I’ve seen a few posts on-line regarding pretty bad undercarriage rust on Macans and Q5s. Mine have both been rust free. Anyone here seeing rust issues?

No, and that includes 5 years in WI.

It is a problem, the front cross-brace, and the rear suspension cradle/subframe rust, because they are steel, with a poor-quality black paint job. Santrix (Macanforum.com) had to replace his rear subframe because it rusted-thru. All these cars will get some surface rust, and then eventually it rusts-thru.

This is a long-term-ownership problem for lots of Audis and the Macan. It is funny how VW/Audi/Porsche take some unusual steps (galvanized sheetmetal, lots of aluminum) to have rust free cars, then they forgot about two critical structural components.....

Thanks. Those are the posts that I had found on-line, but I simply cannot find much more. My 2019 Macan is winter driven in Canada and is absolutely rust free underneath???

Wow. I'll have to check mine out.
