2017 Gen3 - in4 repair...

Yo!

So my taco is in the ER (Dealership). They have 3 master techs looking at it and are currently stumped. Here's what happened:

It's cold here in the midwest and was around 4*F and I got to work and parked my truck as I normally do.

I was leaving for the day and pulled out from the parking spot and started hearing loud clicks, like something is in your tire or like someone put a baseball card in your bike spokes. I stopped and performed a quick visual but didn't see anything. As i pulled onto the road once it hit 25mph it got bumpy.. pulled over again and gave another visual and figured it was ice or my P brake hadn't fully disengaged. I decided to drive a bit more and attributed it to a cold truck.

Once I hit 50 MPH i could tell something was definitely wrong. My speedometer said 55 but i could tell i wasn't going that fast and the whole truck was bumpy. I slowed it down, got home and called the dealership. For the most part, it's a stock truck (grill, 12v autostart and a tonneau cover) and the dealership has been the only one to service it.

I've got a '19 loaner now while they keep poking at it trying to figure it out. I'm super bummed cause i love this truck and hoped to keep it a long time. On they way home from the dealership i stopped for tacos.. figured it was the right thing to do. i'll let ya know what they find.

(note: i do use 4wd but only when necessary (heavy snow, ice)and i don't off-road. i was in 2wd when leaving my lot yesterday)

 

Possible belt separation on one tire, aka tire bulge. Just throwing it out there, as a cause of your problem.
