Windshield Wiper/washer problems of the 2001 Dodge Dakota

The windshield wipers on my Dodge 2001 quad cab hits on the hood as the wipers go back and forth motion. This is leaving a wear mark in the metal on the hood from where it continously hits. I informed my dealer where I bought the vechicle and they laughed at me. The problem is still taking place since I bought the vechile in 2001.

Taken to dealership several times,but they find no problems. Also rate of speed has been up to 55 miles when not working. No safety defect listed.
