My 2019 6.2 engine suffered from severe loss of compression caused by internal piston ring failure and bore scoring also loss of power . In the 6.2L engine , piston ring failure and ring- seal are direct consequences of connectiing rod alignment errors, My engine failure is proof that this is the same situation that is currently under investigation and have proof with compression test and report done by my Technician . First time it happened to me it just stopped on me in the middle not the road all lights came on the dash including ESC light something it never done before. But before this happened it had been running rough. I took it first to the local repair shop and they wouldn't be able to work on it , So I took it to the local dealer and there it got. worse from there . Took it to the dealer changed the battery and it was running again but they found it had really bad leak on the rear main seal spent over $3,000 for all of it. Thought the problem was over after that months later after it was running rough again took back to the dealer and from there they told me there were oil coming through the piston rings and metal shaving in the engine and from there found out engine needed to be replaced Warranty company would not cover it. I had to pay 1500.00 for rental car coverage, teardown of engine was 3,500 since the extended warranty did not cover it Endurance Warranty Co. denied my claim.Dealership is charging me out of pocket charges of 13,495 for the engine replacement plus engine teardown Endurance Warranty Co. denied my claim. Even after paying for warranty for almost 2 Years. GM says manufacture warranty is out of coverage can not be apart of the recall but engine failure mirrors 21-24 recall 6.2 engines.

I was experiencing rough gear shifting jumps and low power/acceleration but it was spotty and not continuous. While I was traveling on cruise control, my truck started misfiring. Once I got home the whole truck was shaking in place. I popped the hood and noticed the engine itself was shaking on the motor mounts. On the way to the mechanic, several lights (including check engine light) came on (the codes thrown were P0300-P0308). The mechanic attempted to clean the fuel injectors (that were replaced 30k miles go due to failure as well), but that did not solve the misfire. I was told the cylinder was dead, and upon inspection of the oil filter there were metal shavings throughout it and the engine, as well as a bent cam shaft. All symptoms and issues I've experience, which resulted in a complete engine swap, are similar to those of the 2021-2024 GMC Sierra 6.2L engines that were just recalled. I would like to know how many other 2019-2020 5.3L engines have had failure before 90k due to similar issues and if there is a larger concern here.

Complete engine failure. Absolutely insane. All lights on dash, engine seized while driving!!!!!!!!!!!!!! Unbelievable that GMC keeps making us fix issues and pay for it! They won't cover the cost. This has been happening too much and putting my family at risk!

Last Weekend was taking the kids and my brother and his son fishing, so 2 adults in front seats 3 kids on the backseat. Got my boat all hooked up and we're off. About 2 miles down the road the truck rebs up really high and then bottoms down hard on the RPM's. As soon as this happens all lights and instrument cluster goes crazy. Check Engine light on, Parking Brake Light On,Traction Control Light On, And I'm sure I'm forgetting more. The Cluster states ESC failure drive with caution, Do Not Exceed 43 miles per hour speed limit Brake Failure and So on. I have since found pictures pf the exact same thing that happened to me that morning and will provide. Needless to say I have no brakes and have a 19 ft bass boat behind me. All I could do was let off gas completely and push brake pedal all the way to the floor and pray that it stopped. Good Lord willing it did. Pulled over asap and killed truck, let sit a few minutes while I assessed the situation and cranked it back up. All lights and brakes were fine. Has not done it since but I only drove to dealership to find out the issue and 4 days later still no answer. Its a 2019 with only 26000 miles, and has never had 1 issue before this

After having a recall issue fixed on the ABS braking system of my truck, I remoted started it from gm's onstar app, which caused the dashboard to light up like a christmas tree and give a number of errors, including a solid engine light. Gm onstar diagnosis identified that there is now another issue in the ABS braking system. There has been no mechanical failure at this point, but I am concerned their maybe as others with this same issue have seen mechanical failure.

I had no issues with my truck until I went and had the most recent recall done for the brakes. I since have had brake issues twice. Once, hours after having the recall done I got in my truck and started it and all the dashboard lights were illuminated and I had to push the brake pedal to the floor after accelerating. The other instance was a week later after remote starting my truck from the phone application had the same scenario play out.
