So, just a quick update...car is still at dealer, seems they couldn't find the cause of the chassis malfunction error message, just an "under voltage" code. But they did also note there is a bulletin to replace the aux fan to a bigger one...any other AH3 guys had this done? Mine is an M-Sport, I'm wondering if this is the same fan issue the M-Sports were having even two years ago, and they are replacing it just in an effort to fix the problem.
