2019 GMC YUKON Complaints

I was driving home on the interstate from vacation and I was set on cruise control it was 1 am so not a lot of traffic was on the road thank god. It could have been really terrible if lots of traffic was present as the engine just died without notice! The vehicle was decelerating nothing was working I could not speed up. I was able to get over to the side of the road. I got a notification on my phone that said battery critically low start vehicle to charge battery. Well nothing would start at this point. I lot all power seconds later. I thought that the cruise control was locked up and restarting it would reset it. I called roadside assistance to get a jump and that did not work. I got towed into an auto repair shop. They called me and told me that the engine is locked up that they drained the oil and found metal in it and metal pieces in the oil filter as well. They checked for leaks and said there was none that they could find. They said there was a recall but it was for the exact same symptoms that was diagnosed here but only starting with year 2021. Mine is a 2019 Yukon Denali with low mileage so not sure if all the other Yukons were aged out or already past engine death and that’s why they were not part of this but this should be included in with the open recall considering how everything is the same that is effecting this year that I have and they should pay for a new engine! Clearly the v8 6.2 gmc engines are having major issues I’m just glad I wasn’t going that fast and traffic was slow so I was able to get over safely before catastrophic things happened since there was no warning when this all happened!

I was driving vehicle and came up to a stop sign, once I was clear to go I stepped on the gas heard a clunking sound and the car shut off.

we have had no issues with this vehicle at all. then one day notice a ticking in the area of the valve covers. Sounded to be more on drivers side. Thought maybe just the oil was low which has never happened before. Oil level was fine. I always change oil on regular intervals and there were no check engine lights and engine continued to run fine with no loss of power or ticking changing. It was our only vehicle so we had to continue to drive that day. Wife was driving and said vehicle shuddered and started sounding funny and check engine light came on she was able to drive back home. Now ticking is worse with a clucking rattling sound now coming from oil pan. After some internet searching it very much sounds like issues many others are having with the 6.2l GM engine.

At 70 mph the adaptive cruise control system applied the brakes hard enough to engage the abs system even though my lane of travel was clear. There was a car on the exit ramp to the right applying their brakes not in my path that I believe my vehicle picked up. There were several vehicles behind me and it almost caused an accident. There needs to be a way to disable the adaptive cruse on this vehicle for safety concerns. This has happened to me on multiple occasions and I reported it to the General Motors hotline with absolutely no feedback on the issue.

Complete engine failure. The dealership kept the engine. This happened at a low rate of speed but it would have been much worse if on the highway. Yes the engine was completely replaced. The check engine light came on and their was a loud ticking noise coming from the engine.
