Just took our 2021 JLUR to the dealer today for the same thing. We smelled burnt rubber and didn't know why and this was the cause. I don't understand how this could happen. We still have the stock wheels/tires.
The same thing happened to my 2018 JLU Sport and I thought the noise was from the new steering box because it happened just after the TSB was done. They couldn’t identify the noise. Now that I’m out of warranty we’ll see if they will still replace the fender liners since it clearly happened when it was still under warranty.Mine is at the dealer today getting new fender liners installed. Mine is a 2021 eco Rubicon. We hit high winds on our way to Moab a month ago and both fender liners where eaten up by the front tires. My dealer was like no problem we will handle it. I checked the fender liners in a gladiator and a 392 that where on the showroom floor and they where a much thicker heavier material than the ones that where on my jeep. Hopefully they've updated the part.
Well that's good news. Yes, I70 is a beast. It seems it has eaten numerous jlu fender liners. I'm heading back down the I70 to Lake Tahoe, we will see if the new liners hold up!The service department called this morning and said they are going to replace ours. I’m glad I don’t have to replace them myself but hope they can make an improvement on the original configuration as we’re heading back to Colorado in 3 weeks. Interstate 70 is a beast!
I70 in Kansas got my left front liner a couple of weeks ago. Temps were above 100 and had high winds gusting from the right. Heard a sound similar to hitting a rumble strip. When I pulled over I found a large section of the liner almost torn completely off. I talked to the service manager at the dealership today and he's ordering a new liner under warranty.Well that's good news. Yes, I70 is a beast. It seems it has eaten numerous jlu fender liners.

Update to my post above. I recently installed a new pair of American Adventure Lab fender liners and took them on a wheeling trip. They installed very easily and I've had no issues at all with them. Bonus...they look great and were specifically designed for the diesel so they're is no washer fluid bottle interference. Thanks to the folks on this forum for pointing me in the right direction!Have the same issue with factory fender liners. Both sides got ripped up by my factory tires driving down the highway. Jeep needs to recall this part. I've been through 2 sets of factory paper thin fender liners on my JL Diesel. Got tired of dealing with it and spent $550 on a pair of Poison Spyder front fender liners but they have been a fail as well. The drivers side front tore at the 90 degree bend where it mounts to the frame. (Picture insert) Not sure why PS thought they could span a gap between fender and frame with 16 gauge aluminum and have it last. Mine broke after 4 weeks and zero off road trips. The passenger side lower rear does not fit because a fluid bottle is in the way. Had to zip tie it in to get it to stay in place. Please, FCA, recall this poorly engineered fender liner and stop forcing people to the after market.
