2026 Chevrolet Silverado 1500 engine problems

“Driving on I-64 approx. 75 MPH, I heard a noise coming from what seemed to be the engine; sounded like a belt or hose whipping in the wind-did not sound metallic in nature. I turned off radio and opened window and could not determine source. Within 20 seconds or so, I had lost motive power and vehicle began slowing down, despite applying gas pedal. I did not have any warning lights. Oil pressure seemed okay, RPM stayed just under 2k. Once vehicle slowed down from 75 to about 60 mph I steered vehicle off roadway. I turned off engine and opened hood to inspect. I had light smoke coming out of air filter. Oil was pouring out the bottom. Only then did I have a check engine light on and vehicle would not restart. Dealer inspection determined what I suspected (from previous years 6.2L recalls), thrown rod through the engine block. The service rep said he personally saw the rod sticking out the side of the engine block.”

“Engine Seized. Truck wouldn’t shift to neutral to be towed. Tow Truck with Dollies had to be called. Blocked/Detoured traffic for six hours at the main entrance to CMH AirPort Construction Parking. Yelled at by Security on site to move truck. Absolutely Humiliating.”

“While driving home from work, I pulled up to the stop sign at the end of the exit ramp. When I released the brake and pressed the gas pedal, my truck would not move. This immediately put me in an anxious state as I was expecting the vehicle to move. I checked my rearview mirror to make sure that there wasn’t anybody coming up behind me and put my flashers on while I tried to figure out what was going on. My eyes moved to the shifter next. I noticed that the vehicle was in park. I reached down to the shifter and tried to put the vehicle in drive, but it would not shift. I then hit the push-to-start button to restart the vehicle. After this, I was able to shift back into drive and finish my commute home. This was an unsafe condition as I experienced an unexpected loss of power. An approaching vehicle would expect me to be moving when the road is clear in front of me. I took the truck to the dealership the next day. My vehicle was repaired under warranty. The cause states "update 2810275 Serial Data Gateway Module Reprogramming with SPS." I did not notice any warning lamps or messages, but I also did not look at the instrument panel when this happened. My first…”

“At time of incident this truck had about 5500 miles on it. Prior to this incident, I received no warnings, messages, and experienced no adverse symptoms. I was towing an 18ft Fleetwood Pioneer travel trailer. While traveling at about 70 mph, and climbing a mild grade, the transmission shifted down, and shortly after the engine started loosing power. RPMs remained constant for about 5-10 seconds, but speed was dropping. Then RPMs fluctuated for about another 5-10 seconds. Then no response to accelerator after that. Upon pulling over, LOW OIL PRESSURE message appeared, then ATTEMPT ENGINE RESTART. Upon attempting restart, could hear some pretty weird noises but engine did not restart, and I aborted start attempt. Dealership has ordered a replacement motor under warranty. I was stranded on a narrow shoulder of the freeway for about 1.5 hours awaiting a tow truck. Vehicles sped by at 80 mph which compromised safety, especially when tow truck arrived and he worked on hooking up.”

“I took my truck and atvs from Ohio to Michigan for vacation. We took my truck out. We swerved to miss a deer. Pulled over to check everything out and the truck shut down and would not start. Called roadside assistance, they towed vehicle to a Chevy dealer. Dealer calls me later that afternoon telling me the engine locked up and needed replaced. The truck had 5,800 miles when this happened. We were also traveling at low speeds. If this had happened on the freeway it may have caused a serious accident and may have resulted in injury or loss of life. Since they replaced the failed engine with the same engine I am concerned it will do this again and have no confidence in this vehicle.”

“Driving on [XXX] in Maryland, engine just stopped. Pulled to the shoulder. Engine refused to start. Was towing a 7300lb Airstream Flying Cloud trailer. If unable to pull on to shoulder, would have been stopped i the slow lane of the road. Weiner Chevrolet in Cumberland, MD. Has confirmed that the engine seized up. They are replacing the engine. There was no indication of anything wrong till the engine stopped running.”
