I have had an intermittent, aggressive engine knock and rough idle since i bought the truck. I'm assuming it has to do with the collapsing lifter issue from the fuel management system. when I bring it to the dealership (paradise chevrolet ventura) , they tell me that they cannot replicate the issue and that if there is no check engine light on the dash, there is nothing they can do. I am concerned for my families safety and my truck becoming an issue after my warranty runs out. my chief complaint has been documented by the dealership multiple times and I have video of me replicating the issue.

At 383 miles the engine started a ticking noise. Around the same mileage the transmission would also start make hard down shifts, especially into 1st gear. At around 27000 miles transmission would also shutter at light loads and low speeds. Attempted to take it to dealer 2 different times, but they had no loaner cars and needed it for more than a day. At milage 28,251 I drove to the dealership an insisted that it needed to be fixed. They were able to provide loaner car at that time. Engine ticking noise was cylinder number 7 lifter stuck closed. Transmission was unable to be checked due to engine needing repair. The Dealer replace all 8 lifters on drivers side of engine. Upon the fix they test drove for the transmission problem and noticed noise coming from the water pump. Replaced the water pump and was told transmission needed a new valve body. Those parts were on back order for over 3 months. They found a service bulletin to reprogram the transmission so they could release the truck to me instead of hold months for parts. After more than 30 days in shop picked up truck. After driving around for a few hours noticed engine noise again but different. Like a bearing? Dealer had already closed so took it back the next day. Couple days later was informed that the head gasket was installed wrong? REALLY. Went to the dealer's new car manager and asked to be traded out of it and into a new truck. Dealer offered me 10,000 below blue book for trade in! They didn't even want their own product back. Picked up truck couple days later and drove straight to Toyota and traded it in I needed a reliable truck. The dealer's service department was great with the problem. But it's the product that really [XXX] and had the potential to be very dangerous. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On [XXX] around [XXX], I was driving my Silverado down [XXX] near the Cottonwood Mall in Albuquerque, NM. Without warning, the engine died in the center lane of this busy highway. I turned on the emergency flashers, then while trying to call for emergency help on my phone, I stood behind the truck, waving traffic to the side lanes in an effort to prevent being rear ended. After about 10 minutes, luckily, an emergency fire department truck spotted my distress and doubled back, parked behind me and engaged his emergency lights. A good Samaritan stopped an attempted to toe strap me to the shoulder of the road. However, the poor design of this truck didn't allow me to put the transmission in neutral unless the vehicle is running. So, after about an hour, the tow truck driver was able to drag the Silverado on the back of his flatbed. After my truck was at the dealer for a week, they were able to determine that the engine main bearings seized and spun a couple of rod bearings. This is a well maintained vehicle, with the oil changes done on time and documented at the dealership. My Silverado has a 6.2 liter V 8.engine with only 21,532 miles on it.

While driving my 2023 Chevrolet Silverado ZR2 with the 6.2L engine (approx. 22,000 miles) on a busy interstate in another state, the vehicle suddenly lost power and shifted into neutral without warning. I was towing a 5,000-pound camper and had my wife and three children in the truck. We were traveling on a slight incline when the truck unexpectedly disengaged. There were no warning lights, no messages, and no sounds indicating engine failure—just a sudden loss of drive. All displays remained illuminated, but I had no power to the wheels. By the grace of God, I was able to maneuver to the median before the truck and camper came to a complete stop. It was a terrifying and dangerous situation that could have resulted in a major accident given the speed of traffic, the weight of the trailer, and the total lack of warning. The truck was towed to a Chevrolet dealer across the state line. After running diagnostics, I was told the engine had failed and would need to be replaced under warranty. However, I have yet to receive a clear explanation of what exactly failed internally. I was informed that a replacement engine is back-ordered by several months, leaving me without a vehicle and unsure when it will be repaired. The incident has not yet been investigated by the manufacturer, insurance, or law enforcement. This experience was frightening not just because of the mechanical failure, but because it happened with zero indication. I hope others don’t have to go through something like this. I understand thousands of these trucks may never see a failure like this—but for us, it happened suddenly, with our entire family on board, and it nearly ended in disaster.

The symptoms since the beginning of 2024 have been that when braking between 7 and 10 mph, you feel a bump or a skid, and when you stop, the engine shakes for a moment as if it's going to shut off. This happens with the Auto Stop-Start off. A sudden braking moment can affect the vehicle's performance, making it difficult to control and increasing the risk of accidents, especially when it comes to a pickup truck that may have a trailer with cargo or objects in the bed that can be thrown. The trailer can even leave the road, losing control of the car. In 2024, I took the truck to the place where I bought it, Bomnin Chevrolet Dadeland, for a checkup. I explained all the symptoms to my advisor, just as I do here. I had to take it to wait for a loaner. A few days later, I took it back, and they had it for almost a week. When I picked it up, my advisor told me everything was fine. When I left the dealership, I found the same symptoms, so I went back and told him the car was still doing the same thing, and he told me it was normal. After much insistence, he got in the car with me to show him the problem, and the car did it several times, but according to him, it was normal. Now, in 2025, a week ago I took it to Miami Lakes Auto Mall to get checked out with the same symptoms and explanation. I started investigating why that couldn't possibly be normal car operation. They found they had to replace the torque converter and valve body because they found an excessive amount of metal in the transmission. The valve body is on back order indefinitely at all dealerships, so I had to take the car in that condition. Before taking it, I spoke with the manager and GM to ask them to give me a car until they fixed mine because it wasn't right for me to drive the car like that. But they didn't offer me anything. I took it back to Bomnin Chevrolet Dadeland and they told me they were going to change the transmission and torque converter and conveniently they didn't have to change the valve.

I was on Expressway with the cruise set on 72 Miles an hour I heard a loud clunk the engine, of course shut off I go down to the gearshift in the console. It said neutral so close it over to the side of the road got stopped as soon as our momentum stopped and we are completely at a standstill the truck put itself in park. I then tried to restart it and it wouldn’t do anything. I contacted OnStar state in my situation and after multiple conversations with them, I disconnected the phone call and contacted my own towing service because we were 51 miles from our home and they would not tell the people there unless I paid for over half of it. They would only tow it to the nearest dealer. We have been a free customer since 1997. We or a family owned Electrical contacting business. My truck is my office. I’m in 90% of my day. I elected to take it to the dealer where we purchased it, and we purchased a good portion of our vehicles over the years and helps that it would be repaired in a timely manner.

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.
