2020 CHEVROLET SILVERADO 2500 Complaints

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.

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?

In 2024, I noticed that my truck was experiencing rough shifts. It felt as if the back wheels were jerking over uneven ground, even though the vehicle was on a flat surface. In November 2024, my sister sent me an article about General Motors' massive recall due to rear wheel lock-up, which increased the risk of crashes. I contacted GM and learned that my truck was part of the recall. I reported the issues my truck was exhibiting, and GM instructed me to reach out to my dealer about the problem. However, I was informed that they did not have the parts to fix the issue and had no idea when they would receive them. I asked GM if they would provide me with a rental vehicle, but they declined, stating that if they offered a rental to me, they would have to provide one for others as well, which was not feasible due to the large number of affected vehicles. I explained that my truck is my daily driver for work, and I frequently transport my grandchildren in it. Driving the truck was hazardous given the issues it was already exhibiting. I was told to contact my dealer, and since my truck was under warranty, they should provide me with a rental. When I requested to speak with a manager, I was informed that they would only reiterate the same information. I then contacted my dealer, Sapaugh GM Country, located at 1435 McNutt St., Herculaneum, MO. I was informed that they do not have the parts. but they did a minor tweak which has caused more damage to my powertrain and engine.
