Brakes Failed problems of the 2020 Lincoln Aviator

Brakes failed when driving down my driveway, which is a steep hill. Received six error "service now" messages: service advancetrac, check brake system, hill descent control fault, park brake malfunction, pre-collision assist not available. Was able to roll to a stop and had to call tow truck. Subsequent conversation with dealer service dept , was told recall 20u29 applies. Gave me a dozen 'codes' for faulty/affected systems on car before I stopped him because I did not understand the acronyms. I have searched and cannot find a recall by that number. The brake failure was scary and I am glad it occurred at home.
