I have an AWD 2012 Suzuki Kizashi that has approximately 129,000 miles. I have taken really good care of this car since purchasing it in 2014 with only 24,000. It seems awful early for the converter to be going bad. No recalls that I know of. The only major problem with this car has been having the heater core replaced last year. Does anyone have any insight as to why the converter could go bad so soon? Thank you.
