So I originally owned a 2016 Model X. Loved it except for problem with the doors. We would lock the X and go in to the mall and when we came out the doors would be open! WOW! So I thought it might be me pressing the key FOB in my pocket so I bought a key FOB box to make sure nothing could press on it in my pocket. Still happened so it wasnt me. Fast forward to today and I found a new 2019 X at a Tesla store in inventory. The salesman said that my problem with the doors randomly opening was not uncommon and that Tesla has since fixed that issue. Can anyone here verify that is true? Any other refinements that the 2019 will have over my 2016?
