Dean AT4

I have a 2021 AT4 with 9k miles. About a mile from home the truck started bucking. RPMs were jumping up and down from 1k-3k and a loud clicking from the front passenger side of the truck. This all started at 65mph and I had to slow down to 30 to make it home. No warning lights at the time. This morning when I started it RPM's are very low and I still have the loud clicking. I also have "service ESC", "service parking brake" and "service electronic power steering assist". I also have a small amount of fluid on the garage floor(half dollar size from transmission or transfer case area). Love the truck but getting frustrated with the flakey technology in this truck. Update: Dealer just informed me it's an engine rebuild. They have to replace the Lifters and possibly the Cam. Very depressing to spend all the $$$ on a new truck and in the first few months have to have an engine rebuild. 65K for a truck with a rebuilt engine...
