2024 Chevrolet Trax

Ambient light sensor malfunctioned on my 2024 Trax. It would flicker on and off in daylight when in the auto lighting headlight mode. After checking Reddit, many other owners are having the same issue. Chevrolet bulletin 24-an-001 has a direct fix. Avoiding flashing other drivers is important, as this indicates imminent danger is near.

Headlights are flickering and blinking intermittently along with the green headlight indicator blinking in gauge cluster. Seems like the automatic headlight sensor is unable to detect outer darkness level and fails to keep headlights on or off. Issue happens in sunny and partially cloudy days after the car exposed to sun for 5-10 minutes depending on the strenght of sunlight. This seriously confuse the drivers of incoming traffic especially in the crossings and intersections as blinking headlights means "i give you way" and may lead to accidents and other incidents.

The automatic lighting control module is malfunctioning and causing my headlights to turn on/off rapidly in multiple different lighting conditions. Weather the sun is up/overcast or even at night if I’m close enough behind a vehicle from the reflection of my headlights it causes the sensor to turn the lights on and off. I was pulled over by a local sheriff the other day because he saw it happening during the day and that’s how I initially realized it was happening. If anything it’s an obvious safety risk for the distraction it causes to not only me but other drivers on the road. And I am always constantly checking the light on my dash to see if my headlights are actually functioning(lighting) when they should be. As another note there is many other people having this same issue that I’ve seen on Trax forums.

The auto lights during the day are defective. They work perfectly at night. On a sunny day they will be on, then turn off when I drive down a road with shade from a tree. Not only is the interior light flashing, my head and taillights do as well, causing concern and distraction for drivers around me. I took my Trax into the dealership shop several times. They changed a sensor, but that did not change anything. The sent a request to GM for a "fix" but there only suggestion, after more than 6 months was to drive a different Trax to show me all of them do that, that that is how they are made. I am just exasperated! Lights should not turn off when you drive under a shade tree, but stay on when it's bright and sunny.

Ambient light sensor defective since vehicle was new. It would turn the lights on at dusk and back off at dawn but was confused by direct sunlight on sunny days. The the lights would switch from DRLs to headlights/taillights whenever direct sunlight hit the sensor and then immediately switch back to DRLs when any shadow crossed over the sensor causing the lights to flash. this causes other drivers to flash their lights back and can be very distracting. After replacement of the sensor, the problem went away.
