2011 Volvo C70

Both cabin doors (initially only the passenger door) will pop half-open from a closed position while driving, particularly with the windows and/or roof down. This occurs seemingly at random and regardless of lock position or firmness of door closing. The effect is a startling noise as the door opens slightly, the window retracts, and the cabin lights and door warning alarm engage. This can pose a hazard to safe driving. Neither door has as-of-yet come fully unlatched, remaining instead in a half-latched position until the driver can pull over and close the door fully once more. Lubrication of the latches by a mechanic did not alleviate the issue, and a cursory browsing of Volvo forums suggests that this is a common issue for which no recall or service bulletin has been issued.
