s550 code p0420

Hello all i am very confused and maybe someone from the support group can help. my S550 check engine light came on and i got the code of p0420, which we all know what that code means however i thought cats go bad very late into the years of the car this is a 2015 with 61k miles on it. furthermore, the car was driving a bit sluggish i will admit. a mechanic told me try to put in Cataclean and i did the car started driving with so much more power however the check engine light is still on. i really want to know what could be the issue being that cats go bad so late into cars like 90k-100k miles on top ( please forgive me if i am not too car savvy with descriptions but some help would be nice if anyone can thank you guys
