I know people have had problems, but my personal experience has been good in the 2+ years I've had the X. I think if you lock your car when not in use, either keep the key far away or skip comfort access as an option, it holds up fairly well.

I put on about 5000 miles a year on the car and very often drive it under 5 miles. I also commonly leave it garaged for weeks at a time. Sometimes even a month without driving. No issues at all. I purchased a charger from my dealer thinking I would need it but still haven't even taken it out of the box yet.
