I bought my first brand new GMC and it was a 2015 Canyon on late Nov. 2014. About less than 3weeks later, while using my windshield wiper during a raining day, the driver side blade started to rub against the windshield making the loud noise sounded like the blade need to replace. I drop the truck off at the dealer and while showing them my windshield problem, I notice the two rubber lines on the roof is coming off the roof. This brings horrible feelings to me because this is my first brand new vehicle ever. I am in contact with GMC now and hoping they would give me a replacement truck. Will update...
