Hi all,

our Cx50 has been displaying an “Auto light malfunction” intermittently for a week and now, it permanently displays it and tells me to use manual light control. I also noticed (maybe related) that the HUD has completely stopped working even toggling it on and off in the settings. Any thoughts? I’m wondering if a harness is loose somewhere. I did also wash the car in case any sensors were dirty, but no change.

I haven't had this issue myself, but like many computer related issues, try disconnecting the car battery for a half hour and let everything reset. Just an idea that I would try. Otherwise take it to the dealer so that they can diagnose it while the error is being displayed.
