Mine has been back to the dealer 7-8 times, it still leaks. The best you can do, is take the carpet out, and wait til it rains, that way YOU can trace it. These guys try to diagnose it by running it under a garden hose, it's just not the same. Mine leaked from the firewall behind the pedals and same area on the passenger side. Still have the passenger side leak. I even took it to another dealer for a fresh set of eyes. I think it is just beyond the skillset of anyone at a dealer. Design flaw somewhere. I wish I had noticed it leaking early enough in my ownership to have given it back under lemon law.
