The backrest adjust switch on my passenger seat is broken, and I have no idea how. The plastic paddle is completely broken and detached from the switch inside the seat. I guess someone snagged something on it and didn't notice? Maybe me? No idea, but I guess it's a fragile little doohickey. That said, my Tesla store put an order in for the part, and is going to send a mobile unit to my home to repair it once the part comes in. Can't ask for much more than that.
