2020 Chevrolet Silverado 2500 Power Train

Pulling out onto road, heard a bang, no forward or backward, unable to move vehicle, brought to repair shop, says output shaft is sheared off, 68000 miles on it, looked on line, apparently common defect, my son in laws friend just had his happen getting off ramp exit, 80000 miles, I’ve read where low as 20000 miles, as well as 59000, 33000 ridiculous crap made in USA…. Please help! No repair as of yet.

10L1000 transmission, began having problems with delays and harsh gear engagement. Flare shifting and shuddering. Finally starting having transmission overheating issues while towing. I had to make several unsafe stops with a trailer to wait for the transmission to cool down again before continuing to get it home. Saw trans temps up to 240°F on flat land with 40° outside temps. I could smell the hot transmission fluid inside the truck. When I went to check the fluid level of the transmission, the fluid was full but had a large amount of glitter like metallic flakes. The fluid was very dark brown in color and smelled terribly burnt. The last recall I took in to the dealer for was about the transmissions possibility of failing, locking up, along with the rear wheels at any speed. I have young children that ride in this truck, that in it self was unsettling and unsafe. But then to have issues with absolutely no warning light was concerning. Ive since ordered an aftermarket built transmission to avoid repeating the same issues with a factory GM replacement. My factory warranty had also ended a few months prior to having these problems with it. Leaving me to completely foot the bill for it to be replaced. I had to pull money from my retirement early to cover costs, in fact costing me much more than just the sticker price.

Transmission valve body issue

While driving the truck it will have a hash upshift which has happened on five different occasions plus on two other occasions after first startup and drive the transmission will not shift out of third gear it will just wind up the RPM's as if transmission is stuck in third gear. I have to let off throttle then accelerate and back-off a couple of times to get transmission to shift out of third gear. The software upgrade is not a fix for this recall as it does not address the problem. The valve body installed in these ten speed transmission is a manufactures design flaw along with using inferior parts required for the safe operation of this vehicle. There are documented claims of the valve body failing causing catastrophic failure of the entire transmission and GM Corporation will only cover the valve body. GM has told it's customers that they will warranty the VB only that the other damages are not covered. The recall letter I receiver indicates that only the VB is covered. This is unacceptable. It is because of the VB failure that the transmission will suffered catastrophic failure, Without a properly functioning VB the transmission cannot receive the lubrication it needs to function properly. I have not had the software update as their are reports of customers trucks going into limp mode shortly afterwards. Their trucks are then parked on dealer lots as parts are currently unavailable for weeks at a time in some cases months. These customers use these truck for their livelihood and they invested a large amount of money purchasing these trucks only to be told So sorry GM will not cover your claim even through it was our defective VB that destroyed your transmission. These trucks are not cheap to purchase nor to properly maintain.

Def tank heater. I had one replaced @ 24K and another replaced 47K

1. Transmission recall N242454440 Chevy 2500hd Diesel Silverado 2020yr. Jan 2025 valve body inside transmission was replaced, recall pending, parts not available, NOT DONE. 2. Currently having this issue but no recall information found for my Vin...The "P22F9" engine code on a 2020 Chevy Silverado 2500 diesel indicates a recall related to the NOx sensor, specifically a "slow response" issue with the sensor, which the Engine Control Module (ECM) might not properly detect; this recall requires a software update to the ECM to address the problem. Key points about this recall: •Affected vehicles: Primarily 2020 Chevrolet Silverado 2500 and 3500 trucks with diesel engines, as well as similar GMC Sierra models. •Issue: The ECM may not accurately identify faults with the NOx sensor, potentially leading to emission issues and reduced engine performance. 3. P1089 fuel deceleration problem, several repairs were done but problem still persists. GM engineer's told dealership having problems with computer duplicated codes in memory. Engine light goes on and off over 50,000 miles, vehicle runs great and no gas found in oil. At one point engine light was off for 14,000 miles. *P1089 should definitely be a RECALL ITEM! MISC: Yes available for inspection. No safety problems as of yet. All repairs were done at dealerships and confirmed by dealership. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? NO * I have contacted GM management staff in Michigan Mr. Craig Gidden, senior executive liaison, which referred me to CA customer service and supervisor, all to no avail, absolutely horrible customer service! They did not want to provide their contact information etc. *Contacted the GM arbitration department, they provided a case number but will not provide or respond to my emails for supervisor and GM legal department information.

We received a recall notice 4 weeks ago on our Chevrolet Silverado diesel truck. VIN:1GC4YPEY0LFXXXXXX. The National Highway Traffic Safety Administration Campaign 1D Number for this recall is 24V797. We can not get any answers from GM as to when it can be fixed. We use this truck for heavy towing constantly. We do not want to be in harms way. Can you help resolve this problem?

The Transmission Oil Cooler line separated at the crimp joint from the rubber hose to metal pipe. This sprayed trans fluid all over my hot exhaust(fire risk) and caused and immediate loss of propulsion as I was accelerating to merge onto the highway. I was lucky enough to have multiple vehicles swerve to avoid hitting me. This defect left me on the side of the expressway.

Truck on its own Shift from Park to Drive on its own while at idle. Summary: My 2020 Silverado 2500HD was in the driveway idling in Park. The vehicle was empty and I was checking the garage for screws from a project I had just completed and I wanted to make sure they were all picked up before I parked the truck in the garage so that I did not get a flat tire. After looking for screws and assuring myself everything was cleaned I proceeded into the third bay of our garage and right behind me by an inch the truck proceeded into the garage at a good rate of speed and crashed into the house. I quickly ran through the third bay and to the vehicle as it was still wanting to proceed into the house. I quickly shifted it into Reverse from Drive backed up about 2 to 3 feet and placed the truck back into Park again and placed the emergency brake on and shut the truck off...
