Mazda CX-9 Rust on Exhaust Pipe
I bought brand new CX-9 GT 2.5 months back. After driving for a week, I noticed a rusty looking marks on the exhaust pipe, which I guess came along with the fuel exhaust.
Is it normal for a new car showing rusty lines? You could actually wipe the rusty marks with hand.
I informed the dealer after a week he says it is because of condensation and should go away after break in period. But after 2000 miles I still see the same rusty fluid coming out. I left the vehicle with dealer yesterday and he said he is going to take pictures and will send it to mazda.
I don't know if it is a faulty pipe or something else going on.
