Tl* the contact owns a 2015 ford f-150. the contact noticed that the trailer hitches would not latch. there were no warning indicators illuminated. the vehicle was taken to bergstrom ford of oshkosh (3355 jackson st, oshkosh, wi 54901, (920) 238-3417) where it was diagnosed that the trailer hitches needed to be replaced. the vehicle was repaired. the manufacturer was made aware of the failure and advised the contact to file a complaint with nhtsa. the failure mileage was 72,000.
2015 ford f-150 manual on page 263 has instructions for proper setup of an equalizing hitch for towing a trailer. the instructions call for return of the front fender height 25% of the way from height when loaded with trailer to height with no trailer. this is the opposite of recommendations of the hitch manufacturer who recommends front fender height to 75% of the way from loaded to unloaded condition. in the words of the hitch manufacturer "why would you put on an equalizing hitch and not set it up to do what it's intended to do?". the result of the instructions in the ford manual would be inadequate equalization, and therefore loss of steering with a resulting potential for accident. i think this is just a typo, but have been unable to find anyone at ford who will listen and find someone technical enough to check it out. *tr
