ELECTRICAL SYSTEM
Reverse lights stay on. Causing the battery to drain. The fuse box under the hood is prone to go bad. Even with no corrosion. GM knows this and has not fixed the issue. Its a common problem going back many years. The need to upgrade the fuse box under the hood & the wiring harnesses. My taillight harnesses were completely burned up. The truck could of caught fire. This should be a recall. Instead GM wants to take the money they are making off all the fuse boxes they are selling.

ENGINE, POWER TRAIN, SUSPENSION
In November 2023, my lifters collapsed and I had multiple bent pushrods on my vehicle due to the active fuel management system, leading me to become stalled in my vehicle on the middle of the road with no way of getting off the roadway safely. I have had multiple issues with this vehicle, and know many other who have as well. I had been compliant with all routine and preventative maintenance to this point, and I know that this will lead to injuries or fatalities due to these issues that GM is aware of, yet will not do anything to rectify the situation.

ENGINE, POWER TRAIN, UNKNOWN OR OTHER
To whom this may concern, This gmc truck with the 6.2 has had constant engine issues regarding the lifters failure causing the engine to destroy itself internally I’ve had to get it repaired every 3 Months on average there’s also a class action lawsuit that applies only to the 2025-2020 years however they are the exact same engine in the 2017. The transmission is not in sync with the motor having a late take off or sounds like the gears are grinding between shifting

ENGINE, FUEL/PROPULSION SYSTEM, SUSPENSION
Gear slipping since I’ve had the truck. Replaced parts of motor, new transmission installed and still gear slipping entering the second gear. A big jolt happens every time I accelerate and when I slow down about the 10 mph mark it jolts again. Spent well over $10,000 on major truck repairs. I just don’t understand how this truck has 0 recalls. My truck is similar to all of the v8 Sierras of that year and I strongly feel it should have been recalled due to the gears slipping and not enough power.

SERVICE BRAKES
I was test driving this 2017 Sierra 1500 SLT and experienced issues while braking. Issues with brakes as the vacuum level drops the brake assist decreases which meant I had to use excessive force to get the vehicle to stop. No warning light, nothing to tell me there is a low pressure brake. This could result in a fatality if a small animal or child walks/runs in front of the truck while truck is moving forward or backwards at low speeds. The dealer doesn’t acknowledge any recall on this vehicle because it isn’t noted as such with GM. I worry that all of the other recalls (4 others) may be an issue too, which include Frontal Airbags not deploying during an accident, faulty wheel sensor causes opposite wheel to engage and cause the vehicle to pull to one side, fuel leak, and child seat anchoring restraint instructions not included in the owners manual.

SERVICE BRAKES
My 2017 GMC Sierra Brakes started acting up a slow speed it would seem like there were no Brakes or Pedal would push very hard. I pulled into a parking space at the store and it was like I had no Brakes had to push pedal very hard and Thank god there wasn’t a car in front of me because I would have hit it. The truck has new front and back Brakes and Rotors put. The truck was throwing some codes and 3 out of the 4 codes pointed to faulty Vacume pump. I pull a camper and sometimes a side x side so this is very concerning and I hoping to get this expense covered by Recall like all the other Models with the same issues. I really don’t know why my truck isn’t being Recalled. This has been a good truck for me no complaints tell this.

STEERING
AT APPROXIMATELY 98,000 MILES, THE DASHBOARD ERROR MENU NOTICE TO SERVICE THE POWER STEERING SYSTEM. THIS VEHICLE HAS ELECTRONIC POWER STEERING. WHILE REVERSING AT LOW SPEED, THE POWER STEERING FAILED. I STOPPED THE TRUCK, TURNED OFF THE ENGINE, WAITED 15 SECONDS, AND RESTARTED THE TRUCK. THE ERROR NOTICE REAPPEARED AND STEERING POWER RETURNED AFTER ABOUT 15 SECONDS. DURING THAT 15 SECONDS THE STEERING WHEEL APPEARED TO OSCILLATE SLOWLY ABOUT AN INCH, THEN STOPPED. STEERING HAS BEEN NORMAL SINCE, THOUGH THE ERROR MESSAGE STILL APPEARS. I KNOW 2015 MODELS HAVE BEEN RECALLED FOR THIS SAME ERROR. I BELIEVE THE RECALL SHOULD BE EXPANDED.

ENGINE
My truck is currently experiencing the connecting rod and/or crankshaft engine components that may have manufacturing defects that has lead to engine damage and engine failure. My truck is currently being looked at a shop for this exact issue. GM recently recalled more than 597,000 vehicles due to engine failures, according to you, the National Highway Traffic Safety Administration. The recall however only lists vehicles within the years of 2021-2024. My vehicle has the same engine 6.2L V8 gas as the recall and I don't find it a coincidence that I have the same EXACT engine experiencing the same EXACT issue! I attempted to speak to GM but they just kept saying my vehicle is not listed on the recall and refuse to investigate this. I included my conversation with them.

POWER TRAIN
I had to replace my transmission at 71902 miles. I complained to Flow GMC dealership over seven times about the Vibration , jerking, shaking and shuddering. Most of the time when I carried they said they can not duplicate the problem. On Feb. 05, 2025 I was driving and stopped at a stop light when I pulled off the vehicle started vibrating, shaking and had a hard jerk. I thought someone had ran in the back of me but that was not the case . I had it pulled in to Flow GMC they checked it out and said the transmission need to be replaced. I had it replaced at the dealership. I had to pay $7782 to get a new transmission. I read were they being are all on some GMC models. I want to know why the 2017 GMC has not been recalled.
