I notice a smudge on the left "leg" approximately 4.5 inches from the top when I took delivery. Thinking I could clean or polish it off, I just let the matter go.
It skipped my mind completely and it was about 2 weeks after that I tried unsuccessfully to remove the smudge. I showed the problem to the dealer and he was kind enough to replace it under warranty.
Now I am a happy camper waiting for the ECU upgrade hoping to get the "yo-yo" problem fixed.
