My 2019 does this as well. Not a deal breaker but very annoying when backing out and my wife said, “this is what a 50k+ truck sounds like?” She’s not wrong, I don’t like it either.
I had told my dealer about the moan when I got my replacement floor mat but we couldn’t recreate it together on a drive.
Found this postsent him an email with TSB and he emailed back this morning to schedule the fix no questions asked. I get new pads out of it, which are not expensive but prolongs the need to replace in the future so why not get it.
Glad I am developing a relationship with my shop manager, makes life much easier when something is needed. I’ll report back after fix next week.
I do write a review each time he has helped me and that actually seems to go a long way in his willingness to help, or at least I think so. Reviews are huge to dealerships/service departments.
