Hyundai Elantra 2013 problem

Question by Alex Pleitez posted 6 months 2 weeks ago in E-Class

I have the Check Engine light on, and the scanner shows three codes: P2069, P2271 and P2169. The mechanic suggested changing the catalytic converter. But researching those codes, I think the problem would not go around. Does someone help me with an orientation? I do not want to change the catalyst without being damaged
