There are 4 owner-reported lighting complaints for the 2015 Buick Encorein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The Body Control Module went out. I had it replaced. I do not know how long my back running light were out. I had brake and tag lights. There were no warning messages.
DURING THE DAY, DASH LIGHTS ARE NEARLY IMPOSSIBLE TO SEE. AT NIGHT THE DASH LIGHTS UP, BUT DURING DAY TIME DRIVING THEY ARE HORRIBLE. THIS COULD BE A REAL HAZARD WHEN HAVING TO LOOK DOWN & STUDY THE GAUGES & TAKE YOUR EYES FROM THE ROAD. WHY DOESN'T GM CORRECT THIS PROBLEM? THIS PROBLEM EXISTS WHILE DRIVING OR SITTING STILL DURING DAY LIGHT HOURS.
COMPLAINT REGISTERED YESTERDAY, BUT DID NOT INCLUDE PHOTOS WHICH I NOW WILL INCLUDE. 2015 BUICK ENCORE HAS A DIMMING ISSUE WITH THE SCREEN WHEN UNDER A CLOUD OR PERHAPS A TREE, WHILE MOVING OR STATIONARY. CANNOT SEE SCREEN FOR DIRECTIONS WHEN THIS HAPPENS. MUST TURN LIGHT SWITCH TO OFF IN ORDER TO HAVE SCREEN RETURN TO BRIGHTNESS. WHEN THIS HAS TO BE DONE, THE DAYTIME RUNNING LIGHTS TURN OFF COMPLETELY AND CANNOT TURN ON AGAIN ONE STOPS AND RESTART THE VEHICLE.
INFOTAINMENT SCREEN DIMS AUTOMATICALLY WHILE UNDER A TREE OR DRIVING UNDER SOME CLOUDS CAUSING THE DRIVER TO MANUALLY TURN THE LIGHT DIAL TO THE LEFT TO REGAIN THE BRIGHTNESS ON THE SCREEN. THIS WILL AUTOMATICALLY TURN OFF THE DAYLIGHT DRIVING LIGHTS. THIS OCCURS EITHER STATIONARY OR WHILE DRIVING. THERE IS A TECHNICAL SERVICE BULLETIN IN FOR ANOTHER MODEL OF THE BUICK LINE BUT NOTHING FOR THE ENCORE. THE TECH PERSONNEL INDICATED THE SENSORS ARE TOO SENSITIVE AND THERE'S NOTHING WE CAN DO ABOUT IT.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
