Hello everyone,

I own a 2018 CX5 since about two years. One year ago the infotainment system began having problems (black screen / random restarts). Went back to the dealer which replaced the CMU. The problems seemed to be resolved until a few months ago. The same problems started occuring, but I noticed they only occur in wet weather conditions or directly after a period of wet weather. I already removed the nav sd card, disabled bluetooth. The problem keeps occuring. Today I tried to search for leaks but couldn’t find one. Dealer can’t find the problem either amd asked my to create a journal to keep track of the problems. Does anyone have any idea what might be going on? I am hoping to find the cause for this problem, so the dealer can fix this. One thing that crossed my mind today: the sharkfin antenna was loosely connected to the car (this has already been fixed), could a faulty antenna cause these issues? Curious for answers, thanks !

 

It wouldn't hurt to double check it.
