I can't find it now, but I remember seeing a thread where the front passenger seat is able to be folded all the way forward with the headrest removed. Is perhaps that only possible in the older versions (or software version)? I have a 2021 Model 3 (delivered end of 2020). Or am I missing some setting or trick to override the default stop limits?
Maybe they updated the software so the seat can't fold all the way forward (I remember seeing a thread where someone broke the mirror in the visor by putting it all the way forward with the seat all the way up). Anyways, in my 2021 the seat can only fold forward such that the seatback is roughly vertical (with headrest on and seats all the way up, it would be pushing on the visor or the front crossbeam). With headrest off, there is plenty of room available to fold further forward (as I can in my old car with fully manual seats).
Folding back also has a stop limit. Even with the rear seats up, the seat doesn't fold all the way back (stops roughly in the position where the back of the front seat would be touching the rear headrest when rear seat is folded). I thought removing the rear seat cushion would help, but given the seat stops before that becomes a factor, it actually doesn't help at all.
Anyways it seems the only way to put long cargo (folding only passenger side rear seat down) is to fold passenger seat backwards (and remove headrest so it doesn't get in the way). I was able to transport two 8ft 4x4 posts (with room to spare in front) this way. I suppose for longer cargo than that (like 10ft lumber) folding down the driver side's rear seat would work (so the lumber can go diagonal).
