In recent months we have ocassionally smelled gas for a few moments at a time. It dissipates quite soon. My dealership looked at the car recently, test drove it for a few kilometers, and couldn't duplicate the problem . I was told the mechanic checked the system (visually I expect) for leaks. We're starting to think that it occurs for a few seconds upon starting the car, after it has been stopped for a half hour or so. Someone said the wet cool weather of autumn might have a bearing on this. Anyone any ideas or experience with this? TIA!
