Defect Description:

POWER TRAIN

Potential Consequences:

Code P0777 – "Pressure Control Solenoid 'B' Stuck On" – Reduced Propulsion / Reduced Engine Power Initiated While merging onto the interstate, this code triggered a reduction in engine power, limiting my speed to 35 mph on a highway with a posted limit between 40-70 mph. Due to the limited power, I was forced to drive on the shoulder to reach the next exit and pull into a service station. I verified the code using an OBD-II reader at AutoZone. Subsequently, I had the truck towed approximately 1 hour and 30 minutes back home. The vehicle has been at a GM dealership since June 24th, where the faulty valve body has been confirmed. However, there is currently no estimated arrival date for the replacement part, which was ordered on the same date. To my knowledge, the part has only been diagnosed electronically and has not yet been visually inspected. The dealer plans to remove the valve body and transmission pan once the replacement part arrives. Notably, there were no prior warnings, messages, or symptoms before this issue occurred; this code and power reduction were the first indications of a problem.

STRUCTURE:BODY

Potential Consequences:

My truck is experiencing an issue that is already a recall for similar trucks, but my VIN is not included in the recall. My tailgate opens on its own. This sometimes happens when I am driving down the road. This is a safety risk because if I am hauling something in the back, and the tailgate drops down, there is a chance the load could fall out of the truck and harm another vehicle or person that is behind my truck. I brought the truck to the dealer and they said they could not find any evidence of this issue, even though they stated that it is a known issues with these trucks. There were no waring lamps or messages. The only symptoms are that the battery can die if the truck is not used for a day or more and that the tailgate opens on its own whether the truck is parked or driving.

Corrective Action:

Replaced the exhaust tail pipe tip past the DPF and warning light came on after miles of driving. Vehicle was locked up and only able to drive 55 Mph and there was a countdown to it dropping even lower. Dangerous to limit speed. This shouldn’t happen anyway with just changing out exhaust tailpipe. Very costly unnecessary repair

STEERING

Potential Consequences:

My truck wonders down the highway. It has been to the dealership well over 4 times. They have aligned the truck multiple times, changed the steering gear box, changed the power steering pump, changed tires and nothing fixes it. It takes constant adjusting of the steering to stay in my lane on any road. Quite pitiful for a $90,000 truck. It is currently at the dealership for the THIRD time in the past 7 days because they can’t get the truck to stop leaking fluids since changing the power steering pump. Excessive play in the steering and has been like that since day one that I left the lot. My wife can’t even drive the truck because she feels unsafe with how much play is in the steering. The dealership won’t do anything about it and is offering $20,000 less than I gave for the truck now that I can’t tolerate it anymore. But I refuse to lose that much money with only 13,000 miles on it. I just want a safe and reliable truck for my business and my family. Unfortunately that is not what GM has provided me with.

UNKNOWN OR OTHER

Potential Consequences:

The AC/Heat blower (fan) stopped working. The vehicle was new purchased new May 2023. August 2024 the blower motor stopped working. Took the vehicle to Jerry's GMC Weatherford, TX (where it was purchased) and they check the blower motor and replaced it. No charge for the service. Reason given for blower motor problem was, "motor shorted out, burnt the wiring and the connector". Now, February, 2025, the blower motor stopped working once again. Took it back to Jerry's GMC, Weatherfore, TX. The blower motor had shorted out once again, burnt the wires and connector. Reason given for the reaccurring problem, " the blower motors they are getting have a bearing problem, causing the motor to go to ground, overheat the wiring and burns the connector". They replaced the blower motor once again and no charge. The reason for this notice is, With these motors shorting out because of internal problems, the wiring melting and connector melting, there is the possibility of a fire hazard. We feel that there needs to an investigation into this problem before something happens. Thanks

SERVICE BRAKES

Potential Consequences:

024 GMC Sierra 2500 Denali Ultimate, which has suffered: •Five catastrophic engine failures at highway speeds. •Total brake failure, leaving the truck unable to stop. •Severe electrical malfunctions, including flickering headlights at night. •Retaliatory actions from General Motors after I refused to waive my legal rights. I have documented proof, including GM’s own service records, emails, and a 7-minute recorded statement from GM’s highest-level technician, confirming that GM installed the wrong computer module (1500 series instead of the required 2500 series) in my truck. Additionally, I have evidence that GM executives instructed technicians to conduct diagnostics, take apart the engine, and reassemble it—but NOT repair the defect—after I refused to sign an affidavit waiving my rights. Due to these failures, I suffered a dislocated shoulder in one of the incidents, and my [XXX] daughter remains traumatized to this day. Given the immediate danger this defect poses to other GMC Sierra 2500 owners, I respectfully request that NHTSA open an investigation and consider issuing a recall before a tragedy occurs. 1. Engine Failures Since 3,000 Miles – GM’s Own Work Orders Confirm Issue Since purchasing my 2024 GMC Sierra 2500 Denali Ultimate, I have experienced five catastrophic engine failures, all occurring while traveling at highway speeds (70 mph): •The truck suddenly lost power, dropping from 70 mph to 5-10 mph within seconds. •This created an immediate risk of being rear-ended or losing control on the highway. •GM’s own service records confirm that my engine issues began at just 3,000 miles. •GM dealerships misdiagnosed the issue FOUR TIMES, returning my truck to me in an unsafe condition. •The real cause was only identified after the FIFTH failure, when a GM-certified head technician finally determined that GM had installed the wrong computer module (1500 series instead of 2500 series). This means that for months, GM knew my vehicle w INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA
