No I do not. I use the X5 every day and I park in the garage. I have gone a vacation and left it for 3 days but that was several months ago. We did have a mouse in the garage a few months ago and I found it dead several days later in the hose of my shop vac. This was really surprising. I do live out of the city on a few acres that we farm for hay. I just was not aware that they would get into my car.
I was told to put some moth balls in the engine well and that will help keep them out of the car. I have several cats but they do not go into the garage. Maybe I need a barn cat for the garage! I will be setting some traps in the garage tomorrow.
