Hi,
My friend has a 2015 Ford Fusion Titanium 2.0 AWD, Nov. 2014 production date. The issue is that during slow sharp turns there is a shudder coming from the rear transaxle. If we disconnect the rear electronically everything is fine, the car runs on FWD and there is only an error message that the AWD is at fault. Is there anyway to check id it's PTU?
