The vehicle will not allow the truck to be turned off everytime, it states the truck must be in park to be turned off, and the truck is in park. The engine lost power and staleld twice, and loses accelerator power multiple times. The transmission has dis-engaged 3 times. All of this since July 2026. The truck has 54,000 miles on it.
The motor blew——It is confirmed by a Chevrolet Dealership and they are now getting a reman engine as a replacement—There was a loud noise then it went dead—-Was able to start it and there was this gawd awful noise coming from the motor—Had it towed to the dealership where we were just told it was a motor failure
My 2022 Chevrolet Silverado 2500HD High Country 6.6L Duramax engine has an exhaust leak that causes diesel exhaust to travel into the pickup's cab through the outside air vent and air conditioning system during the exhaust system's regeneration. This occurs when the regeneration occurs in city driving especially at low speeds, stop lights, stop signs, parking lots, etc. The pickup has been to the dealer to find and make necessary repairs twice and is currently at the dealer's shop for the third time. This issue with the 6.6L Duramax pickups appears to be a common theme amongst owners and GM should be providing dealers with the appropriate fix with a recall of the exhaust system. This is a safety hazard as carbon monoxide enters the cab with the diesel exhaust and must be rectified. On my pickup, this started at approximately 55,000 miles. Thank you for your prompt attention to this serious air quality issue inside the pickups' cabs.
See attached document for complaint.
While driving on the freeway in a construction zone, I smelled a burning oil smell. I considered the possibility it was in relation to road repairs being done (roads being repaved, ie tar resurfacing). I was cut off by another vehicle and depressed my brakes and I saw a poof of smoke over the front passenger area near tire. I noticed all of my gauges were in the normal ranges (temperature, battery voltage, etc.) In less than a minute my truck went into limp mode and advised it had a DEF system issue and it would be limited to a set MPH and a set number of miles. Check engine light came on and another driver alerted me that the underneath of my vehicle was on fire. I pulled over to the side of the highway and my truck became engulfed in flames in. Truck is under factory warranty, unmodified, never been in an accident and has had all recommended services performed at local dealership. There was a significant amount of traffic and luckily I did not collide with anyone or set neighboring dry grass field on fire. Fire department responded and extinguished the fire, but it is a total loss. Insurance company has been notified, and vehicle will be available for inspection by appropriate agencies. While local law enforcement did respond, they did not take a report because I didn't hit anything, and the only property damage was my own. (There is documentation of the event, but just dispatch notes.) Prior to the situation above the truck had been at operating temperature for at least 20 minutes and I had traveled for about 20 miles on the highway. The total distance traveled from when I smelled the burning smell was maybe 1.5 miles.
I started to her a light tapping in engine and also noticed smoke color coming from exhaust when I used the remote start and at other time. Truck has been going through a quart of oil or more at roughly 3400 miles before the 5000 miles before the service is actually due. Spoke to dealership several times and they say that is normal. Called GM directly and filed a complaint.Never had a vehicle that needed oil before service was due. That’s not normal. I feel like I’m getting the run around
I was almost run over by a Semi-Truck when entering the freeway because my 2022 Chevrolet Truck would not accelerate. I was told at the dealer the loss of power was intentionally caused by the onboard computer. It is programed by the manufacturer to do this anytime certain repairs may be needed. In my case, the life-threatening event I experienced took place because a sensor went out and the computer thought a repair was needed.
