This just happened to me last weekend on the interstate around 80 mph in Custom Mode (Sport settings). I have around 4K miles on my 2026 level 1. The first time it happened it caught me by surprise, so I had to try and replicate it to make sure I was not imagining it. I could replicate it about half the time at around 80 mph with a light acceleration. I have seen it described as a "trailer-tugging" bump or shutter, which is what mine felt like. My wife could even feel it in the passenger seat and asked me what was going on.

I think this is all related to the shitty driveshaft.

lol yeah… I’m about a year into ownership and so far seems to be harmless. Just annoying.

This has happened to me one time only on the highway at roughly 70-75mph. Truck had about 1500 miles on it.

I think it’s probably that 91 octane you all have to use west of the Mississippi. Lol.

Oh crap I think I might’ve just jinxed myself.

I feel like I’ve experienced this same thing. It was 4am on the way to the airport for a 10 day vacation in which I’m now on. So… no thorough testing. But OP’s description is as close to what I experienced as I can find. I also run custom mode with the same settings. I don’t like the HUD info in sport mode.

It happened four times on the 30 minute drive. It kinda felt like it was related to shifting around 80 mph but couldn’t really focus on testing.

So disheartening to me as I love this truck. Like so much.

Kind of off topic here but I hated the hud in Sport too. I figured out how to change it where I can see the speed etc. Use the toggle button on the left side of the steering wheel. Push it up or down until you get to #11. The. You’ll see the hud settings and you can customize them how you want it.
