2026 Tesla Model Y rear seat rattle fix

Описание: This metallic rattle on a 2026 Tesla Model Y seemed to be coming from the rear seat base or the hinge on the left rear seat, but after countless hours diagnosing, test driving, and taking out the rear seat base and seat back panels, the rattle was identified to be a bolt rattling on the center seat belt tensioner "box" which is attached to the metal frame of the rear left 60% seat.

Slight vibrations from driving travel up the metal rear seat base frame, up the metal seat back frame, and the bolt would rattle against the metal and plastic housing of the seat belt tensioner. I ensured the bolt was torqued to Tesla service manual specifications, and it still rattled to a lesser degree so I stuck on 2 felt pads (which you stick to the bottom of chair legs) to create pressure against the bolt from the seat back panel, and this stopped the rattling.

I also applied felt tape to essentially all metal components of the rear seat base frame and seat back frame in case any rattles were being caused by contact to metal and while this may help slightly reduce vibrations, it isn't the root cause. The bolt is the root cause.

Let me know if you have any questions on the steps I took or the process to find and stop the rattle.
