Driving on a farm to market road, I passed a slow dump truck, when I let off the gas, every light on my dash came on, I lost all power and my engine started knocking. I Had 60662 miles on it. I bought it with 442 miles on it. The rod bearing went out and threw the rod thru the block. Complete engine replacement. The issue is not only on the 6.2 motors, I know many 5.3 ecotec owners that have had this issue as well as me. gm file # 9-13551227044.

I own a 2023 Chevrolet Silverado 1500 with a 6.2 liter L87 engine that is currently part of class action lawsuits. While driving down the highway with a car full of passengers at around 75-80mph, the vehicle shut down and would not accelerate. Frantically from the left lane, I crossed traffic almost causing an accident multiple times, to the shoulder of the highway. I then called for a tow truck to tow the vehicle as it would not start. The vehicle was towed three hours later, to the dealer (Quirk Chevrolet) and I walked off of the highway with the group of people. We then ubered home. The dealer diagnosed some mechanical issues that they said were the issue and -??repaired-?? the vehicle. I picked the vehicle up three days later. Three weeks after that I was driving down the highway at about the same speed, 75-80mph, and my vehicle shut off again and was unresponsive. I had to then cut across three lanes of traffic frantically again and I coasted off of the highway due to an off ramp being right there and me acting quickly. The vehicle was unable to start for about 20 minutes and when I finally got it started it was making a loud audible knocking noise. I shut it down and called for a tow truck to the same dealer I had it serviced at a few week prior. I got a call the following day stating my vehicle needed an engine replacement and that I was most likely going to have to wait four months or more for it. They stated that they did not have any loaner vehicles available for me due to four other 6.2L engines needing replacement and if they had any available in the coming months, they would all be midsize SUVs. They stated that there was nothing they could due to get me a truck and only a midsize was offered which would not be any time soon anyways. I called three other Chevy dealers in the area and they stated that they all had between 3-5 seized 6.2L engines in the shop. There were no warning signs prior to this happening minus the repairs stated above and maybe a tic

While driving down the interstate on cruise control with my son, my truck dash board lit up with no warning, service esc, service parking brake, check engine light flashing. The cruise control was disengaged and did not function. The truck began to run very rough.small amounts of White smoke where visible from the tail pipe. Acceleration was very hesitant. The codes were scanned and showed misfire on cylinder 1 and a rough idle code. The repair shop confirmed I had two failed lifters that destroyed my camshaft and send metal throughout my engine. The repair was to replace the entire engine.

I was getting on the freeway and all of a sudden a lost power and heard a loud clunking noise. I drove as fast as I could to get in a safe area. Afterwards I had my vehicle towed to my mechanic. They said engine failure and possibly transmission failure. They found metal shavings in the oil. I had changed it myself a few weeks prior. I then took it to a gm dealer. I was just outside my powertrain warranty at about 70k miles. They said the same thing. 24k to repair. I had to junk the vehicle.

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.
