I was driving on the hwy at 70mph when the engine had a catastrophic failure. Several warning lights appeared on the dash, loud metal clunking noises, vibration, and sudden slowing down of vehicle. I immediately pulled to side of road, turned truck off and called local dealership. Upon their inspection, they notified me a lifter bearing failed that would cause engine to seize and would require a new engine.

Hard shifting, shutter, jerk, hesitation feels like the motor is going to fall out. Haven't had the manufacturer look at it, but it's very annoying and embarrassing.

In 2024, I had the transmission replaced due it leaking transmission fluid. The transmission is sealed and there is no way to add fluid. This created an internal problem for the transmission. In January 2025, the engine made a loud pop noise and began performing horribly. My wife and I were on the interstate in a major city and surrounded by traffic. I drove it to the side of the interstate, immediately, and turned it off. I had to call someone to tow me back home(2 hours away) and my wife missed a very important doctor's appointment. Upon inspection, I found failed valve lifters, camshaft, pushrod and valve lifter tray. I managed to get everything replaced and the truck ran fine. March 2025, as I was driving on the highway, the truck stopped running. A message came on the dash screen saying, "Shift to Neutral and restart". I did and nothing happened. I had it towed to a shop. They told me it was a fuse block that was blown and the starter blew so they replaced them. It had struggled to start a couple of times and since I knew it had a new battery, a starter and fuse block made sense. I picked the truck up and in less than 24 hours, it happened again. It stopped running as I was driving and would not restart. The shop has checked GM tech forums and found where someone said to check if the motor would turn over manually. They have tried and failed. They, then, took the oil filter off and found metal shavings in the oil. Their diagnosis is that the engine bearing has seized and is causing the problems. My main issue is safety. My wife and I could have been seriously injured or killed and could have injured or killed someone else when the incident happened on the interstate. The same could've happened with just me in the vehicle or with our children. There were no warning lamps, messages or any symptoms whatsoever before January 2025 for the engine. The truck doesn't even have 100,000 miles on it and I have kept up all of the maintenance.

Transmission shudder and shakes at high speed and low speeds. Getting more noticeable.

- Mableton, GA, USA

My transmission keeps shuttering during passing gear around 50-55 mph. It causes my truck to slow down drastically. It's always a knee jerk. I've serviced my transmission around 40 to 50k miles.

Right after our warranty expired which was 36,000, the transmission started harsh or rough shifting, delayed acceleration, sudden lurching, and shuddering, hesitating to the point that you don-??t think the truck is going to move or someone hit us from behind. It-??s horrible. Every time you drive you pray the truck is going to get you there safely. We tried to take the truck to the Chevrolet dealer and they insisted there was no recall and it was no longer under warranty. Then we took to a private place and had transmission fluid flushed which made it worse. We are waiting patiently for a recall because we can-??t afford a transmission.

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at various speeds, while accelerating from a stationary position, the vehicle shuddered while accelerating. Additionally, while decelerating, the vehicle erroneously lurched forward. The vehicle was taken to the local dealer who reprogrammed the TCM, and changed the oil which temporarily corrected the failure; however, the failure reoccurred. The cause of the failure was not yet determined. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 41,000.

The first thing that happened was the transmission, driveshaft, and rear end all blew at the same time while I was on the freeway. I had to swerve over and get out of the lane I was in and part of the driveshaft was still sitting in the road and cars were hitting it. There was no lights or anything until it happened. I got out of the passenger side of the vehicle and looked under the truck and there was a flame coming out of the rear end. I was able to extinguish it. It was inspected by delta transmission and they said that the rear end gave out first and damaged the rest. Not even 2 weeks later the second thing that happened was my engine gave out. I was driving on the freeway and the engine stalled out on me and I barely got off an exit before the truck stopped moving. I had to get it towed to a shop where they told me that the 2 rods on cylinders 1 and 7 had given out and that I needed a new engine. Again no warning lights or anything until it happened. This all happened in February of 2025.

Lifters froze up on #4 piston twice, both times going down the highway. Transmission would jerk after shifting gears, had bad torque converter shudder from 18 mph on up. Can-??t pull trailer over 55mph without the whole cab vibrating like crazy

I was driving down the interstate stuck in slow moving traffic going 55 in a 70 in Jacksonville, FL. The Chevy suddenly lit up like a dang Christmas tree, parking brake service, check engine light, lane assist, and EVAC all flashing on the screen. Everytime I hit clear it like a new warning popped up. It started to drive super rough as in bumpy, loud and hesitant. I parked it, turned it off. Waited maybe an hour since I went to class, then came back to start it. Issue was still there. I took it to the dealership who seemed more interested in buying it than repairing it, they said it could be a number of things and estimated 10k even though they couldn-??t tell me exactly what was wrong. They knew, they just wouldn-??t say. Anywho, $100 later for a wacky diagnosis, I left to take the truck to an actual mechanic, who stated the lifters failed which caused a bent rod, which then damaged the cam shaft. We had just bought the truck outright for 27k three months prior and only driven it 1,500 miles. It was estimated to be anywhere between 12-15k to fix. Which we didn-??t have that money and personal loans are too high so we traded it in and took a loss of 17k while being thankful that no one was injured driving this thing. The truck didn-??t even have 80,000 miles yet. It was at 75,000 or 76,000. Truck engines shouldn-??t fail that soon or fail at all and this is a common safety issue with this truck. If you have time, google the main issues for this truck and you-??ll see several posts about people complaining about their truck doing the same and having to do a computer deletion to get the engine to function correctly to prevent this issue.

Vehicle is showing the GM "SHIFT TO PARK" error code on the dash board, when turning the engine off.

- Seaford, DE, USA

This truck has very low miles (22,900) and has broken down on me 4 different times over several years. It will randomly slam into 2nd gear and I will almost loose control as the rear wheels will almost lock up. Then the vehicle will barely move even at WOT. This has caused me to almost be in accidents and is very unsafe. GM knows there is several issues with this 8 speed transmission and cannot resolve it. I am afraid to be in an accident because this thing is so unreliable in it's operation. GM needs to be forced to address this issue. There are multiple TSBs on this transmission that claim to be collecting data and investigating the cause of issues dating back to 2020. Time for a repair!

- Edmonds, WA, USA

I noticed up on start up a warning light comes on & display says brake system failure 62 MPH then goes away. I have been reading numerous other reviews online that they are experiencing the same issue. 2nd problem is when I bought the vehicle I noticed numerous oil spots on the tailgate, I asked a GM representative & they said it was road grime, but I noticed the rear pinon is leaking, so it's been leaking since I bought the truck & the dealership either doesn't know it's a known issue or they didn't want to come out & say it.
