I have a 2020 Ram 1500 4x4 Big Horn Crew Cab 5.7l V8, which I bought from a Ram dealer last February. It was a one-owner truck. I use it to tow our camper on short trips, otherwise it's our only vehicle.
I am at 53k miles, caught up on air and cabin filter, oil and changes every 5k, and did brake fluid last year. I'm not 100% sure the battery was renewed, but it is marked "May 2023" on the label, so I would guess yes. The truck is "Ram Certified Pre-Owned", which covers engine and transmission to 100k miles, less a $50 deductible Dx fee.
Lately, in the mornings, within the first couple miles, as I approach a stop sign, sometimes I will get a bit of bucking and rough downshifting. This is accompanied by a message "Shift to P to Start", or very similar wording, on the front gauge display. The truck eventually gets to first gear, and proceeds from there normally. This never has happened when the truck is warm, or later in the day.
I have a service appointment next week at my local Ram dealer for an oil change, and will ask them about this. I'll post any updates, but any ideas on how to address this would be appreciated.
