2017 GMC Sierra 1500 Brakes

The contact owns a 2017 GMC Sierra 1500. The contact stated while driving approximately 30 MPH, he heard an abnormal noise and while depressing on the brake pedal, the vehicle failed to decelerate. The contact stated no warning light was illuminated. The contact was able to cruise to the side of the roadway until the vehicle decelerated. The contact stated he shifted into reverse to stop the vehicle completely, before shifting into park. The vehicle was not drivable. The contact towed the vehicle to his residence. The contact stated he had an independent mechanic come to his residence and he was informed that the brake caliper and the front passenger’s side brake pads needed to be replaced. The vehicle was not repaired but was pending repairs. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had been informed of the failure. The failure mileage was 53,579.

The brakes are failing especially after braking while on an incline . Pressure on the pedal becomes mushy then hard and will not stop the vehicle. The truck has 90,000 miles on it. A brake assist light came on while backing down a hill and braking .

Leaving a parking lot and had a complete loss of brakes due to faulty vacuum pump.

A Service "Trailer Brake System" message keeps coming up on my display constantly, over and over and over, I can't see the speed display, I can't hear the turn signal sound, it's extremally distracting and loud. When I looked this message up I found the wiring was faulty and my trailer brakes won't work.

Loss of power assist at slow speed when backing or going forward. This has happened several times since I have had the vehicle. Brake pedal is very hard to press and vibrates.

EBCM needs to be reprogrammed. Larry Stovesand GMC in Paducah, KY will NOT service my recall because it was closed on 2019, research has shown that this programming may need to be done again. After telling them this info. they are now saying that they will not service my recall because it has a salvaged title. After researching how a salvaged title is still honorable for a free recall service they are now telling me to take it somewhere else.

Driving on the highway going approximately 64mph and the traffic lane shifted over and everyone started to slow down and when I went to apply some brake . The pedal got very hard and became very hard to push down effecting my ability to brake properly. This almost caused me to get into an accident and I had to shoot over to the breakdown lane giving me enough time to slow down. My pedal became very hard to push down. This problem continued throughout my travel and service brake assist came on after the fact

Still having the slow parking problem. Almost hit a car today when trying to stop while parking truck. Software update by dealer did not fix the problem. This happens every time I try to park and/or slow stopping at a crosswalk.

Brakes have stopped working while driving down the road, previously they have occasionally glitches out primarily for example when I pull into a drive through restaurant or in a parking area. Service Brake Assist pops up.

Hi I purchased this used 2017 GMC Sierra Denali on October of 2021 it’s been just only one year and while on the road with my trailer attached , I suddenly got a pop up on my display saying “service trailer brake system “ which caused me to be distracted with the chime and the warning being displayed repeatedly and overall left me with no power at all to my trailer brakes I would like to have this recalled and fixed at little to no cost due to the fact of the cheap and unsafe parts that are installed on these types of trucks by GMC

WHEN I APPLY THE BRAKES IT DOESN'T WANT TO STOP AND I HAVE TO PUSH IT DOWN AGAIN ALMOST LIKE THERE IS A ISSUE WITH THE VACUUM ON THE BRAKES BUT IT SAYS MY VEHICLE IS NOT AFFECTED BY THE RECALL BUT THE SYMPTOMS ARE EXACTLY THE SAME AS THE RECALL.

While backing up I hit the brakes and the pedal made a clicking noise. I pumped the brakes and it stopped. This has happen several times over the past several months. I made a compliant to the dealer while under warranty and they found nothing wrong. 62000 current miles on the vehicle. Safety issue???

While in a parking lot, I tried to slowly move forward and then come to a pause. My brakes didn't work quite right and the vehicle didn't stop for an additional 15-20 feet from where I would have liked to stop. Luckily I was just moving forward to get out of the way of another vehicle trying to drive behind me and I didn't have anything directly in front of me that I needed to stop before. If I was trying to stop for a pedestrian I would have certainly hit them. If I was trying to stop behind a vehicle who suddenly stopped I would have ran into the back of their vehicle. There has been a recall on similar vehicles; same make, model and year as mine for what appears to be the same issue. Recall # 19V645000 This has also happened in my garage while pulling in, and in another parking situation. The Service Brake Assist warning comes on the Information screen.

I was backing my boat into the water at a boat ramp and my brakes got very hard to push when I was backing into the water. I had to stand on the brakes to get it to stop, if my wife had been backing the truck in, it would have been in the lake. I see that there are no recalls on this vehicle. I bought it about four months ago and don't know the history of any recalls that have been done. I also had the transmission problem with the shimmy, and per the GM dealer flushed the fluid and the shimmy has all but disappeared. I am glad, because when I ask if it didn't repair it would the transmission be covered under warranty, he said no because of the mileage. These reasons are probably why the guy traded it in in the first place.

THIS HAPPENED MULTIPLE TIMES. THE BRAKE PEDAL IS HARD AT LOW IDLE, AND YOU HAVE TO STAND ON BRAKE PEDAL TO STOP THE VEHICLE. TYPICALLY HAPPENS WHEN TRYING TO BACK IN A PARKING SPOT OR IN STOP & GO TRAFFIC THE BRAKE PEDAL BECOMES HARD TO PUSH AND TRUCK DOESN'T STOP AS QUICKLY

Stiff brake pedal at low speeds and brake assist error message

LOW SPEED BRAKING ISSUE. WAS IN A PARKING LOT TRYING TO PARK MOVING ABOUT 1 OR 2 MPH. TRUCK WOULD NOT STOP AND IT WAS LIKE THERE WHERE NO BRAKES UNTIL I PRESSED AS HARD AS I COULD. DOES NOT DO THIS AT NORMAL SPEEDS

My brake pedal randomly gets extremely hard, causing my truck to not be able to stop as it should. This almost caused me to read end the vehicle in front putting everyone in danger. There are no warning lights on. There is a recall for this issue that my model year falls under however my vin says no open recalls. It’s a booster vacuum seal problem with the breaks. Very frustrating that my truck is experiencing this recall issue but is not included. This causes a huge safety issue.

ON 9/2019 THEY SUPPOSEDLY DID THE REPROGRAM TO FIX THE HYDRAULIC BRAKING ISSUE ON MY TRUCK. IT IS NOW DOING THE VERY SAME ISSUE AGAIN. I GO TO SLOW DOWN OR STOP AND FEEL LIKE ITS NOT SLOWING DOWN AND I PUMP THE PEDAL TO GET A GOOD PEDAL TO STOP. IT DOES THIS QUITE FREQUENT NOW. IS THERE ANYONE WHO CAN HELP ME SEE IF THIS CAN BE DONE AGAIN UNDER RECALL?

GMC SIERRA WAS BROUGHT TO DEALER FOR EXISTING RECALL REGARDING BRAKING. DEALER INDICATED RECALL HAD BEEN RESOLVED. WHILE BACKING THE TRUCK ON 3 SEPARATE OCCASIONS SINCE RECALL ADDRESSED, BRAKES BECOME MUCH LESS RESPONSIVE WITH CLICKING SOUND. BRAKES BECOME HARD TO PRESS AND DO NOT STOP VEHICLE COMPLETE. THIS ALSO HAPPENED WHILE TOWING A BOAT DOWN RAMP. THE VEHICLE HAS 28,000 MILES AND THE ISSUE DID NOT OCCUR PRIOR TO ABOUT A MONTH AGO. THE MOST RECENT TIME WAS TONIGHT WHILE BACKING ON LEVEL GROUND INTO GARAGE. I HAVE NOT HAD AN ACCIDENT AS A RESULT OF THIS, BUT THE RECALL WAS NOT ADEQUATELY PERFORMED OR DID NOT ADDRESS THE ISSUE.

AT LOW SPEED OR MOST OF THE TIME BACKING UP BRAKES DO NOT WORK WELL AT ALL. NEED TO PUSH VERY HARD.

I WAS DRIVING ON I-4 TOWARDS ORLANDO AT 70MPH FOLLOWING A SAFE DISTANCE TRAFFIC WAS COMING TO STOP AND I WENT TO BRAKE AND THE BRAKES WOULDNT WORK PROPERLY AND CAUSE ME TO PULL VEHCILE TO ONE SIDE CAUSING ME TO CRASH SAW LIFE FLASH BEFORE EYES . THANKFUL TO BE ALIVE , COMES TO FIND OUT THERE WAS A RECALL ON IT

I OWN TWO GMC SIERRA TRUCKS YEARS 2014 AND 2017 BOTH TRUCKS HAVE SEVERE LOCK UP ISSUES. I HAVE GONE TO THE DEALERSHIP NUMEROUS TIMES AND THEY RESET THE COMPUTER BUT THE BRAKES STILL LOCK UP. THIS IS AN EXTREME SAFETY HAZARD, AND MY WIFE AND I ARE EXTREMELY SCARED THAT WE WILL BE IN A FATAL ACCIDENT. THERE HAS BEEN SEVERAL TIMES WHERE WE HAVE ALMOST HIT A CAR OR PERSON WALKING. I AM REALLY CONCERNED THAT THESE VEHICLES WILL CAUSE AN ACCIDENT. MY CHILDREN ARE ALWAYS IN MY TRUCKS END IT IS EXTREMELY SCARY WHEN EVERY TIME I HIT THE BRAKES I AM NOT SURE IF IT WILL STOP OR NOT. THIS IS AN IMPERATIVE MATTER. *TR

MY BRAKES ARE NOT WORKING TO ITS FULL POTENTIAL. I BELIEVE MY VACUUM PUMP IS GOING BACK ON MY TRUCK. I NOTICED LAST WEEK THAT I WAS DRIVING OUT OF A PARKING LOT AND COMING TO A STOP SIGN AND I PRESSED MY BRAKES AND IT WAS NOT WORKING PROPERLY. I HAD TO RELEASE THE BRAKE AND SLAM ON THE BRAKES AGAIN ALMOST CAUSING A ACCIDENT WITH INCOMING TRAFFIC. I CALLED ALL MY LOCAL DEALERSHIPS AND STATED THAT THERE WAS NO RECALL ON THIS JUST YET FOR MY TRUCK, BUT THERE IS A RECALL ON THE VACUUM PUMP. THEY STATED THEY ALREADY DID THE SOFTWARE UPDATE TO MY TRUCK BACK IN SEPTEMBER 2019. MY TRUCK WAS GOING MAYBE 10 MPH TO A STOP SIGN AND I APPLIED MY BRAKES ONCE AND WAS NOT COMPLETELY STOPPING, SO I TOOK MY FOOT OFF THE BRAKE PEDAL, AND IT GOT WORSE AND I HAD THE BRAKES PRESSED ALL THE WAY DOWN TO THE FLOOR. THIS IS NOT SAFE! THIS IS MY DAILY DRIVER AND I DROP MY KIDS OFF TO SCHOOL EVERY DAY AND ITS NOT A GOOD FEELING KNOWING MY BRAKES CAN GO OUT AT ANY TIME!
