2026 CHEVROLET SILVERADO 1500 Engine Problems

Truck has 2600 miles. driving down road at 55mph and heard loud squeeling noise coming from front of truck, lost power and knocking noise coming from engine. towed to dealer and needs complete engine replacement.

At about 800 miles i noticed ticking from the engine and random and intermittent jerking. Some of which were very severe that felt like someone rear ended me. I took into the dealer with my complaints. They kept my vehicle for 2.5 days and didnt give me a loaner. The my were unable to reproduce the jerking and said the ticking was normal. They showed me the ticking and said its normal and will go away after it warms up. They did a vehicle update and said it will help. They said theres nothing else they will do. I knew something was still wrong but felt like they wouldnt do anything and I couldn't give up my vehicle for days at a time. I continued to drive it and was planning on taking it to a other dealer for a check up. But at about 3500 miles. One day the...

At 4400 miles on new truck started a random cylinder misfire which engine jerking and causes ESC, Emerg breaking and adaptive cruise control to turn off. Will reset itself then do it again. Little over 100 hours on new engine. It happens on longer trips on of off the highway.

On Tuesday 01-20-2026, I was driving from Dallas Fort Worth to Oklahoma City, OK. I was driving down the highway I-35 at about 80 mph. Suddenly I felt a loss of power and my truck started to bog down. As I pulled over, the engine stalled out and would not start up again. It would crank but it would not start. My truck was towed to a dealership in Norman, OK. "Landers Chevrolet". I was contacted by the dealer the morning of 01-21-2026 informing me that my engine is going to need replaced. My truck is a 2026 Chevrolet Silverado LT Trail Boss with 6.2L and 6,457 miles on it. At this time, I don't have any paperwork or a copy of the repair order because the vehicle is still in the shop. The dealer told me that the motor is on order and should be here in 4-6 weeks....

Vehicle has less then 700 miles. Upon driving vehicle, the dashboard started losing information, no speedometer. When I tried to pull the truck over to the side of the road, the power steering was lost. It was nearly impossible to turn the wheel, then the engine stopped. I was unable to turn on blinkers or hazard warning lights. When I put the vehicle in park to try a restart the engine would not turn over. The transmission was locked in Park and unable to shift to neutral to try to push vehicle to safe spot. At this point I was blocking the road. Called for roadside assistance, two hours later vehicle was towed to Chevrolet dealership, were it is being assessed.

November 28th 2025 we were coming down Logan canyon in Utah at 50 miles an hour when i was passing another vehicle on the left I felt a hard shift and a prompt came on the dash that said reduced acceleration. So as I was passing the vehicle I was pulling in front of them and lost the ability to accelerate or even hold speed. I passed the vehicle got in front of them and slowed down rapidly without any ability to control the speed of the truck. At this point when I would push the gas nothing would happen so I pulled off the side of the road. While we were sitting, there was suddenly a burning smell in the cab so we rolled down the windows and made sure the doors were unlocked in case we had to jump out. We sat there for a minute everything seemed...

Driving down a single lane road at aprox 30-35 MPH, when without any warnings the engine began to make a noise (like it was eating rocks), smoke began billowing out the tail pipes, the dash cluster lit up with error codes (unable to read due to attempting to get vehicle off the road), engine completely stopped, dash cluster would only show the check engine light, when attempting to get the vehicle towed it could not be put in neutral and the parking break had engaged and would not release. Vehicle was towed to nearest dealership and they confirm the engine had "seized" and would need to be replaced. Existing engine has 4190mi. If this had occurred on the highway or busy street I dont feel I could have safely gotten the vehicle out of harms way.

Engine derated when towing travel trailer putting us in an unsafe situation during heavy traffic. No warning other than display on dash reading “reduced acceleration - drive with care”. Took immediately to dealer and they confirmed “thrust bearing failure” manufacturer defect and showed us Field Service Bulletin 25-NA-307 dated 9/30/25.

Pulling a trailer down the freeway and the vehicle went into limp mode. After getting to the closest dealer for inspection, it was determined that the vehicle needed to have the engine replaced

I purchase a brand new 2026 Silverado ZR2 with a 6.2 engine. A little over a week later at 511 miles it left me stranded on the side of the road. Towed it to the dealership and the dealership advised there was a misfire and cylinder number eight. However, they were unable to find a solution and had to contact GM engineers. I had to replace it with another new vehicle and lost money on the “trade”. Dealership only advised that “it needed extensive repairs”. It’s clear that the 6.2 issue had not been addressed properly.
