2023 GMC Sierra 1500 transmission problems

POWER TRAIN

My 2023 GMC Sierra 1500 SLT 4WD currently at 67659 miles was taken in to the dealer because of excessive jerk when accelerating or trying to reverse, diagnostic scan failed for check engine and ABS trouble codes. The scan return code PO747 indicating transmission pressure control solenoid “A” was stuck on for a predetermined period of time. The recommended repair is replacement of automatic transmission, solenoid control valve body. I’m aware that GM has issued a TSB 25–NA-255 and special coverage N24245441–02 addressing this exact failure on the GM 10 speed and that GM previously issued a related recall N242454440 addressing this exact failure on the GM 10 speed transmissions, and that GM previously issued a related recall for this citing rear wheel lock up risk associated with transmission valve condition. My vehicle scan showed an ABS failure at the same time as a transmission. code, consistent with the safety risk. GM has already acknowledged and its own recall documentation however I was told to contact NHTSA to document the safety risk and request investigation of the scope of this defect across affected models years and vehicles as mine seems to have fallen short. I previously owned a 2021GMC vehicle same model that experience the identical transmission valve body failure that vehicle could not be repaired in a reasonable time and I ultimately experience financial loss and had to replace a vehicle now I’m experiencing the same defect on the vehicle purchased (this one) with significantly fewer miles than would be expected for a major transmission failure, indicating that this may be a reoccurring manufacturing design defect rather than an isolated incident. Thank you for your time and I hope this issue can be resolved as I do love the truck otherwise however safety first. Thank you

While towing my trailer the vehicle intermittently slams gears and will hesitate the back tires momentarily to the point of screeching. This has led to close calls being nearly rear ended and having to pull over. This started out as a hard slam while trailering on the highway and has progressively gotten worse. Had into dealership twice to multiple times to try and figure out the issue but it’s not throwing any codes and they can’t get it to duplicate the issues. Nothing can be replaced due to no codes even though they think the valve body is going bad. Leaving the vehicle as a ticking time bomb for failure which could result potentially in a catastrophic incident. Only had the vehicle for one year now has 37k miles on it and have had the ecm, full wiring harness, and multiple sensors replaced already for a different problem early this year that had the truck in the shop for a month.

Engine light came on while driving and a message on dashboard said Service Transmission Now.Unable To Shift Soon. Took to dealer and they said it was the park position switch 1circuit high. Had to order part but not knowing how long to get it. Truck only has 12468 miles. Luckily I got it to the dealer ASAP. IF I were on the highway or a remote road, I feel that a serious accident would have happened. Having an electronic controlled console shifter not being able to get the truck to shift gears to slow down or stop is a real safety issue. Extended warranty does not cover anything like this. Please look into this. Thank you

I was driving my family on the highway and my truck completely shut down. The screen flashed a warning and it slowly started decelerating. Thankfully I was able to make it to the shoulder of the road safely. Engine failure was a known safety issue with my model of truck, but I completed the L87 Engine Loss of Propulsion safety recall testing on 9/18/2025 and was assured my engine passed the testing and was not at risk for engine failure.

While traveling at highway speed during rush hour commute, the vehicle lost engine power and stalled. While coasting, I tried to restart the engine several times without success. Before coming to a stop, I attempted to get to the shoulder safely. Unfortunately, a portion of the vehicle was left partially in the lane and on the shoulder. Once I was completely stopped, I tried to put the electronic shift control into neutral so I could push the vehicle safely to the shoulder. The shifter would not allow me to shift into neutral and other override methods researched failed to work. I continued to try and restart the vehicle without success. I was in an unsafe position during rush hour commute for about 50 minutes until roadside assistance arrived and loaded and towed the vehicle. There was no warning of the issue prior to the incident. A code (P129F-Fuel Pump Driver Control Module Speed Signal Incorrect) was produced after the stall occurred via my GMC app. My vehicle was towed to my local dealership for service, but have not received the vehicle back at the time of reporting.

[XXX] [XXX] Phone: [XXX] Vehicle Information: Year: 2023 Make: GMC Model: Sierra Denali Ultimate Engine: 6.2L V8 VIN: [XXX]: Mileage: Approximately 52,000 miles BACKGROUND: I previously had the engine serviced under a GM recall campaign related to known 6.2L V8 engine concerns. Despite that repair, the vehicle has since experienced two separate highway-speed loss-of-propulsion events. COMPLAINT The vehicle suddenly lost power while being driven at highway speed. No warning lights, check-engine lights, reduced-engine-power messages, or transmission warnings appeared. In both incidents, I was forced to coast to the shoulder of the roadway. The vehicle would not resume normal operation until it was stopped and restarted. This condition has now occurred twice. SAFETY CONCERN The sudden loss of propulsion during highway operation creates an immediate safety hazard and increases the risk of collision due to the inability to maintain speed with surrounding traffic. REQUESTED NHTSA ACTION 1. Record this complaint as a repeat loss-of-propulsion event. 2. Evaluate whether similar complaints exist involving 2023 GMC Sierra Denali Ultimate vehicles equipped with the 6.2L V8. 3. Consider this complaint in any current or future investigations involving loss of propulsion, stalling, engine failure, or powertrain concerns. 4. Review whether vehicles previously repaired under GM recall campaigns continue to experience similar failures. [XXX]: Update – Vehicle Disabled and Awaiting Engine Replacement Since filing my initial concerns regarding repeated loss-of-propulsion events, the condition of my vehicle has significantly worsened. During the dealership's inspection and test drive, the engine reportedly failed and locked up. The vehicle could not be restarted and required further diagnostics. On June 20, 2026, I received a text message from the dealership that the required engine parts remain on backorder INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

the vehicle is actively presenting severe mechanical symptoms that make it entirely unsafe to operate on public roads. Specifically, it exhibits a violent shuddering and vibration through the cabin when coasting or cruising at highway speeds. Furthermore, it undergoes aggressive jerking, harsh engagement, and dangerous hesitation the moment I press the gas pedal to accelerate or merge.

Model: Sierra Denali Ultimate Engine: 6.2L V8 VIN: [XXX] Mileage at Most Recent Incident: Approximately 52,000 miles Safety Complaint Summary I am submitting this complaint to report a recurring loss-of-propulsion and engine power event involving my 2023 GMC Sierra Denali Ultimate equipped with the 6.2L V8 engine. This vehicle has experienced two separate incidents in which it suddenly lost power while being operated at highway speeds. During both events, the vehicle unexpectedly lost propulsion without warning and without any apparent driver input or mechanical indication beforehand. No warning lights, check-engine lights, reduced-engine-power messages, service transmission messages, or other warning indicators were displayed prior to the failure. The vehicle simply lost power while traveling in traffic. During both occurrences, I was forced to safely maneuver the vehicle to the shoulder of the roadway while rapidly losing speed among surrounding traffic. Once stopped, the vehicle would not resume normal operation until it was restarted. After restarting, the vehicle appeared to operate normally; however, the fact that this condition has now occurred twice raises significant concerns regarding the reliability and safety of the vehicle. Safety Risk This condition presents a significant and immediate safety risk because sudden loss of propulsion during highway operation can leave the driver unable to maintain speed, safely merge, maneuver, or avoid surrounding traffic. The unexpected reduction in speed creates the potential for rear-end collisions, loss of vehicle control, or other traffic accidents, particularly when operating on high-speed roadways. Because the vehicle provided no warning before losing power, there is little opportunity for a driver to take preventive action.

I was driving down the road at 55 mph on 4/12/2026 and had let off the gas for a 45 mph zone when I experienced a violent downshift of the transmission that squealed the tires momentarily and felt like someone had hit me from behind. It startled me and caused me to lower my speed down to 20 mph. I continued driving to my destination and when I let off of the gas doing 45 mph for a slight curve I had another violent downshift that felt again like someone hit me from behind. I contacted a GMC dealer on 4/13.2026 to see if there was a recall on the transmission that I wasn't seeing online and was told no. I described what I experienced to their service department and was told to flush out the transmission fluid and replace the filter. I did experience another bad downshift at a slower speed (about 25 mph) on 4/13/2026. There wasn't any warnings or lights that came on when these three incidents occurred. When looking online I did see there was a similar recall for 2020-2022 GMC Sierra's where customers were experiencing similar violent transmission downshifts and am wondering if this issue is affecting more than just those three model years.

On March 13, 2026 I purchased a 2023 GMC Sierra AT4 Pickup with 3.0 Diesel Engine. While driving on a state highway in a 35 mph zone I started to accelerate as the speed zone changed. The truck suddenly had the rear wheel lock up for a brief time about quarter to half second then the truck proceeded on. This happened as the transmission was downshifting. Then on or about March 24, 2026 I was using the same truck and towing a 4,000 pound enclosed trailer. This trailer was hooked up within all recommended hookup requirements. In a 225 mile trip I experienced the same rear wheel lock up happen 4 random times during the trip. Once this happened at 65 miles and hour had there been snow or ice on the highway the truck may have crashed. This lock up happened while using the truck in tow haul mode. Two times it happened while the truck was being towed with cruise control active and two times it happened while not using cruise control. Truck was brought to Authorized GM Dealer and inspected and truck had no stored codes from transmission related issues. Dealer blamed this for using cruise while towing. I informed dealer this happened while not using cruise as well. Was told to turn off adaptive cruise when towing. I was unable to find anything in the GMC Manual regarding not using cruise while towing. This appears to be an issue with the valve body in the transmission and customer explained this to the dealer but they denied this claim. When these quick moment lockups happen no codes or engine lights show everything on dash appears normal. Customer is bringing truck to another GM Dealer to be tested and examined.

Incident Summary: On 2/2/2026, my vehicle was serviced under Safety Recall 25V-274 at an authorized GMC dealership. The service technician performed the mandated diagnostic protocol (including the PicoScope test) and informed me that the engine had "passed" inspection. No internal components were replaced; the remedy was limited to an oil change to a higher-viscosity oil (0W-40) and a new oil filler cap. The Failure: Approximately 48 hours after this "successful" recall remedy, the vehicle suffered a catastrophic engine failure while in operation. The engine failed entirely. The vehicle lost all propulsion while in motion, creating an immediate safety hazard for myself and other motorists. Diagnostic and Risk: The failure has been confirmed by a GMC dealer, who subsequently performed a full engine and radiator replacement. In the 48-hour prior to failure, there were no warning lamps or symptoms; the vehicle had just been cleared by the manufacturer's own diagnostic tools as safe and free of defects. Systemic Concern: This incident demonstrates that the current diagnostic protocol for Recall 25V-274 is insufficient to identify terminal manufacturing defects in the connecting rods and crankshaft of the L87 6.2L V8 engine. The "remedy" of higher-viscosity oil failed to prevent the exact catastrophic loss of propulsion the recall was intended to address. The replaced engine is available for inspection upon request by the NHTSA Office of Defects Investigation.

I am writing to formally file a safety complaint regarding the ongoing recall of the GMC/Chevrolet 6.2-liter V8 engine and what I believe to be an inadequate and insufficient remedy being provided to vehicle owners. I purchased a brand-new 2023 GMC Sierra AT4 equipped with the 6.2-liter engine. I drive approximately 6,000 miles per year and maintain the vehicle carefully. After receiving the recall notice, I promptly took my truck to an authorized GMC dealership for inspection and repair. The only action taken was an oil change to a heavier-weight oil. I was told that everything was “fine” and that no further action was required. I find this remedy unacceptable given the severity and nature of the reported failures associated with this engine platform. Simply changing to a heavier oil does not address the underlying mechanical risks and does not provide owners with meaningful assurance that catastrophic engine failure will not occur without warning. This issue is particularly serious for me because I rely on my vehicle for my livelihood. I am an account sales executive and use this truck extensively for work travel and customer meetings. If my vehicle were to fail unexpectedly, it could cause me to miss critical business meetings, resulting in immediate financial loss and potentially long-term damage to customer relationships and sales performance. The current remedy provides no confidence that such a scenario will not occur. In addition, this recall has materially harmed the resale and trade-in value of my vehicle. Dealerships are now significantly lowballing trade-in offers because the 6.2-liter engine recall is widely known and prospective buyers are reluctant to purchase these vehicles. Buyers are also aware that any future owner will not receive the benefit of the original powertrain warranty coverage in the same way, further depressing resale value. As a result, I am effectively trapped in a nearly new vehicle that has become difficult to sell or trade due

This malfunction is ongoing and the dealership cannot fix the problem. The first time it happened in September 2025. I was driving down the road and the gauges started to go crazy. The screen on the dash said reduced acceleration. Then it said Service ESC. Then it said Service Traction Control. It would not let me go over 40 mph. I took it to the dealership and they told me I needed a valve body replacement. They installed the valve body and that did not fix the problem. It happened again and said reduced acceleration took over forcing me to pull over on the side of the road. The GMC dealership said to bring it in again but they could not reproduce the malfunction after driving for a week. It happens randomly. The third time this happened I was traveling up interstate 24 at about 70 mph. There were semi trucks around me when the malfunction happened and my acceleration and speed was reduced throwing the RPMs as high as they would go, and I was almost hit by a semi trying to move out of the way and onto the shoulder of the interstate I tried to accelerate to get out of the way of the semi truck but could not. I had to swerve over almost losing control of my truck. I informed the dealership that this had happened again and they asked me to bring it in. I did. They told me they were going to clean corrosion off of ground wires, and that should fix the problem. It did not. This keeps happening and I feel that the vehicle is not safe to drive. I do not know when it will happen again. I travel for a living and I feel the vehicle is unsafe to operate.
