Had the Motor replaced under recall / warranty at a certified chevy dealer. ~41k miles. 6.2L L87. GRAFF chevy of Chesterton Indiana. After long lead times and getting the run around, the truck was "done". picked it up and many things were still wrong/incorrect. They were able to take care of it. A day later, the truck died in the road. towed to another GRAFF dealer. 2 days later it was found to be a bad ground. fixed. Fast forward ~3k miles later. the transmission went out and locked up on a main roadway. Towed to another dealer (West Herr chevy Orchard Park NY). They found the root cause was due to transmission cooler lines coming loose from faulty installation during motor swap. There were also many other items found that were broken or loose under the hood of the vehicle from faulty workmanship. I am being told it is not covered under warranty because of the previous dealer's workmanship (GRAFF Indiana) I was able to get the truck put of the roadway and to a safe place, but this very well could've caused an accident, and I would like to document it.

Oil cooler failed and truck was at dealer for a month over winter. Now June 20th transmission failed and there is no timeframe on the valve body. I am still making payments on this truck and no dealers have a timeframe.

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.

8 Speed Transmission without any warning, started shaking and clunking and slipping while doing 55mph in traffic causing sudden loss of momentum. 8 speed transmission failure. Dealership says bad transmission control module and won’t inspect internal components. Chevy is still playing games with people with their defective 8 speed transmissions. They have not fixed all of their previous problems

Was pulling out onto the road from sitting at a traffic light, vehicle was going less than 25mph when the engine made a clunk trying to shift and the check engine light came on. Computer software indicated “limp mode with reduced acceleration activated.” Vehicle wouldn’t accelerate above 35mph, had to drive on major highway to get to dealership. Truck is only used as commuter vehicle hasn’t towed anything. Dealership indicated valve body transmission failed with vehicle only have 9k miles on it. Part is on back order as it is being manufactured due to installed faulty part, problem has been going on in 2023/2024 Chevy and gmc trucks since January 2024 without a recall put in place. Problem is being fixed after the part fails and the truck fails to run at optimal valves. According to forums software update were installed versus recalls to the actually valve body part being. I was sold a truck in sept 2024 with a faulty installed part versus it being fixed before it was purchased. This caused me to be stranded 1500 miles away from my home and we were not made aware of the know valve body transmission issue. The information was covered up versus being disclosed.

Valve Body failure at 5,500 miles. Transmission wouldn't engage in reverse. Truck went into limp mode with a reduce speed message. Valve Body is on back order for 7-8 months. The dealership decided to order a new transmission. Ive been waiting almost two months for the transmission to arrive.

The valve body in my transmission went out in Colorado where my truck is currently at a dealership under warranty. They are putting my job at risk due to the fact that I bought that truck specifically for work since I travel all over the country for work. I told them that I need the part expedited because I need to leave Colorado and go to Texas for work on the 28th and still no help at all. All I’m asking for is for the part or a new transmission to be sent and installed before the month ends. Because if it doesn’t I’ll get fired if I don’t make it to Texas. And I’ll state this I will pay out of my own pocket even though the truck has warranty if it means the part can get expedited.

I purchased a new 2024 Chevrolet Silverado 1500 4wd in May 2024 from a Chevrolet Dealer in East Tennessee, after having the truck for 5 months, it started experiencing a transmission "shutter / vibration" at higher speeds, it has also experienced a transmission "hard downshift" at times... a month later at only 4914 miles, it was dropped off at the chevrolet dealership here in my home state of Alabama for its first oil change and for them to check what is going on with the transmission, after the truck being there for 3 weeks, we were told that the transmission needed to come out for repairs, we advised the dealership and several GM representatives that we wanted a brand new transmission put in the truck that is brand new to start with, GM has refused and stated that they were going just rebuild the transmission.... we told them "No" and that we had bought a brand new truck, therefore it should have a new transmission, not a rebuilt one in a brand new truck with less than 5000 miles on it.... the truck has been out of our possession starting into its 3rd month being gone for repairs, not only is this a huge inconvenience for us, but its also a huge safety issue because we do occasionally pull trailers with this truck... General Motors has flat refused any help to our satisfaction with this transmission issue and has just pretty just blown us off and told us "No" when we have approached them with any kind of remedies for this situation, its pretty bad when a company that has taken a government bailout a few years ago, hasnt learned anything from their past mistakes and now think theyre untouchable.... it also pretty bad when you spend in excess of $60,000 for a pickup truck that you dont even have in your possession because of defective manufacturing.... yes, it is a safety issue even more because my family is sometimes using this truck and may not always react the same way that I would if something happened going down the road.... it needs a recall on these trucks

On 1/13/25 while driving my new vehicle and arriving at destination I placed vehicle in park for 10 mins and then left putting vehicle in reverse and transmission in reverse would not engage, rolling me into decline slope and almost crashing into home. After receiving help to push vehicle in neutral, I placed car in drive and sent to dealership. Truck seemed fine in drive. Parkway Chevrolet, Tomball, TX inspected vehicle and stated no issues. Possible torque lock but nothing showing and possibly resolved. On 1/16/25 while driving to work, I stopped at gas station for coffee, left truck running. Got back in vehicle and placed in reverse, and again truck would not engage reverse. I received another push out in neutral , placed in drive and then proceeded to return home. While I’m drive check engine light came on, and truck would not go beyond the 2nd gear. I stopped at closest light to turn around and proceed home and the vehicle began grinding gea and jerking my vehicle while in drive. I tried to turn around at a dead end road and could not reverse vehicle and called for tow to dealership. Dealership at opening 7am took in vehicle 2 nd time with my complaint and called at noon. They stated the valve body of transmission needed to be replaced. Further stating it was a faulty issue chevy was aware about but nothing showing and recalled. They said no longer using manufacturer for this transmission replacement and it would be an unknown eta for repair. This is dangerous and unacceptable as it is a new vehicle with a known faulty part.

Valve Body on transmission failed at 9000 miles resulting in extreme reduced acceleration and it being unsafe to drive. No warning lights appeared until after the part failed. Failed valve body has been confirmed by the certified dealership service center. Replacement valve bodies are unavailable from the manufacturer GM. GM has not issued any formal recall for this part and searching online forums, this is a very common part failure for this vehicle.
