Brake Electric Antilock problems of the 1999 Hyundai Sonata

Cruise control was activated at 60 mph when applying brakes to avoid an accident, but consumer lost control of vehicle and hit retainer wall head-on. Vehicle still maintained 60 mph, and brakes did not deactivate cruise control. Eventually, vehicle stopped after consumer turned it off. Passenger's side air bag did not deploy/ seat belt did not lock up, and cruise control would not deactivate.

Alternator went out which made the electrical system to go out. Entire dashboard was not working, also, abs brakes and engine check lights kept blinking. There was an electrical smell. Dealer replaced alternator.
