The right head light on my 2014 Acadia Denali went out. Kutztown Auto repaired it in just a few hours while I went to breakfast. The service was great, but the cost of the part was insane. If GM is using light bulbs that cost all but $300.00 it seems to me that they should last forever. What idiot engineer designed a light system that requires you to remove the inner fender? What is wrong with opening the hood and reaching in to unscrew the bulb? Not impressed with the engineering. Kutztown Auto is great...GM not so much. Also GM said they would fix the faulty blind spot sensors. It has been over a month and still no parts for that fix. Again not impressed with GM.
