Seat belt retrieval spring (weak). i have both models 2013 and 2014. neither model has a strong retrieval spring, leaves the medal buckle loose and hanging in door jam, it gets slammed in the door. will deform at some further point and not engage. door locks. not sure if mandatory by regulation, door locks don't auto lock after car starts to roll forward. backup screen, just as you start to back up and, on the roll. the screen blocks out the top 1/3. it connects and tells you, your blue tooth items are connected or not. that message should be delayed until after being in reverse. the top 1/3 of the screen is pretty important. engine noise, a winding noise, on acceleration. i'll be in touch with toyota on this issue, (telsa motor). they are aware of the issue, friend had a drive unit replaced by toyota already in north nj
