Should never have happened! We live in Florida, no rust!! Was expensive as we had to replace the entire muffler and catalytic converter as it is made that way by the manufacturer and we could only use manufacturer parts!

Converter was plugged and stalled the vehicle while we were trying to merge onto the highway. The car is brand new and having the new car experience. The dealership replaced the exhaust system but did not replace the oil which was contaminated, It changed to a gum like substance and probably damaged the engine. I've got about eight other issues but I don;t have the time to post them, I'm asking for a new engine next week. LOL. It sounds like a piece of sh*t.
