Chronological view of owner reports
This problem has occurred to me now twice. Both occurrences were on very cold days where the temperature was below 20 degrees F. The car starts promptly and runs, but the entire dashboard electronic instrument cluster is non-functioning and dark . In this condition, you cannot tell your speed, engine rpm, fuel level, engine temperature, or any mileage numbers. The turn signals also do not work. The headlights and the iDrive screen and the climate control were all lit properly and functioned. I did not think to check the brake or tailights, unfortunately. Multiple restarts of the car had no effect, and so I drove home without the dash functions. After the car sat overnight in my garage (which is somewhat warmer) the dash lights returned to their proper function.
Drivers left front daytime running lights failed after <4 years from warranty replacement. 3rd set of lights in under 7 years on this vehicle.
Front headlights were replaced under warranty after daytime running lights both stopped working in Oct. 2021. Similar problem now on 9/4/25 approximately 4 years later, and BMW is leaving me to foot the bill on a barely 7 year old vehicle, forcing me to have 3 sets of lights on a car that is 7 years old.
headlights flash due to possible faulty switch. very bad safely problem that affects other cars
AS I WAS MAKING A 10 MINUTE DRIVE, ON A HIGHWAY ABOUT 30 MINUTES BEFORE DARK, IT JUST STARTED TO SNOW. SUDDENLY ALL OF THE FRONT SENSORS STARTED TO FLASH "TROUBLE" ON THE DASH. I CHECKED THE FRONT OF THE CAR AND ICE HAD FORMED OVER THE SENSORS AND HEADLIGHTS. THAT RENDERED THE CAR UNSAFE TO DRIVE IN THE DARK SINCE THE HEADLIGHTS COULD NOT SHINE THROUGH THE ICE. AS FOR THE DISTANCE SENSORS, I GUESS THAT IS A DESIGH FLAW AS A FUNCTION OF HOW SNOW PASSES OVER THE SENSORS. I BELIEVE THAT THE LED HEADLIGHTS DO NOT GENERATE ENOUGH HEAT TO PREVENT ICE FROM FORMING ON THE LENS OF THE HEADLIGHTS.
