The transmission lost the ability to move the vehicle. The valve body for the transmission became inoperable at 7,600 miles. This is a safety issue because it can leave people stranded in cold/inclement weather. This happened without warning and the dealer replaced a spacer and check balls for the valve.

Truck suddenly refused to shift gears/stopped moving forward in HEAVY TRAFFIC, placing me and my family--and others on the roadway--in danger. Dealership inspected the vehicle on three separate occasions for the same (recurring) issue, replacing the control valve body on one visit and the entire transmission on the third. No advance warning that the issue was about to occur on any of the three instances, but check engine light came on afterward along with a message reading "reduced acceleration/drive with care".

On [XXX], I was going to Atlanta, the truck started hesitating harshly while I was passing another driver on a two lane road. The truck wouldn’t accelerate and the paddle seemed to be stuck, I had to pull off the road to avoid a head on collision. On the 30th of May, I took the truck to Allen Turner in Pensacola, Florida where I purchased it and reported the issue, the service department was closed and they sent me next door to a Chevrolet Dealership, which was also closed. On today [XXX], I took the truck out for a test drive, and I had the same incident happen, but this time I pulled into a gas station and shutdown the truck. Once I turned the truck back on, the check engine light came on. I didn’t think I would make it back home, because the truck didn’t accelerate correctly, and when I pressed the gas pedal it didn’t accelerate and was making different noises. The pedal seemed to be stuck, with no acceleration. I recorded a little bit with my phone while trying to drive, but it’s not the best.

The primary failure is in the electronic transmission control system and engine wiring harness assembly, specifically throwing diagnostic trouble codes P0700 (Transmission Control System Malfunction) and P0717 (Input Speed Sensor Circuit No Signal). The authorized dealership identified a critical issue with the engine harness chafing, but their subsequent repair attempts have failed to resolve the recurring powertrain failure. The complete vehicle and all affected components are currently parked and fully available for immediate physical inspection at my residence upon request. While operating the vehicle at highway speeds, the powertrain abruptly loses throttle response and forces itself into a severe, uncommanded "Reduced Power / Limp Mode." This creates a severe safety hazard by instantly dropping vehicle velocity on active interstates and high-speed roadways, leaving the vehicle unable to accelerate out of harms way or merge safely, placing myself, my passengers, and surrounding motorists at immediate risk of a high-speed rear-end collision.The malfunction has been repeatedly confirmed and documented by authorized GM service agent Rountree Moore Chevrolet (Lake City, FL) across three separate service visits. The dealer confirmed the active trouble codes and attempted various repairs (including Transmission Control Module reprogramming on 04/24/2026, engine harness chafing repairs on 05/19/2026, and auxiliary fluid/battery adjustments on 05/21/2026). The persistence of the failure confirms the dealer has been unable to successfully remedy the defect. To date, the vehicle has only been inspected and worked on by the authorized dealership's factory-trained technicians. It has not yet been involved in a collision requiring police or insurance representative inspections, nor has a corporate field engineer from General Motors inspected it outside of the local dealership level.The failures are consistently preceded by an illumination of the dashboard Check Engine

While driving, the truck suddenly Boggs down and gets sluggish. A message appeared once that said reduced acceleration drive with care. It is dangerous because it loses power and stalls in front of other vehicles. I took it to the dealership on Friday the 17th and they said it was the crank position sensor. They ordered the part and I took it back on Monday the 20th and they replaced the sensor. Today, while driving down the highway it did the same thing again. I will be taking it back to the dealership tomorrow. The truck has 26,000 miles on it.

What is happening with my vehicle is a major safety concern in my opinion for myself and for my family. I purchased the vehicle on February 18,2026 from Ryan Ford in sealy,TX with approx 32,800 miles. The first incident was on March 16 with 33,718 miles, my daughter and I went to leave the Lowe’s parking lot and my vehicle would not go in reverse. It however would go in drive, so after being pushed back out of the parking spot we left for our home.(this part of not going in reverse I do have on video) Once on the feeder road and up to approx 45mph my vehicle went completely out of gear and had to coast to a stop on the side the road. Turned vehicle off and on and it went back in gear, after making it home I made and appointment with the dealership and dropped it off that day. I was informed no codes came up and the dealership could not get the issue to duplicate so I received my vehicle back. The second incident was on March 21 trying to leave the convenient store, I put my vehicle in reverse and pressed on the gas to go backward and nothing happened. Then I pressed on the gas again and it threw my vehicle in reverse and jolted my truck back several feet before I could press on the brake. Luckily no one or no object was behind me. The third incident was on April 3rd trying to leave Walmart. My truck would not go in reverse again. I pressed the gas pedal several times and out of nowhere again it threw itself in reverse and jolted my truck back again. (I also have this on video as well).

Summary of Incident: On March 28, 2026, while traveling at 70 MPH on the Florida Turnpike, the vehicle suffered an instantaneous loss of motive power. The engine died abruptly with no warning. Upon reaching the shoulder, the electronic transmission locked, refusing to shift into Neutral or Park. The engine cranks but will not start. 1. Component Failure & Availability: The exact component is currently unknown, but the failure involves the Powertrain, Fuel System, and Electronic Transmission Control. The vehicle is currently at an authorized dealership and is available for inspection by the manufacturer or NHTSA upon request. 2. Safety Risk: The sudden loss of power at highway speeds created an immediate risk of a rear-end collision. Because the electronic transmission locked and would not allow the vehicle to be shifted into Neutral, it became a fixed object on a high-speed shoulder. It could not be pushed to a safer location, increasing the risk of a secondary accident. 3. Problem Reproduction: The vehicle was towed directly to an authorized Chevrolet dealership. As of this filing, the dealership is in possession of the vehicle, but the failure has not yet been reproduced or confirmed by a technician as they are awaiting formal diagnostic commencement. 4. Inspections: The vehicle was inspected by a roadside towing professional for transport. It is currently at the manufacturer’s authorized service center awaiting a formal diagnostic inspection. No police or insurance inspections have occurred. 5. Warning Symptoms: There were no warning lamps, "Check Engine" lights, or messages prior to the failure. No symptoms like rough idling or unusual noises occurred. The vehicle performed normally until the moment of total power loss.

I was driving down the highway and the vehicle suddenly shutoff without any warning. I coasted down an off-ramp and came to a stop in the middle of a round about. The vehicle would not re-fire and had to be towed to dealership. When at dealership it was discovered the engine failed. This is a 2024 6.2 liter engine that was not included in recall. I could have caused an accident on the highway as I suddenly lost power. People who were included in this recall received a 10 year 150K warranty on the new engine. My truck should be included in that.

On 1/31/2026, while returning from an AKC event with my XXX year old border collie, I was traveling on IXXX at approximately 70MPH in the left hand lane passing other traffic. As I started up a hill in a remote area, I began to hear a knocking sound coming from the engine compartment that sounded like a rod knocking and the truck began to struggle to continue up the hill. It then lost all power, a message stating to shift to neutral and restart flashed on infotainment screen, I shifted to neutral and pushed the start button, but everything went blank. I had to struggle to merge back into right lane and eventually over to the breakdown lane, approximately 5 miles from the nearest exit. I was forced to remain on the side of a busy interstate for approximately two hours during an unusually cold day for Florida that consisted of snow flurries while waiting for roadside assistance. Luckily, I was able to arrive at the dealership 5 minutes before closing and was able to get my truck checked in. The service writer knew exactly what the likely issue was when I described my ordeal, and it was partially confirmed when she pulled the Christmas tree of codes from the computer that my truck was throwing. It should be noted that the truck would not restart after the catastrophic failure that stopped the motor at 70MPH on the interstate and would not shift to neutral for the tow truck operator to load or unload onto flatbed. Subsequently, Techs determined that engine failed due to suspected internal damage to crankshaft and motor was replaced under warranty along with torque converter. The failed engine serial number was [XXX] but I was never notified or included in current recall 25V274, It did not show as active recall in GM App nor was it inspected during LOF visits at various GM Service departments. My truck was in GM service from 1/31 - 2/21 for the engine replacement, Mileage on 2024 Silverado 1500 High Country was 25,274 at failure.

Transmission failed at 15000 miles. Attempted to shift to reverse and instead car went into neutral. Allowed me to shift into forward but quickly went into “limp mode” once underway. Seems like the same issue as many similar gm trucks have had with transmissions but my 2024 is not included in active recalls when searched by VIN. Suspect it probably should be since issue appears to be the same as those that are.

After engine blows due to recall and engine not running, it is impossible to shift the electronic transmission into neutral mode for towing. This happened to me in November of 2025 and I was recently told that I should report the issue. Neither the tow truck operator nor myself were able to get the vehicle into neutral without the engine running. I could have easily been stuck in the middle of traffic and no one would be able to help me move to a safe location. Some way of easily getting the vehicle into neutral without the engine running needs to be added to all Silverado’s with electronic transmissions.
