On our way home from vacation our engine failed and stranded us. This is the second engine that has failed and the vehicle only has 30220

I would like to document it took 7 trips to set the monitors after a failed smog check. That is 21 time going from 55 miles a hour to coasting to 20 miles a hour. on a freeway. Three times per trip at 2:00 - 3:00 in the morning. Also my Catalytic Converter went out at 26,000 miles. It should last 70,000 - 100,000 miles or 10 years. Catalytic Convertor was replaced by dealer. Will i have to replace it every 26,000 miles?

From the time i got my 2024 yukon denali i have had problems with the electrical systems not working, it was in the shop for 2 months upon delivery to me when it was brand new, and since then i have had issues with the engine racing, the start button not working, or cutting off and on , on its own, recently the motor cuts on but never turns over. It has been in the shop again for over a week now and they replaced the engine control module and it is still doing the same thing. The dealership is now telling me its a wiring issue causing it. It has been something the entire time I have owned it. I paid 90k for a vehicle that has major issues. I am looking into the Lemon law in my state of NC, and filing a complaint with GMC to see if I can get a replacement vehicle or traded.

Vehicle shut-off while driving on the expressway, around 70-75mph. Upon vehicle turning off, I had no option but to "coast" off to the left side, which thankfully, freed me from traffic for the most part. If anyone who have been a foot over, they would've hit me. I have had numerous electrical issues with this vehicle and have taken it to the dealership but they have been "unable" to duplicate the issue. Vehicle was immediately taken to the dealership (and they still have as of this incident report submission). They told me last night that they will keep it again today and test drive it again to see if they can get it to do anything but if it doesn't show anything new, they have nothing to diagnose and will give me my car back. After requesting a copy of repair orders and a list of the history codes in my car, I am beside myself that anyone thinks giving me this vehicle back to drive is ok. See the history code report in documents uploaded. These are MAJOR safety failures in a large vehicle.

We were driving on the highway when the service lights came on along with the check engine light started flashing. The truck sounded like it hesitated a little, but the lights turned off and it drove his normal. We exited the freeway as we were close to home came home, parked it turned it off and turned it back on to test it, and it hesitated to turn on so we took it straight to the dealership where they repeated the issue. We left it there. They did not call me so I went up to the dealership the following day to check on this and I had not heard from them they told me why they were on the test drive that the engine had locked up. My vehicle was a part of the initial recall. They told me that it passed the inspection and they changed the oil to the new oil that was required and now at 12,000 miles my engine has failed
