2020 Toyota Sienna Body & Structure Problems

Your driver's side power sliding door became stuck and wouldn't open, even after disabling the power door system. The cable for the power mechanism was bound up inside the door assembly. You were able to manually force the door open and cut the stuck cable, allowing the door to operate as a manual slide instead. The owner believes this design flaw affected 2019-2020 models and should have been recalled, since a similar issue was documented before these model years were built.

Your passenger side rear door unlocked and opened by itself in the middle of the night without any warning. The doors were locked before this happened, and it wasn't caused by accidentally pressing a key. This suggests a potential issue with the door locking mechanism or electrical system that controls the locks.

Your fuel door hinge is rusting and breaking, which is preventing your rear passenger door from opening automatically. The hinge appears to be poorly constructed and not durable enough to withstand normal use. Fixing this will likely involve replacing the fuel door hinge and possibly adjusting or replacing the door latch mechanism.
