ELECTRICAL SYSTEM, ENGINE, STEERING
The electric power steering failed while accelerating into a turn from a stop at an intersection. The wheel was jerked from my hands, and the engine stalled, all electrical failed momentarily. Within a couple of seconds everything returned to normal. This has happened several times since I purchased this vehicle. Also the electrical power steering drops out quite often at low speeds, such as in parking lots. No warnings have ever been given. In May of 2021 the dealer replaced the steering rack, the problem has continued intermittently to this date. I have researched for recalls on this problem and found that GMC issued a recall for years 2014-2017, and am amazed that they could just declare the problem fixed, and leave such a dangerous problem unresolved!

SERVICE BRAKES
On 9/20/23 my truck suffered a brake failure in which one of the front calipers ruptured and there was a complete loss of braking. The brakes were repaired the following day and an "ABS" light remained on after the brakes were repaired and the brake lines were bled. The vehicle codes were checked and a "C0110_04 Pump motor circuit open" fault was detected. It should be noted that even though the brake system was bled and and part were replaced, there were no brakes and the vehicle could not be driven. I had the vehicle towed to Rossi GMC in Washington, NJ and they diagnosed the problem as a bad Electronic Brake Control Module and Motor. Then I was advised by their service department that no parts were available because of the General Motors strike and there was no date as to when the parts would be available. I asked if I could try to locate the parts myself and they agreed as long as they were genuine GM parts. After calling hundreds of GM/Chevy dealers I was able to locate one (1) EBCM at All American Chevrolet/Cadillac in Muncie, IN. After speaking with their parts department, they advised me that they have the part and they won't sell it to me over the phone, only in person. I live over 9 hours away from the dealer and this was not feasible. My complaint is this, although the ABS system in my truck was not functioning properly should the regular brake system still be working? If so, why is mine not. This is a HUGE safety concern considering if the ABS system were to fail at highway speeds this could cause a bad crash.

ELECTRICAL SYSTEM: INTEGRATED TRAILER BRAKE CONTROL
When I connect my 2024 GMC Sierra 2500HD to my camping trailer that has a solar panel and solar charge controller, it causes the factory-installed brake controller inside the truck to malfunction. The trailer brakes connect and disconnect 4 times a minute sending alerts to my dashboard. This is dangerous. My trailer weighs up to 14,000 pounds and would have to rely solely on the truck brakes to slow to a stop. GM put out a Document ID: 6379278 / #23-NA-113 "Information on Trailer Brake Disabled or DTC Stored". However, there is no fix. The GMC dealer said they can't find the service bulletin?! Please make this issue a RECALL. I bought this truck to exclusively tow a trailer and now I can't.

ENGINE
With only 89K miles on my vehicle I’m having to replace 13K dollars worth of parts due to a known issue with the 5.3L V8 engine with the AFM DOD system that GM hasn’t fixed and refuses to help cover the cost cause I’m outside my warranty. I feel they need to extend the warranty miles and time frame due to the common occurrence of this issue

ENGINE
I am told by a GMC dealer that my engine mount is cracked/worn and needs replacing otherwise the engine can fall out. My mechanic tells me this is a common problem with GMC trucks; specifically the driver’s side engine mount. Perhaps a recall is necessary if this is a common issue. My vehicle is a 2018, so only 5 years old.

FUEL/PROPULSION SYSTEM
This is a 2016 GMC 3500 Denali truck with 70,000 miles on it. The Bosch fuel pump threw metal shavings into the fuel system. This is a known issue with GMC trucks with a Bosch CP4 fuel pump for 2011-2016. The engine suddenly quits running leaving the driver without power steering or power brakes. It happened to me when pulling a 14,000-pound 5th-wheel RV. Fortunately, I was on an interstate outside of Grand Junction CO and the road was flat. If I had been in the mountains going downhill and the engine quit I'd likely caused an accident perhaps fatal. GMC quoted me $16,000 to repair. Again, this is a known issue at GMC but they refuse to do anything about it. GMC Dealership in Grand Junction performed the analysis and advised me to drive it home to Phoenix. I got 60 miles when the engine quit. Cost me $1,600 to get the truck returned to my GMC Dealer in Phoenix and another $1,600 to get my trailer back home.

STEERING, ELECTRICAL SYSTEM
All power shuts off while driving. The transmission dis-engages, the power steering stops working and the infotainment system turns off. The power steering powers off even when sitting in a parking spot while everything else is on. I've owned this truck since 2019 and this has always been an issue, especially when taking a left through an intersection. I keep checking for recalls, but nothing shows up and I find that extremely hard to believe. I'm contacting you now because the issue has gotten worse, everyday worse.
