The tail gate on my 2023 Silverado has started to open on its own both while driving and while stopped as well as attempting to open every 3-5 minutes while the vehicle is off. I contacted Chevrolet after I saw there was open recalls for this exact issue to see if my truck was covered with this recall and to my chagrin it is not. But from what I read, this is the exact issue that other drivers of Silverados between the years of 2020-2024 have been experiencing.

On 3/1/2025, while driving, my vehicle became unresponsive and inoperable . My vehicle stopped at the intersection in a turn lane. The vehicle engine turned off and a check engine light turned on in the dashboard. There were no sounds or indicators prior to the event. All of the controls became inoperable and unresponsive. When I tried to restart the vehicle it would not turn over. I was unable to shift the vehicle out of park. The dash board showed the message “Conditions Not Correct for Shift”. I tried several different corrective actions and referred to the owners manual but I was unable to do anything. The owners manual didn’t specify how to shift the vehicle when it is not running. I had to call a tow truck because we were in the intersection and it presented a concern for safety for ourselves and others the tow truck tried resetting the vehicle, jumping it, and looked for the manual shift override but were unsuccessful. They pulled my truck onto the tow truck and took it to the dealership where I purchased the vehicle. When we arrived at the dealership the tow truck driver consulted with the dealership personnel and were still unable to determine any cause or how to manually shift the vehicle into neutral. My truck has the 6.2L V8 L87 gasoline engine with only 15466 miles. The dealer confirmed engine failure and is in the process of ordering a new engine. There is no known ETA for the engine because it has become a national issue. I have also read multiple encounters of other owners have multiple engines fail and replaced.

I was driving on the highway at about 65 mph, when all of the sudden the truck shut off. There was construction in that part of the highway and there was no shoulder for me to drive off to so I kept driving until the truck completely stopped on the highway. I had to jump off the truck from the passenger side with my wife and toddler and jump the median and stood there in the cold for a few hours while a tow truck came to move the truck out of the highway. We did not fell save staying in the car because there was a lot of traffic and we were afraid to get rear ended. I got the truck towed to my house which cost me $600, the next day i called the dealership to come pick it up. They took it and found the engine was completely damaged. They replaced the engine, but with the same engine model that has the defective engine that NHTSA is currently investigating on these engines. So i no longer feel safe nor can i rely on this truck to run my business.

Traveling at ~40mph when some knocking could be heard. Pedal manipulation was intermittent. No warnings on the dash. Luckily, I was able to use momentum to get the truck off of the main road and onto a side street. Knocking was heard even louder now - pedal manipulation was now even more intermittent. An error message popped up on the display "Conditions not correct to shift", with no other lights coming on. Truck has now coasted to a stop and the check engine light came on. Cannot put the truck into any other gear. I was lucky enough to not be traveling at a higher rate of speed, but I can see this being a huge safety concern. The truck was towed to a local dealer where i was told that the truck has experienced "Spontaneous Engine Disassembly". However, my service record only states "Check Engine Light On". The attached information is the only thing that I have of the incident and how it's being reported.

While pulling out onto a very busy highway in North Dallas, I had to "step" on it in order to make the turn. Immediatley after making the turn I went to "step" on it and the truck shifted into Neutral with heavy traffic. Luckily I was able to coast to a turning lane safely. Once stopped I was able to place the truck in park. However, after shutting off the truck it was never able to restart. This night was an extremely cold night with subfreezing temperatures. Not being able to start the truck meant no heater and myself and my girlfriend quickly became very cold. After calling OnStar we waiting almost 45 minutes for roadside assistance. However, they were only coming to try and jump start the truck and had to request a second roadside assistance to come and tow the vehicle. The vehicle could not be shifted into Neutral and a flatbed truck had to be used and the truck had to be drug up onto the tow truck. When I first stopped the truck and shifted it into Park, the engine was still running and sounded normal. It just could not be shifted into any gears. However, the GM dealership is telling me the engine seized up and needs to be replaced and could take 4-8 weeks just to locate an engine. Although no one was hurt or injured thankfully, the safety risk when this happened could have been very bad and deadly. Not to mention not being able to have heat during extreme cold temperatures is a safety concern. Had the truck not been able to be parked in a safe area, and not being able to be shifted to Neutral, this also could pose a safety risk.

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement.

The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation.
