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.

The valves, pistons, head gaskets are all affected and malfunctioned. They caused burning of the oil and loss of coolant. I took it to the sister dealership of where I purchased it to track the leak and they stated that it was fixed. Upon picking it up and driving it to my home and then right back to the dealership (apprx 12 miles) the truck was making big enought plumes to where it was making other operators pull over or cough. I was following behind the truck to video record and it was producing so much I could not see and had to close my vents to not cough. Our oil said 65 % but decided to check it and there was barely any oil present. Had it towed to the dealership and after picking it up it was only worse than before. This is a safety issue. An emissions issue also. Thank you.

While driving on the highway with my four year old with me the truck jerked and then triggered 3 lights on my dashboard, this made getting to a safe spot uneasy as it was jerking and sounded like it was reving up and down and overall sounded not good. Truck was towed to mechanic and was discovered the lifter failed due to the Active Fuel Management (AFM) or Dynamic Fuel Management (DFM) in that engine model. That failure caused further engine damage to the cam shaft and needs an entire rebuild of the top part of the engine. There were no other indicators that this would happen until it did. I contacted Chevy and they are aware of the situation and offered "cost assistance" only if it was brought to a GM dealership. Given the engine had to be taken apart to figure out what was wrong they said the only way to get assistance was to have the garage put it back together and then tow it there and have their mechanics look at it to determine if they could cover part of it. This isn't a viable option to me seeing how there isn't a guarantee of any assistance and would potentially cost more long term.

My complaint is regarding faulty oil lines that are known to be defective by GM/Chevy. The oil lines begin to leak in colder weather and according to discussion boards, have even been known to come off completely while at speed and purging all of the oil from the vehicle. This can result in the almost immediate seizure of the engine and loss of control of the vehicle. ? GM/Chevy acknowledges there is a problem with these oil lines by their creation of a Customer Satisfaction Hotline around 2021 instead of doing a full recall. My 2019 chevy silverado 1500 is experiencing the exact same issues with the oil lines as stated by hundreds of other customers. I have contacted both GM and my local dealership and have been turned away advising my 2019 Silverado was not part of the right "build number" associated with the special coverage that they voluntarily created to avoid the full recall of all 2019 and possibly more model years with defective and dangerous oil lines. As reported previously, the oil lines are likely to begin to fail in colder weather which could make for more dangerous conditions should they fail completely and come off of the engine. Although GM states my vehicle is not part of the conditional coverage, my lines began to fail a few weeks ago as my temps dropped well below freezing.
