Vehicle engine began to stall and make clanking noises. The engine light came on. Was able to get to repair shop, which was very close. Repair shop was able to verify that problem was due to an engine "cylinder clapse". Four cylinders where repaired on side of the engine. They indicated that because of issues the GM 5.3L V8 engines have been having (possibly ceasing and causing accident and/or injury) the other four cylinders could possibly cause the same engine problem in the future.

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.

Driving on [XXX] going 75mph near Columbus Ohio and saw white smoke coming out of the back end of my truck, then looked at dash and low oil pressure light and shut engine off warning lights were on. The engine was knocking and barely able to keep idling. I pulled to the berm then looked for nearest service station I could get to. I got off highway at next exit and put 4 quarts of oil in and drove to dealership just across the street and had mechanic look at truck. Upon inspection the mechanic determined that the oil coolant line had detached and there was no crimp on the hose. The engine had catastrophic failure. It is currently at dealership and they are ordering and installing new engine at a cost of $10,100 to us. This problem is a known defect to GM as it was first reported in January 2020. There was a recall in Alaska and Canada but not to the lower 48 states. The recall and numerous consumer complaints state that the hose crimp fails allowing the hose to separate and leak all engine oil which will cause engine damage. I come from a loyal GM family and have driven GM trucks and cars for 30 plus years but question the integrity and reliability of the brand now. I-??ve seen complaints for this issue across the board of all different mileages. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While traveling on the highway, engine started smoking and received warning of low oil pressure and to turn off the engine immediately. After mechanics investigated it was found that the oil cooling line had become uncrimped and fully detached resulting in low oil pressure and oil spraying out/ full draining. After researching this problem I found a NHTSA bulletin of a GM customer satisfaction program N212326940 where GM identified other VINs of the exact same year make and model having this issue. My vin was not included in this program and it is clear that GM underrepresented the number of vehicles that were affected. I was traveling at approximately 55mph at the time and this could have caused a serious accident due to GMs failure to identify all vehicles with this issue.

A few months ago the main oil cooling hose broke while I was on the freeway at 65 mph. I lost power to the vehicle and prompted to shift to neutral and to shut vehicle off. I did, after exiting the vehicle, I noticed all engine oil had been exited from motor. I thought the worst, new motor... Dwayne Lanes in Arlington had told me everything was fine, the had inspected the pan and looked to be no damage. Fast forward to last week, same issue repeats, minus the oil. Lost power on a 2 laned back road, extremely nerve racking! Now the dealership says I have metal debris in my oil, and a replacement is required. This is referenced as uncommon, but how could that be if there is a national shortage on the DFM/6.2L L87 V8. Purchased this vehicle with 18,000 miles, 2021. 2025 has 56,000 miles. I drive less than 9,000 per year. GM knows there is an issues, this is extremely dangerous and costly for the consumer. Hope DOGE looks in to this

The contact owns a 2019 Chevrolet Silverado 1500. The contact stated that while driving at approximately 45-50 MPH, the vehicle suddenly lost motive power and decelerated to 20-25 MPH. There was an abnormal ticking sound coming from the vehicle. The contact stated that the check engine, traction control, and service parking brake warning lights were illuminated. The message -??Service ESC-?? was displayed. The driver was able to pull over safely. The vehicle was towed to the local dealer, who determined that the failure was due to the lifters. The vehicle was towed to another local dealer, Cadillac of Jackson (700 Adcock St, Ridgeland, MS 39157), where it was diagnosed and determined that the lifters had failed in cylinder #4, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was contacted and opened a case. The approximate failure mileage was 114,000.

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.

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.
