2017 GMC Acadia Brakes Problems

Subject of the problem: Service brakes/Hydraulic brakes Problem of the vehicle: While driving, the brake pedal sometimes suddenly goes all the way down without resistance, and the vehicle does not slow down as expected. In order to regain brake pedal twice. Frequency of the problem: This issue occurs intermittently, but it poses a serious risk because the vehicle may not stop when needed. I already had the brake booster kit and hose replaced at an authorized GMC dealership because I was told this was the cause. However, the exact same problem continues to happen after the repair. Safety concern: This appears to be a defect that affects braking performance and safety. The issue occurs intermittently while driving (e.g., at stop lights, low-speed braking, or during normal driving). It has happed multiple times since the repair. This problem could cause loss of braking power and result in a crash. It is extremely dangerous and has not been resolved by the manufacturer's recommended repair. I have called the GMC service center at 18004678782 and 18002221020 with this problem. They told me that they could do nothing about it and to deal with the dealership directly myself and they can not do anything. I have talked to the dealership but they just tell me there was another problem other than the initial problem they told me. The dealership did the first checkup and that problem was not fixed. Then went in again because the same problem was happening so they did another checkup and told me there was another problem not the initial problem they told me. The second checkup they did, the part and labor was $2,700. I went in with the same problem and have to pay that much. The problem was not solved with the initial diagnosis they gave and now have pay extra ($2,700 - second checkup price) to fix the problem they did not fix. Thank you.

Vehicle will apply breaks abruptly on its own whenever it thinks a vehicle is too close. Was in traffic and it kept slamming on the breaks as I would try and move forward. Will slam on the breaks whenever I attempt to just slow down during the course of driving. Was on the highway and anytime I pressed the breaks to slow down, automatic breaks would slam down breaks on its own. Drove vehicle right to dealership as the was a major safety issue for me especially with my baby in the car.

4-11-22 Wife and I drove from our house to the corner intersection. She put the breaks on and the pedal went to the floor and the car drifted into the intersection, across the street to a parkin lot and then we costed back to our house and had it towed to the local GMC Dealership. Asked for meeting with District Service Manager as I had paid to have vehicle fixed for my use. 5-3 and 4-22 Customer Service in MI agreed that it was a safety issue but out of warranty for brakes. Ok for brakes to go due to wear. 5-16-22 Gave District Service manager (PIE 0458 dated 3-22-18) which reads: "Brake pedal goes to floor with no external sign of a leak" GM KNEW. District Manager helped financially. If we had been in a car crash and died it would have been labeled we ran a stop sigh not that GM willingly put a possible death trap into the publics hands. Sending this because others may have been misdiagnosed concerning a crash. A PIE was issued but no Bulletin was issued

The ABS system indicated a problem. When I took it into the dealership, they told me the ABS was bad and needed to be replaced.

my car parking brakes will automatically come on while I am driving/ at a light or waiting to turn. I always push the brake pedal all the way down to decompress it and it is still hard to get going. This has put me in very dangerous situations causing my suv to lose power and often times if I am in the middle of a turn it locks up and make it hard to turn. I have took my car to the dealership twice and they have looked at my car and seems to not found a problem

THIS OCCURRED WHILE PULLING INTO A PARKING SPACE IN THE AFTERNOON ON MARCH 12, 2021 AT APPROXIMATELY 2:30PM.... UPON DEPRESSING THE BRAKE PEDAL THE PEDAL WENT ALL THE WAY DOWN AND THE CAR LURCHED CRASHING INTO A LIGHT POLE. FORTUNATELY THE LIGHT POLE PREVENTED ME FROM HITTING ANOTHER CAR IN THE PARKING LOT. MY AIRBAG DEPLOYED SLAMMING INTO MY CHEST AND I MANAGED TO PUT THE VEHICLE IN PARK. THERE WAS EXTENSIVE DAMAGE TO MY GMC ACADIA AND AAA AND MY INSURANCE WERE CALLED AND THE CAR WAS TOWED TO A COLLISION SHOP AS INSTRUCTED BY MY INSURANCE. I AM PRESENTLY AWAITING CALLS FROM MY INSURANCE AND THE ADJUSTER. THIS IS SATURDAY AND NOTHING HAS HAPPENED YET. I'M VERY DISAPPOINTED IN THE MANNER THAT THE VEHICLE PERFORMED AND I'M STILL HAVING CHEST PAINS WHERE THE AIRBAG HIT ME.

WITH VEHICLE PARKED I GET A MESSAGE OF SHIFT IN PARK AND VEHICLE DOESN'T FULLY TURN OFF. IT IS KNOWN AS AN ISSUE FOR GM VEHICLES - BULLETIN ISSUED.

ON SATURDAY, APRIL 11, 2020 THE EBCM, ELECTRONIC BRAKE CONTROL MODULE, SET OFF A PARKING BRAKE DASHBOARD LIGHT CAUTION. THE PARKING BRAKES NO LONGER ENGAGED. BELIEVING IT WAS A CERTIFIED WARRANTY ISSUE, I HAD IT REPAIRED, APRIL14, 2020, AT BURDICK CHEVY GMC BUICK. TURNS OUT IT IS CONSIDERED A 'WEARABLE PART' AND NOT COVERED. TWO DAYS LATER, APRIL 16, 2020, I DISCOVERED THE EBCM MODULE RECALL ON SIMILAR VEHICLES, ATTACHED AP ARTICLE. SINCE APRIL 16 UNTIL APRIL 23, I ATTEMPTED WORKING WITH GMC, AND THE DEALER, OBTAINING REIMBURSEMENT TO NO AVAIL. THEREFORE AFTER READING THE THE ARTICLE, THE DEALERSHIP, AND FOUR DIFFERENT GMC REPRESENTATIVES, I REQUEST AN INVESTIGATION WHETHER THIS EBCM MODULE ISSUE IS THE SAME AS THE ARTICLE. THANK YOU.

I WAS DRIVING MY 2017 GMC ACADIA ON THE HIGHWAY WITH MY SON IN THE VEHICLE WHEN IT SLAMMED ON THE BRAKES FOR NO REASON. WHEN I FIRST TOOK IT TO THE DEALERSHIP THEY DID NOT BELIEVE ME. THEY RESEARCHED THE ISSUE THEN INFORMED ME THAT GM WAS AWARE OF THE "PHANTOM BRAKING" PROBLEM AND ISSUED A BULLETIN TO THE DEALERS. THEY SAID THE WAY TO FIX IT WAS TO REBOOT THE COMPUTER. THEY WOULD NOT GIVE ME A COPY OF THE BULLETIN THAT SHOWED THE ISSUE OR THE FIX. GM KNEW THIS WAS HAPPENING IN THEIR VEHICLES AND THEY DID NOT TELL THE CAR OWNERS. IT IS A MIRACLE THAT IT DID NOT CAUSE AND ACCIDENT AND THAT NO ONE WAS HURT OR KILLED. I DO NOT FEEL SAFE DRIVING THIS CAR BUT THEY WILL NOT LET ME OUT OF MY LEASE EARLY.

WHEN DEPRESSING THE BRAKE PEDAL A SQUISHING NOISE WAS HEARD. THE SOUND WAS PRESENT WHILE MOVING AND WHILE STOPPED. MASTER CYLINDER WAS LEAKING BRAKE FLUID INTO BRAKE POWER BOOSTER

PARKING BRAKE FAILED TO ENGAGE--WAS TOLD BY DEALER THE MODULAR FOR THE PARKING BRAKE SYSTEM FAILED.VEHICLE WAS STATIONARY AT THE TIME

THE VEHICLES BRAKES BECAME DEFECTIVE AND STOPPED WORKING WHICH CAUSED AN ACCIDENT.
