Headlight assembly, after about 4 years the headlight assemblies on the vehicle become fogged over so badly that you cannot see the road very clearly at night. This is due to the auto makers using plastic for the lense cover instead of using glass on the assemblies, if they used glass there would not be a problem, the headlight assemblies are just as important as the windsheild.
