a bank because the brakes failed. This has happened multiple times at low speeds but it is getting more consistent recently. It has endangered myself and others. It is only a matter of time until damage occurs or someone gets hurt.

I towed a trailer last month and noticed some hard breaking issues in slow moving traffic. Las night as I was parking my vehicle under the car port, I had to press on the brakes to straighten my vehicle and as I was moving forwards slowly, my brakes failed, the pedal was stiff and I almost hit my other vehicle and the garage door.

2 times now my truck brakes did not work. I mean, they literally didnt work. The first time it happened my pickup almost hit my house. The second time it happened the pickup hit another vehicle at my home causing damage to both vehicles. I am currently in fear of driving this pickup truck do to these 2 brake failures. Will the next crash actually hurt someone? Gmc needs to repair these brake failure issues. Again, there was absolutely no brakes even though I pressed on the brake pedal as hard as I could. The property damage amount from the second brake failure is well over $2,000.00. Please have gmc repair/fix this problem so I can drive my pickup without worry and more damage.

Brakes had already been repaired by dealer under recall prior to this incident. For several weeks I noticed problems. The hill assist would not hold even when braking the truck rolled back on hills. The petal would feel hard like something was keeping it from depressing. Finally, the brakes failed again while I was in line at a fast food restaurant. One second they worked, the next they did not! I was moving slowly and able to put it in park. Got out and asked for help moving it out of line and into a parking spot. I put it back in gear once people had stopped cross traffic and rolled slowly into a parking spot. Approaching the light pole, I depressed the brake again and it would not depress. There was a scraping sound and I pumped them several times, but it didn't feel like there was any give at all. I rolled to curb and put into park. I had the truck towed to dealer, traded it for another car and never drive again. Date was november 15, 2019. 8:30 am. The truck had approximately 50,750 miles on it. Very scary and dangerous as there were many pedestrians including children in parking lot and using crosswalk which transects drive lane. This problem was supposed to have been fixed at dealer just a few weeks before, so fix obviously did not work!!

I was on my way back from a beach vacation saturday, june 29, 2019 along with two other vehicles driven by other family members. I drive a 2016 sierra 1500 slt with 30,000 miles on it. After driving for 1 1/2 hours with many opportunities to use my brakes, our convoy needed to make a stop to turn left. To my great surprise the power assist was not working. At first I thought I had no brakes at all. I pressed hard with both feet and stopped the truck before I rear ended my son in law and his family. Scared me to death!! I phoned ahead to our lead car and told them I had serious vehicle problems. There's no way I could drive 400 miles with heavy traffic safely. We searched for the nearest gm dealer and selected j. M.jackson in andalusia, al. Even though it was a saturday, the sales people called the service manager who came in along with a service tech. Shorty I had a new vacuum pump installed and there was no charge since gm had issued a service bulletin. But now I'm worried about another failure. I barely avoided an accident this time. There was absolutely no warning prior to failure . After the initial failure to brake properly, I got a service brake assist message. Very dangerous failure. A crash was narrowly averted.

Brakes failed completely at low to moderate speeds both going forward and in reverse. Brake pedal went flat to the floor and the vehicle failed to stop. Initially occurred november 7, 2018 and has periodically recurred since then. As of march and april 2019 it has begun to recur more frequently. After the initial occurrence I took the vehicle immediately to the dealer. They could not replicate the problem and took no corrective action. They did recommend replacing the front brake pads and machining the rotors, which I had them do. Mileage was 44,522 at that time. It is back with the dealer today and the focus seems to be the brake vacuum pump. Of course, the vehicle is now out of warranty so I'm waiting to see if they will perform the repairs at gmc's expense or not. If not, I will likely begin contacting other owners to create a group large enough to initiate a class action lawsuit.
