2018 Alfa Romeo Giulia: headlights failing or too dim

Filed Oct 13, 2026 · Electrical · NJ

On October 13, 2026, while driving my 2018 Alfa Romeo Giulia Ti home from work at night in dry weather, the vehicle’s lights began flickering and then the headlights went out while the vehicle was moving. I suddenly could not see the road and nearly had an accident. The problem is intermittent, and the lights later resumed operating, but the vehicle is unsafe to drive at night. This vehicle has a history of electrical problems involving flickering lights and loss of power. Alfa Romeo and FIAT of Maple Shade previously replaced the Body Control Module (BCM) for the same original problem, but the problem continued. The dealership later kept the vehicle for more than one month. Repair Order 032539 states that the vehicle had been towed in with “no power” and “electrical issues” and that multiple communication codes between modules were found for low voltage. The dealership replaced an aftermarket battery with an OEM Alfa Romeo battery and performed a proxy alignment, but the electrical and lighting problem has returned. The dealership also advised me that water had been entering around the windshield and affecting the vehicle’s electrical system. The windshield was subsequently replaced, but the lights continue to flicker and have now gone out while driving in dry conditions. I am concerned that moisture exposure, wiring, connectors, the replacement BCM, the charging system or another unresolved electrical defect may cause the headlights or other electrical systems to fail again while the vehicle is moving. No collision or injury occurred, but the sudden loss of headlights created an immediate risk of a crash. I am reporting this defect because the same safety-related electrical problem has continued despite replacement of the BCM, battery and windshield.

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.

My BCM was shorted out from water damage from outside the car. The dealer says he can't repair it under warranty because Alfa Romeo will not authorize him to. I have to pay 1200 out of pocket for something that should be covered by warranty. The car will start, but the front headlights won't go out, the turn signals won't work, brake lights don't work right. Check engine light comes off and several functions are disabled. I'm not sure the backup camera, blindspot monitoring are working correctly.

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.
