There are 3 owner-reported lighting complaints for the 2018 Alfa Romeo Giuliain NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
At night, with headlights set to AUTO, the headlights (right and left) will randomly turn of and on while driving. This could render my vehicle momentarily invisible to other drivers around me. Dealer confirmed the issue is the headlights. 70,000 mile service was just completed prior the the issues fist occurrence. No warnings or messages before the first incident.
When going over road bumps or hitting a pothole, the headlight adjusters pop out of alignment and is unable to be adjusted. This is the second headlight replacement for the same issue after my first pair of headlights were replaced under a tech service bulletin. The replacement lights which should have fixed the issue did not fix the issue and I know have a second pair of headlights that need to be replaced. This is a safety hazard as the lights point upward into oncoming traffic when the adjuster/clip breaks internally.
THE LIGHT CONTROL FOR THE 2018 ALFA ROMEO GULIA HAS ALWAYS BEEN SET AT 'AUTO'. OVER THE PAST FEW MONTHS, WHILE THE CAR WAS IN PARK IN OUR DRIVEWAY WITH NO KEY FOB NEAR IT AND NO ONE TOUCHING THE VEHICLE THE HEADLIGHTS WOULD BLINK ON AND OFF. THIS WAS OBSERVED ABOUT 4 TIMES OVER THE PAST 2 MONTHS. RECENTLY, WHILE DRIVING THE INTERIOR AND EXTERIOR LIGHTS SUDDENLY WOULD DIM, BUT QUICKLY RESTORE. ON ONE OCCASION ABOUT 1 WEEK AGO, THE INTERIOR LIGHTS REMAINED DIM BUT I WAS ABLE TO RESTORE TO THE PRIOR SETTING BY ADJUSTING THE CONTROL ON THE DASHBOARD. LAST NIGHT, WHILE DRIVING ON LOCAL STREETS HAVING JUST EXITED FROM A HIGHWAY, THE INTERIOR AND EXTERIOR LIGHTS TURNED COMPLETELY OFF FOR ABOUT 2 SECONDS, WENT BACK ON THEN TURNED COMPLETELY OFF TWO MORE TIMES AND WENT BACK ON. UPON ARRIVING AT HOME, THE CAR WAS TURNED OFF. THE AUTO SETTING FOR THE LIGHTS WAS NOTED AND THE OWNERS MANUAL WAS REVIEWED TO CONFIRM THE POSITION OF THE AUTO SETTING WAS CORRECT. I TURNED THE CONTROL SWITCH A FEW TIMES WHILE PARKED IN MY DRIVEWAY AND THE LIGHTS TURNED ON AND OFF PER THE SETTING ON THE CONTROL. I RETURNED THE SETTING TO AUTO. A CALL TO THE DEALER SERVICE DEPARTMENT TO INQUIRE IF THERE HAD BEEN ANY OTHER COMPLAINTS INDICATED THERE HAD BEEN NO OTHER REPORTS TO THEM OF THE LIGHTS IMPROPERLY FUNCTIONING WHILE PARKED OR WHILE DRIVING.
