The vehicle comes with a safety feature that automatically locks the doors when you reach a set speed, I believe it is 15mph. On several occasions, I, as well as two others that I am sure of, have had their arm on the door when the window was open and when the auto door locks engaged, it pinched us, and on three separate occasions, left bruises. I contacted Ram and their independent reviewers said there was no manufacturing defect. I agreed with that but told them that it's a poor design, and at least change the auto door lock feature to engage when the vehicle shifts into gear. Still not the best option but probably the easiest to just change the software. I currently have the auto lock feature disabled, but if this were to happen to somebody while driving, it could distract them long enough to hit something.
