So the other day we were cruising along the coast, I stopped to take in the view, kids and wife stayed in the car. I got back in, put it in drive, pulled out of the parking area, and my wife flew out of the car. Evidently she cracked her door open, and didn’t say anything. What worries me most is that the car didn’t warn me her door was open. No audible dings. It works on driver side, but nothing on passenger. Any suggestions.
