SERVICE BRAKES
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.

SERVICE BRAKES, ELECTRICAL SYSTEM
I’m having a trail break system warning every few minutes. It is constant and beeps consistently. To the point where I almost cannot drive it. It won’t go away after a little while and is constantly turning on and off. This just recently occurred and hasn’t stopped since. Likewise there was no other indication of this happening till about two days ago. It’s very distracting and persistent to the point where I feel like I can’t even drive with it on.

ELECTRICAL SYSTEM, SERVICE BRAKES, ENGINE
While driving on a two lane road I proceeded to pass a slow moving vehicle, after accelerating from 45 MPH to 60 MPH my Check Engine light, Service Electronic Stability Control (ESC) and Service Electronic Brake System lights illuminated on my display. My RPMs increased before shifting gears and I noticed a significant loss in power. Thankfully there was not an accident when the incident occurred; however, if an oncoming vehicle or bad weather it could have been a different outcome. I took my vehicle to a GMC dealer to diagnose the issue where I found out my lifters for my valves are bad and my fourth cylinder is inoperable along with a bad CAM. A new vehicle at 65K miles on it should not be having mechanical issues that can pose a danger while driving, putting others and my safety at risk. GM needs to reevaluate the products and materials their using to build engines to ensure there are no flaws starting with the valve lifters.

STEERING
Becomes hard to turn steering wheel at slow speeds, more often while in reverse. On one occasion, a Stabilitrak message popped up as a warning and then the engine died. Does not happen every time but has happened enough to take it to the dealership. They concluded that it could not be duplicated so they could not properly diagnose the issue. They had the truck for 3 days of testing. The engine failure is seriously concerning to me due to having my children with me most of the time.

SERVICE BRAKES
Brake pads have excessive squealing. Squealing implies incorrect pressure to rotor to stop the vehicle, which highly concerns me as an operator. According to the dealer where I reported the issue, there is a technical bulletin that approves replacement of the brake pads for free if reported in first 7500 miles. My truck exceeded that mileage when I noticed the squealing. If this was a recall for the defective brakes, the dealer would cover the costs to repair, but not for a technical bulletin according to the service department, and confirmed by GMC. I now have to pay $1500 to replace brakes on a new truck with 15000 miles on it, or risk my safety. I believe this should be a recall and appreciate any assistance in this matter.

The contact's father owns a 2020 GMC Sierra Denali 3500. The contact stated that while his father was driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer and diagnosed with a cylinder #1 misfire. The vehicle was repaired; however, the failure recurred. The vehicle was then taken to Wackerli Auto Center (1363 N Holmes Ave, Idaho Falls, ID 83401) on numerous occasions and diagnosed with a faulty sensor. The dealer replaced the sensor; however, the failure recurred. The vehicle was not repaired and remained at the dealer. The manufacturer was made aware of the failure.

VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM, SERVICE BRAKES
The truck displayed warning lights for ABS, traction control, trailer brakes, and front park assist. Additionally speed control (cruise) did not function. This presented a safety issue. I took to dealer asap. They repaired by replacing left rear wheel speed sensor. Cost about $216. Appears to work correctly at this time.

SUSPENSION
At 8,000 miles I started hearing a clunking noise in my truck when I hit a small bump or back up out of drive way. Brought in and GMC stated it was normal and no issues at walser buick gmc of Roseville. Brought I back again because it was getting worse and could hear it every time I slowed down and accelerated. Then stated they need to order spacer bushings at walser of Bloomington. Then went back for 3rd time and installed them at Bloomington.After 600miles noise was back and is getting worse again. I called Walser of Bloomington again and said I need to drive it for 1000 miles to break in spacers. So now we have 11,000 miles on truck with same noise again and its going back again because needs to get fixed. GMC is just asking for something to happen. Also when this first happened at 8,482miles I was on 35w and the rear end started wobbling and gave me a small death wobble but I slowed down to control it. That’s when I brought it in and it could of hurt or killed somone.

POWER TRAIN
I'm having issues with my transmission/torque converter on my 2017 GMC Sierra SLT 6.2L which cause a heavy shutter and/or shake while driving. I have scheduled a follow up appointment for 11/22/21 after my vehicle was just in on 11/15/21. I currently have less than 57,000 miles on this vehicle. These issues create abnormal vibrations and shuttering under normal driving conditions which can adversely affect control of the vehicle. Furthermore, these issues affect acceleration and deceleration.

ELECTRICAL SYSTEM
Infotainment system AND center instrument cluster went completely black - six times over the course of one month. I took the truck to Alan Webb Chevrolet in Vancouver Washington. Their service technician was aware of infotainment system “Black Screen of Death - BSD” problems due to previous repair work on several different GM models. However, on the way to their Service Department to get this fixed, I rolled down the driver’s side window about 6 inches to get some fresh air and rolled it back up. Out of nowhere the Infotainment system AND the center instrument cluster came back to life. No rhyme, no reason and both stayed on (illuminated). Their Service Technician could NOT recreate the BSD. They had my truck for more than one week AND said they were working with GM engineers to resolve this issue. GM case number SR 9-7065134382. I’m driving and towing my 5th wheel blind without a remedy for this electrical issue.

SERVICE BRAKES, ELECTRICAL SYSTEM
Trailer Brake system warning continues to pop up on my dash along with the chimes. Not sure if this will affect my braking or not, but I pull a 32' camper and am continually concerned about this warning. It happens randomly not just when towing a camper. It has been in to a GMC dealer and they say nothing can be done about it due to no recalls.

SERVICE BRAKES
Brake pedal has to be pushed almost all the way to the floor to stop, this recently changed from barely having to apply any pressure to the pedal. Took it to Quebadeaux gmc on 11-10-2021 and they inspected the brakes, said everything was good and that’s normal for the brakes to be that soft. That’s not normal or it would’ve always been like that.
