One problem related to headlights has been reported for the 2003 Toyota Highlander. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2003 Toyota Highlander based on all problems reported for the 2003 Highlander.
Headlight lenses have become progressively translucent blocking significant light energy from vehicle to operate vehicle in a totally safe manner. (incident date and odometer reading not applicable in this case. ) some internet web sites suggest drilling holes in the headlamp fixture to fix problem. I believe it is a safety issue and that the manufacturer should stand behind getting the problem resolved. This problem is not exclusive to Toyotas as I have observed other brands of vehicles with the same safety problem and may be related specifically to a headlight fixture manufacturer shared by other vehicle manufacturers. Thank you for allowing me the opportunity to be heard.
