‘19 Sierra Denali Rear seat Clicking/Knocking

[TomCorey]

Anybody experiencing a clicking or knocking sound coming from the rear seat area in a 2019 Sierra?  It happens intermittently but it’s so annoying. I don’t think it’s the headrests like some have experienced. Also anyone experiencing a clunking sound coming from why seems like the rear suspension or leaf springs. Going around sharp curves or bumps at low speeds

My 2019 had two noises coming from the back seat area. One was the headrest post rattle. The other was the plastic “chain” that houses the wires coming immediately off of the sliding window. It rattles against another piece of plastic right next to it. The solution posted my another forum member was to place some Velcro (soft side) between them. It worked for me. There’s a thread somewhere here that has pics and more details.

 

Not sure if that’s what you’re hearing, but might be worth a shot.

Thanks. I did mess around with 2 wires that lead to the sliding windows because I suspected it might be coming from that area. Every time I mess with them the sound goes away but then comes back. Are you talking about the plastic chain to the left of the sliding windows?  I don’t know why that would be making a clicking noise but I think I know what you are talking about with putting a piece of soft Velcro between the chain and plastic housing
