2023 Chevrolet Silverado 1500

2023 silverado 1500 ZR2 19000 miles,motor shut off going down the freeway pulling my sxs at 70 miles an hour no warning nothing alarm nothing.my wife and i were scared to death trying to get off the freeway pulling a trailer and not knowing if the truck would make it.people around us beeping there horns with flipping us off,no warning.300$ to get my trailer toed back home.dealership tells me they don't have a loner but would give me a voucher.i have been trying to trade out of the truck after hearing about the truck problems 6.2 is a bad motor i new it was just a matter of time. now i am stuck.the scariest part was the timing could not have been worse coming off the freeway.how do i know even when it is fixed it will not happen again.then we could not get the truck in neutral to toe to dealership so they dragged the $80.000 truck on to the toe truck nice.

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.

On [XXX] I was driving @ 55 MPH. The engine made a loud noise, and completely lost all power and controls. Truck went into natural, all dashboard and screens went black. One I was able to come to a stop the vehicle put itself in park. Truck was towed to Jim Butler in Fenton, MO. I was told by the shop that the 6.2L engine in my truck had a catastrophic failure and needed a new engine. The complete and sudden loss of power and controls put myself and others in danger. No lights or warming of the failure about to happen. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

February 9 2024 I was driving down the highway at 65 mph and went to switch lanes and realized engine was no longer running. I pulled over and got a tow to the dealership I purchased it from . Truck only had 5000 miles on it and they told me the engine locked up and needed replacement. They performed an engine replacement. It was not completed until April 6, 2024. Two months to get repaired. Today I was driving down the hightway and again engine blew. I heard a spun bearing noise from engine compartment area. Pulled over and engine shut itslef off . Had it towed back in to find out I am on a line of a bunch of 6.2 engines needing replaicing. Very disappointed in Chevy.

My truck, which has a 6.2 V8 L87 engine, seized up on the highway while on a road trip. The engine suddenly died with no warning or alerts on the dash. The mechanic told me that the oil pan was full of metal and the engine was completely seized. The engine needs to be replaced entirely at just under 40K miles. I have been diligent in taking the truck in for regular service at the dealership, and I had no indication of any problem with the vehicle until it died on the highway while traveling at 65 mph.
