“I own a 2004 Gmc Sierra pickup with 6,700 miles. I am experienceing a imtermintent problem with the turn signal/hazard lights. When I activate the left turn signal the hazard lights begin to flash. I have taken the truck to the dealership for repairs, after waiting two months for the problem to occur at a time I was near the dealer. They replaced the multi function switch and two days later the problem is still there. I continue to work with Gmc directly and the dealership to seek resolution but am being told that unless they can see the problem happening they cannot do anything. …”
