The repair guy got this code u0121 mltblx trc c cnctc for my Samsung SM3 2014 car. The car had stop working, I thought, it is battary, but even new battary did not help. It comes up with several fault messages like Fault power stearing, fualt breaks, fault battary recharging, etc. Any ideas on why new car will suddenlly stop working like that?
