I was driving on the highway tonight going about 50 mph (with the top up) when the passenger side door became ajar. the interior lights came on, the window slightly opened like it does when you normally open the door, and a warning came on saying the door was open. it did not fully open, but was completely unlatched, i had to reach over and hold it shut while driving until i found a safe place to pull over. this has happened multiple other times, too, though this was by far the scariest and could have caused a wreck. i have never had this happen in any other cars i have owned and it seems to be a very dangerous defect, and i see other folks have had similar complaints online,
I have a 2012 c70, and the "door open" warning and interior lights come on and the door slumps slightly ajar (even the window drops like when you open the door). this happens driving at highway speeds. can be either driver or passenger side. doors are securely closed beforehand. i have also mastered the stop, lean and slam. it is so annoying and scary!
While driving normally on evenly paved roads my passenger door opens and a error message is displayed on my console. i have taken to the dealer who charged me $60. to check it on the computer but to no avail. the problem was not detected by the computer and the problem continues to exist.
