I had a 2013 Ford CMax using the Blue Ox Baseplate BX2639 and have experienced loosening of the attachment bolts which have been torqued twice by different companies. Recently my Ford dealer noticed frame damage (not caused by loose attachment bolts). Specifically, the attachment flange of the upper support frame to the uni-body of the vehicle (toward rear of car next to baseplate mounting bolts) failed. This was a vehicle frame failure, not a baseplate failure. It appears due to metal fatigue as a result of forces applied to the support frame through the baseplate while towing. I DO NOT KNOW if this issue is an isolated occurrence on my car or not. The baseplate attaches to the vehicle with six bolts (three on passenger side and three on driver?s side at the top of the baseplate). The baseplate has approximately 6-8 inch drop to the baseplate cross bar (attachment point for RV tow bar). There are no attachment points at the bottom of the baseplate, or its crossbar, to the vehicle.
If you own a Ford CMax using this baseplate, you may want to inspect for loose attachment bolts and the upper support frame flange (toward rear of car next to baseplate mounting bolts) for possible vehicle metal fatigue or damage. Also inspect the lower frame support (which is factory welded to the upper support frame) for metal fatigue or damage. This inspection requires removing the front bumper assembly of the vehicle.
