The contact owns a 2026 Chevrolet Silverado 1500. The contact stated that while driving at 70 MPH, there was an abnormally loud pinging sound coming from the engine. The vehicle lost motive power, the brakes and the steering wheel became inoperable. The message "Depress Start" was displayed. The vehicle was towed to the local dealer, where it was initially diagnosed that the battery failure was unsoldered. The vehicle was repaired, but the failure recurred. While being test-driven by the mechanic, the vehicle stalled. After further investigation, it was determined that the engine needed to be replaced due to the main bearing failure. The manufacturer was notified of the failure, opened a case and informed the contact that a case worker, near his location, would contact him in 24 hours. The failure mileage was approximately 9,025.

Purchased truck in May of 2026 from Chevy dealer. Truck had around 1500 miles on it. Within 1 week the truck was shifting, very roughly, for no apparent reason making it lurch. I brought it to a local Chevy dealer, who ran it, showing a fault. I got the truck back from the dealer, who said tech had looked at it, and cleared the "fault" that was showing up. less than 1 week after that, the truck started doing the same thing, and I am bringing it back to the local Chevy dealer this week. The dealer I purchased the truck from said it was a trade in because the owner didn't like the truck. I'm concerned the dealer I bought the truck from may have known about the problem when I purchased the truck, and this may be the 3rd time that the truck has been back to a Chevy dealer for this problem. I looked on line and found Chevy has has hundreds of thousands of recalls on this 6.2 liter L87 engine, and there is a class action suit involving this engine from previous years, as well as hundreds of complaints regarding the 2026 version of this engine.

My vehicle has 3416 miles on it. I was at a stop light, busy intersection, and it just died. It would not restart or go into neutral to push it to the side of the road. I had it towed to the dealership, and found out theres a bulletin on these motors. [XXX] . Why would I buy something when its been a know issue with the manufacturer since 2025. I feel as if the manufacturer is selling these units and once this happens its the consumers loss. I cannot believe the manufacturer has not issued a recall. If that were too happens there would be a lot of lemon laws and there lawyers know not to go down that road. There fix is to give me a refurbished engine!! How can that be constitutional knowing there's been a problem with this engine and now my resale value just went down. If I knew what I know now I would of purchased used because thats what im getting in return which is consumer robbery.
