One problem related to defogger has been reported for the 2001 Mercedes Benz ML430. The most recently reported issues are listed below.
At the slightest hint of humidity, side windows fog up to the point that you cannot see outside nor use side view mirrors. Following manual instructions on defogging just is too late. This failure of proper defogging is the worse than I have ever seen in my 50 years of driving and god knows how many cars.
