Brakes Failed problems of the 2016 GMC Sierra 1500

Brakes fail. Will not allow vehicle to come to a complete stop when going forward or in reverse. When accelerating vehicle violently shakes. This happens at any speed above 20mph.

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!!.

At low speed the brakes become hard to stop the vehicle and in reverse the brake pedal become hard and becomes very difficult to stop truck the truck was in a drive through and almost hit anouther car due to brakes failing a service brake booster soon warning came on.

While transiting on a major highway in north florida the traffic came to a sudden stop and unfortunately when I pressed the brake pedal nothing happened, I had to push the peddle with extreme power and it still was not enough. To avoid the slower vehicles I had to pull the truck onto the grassy median to avoid a possible deadly collision. I was able to recover control of the truck thankfully. Mysteriously the brakes worked again when I came back onto the highway. I took the truck to a nearby GMC service dealer and after the truck was tested they informed me that they found a faulty brake vacuum pump. In discussion with the dealer they also informed me that this is becoming a "somewhat common" issue. Without warning or any indicator the brake system failed, this is completely unacceptable. Lives could have easily been lost due to a malfunction part. Vehicle only had 27k miles on it.

Tl-the contact owns a 2016 GMC Sierra 1500. The contact stated that the brake failed, when the contact drove at low speed and engaged the brake pedal the vehicle did not stop on a timely manner, the contact had to depressed the brake pedal several times to bring the vehicle to a stop. The vehicle was taken to ron anderson Chevrolet Buick GMC dealer 464054 e state road yulee FL, 32097 phone number (904) 572-4132. The dealer performed a diagnostic that located the failure at the brake vacuum pump. The brake vacuum pump needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was 41,000. Li.

Tl- the contact owns a 2016 GMC Sierra 1500. The contact stated that within less than a week of owning the vehicle while exiting the parking area of the dealership corwin cdjr fiat, 2445, 1025 w sunshine st, springfield, mo 65807, (417) 862-9272 was informed verbatim that when the brake pedal was applied that it was extremely hard and failed to depress. The vehicle was not serviced yet, was unable to be safely driven due to the brake failure and the dealership stated that the vehicle may be serviced for a warranty but it may not be in effect for another 60 days. They stated that the vehicle may be serviced for TSB pit-5361b (additional brake pedal effort) but had not yet specified the manufacturers guidelines to determine a remedy and replacement part. The vehicle was not repaired yet. 29 TSB had been issued for the brake system however no brake system recall so the contact was uncertain of the vehicle may be repaired by the dealership. The approximate failure mielage was 71,000. Dyd.

2016 GMC sierra- bought used hard shifting noted immediately and shuttering on inclines, took to dealership had part replaced- fixed shuttering but not hard shifts- now it not only shifts hard but while I was trying to stop at a drive through the brakes failed- lunges forward almost hitting the car in front of us- next day I pulled into a parking spot same thing happened- brakes would not compress- stood on the brake before it finally stopped- backed up a bit to straighten up and the damn thing did it again in reverse. I'm traveling back home to arkansas from florida in a few days with my children and I'm scared to death to drive this thing. I can't get it looked at before we leave because of the weekend/ christmas break. Seriously unsafe vehicle! there should be recalls on these vehicles! I've read so many similar stories, why has this not been addressed yet? GMC should be ashamed.

On multiple occasions, the brakes appeared to loose all brake booster function, causing incredibly weak braking at low speeds. Twice it failed in a parking lot situation, where the effect was minimal (just required pushing the pedal with maximum force I could generate) the most recent was a parallel parking situation where the brake failure almost cased a low speed collision. I missed the car behind me by mere inches!! I address this with the gm dealer twice and both times I received "could not duplicate" it will be noted again. This needs to be addressed via a recall as it is a major safety issue, and is not specific to my truck (this has been documented on the internet, and there is a TSB for it which mine supposedly was not part of) the problem is low speed, at idle manuvers where the brakes are replied repeatedly (like parking). I never noticed a problem at any speed above crawl.

Brake failure - multiple time while driving my 2016 GMC sierra, the pedal has gotten hard & will not stop the car. This generally happens after using the brakes several times quickly. The brake pedal will get hard & the truck will not stop. Luckily I have not been injured but the problem is very dangerous & I fear for my life while driving this truck. There is a technical service bulletin on the problem, TSB # pit5361c, however it is not a safety recall. How many people have to die before the NHTSA enforces a recall?.

Had to replace vacuume pump after intermittent brake failure at slow speeds with only 38,000 miles on the truck. Brake failure would occur without warning. Dealership diagnosed the issue after testing he vacuume pump, which was reading 6 psi. Was told there have been no recalls for this issue.

When braking at low speeds, especially in reverse, brakes fail. I have to push the pedal all the way to the floor and they still do not operate correctly. This is a consistent, multi-incident, problem since purchase. Manifests especially when backing into a parking spot.
