Catalytic converter was defective in October 2022. Had to wait to get part in. Vehicle taken to dealer for repair in December 2022/ Told that the second catalytic converter needed to be repaired. I stated that I was not aware that cars had two catalytic converters. Parts were ordered and replaced. Engine light came back on-again October 15, 2024. Portable CO detector in car was beeping when engine around time engine light came on. Not covered by warranty or insurance. A new car with 55, 000 miles to date should not have these issues.
