2017 GMC Sierra 5.3L 4x4. Active grill shutter failed at 220k kms. I replaced with a Dorman part from Rock auto, 225k kms and its failed again. First time I just had code U1510, this time I got code P059F and U1510. Initial replacement went fine other than breaking one of the clips getting the trim piece off the front to take the grill out... The shutter itself fit well, didnt have to force anything, all seemed free. It immediately fixed the code and worked fine for a couple of months. Question: could there be anything else causing these to fail or did I just get unlucky? Have they fixed the OEM part or am I better off buying another aftermarket part for 2/3 the cost? Last any tips for getting the trim piece under the grill/headlights off without breaking the remaining clips....
