try this site. enter your VIN number up top and see the service bulletins for your car.Here's what I can find by searching Smart Trunk TSB Smart Trunk Technical Service Bulletin "Smart Trunk TSB" "Smart Trunk Technical Service Bulletin" "Smart Trunk" TSB .... 493 results with the words Smart and Trunk and Technical and Service and Bulletin. So, any help would be appreciated. I do think they mentioned that there was one when I talked to them about it in April 2020.
