Model 3 and Y Seat Belt Adjuster Rattle Fix

Last Updated on September 9, 2020.

From what we’ve seen on the forums and video comments, a lot of Model 3’s and now Model Y’s have a minor rattle coming from the seat belt adjuster area on the driver’s side. It typically only happens when the seat belt is in the bottom position and you’re on a rougher road, but it is an annoying buzz right in the driver’s ear.

After Tesla failed to fix it on our Model 3, I made several attempts with felt tape in various places, but I’m happy to report I’ve finally resolved it for good. The fix is pretty easy and only takes a few minutes.

Materials Needed

  • A few inches of this felt tape in just the right places did the trick.

Suggested Tools

  • Plastic trim tools help remove the cover.
  • Sharp scissors to cut the felt tape.
  • A clamp to hold the seatbelt while you work.
