I have a 2017 vehicle that after 2,500 miles had the check engine light go on and went into limp mode. After 3 times in 2 different dealerships, it was diagnosed with a broken catalytic converter. I was told that it was installed that way on the assembly line.
During the time the dealer was diagnosing the problem, they said I had dirty, smelly oil. During the time that the catalytic converter was broken and the oil was dirty and smelly, could the engine have been damaged?
