We bought 2 of the same exact trucks last year. They each had no miles on them. My business partner was coming home from vacation and stated hearing ticking. We took it to our mechanic and he said it’s a blown motor. Prior to leaving for vacation, an oil change was done on the truck. When the mechanic said the motor is blown he also said it’s down 3 quarts of oil. All scheduled maintenance was done on the truck routinely. We took the truck back to the shop that did the oil change and they had recorded the service, there was no doubt the oil was changed the prior week but it was now black and down three quarts.

I have a 2023 Chevy Silverado 1500 3.0L Duramax Trail Boss. Temperature gauge keeps flocculating, engine fan kicks on at 100% and shuts off the AC. Warning on dash engine temperature to high AC shutting off and engine over heat. Took it to the dealership for the truck is still under warranty. They diagnosed it as a faulty coolant control valve. Was told it was safe to drive by the technician but I question that. Dealership ordered the part four weeks ago and it still has not come in. When I inquired about the delay, I found out it is on back order and the availability of the part long wait time. Further research found that this is a systemic issue owners are having with this specific engine since 2020. Yet GM has not done a recall nor is there supply stockage of this part, seeing how this part commonly fails.

While driving 55 mph and towing my boat on a 2 lane paved road , I started up a slight incline and the transmission downshifted so hard that the rear wheels locked up long enough to throw us into the dash even with seat belts on. I turned around an drove back home with it locking up again. No codes or lights on the dash. Took it to dealer June 26,2025 for dealer to diagnose issue. They kept it overnight and drove it about 60 miles, called me the next day to pick it up saying they could not duplicate the rear wheel lockup and since there were no codes there was nothing to fix. Tried to tell me it was my boat trailer causing the issue. Boat trailer has surge brakes, nothing electrical on trailer brakes. Over the next couple days the rear wheels locked up 2 more times. Always as I started up an incline going around 50-55 mph. No lights or codes July 2, 2025 we recorded on video 2 rear wheel lockups with the second lockup starting a slight fishtail on dry pavement and leaving a 5 foot skid mark. Went back to the dealership with the video and they said again if there are no codes they can’t fix it and they would try to duplicate the issue for me to leave the truck and not give me a rental vehicle , and no timeline on how long they would try to duplicate the issue. I did not leave my truck there and they kept promising to call me when they had a loaner vehicle for me to use. On July 14, 2025 ,while still waiting for a loaner vehicle the transmission finally locked up the rear wheels and check engine light came on. My mileage was 43078, it took 1,193 miles to finally throw codes that the dealership would fix. Codes were P0700 and P0747. These are same codes for safety recalls N242454440 and N242454441. Obviously my vin is not included in the recalls but the dealership should have put the software on my truck the first time I was there on June 27th, the same day they completed the Pa.state inspection on my vehicle. I wouldn’t have had to experience this unsafe conditions.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001).  GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274.  This presents a potential safety risk that warrants further investigation.  ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.
