Transmission went out while driving on highway, entering limp mode. Ended up needing a valve body replacement at only 20k miles which was covered, but now I am having more transmission issues still with delayed forward engagement and slipping gears and it is only at 65k miles. Seems to be a lot of customers having the same issue. Took months for the truck to be fixed as "many other trucks" were waiting on the same part according to dealership.

Transmission has jerked/bumped in past and now at approx 85K miles, it supposedly needs a new transmission. I've heard it is a pretty big issue and seems llike relatively low mileage for this to be happening to 2023 year model. I certainly don't drive it hard and rarely tow or haul heavy loads.

Valve body in the transmission failed while driving on the freeway, all of a sudden it was like the car was in neutral and the RPM's went to redline. Dealer is telling me it is a known issue and has no idea on when they will be able to get parts because they have been on backorder forever. Says that they also have to replaced the Transmission Control Module (TCM). same thing no eta on parts. If this is a known issue why have they not recalled them. Fom what I see on line this failure is happening a lot to people, hence the unavailability of replacements parts.

I am writing to formally document a series of catastrophic mechanical failures involving my vehicle, as well as serious inaccuracies currently reflected on the Carfax report. At approximately 15,000 miles, my vehicle experienced a catastrophic engine failure that required a full engine replacement. Less than 900 miles after the engine replacement, the vehicle then suffered a catastrophic transmission failure, which also required replacement. In connection with the transmission failure, there was also a fuel module issue that left me stranded. These failures were not minor or routine service events. One breakdown occurred on a major roadway and required the road to be shut down due to the vehicle being disabled. Another breakdown occurred on the Florida Turnpike as a result of complete engine failure, leaving me stranded in a highly dangerous situation. Despite the severity of these events, the Carfax report does not accurately reflect what occurred. The Carfax report does not state that the engine was replaced, and the transmission failure is not identified as a transmission replacement at all. Instead, it is reported as routine or normal service, without any indication that a catastrophic transmission failure or replacement occurred. This misrepresentation significantly understates the true condition and mechanical history of the vehicle. Due to the repeated catastrophic failures, the circumstances under which they occurred, and the risk posed to my safety and the safety of my family, I am genuinely afraid to drive this vehicle. I want to ensure that all of this information is properly documented and that the vehicle’s records accurately reflect its true history and condition.

The 2023 Chevrolet Silverado 1500 High Country has experienced multiple powertrain and transmission failures beginning shortly after purchase. The issues include violent shifting, hesitation, and stalling, particularly while accelerating or decelerating. These malfunctions create serious safety risks—especially when merging, turning left across traffic, or entering intersections. The truck has been returned to authorized GM dealerships multiple times for diagnostics and repair. GM service departments confirmed transmission faults but have not successfully resolved the issue despite repeated attempts. The same problems reoccur shortly after each repair. At times, the vehicle has entered “limp mode” unexpectedly while driving, causing a loss of power. On at least one occasion, this occurred while driving on a busy highway, forcing evasive action to avoid a collision. Warning lights such as the “check engine” light and service alerts frequently appear before or during these incidents. To date, the vehicle has been inspected by GM-certified technicians at authorized dealerships. A case has been opened with GM customer care and BBB AUTO LINE arbitration has been initiated. The truck remains unreliable and unsafe to operate, especially with children on board. The risk of sudden power loss or drivetrain malfunction poses a clear hazard to occupants and other drivers.

The fuel pump went out, left me stranded and was replaced The transmission went out and was replaced. The lifters in the engine were replaced. When will the engine recall be addressed/acted on? The "cure" to install heavier engine oil is a very bad "bandaid"....truly masks the problem. Maybe the Chevy CEO should return her 2024 $25mm bonus to help pay for the repairs.

2023 Silverado 1500 3.0 Duramax. Transmission failure and engine overheating at 5k miles. I was towing a trailer when the 1st transmission failure occurred. The engine shut off, and said shift to N to start while coasting with loss of power braking. I was able to get started but transmission would slip when shifting above 1st gear. I had to tow to the nearest level point to safely park the vehicle, for fear of rolling backwards down 8% grade. At that point the computer was showing engine overheat loss of power warnings. GM roadside assistance towed to nearest dealer, refilled transmission with fluid, and put me back on the road for it to fail again in traffic (loss of power / unable to move). I have now been without vehicle going on 30 days and worry there is more wrong with the vehicle than just a blown transmission (latest GM diagnosis with no repair eta). For a few hours prior to failure I noticed what seemed like the transmission hunting for gears at lower speeds (0-25) with hesitation. Could have been slipping. And also noticed strange / louder than usual turbo noises. I worry the system is generating too much pressure or has mixed oil with coolant somewhere, based on finding atf, coolant, and engine oil near the overflow and all over the bottom of the vehicle. GM support has been atrocious and someone should step in.
