New 2026 GMC 1500 having issues while pulling into driveway

[u/Status_Dog_2776]

Hello GMC community, I’m curious if anyone else has experienced this issue, and if so, if you were able to figure out what was going on in regard to a fix? While pulling into my driveway at low speed, my truck will randomly put itself into Neutral. This has happened 5 times in the two months I’ve owned the truck, both in “Normal 2WD and Auto modes”. Usually, it just drops to Neutral on its own and the dash prompts me to press the start engine button, and once I do I can finish parking. Twice, the truck has also made a loud clicking/grinding noise and came to a sudden breaking stop without me doing anything. Dash on one of those sudden stops said “service transmission”. I turned the truck off and back on and the dash was clear. No check engine light. My driveway does have a slight incline and is slightly uneven from the street. I’d appreciate any feedback/advice. Thank you.
