2024 Chevrolet Silverado 2500

While driving the vehicle, the vehicle jolted and made a clunk noise. The check engine light came on accompanied by a message on the Dash stating "Reduce acceleration, Drive with Care". The vehicle went into "limp mode", and appeared to be engaged in a single gear. The vehicle was traveling at approximately 30 mph when the transmission malfunctioned. The vehicle was taken to my local Chevy dealer, where they scanned the vehicle and determined that the Valve Body was the issue, based on the scan result. The vehicle is a 2024 Chevy Silverado 2500HD (Gas). It has 29k miles on it. The vehicle was purchased as a "certified Pre-owned" (lease return). Within 20 miles of being driven from the dealer after purchase, I experienced a jolt & clunk. The failure occured 42 miles later.

Batteries being drawn down from a parasitic draw. Tailgate won’t operate from outside the truck and infotainment system malfunctioning also lights flashing periodically. This is the second time in about a month this has happened. The first time the dealer said I had bad batteries so I replaced both of them with Napa batteries. Waiting to hear from the dealer now on the findings this time.

While driving in heavy interstate traffic on March 18, 2026, the vehicle suddenly downshifted hard to 2nd gear, locking the rear wheels and causing the vehicle to slide out of my lane. The truck then entered limp mode and appeared to be stuck in 2nd gear. I immediately called my chevy dealer to make an appointment to drop the truck off. While researching, I found there was a recall for the same vehicle symptoms, but my truck falls outside of the recall. The truck is currently at the dealership for a valve body replacement, due to a KNOWN issue with the Allision transmission where TSB's have been issued. Chevrolet should be more proactive and recall the trucks, and replace the transmissions instead of a bandaid fix, before someone with less driving awareness/experience is involved in an accident

The contact owns a 2024 Chevrolet Silverado 2500. The contact stated that on two occasions while driving at various speeds, the vehicle went into LIMP Mode with an audible chime, and several undisclosed messages displayed on the instrument panel. Due to the failure, the vehicle was turned off, and the battery terminals were disconnected for several minutes before being reconnected. The vehicle resumed to normal functionality and the warning lights independently turned off after driving for a while. The vehicle was taken to an independent mechanic who discovered several diagnostic trouble codes associated with the transmission control module. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 55,000.

My 2024 Chevrolet Silverado 2500HD Bison ZR2 (VIN [XXX] ) suddenly lost all power steering, acceleration, and propulsion while driving my children to school at approximately 8:00 AM on March 16, 2026. The truck came to a complete stop with no warning lights or prior indication. This matches the exact ‘critical issue with the engine and transmission system’ alert I received from OnStar Advanced Diagnostics the same morning. Steering was completely unresponsive and I had no acceleration. My children were passengers — this was extremely dangerous. I have not driven the vehicle since and have requested towing to the dealer. Please investigate under any open probes into 2024 Silverado HD power-loss and steering failures.

While accelerating to merge onto the highway, the transmission attempted a shift twice and could not complete the shift. That process causes an aggressive deceleration with each shift attempt. It then slowed, turned on the check engine light and displayed "Reduced Power Mode" - i.e. went into limp mode. The dealer pulled code P0747. The repair is a full transmission rebuild. I did not experience wheel lock up like other people have, but this is the same problem that has been heavily documented.

When driving, between the speeds of 40-50mph, the wheels would lock up without warning. This happened 4 times during the month of January, sometimes in 4wd. This occurred at speed when the vehicle seemed to be upshifting. Control of the vehicle would be lost during the lockup as the wheels would stop rotation entirely and rather violently. Check engine light came on after the 4th incident, reducing power and a code of P0747 "Pressure Control Solenoid "A" Stuck On". The transmission valve body was repaired by the local Chevrolet dealership under powertrain warranty. This is a known issue on previous years of this truck with the same transmission but has not been expanded to cover this vehicle. Thankfully, I was able to maintain contorol and was not in traffic when this occurred. I notified the dealer that the vehicle was shifting very hard during the last visit but no codes or issues were found at that time indicating an issue.

The contact owns a 2024 Chevrolet Silverado 2500. The contact stated that while driving at various speeds, the vehicle entered LIMP Mode. During the failure, the transmission became stuck in 5th gear, and the vehicle operated at reduced speeds. The vehicle was turned off but failed to immediately restart. After approximately 15 minutes, the vehicle restarted, and the failure was self-corrected. The failures had occurred while hauling a heavy load and while not carrying a load. The message "Decreased Acceleration" was displayed, and the check engine warning light was illuminated. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The transmission fluid was flushed and refilled, but the failure persisted. The manufacturer was not yet notified of the failure. The failure mileage was 54,000.

My husband and I were driving his Chevy Silverado with our two dogs in the back. Without any warning or any alert, our vehicle came to a complete stop in the middle lane on a three lane highway. Not a slow stop where there was any time. I’m confirming immediate. At that time, the vehicle would not move at all for almost 5 minutes. As we sat there praying to God that we wouldn’t die as tractor trailers and other vehicles came flying past missing us by inches. It’s truly a miracle that no one was killed. He put truck in neutral and pressed start button and was not able to go any faster then 5 mph and once again a miracle we were able to make it to shoulder of highway without being hit. The vehicle was shaking excessively and flashing things like emissions, traction, as our videos and pictures will show when we made it to side of highway. This is a disgrace that any vehicle would ever be manufactured with this outcome. I am deeply grateful that my husband and I and our two dogs are alive and not injured but this should NEVER happen again.
