Subject: Engine Failure – 2024 Chevrolet Silverado 1500 (6.2L V8 •VIN: [XXX] Issue Description: While driving on [XXX], I noticed the transmission would downshift but not upshift. Within seconds, a warning appeared: “Oil temperature high, idle engine.” I began merging onto the shoulder, but before I could get there, the engine shut off completely, and the transmission shifted into neutral. After coasting to the shoulder, the transmission shifted into park on its own. Failure to Restart & Electrical Issues: I attempted to restart the engine, but it would not turn over. The dashboard, radio, and electronics turned off for a few seconds before coming back on, but the engine remained unresponsive. Towing Difficulties & Roadside Assistance Failure: GM Roadside Assistance said no contracted towing companies had the equipment to tow my truck because it would not shift into neutral without the engine running. I had to find and pay for a tow truck myself, with no guarantee of reimbursement. Dealer Response & Repair Delays: My truck has been at the dealership for days, but they have not started repairs due to technician shortages and a backlog of work. They stated: •Manually cranking the engine is nearly impossible. •The starter is not strong enough to turn it. •Repairs could take months. Loaner Car & Additional Hardships: Per the GM warranty, I received a loaner car but must return it every 500 miles. Since I commute 160 miles per day, I must frequently exchange it, causing major inconvenience. Safety Concerns & Requested Action: This sudden engine failure on the highway was a significant safety risk. Given that NHTSA is investigating failures of the GM 6.2L V8 (L87), I believe my case is related. GM should issue a recall or extended warranty for affected vehicles.

The vehicle had a sudden engine failure driving up an incline and a bearing rod caused me to need a new engine. It’s at Myrtle Beach Chevrolet and they tell me the engine is on National BackOrder. It’s a new truck and now needs a new engine that can’t be found. Shame on GM

This is the 3rd engine failure in 23K miles. The first was a Lifter/Rod problem at around 3K miles. The 2nd was catastrophic engine failure due to a spun bearing at 21K miles. Now at 23K miles, I'm having another catastrophic engine failure with the same issue. Engine is the 6.2L L87.

When Driving my 2024 Chevy Silverado with 24,600 Miles on it this morning, i was on the New York State Thruway going highways speed (70MPH) when the truck Lost Power, and Shut completely off, I had a tractor trailer behind me and lucky my pick up truck was able to coast over the white line, if i would have been able to coast over the white line i would have been in a major accident. I attempted to start the truck up again and the truck would not turn over, i had sat there for about 25/30 Min trying to get the truck started and finally the truck turned over and i was able to continue on to work, While driving the truck had absolutely no power and the truck was sitting around 3K RPMs when going 66mph, the truck was hard shifting into gears as well. I arrived at work and i got to a parking space and all the sudden the truck shut off and wouldn't not start back up. Upon arriving to work i rolled down my window and heard a long banging noise coming from the engine Aswell as a whining noise. I attempted to start the truck up and you hit the start button the truck just keeps whining and never starts up. I was able to contact GM Roadside and have a tow truck come and pick the truck up and bring it back to the dealer. Im awaiting the dealer to contact me. Overall, i could have been in serious car accident for because the engine just shut off on the highway, this happened with no warning or anything, the check engine light was NOT on before this happened.

On 12/24/24 my truck went into limp mode with the notification of “reduced acceleration” nearly causing an accident. Luckily I was able to get off the road to safety. The truck wouldn’t go in reverse or fully accelerate. I had the truck towed to the dealership. The dealership informed me it was the Valve Body in my transmission. They mentioned they have 4 other trucks with the exact same issue. It’s been 1 month since and nothing has been repaired and GM has not responded to my inquiries on a replacement, update on the part, or a buy back. The vehicle was brand new on a lease only 7500 miles on it and was purchased in July. The truck didn’t even last 6months. Had I not quickly gotten the truck off the road I could have been T-Boned and could’ve died at the intersection by a semi coming through. The fact this vehicle was sold, while this was an issue is criminal negligence.

My 2024 ZR2 has roughly 22,000 miles on it. Was driving and lost power. Dealership actually sent someone to come look at my stalled truck. Would not turn over. Dealership got it towed. After diagnosis, they said the engine had seized. This is absolutely uncalled for on a brand new vehicle that I paid over $70,000 for. This exact same thing happened on my Co Workers 2020 high country 6.2. It is currently being worked on, and now seeing that over 877,000 of these 6.2 engines have done this exact same thing since 2019??? How is this engine still being put in these GM vehicles? Now they are going to put new or rebuild the one I have that the exact same thing can happen to the new one? No new warranty will be given as I just get the remaining warranty? I'm sorry but this is the most expensive vehicle I have ever purchased and was proud of it. Now I have a ticking time bomb? I work out of state and if this happened while out of state, what do I do?? I would like action taken! I am getting an attorney involved as this should be taken care of after 877,000 vehicles. What other action can be taken?
