The slave cylinder in my 2016 Manual PP Ecoboost failed at 17K miles. Dealer said the part is back ordered, looked online at all dealers in AZ and it shows as not in stock. Dealer telling me it could be weeks before they can get a replacement. At least I'm getting a rental since it's a warranty item. But, they can purchase from other dealers (only) if they can find it, so, looking for FR3Z 7A508B, lots of them for 5.0L and 5.2L, none for the 2.3L. TIA.
