Spontaneously the left back side door has failed to close on several occasions. It happened first while parked in the driveway and I had to use my body to get it shut. I went to have it checked out at the Volvo dealer and when I described it they told me several people had been in for service with the same issue. They told me one lady had it on 2 doors and another realized her door was open when it flung open mid-drive. They told me the car was just cold and that I needed to make sure the handle was flush with the door when trying to close it. The next day, I picked up my dry cleaning and hung it by that door and drove away. I wasnt aware it failed to latch yet again and only realized it when it flung open while I was driving on the road. This is the same door next to my sons car seat which is terrifying to think about. I ensured the handle was flush and it still wouldnt close until I hip checked it shut 3 times. Without a clear cause or reasonable solution (it is not reasonable to expect this just because its cold out), it is imperative that Volvo address this on behalf of the safety of its customers.
