Twice the shift to park function of the vehicle has failed, once in 2020 and again in 2025, it appear that there is a recall for the year make and model vehicle, but for some reason my particular VIN in not included in this recall. The recall needs to be expanded to address this safety issue.

I purchased my new GMC Yukon XL in October 2024. In February, with about 9,000 miles on it, I was approaching a highway intersection and beginning to brake. My vehicle put itself into Neutral, and then shut off -- while I was still moving. No dash lights came on, except for a message stating that I needed to press the brake and restart my vehicle. I took my vehicle into the dealership where I purchased it and they kept it for 8 days. They were unable to reproduce the issue and didn't do anything to mitigate the problem except for doing a "radio update" and adding lubricant to a window track. I was told I have to wait until it happens again and try to record it.

On Jan. 19, 2025, while driving home, I started hearing a loud knocking noise from my engine. Lucky I was still on residential streets so I was able to safely pull over to a parking lot. I was planning to drive the 40 miles home on the freeway when my wife said it might not be safe. That was when I decided to drive to my sister's house. Only when I pulled into the drive way the check engine light finally came on. The next day, I had the vehicle towed to the dealership and they diagnosed that I needed a new engine. They did not go into specifics as to why I will need a whole new engine but they did tell me that this was common and that they had other vehicles waiting for an engine also. My vehicle has been sitting there since.

While driving down the highway, the engine completely locked up upon diagnosis at the dealership we were informed that repairs could take 4 to 8 months

I was driving down the highway at 75 miles per hour and my engine shifted from drive to Neutral on its own, luckily I was able to get off to the side of the road as it would not shift back into drive. I got off the highway and was able to put it in park but it would not shift into any other gear. I turned the vehicle off and it would not power back on. It was completely dead. I had to have it towed and drug up onto truck and back off the truck as it was not shift into Neutral. It has now been at the GM dealership for 16 days. The engine had seized they said and needs a new one. this is a 2023 and only has slightly over 20K miles on it. They have told me there is a national shortage on engines and I am in line to get one but there is no telling on how long that will be. I am out of a car for 2 weeks and who knows how much longer. GM has given me a rental car but a very small SUV that does not fit my family. I have no idea how long it will be nor do they until I get a new engine in my vehicle. I was fortunate I was able to get to the side of the highway and stop safely.
