By the time My 2019 traverse had 14,000 miles on it, we had gone through 3 CATALYTIC CONVERTERS! Not normal, right? So I contacted Steve Ellison, the service manager. He was not only kind, but promised to help me get my car fixed. They found a weld on the tailpipe that didn’t hold from the factory installation. Steve felt like that was the cause of the converter failure. They replaced the tailpipe. I now have 3,000 miles on the new part and we are waiting to see if it is actually fixed.
