Morning,

I wanted to reach out and see if anyone had experienced similar symptoms. I searched and found nothing similar to my situation.

Just bought a 15 day old 2021 TRDOR 4x4. It currently has 374 miles but I have noticed this since I purchased it at 56 miles.

At cold idle, the engine vibrates the truck noticeably for ~3 seconds and then it goes away for ~3 seconds. This continues to repeat. I haven't idled the truck long enough to see how long it takes to disappear, but it does not do this when the engine is warmed up to operating temperature. It only does this in Park or Neutral, not in Drive.

I still have my 2016 TRDOR 4x4 and it does not and has never done this. I've driven many other third gens at cold idle and have not noticed this on any of them either.

I may be making a mountain out of a molehill but due to the intended use of the vehicle (overland rental) I don't want to ignore it and have something bite me in the butt later.

Thanks for your help.
