Engine has developed a serious lifter / cam issue. dealer identified it as a result of Displacement on Demand design. Total engine replacement recommended by dealer but since the mileage on that vehicle is over 100,000 warranty, the repair is not covered. Known issue, should have been pointed out by dealer / manufacturer before warranty expiration. FYI _ I do all repair work at dealer. Vehicle looses power intermittently is is not drivable at any distance. Manufacturing / design issue known over different versions of this engine since 2010, I believe.

Having the same issue as the recent recall on the 6.2L v8 engine failures. This has been an ongoing issue from well before the 2021 and up manufacturing dates according to many online complaints. My vehicle now needs a motor due to complete failure.This came out of nowhere with no warning very recently. It is not drivable and a new motor is not in my budget when I still owe money on the truck. GM needs to step up for the rest of these failures.

Experienced error code of P0307 after vehicle backfired while on highway. Check engine light and stabilitrak lights immediately turned on and vehicle was shaking violently. Immediately took vehicle to an independent shop to have it looked at. After running diagnostics, pressure tests, and bore scope. It has been determined that piston in cylinder 7 is a complete loss and has a 0 pressure reading. From talking with shop owner he said he sees this issue quite often with GM vehicles due to DOD or AFM (active fuel management) that GM has on their engines. I'm at just shy of 67k miles, out of warranty, and needing to replace the engine.

I was waiting on the oncoming traffic so I could make a left turn. I had plenty of time to make my left turn in front of oncoming traffic, as I proceeded to make my turn all if a sudden my steering wheel locked up, stability trac light came on, my power locks locked and unlocked intermittently and truck engine died. I had to restart engine and it did it again as I was moving attempting to finish my turn. This happens on a regular basis now anytime I have to turn steering wheel it locks up and does this. Sometimes it does everything I stated above but engine doesn't die. This is dangerous. A couple times when it does this my truck doesn't have any power to start but wait 30 seconds to a minute, power will restore and you can then start it up. It almost sounds exactly what is happening that the 2015 gmc 1500 are being recalled. This happens now on a daily basis.
