During inclement weather (snow and rain) when windshield wipers were necessary for visibility, the wipers would either move very slowly or intermittently and stop in the middle of the windshield despite the wiper control set to high and not on the intermittent setting. this would occur when the vehicle was at idle and in motion, any speed. this occurred between march 2016 until a new wiper motor assembly was purchased and installed within the first week of july 2016. i did not receive any notice of recall from gmc however i did discover a recall through www.autozone.com (# 15789: service parts safety - windshield wiper motor failure - (oct 26, 2015)) . on 10/27/2016, i called gmc to see if reimbursement was possible and they could not assist me due to the bumper to bumper warranty being expired. vehicle was purchased certified used through auctiondirectusa on 10/8/2015 with an ameriplus warranty (36 month/ 36000mile).
