COMPONENETS FAILING: Passenger side headlight and blinker keep failing. Driver side running light keeps failing to illuminate. Driver side rear brake lights keep failing. Rear passenger side reverse light and blinker failing to illuminate. SAFETY: I have no way to safely drive in the dark or daylight because the blinkers and headlight are failing to work properly. INSPECTION and CONFIRMATION: The problem keeps reproducing itself about every month or so since purchase, July 4th of 2022. The dealership has attempted to work on the problem four times already. Three times at the same dealership and once at another auto shop. The dealership is the only one that has inspected it. They have been in communication with the engineers on multiple occasions. KNOWN PARTS REPLACED AT THIS TIME: The BCM, wiring harness, fuses, and fuse box have all been replaced since September of 2022 to now, March 7 2023. WARNING MESSAGES RECIEVED: The only warning messages I have gotten are blinker failure, break light failure, head light failure.

I was stopped, and given a warning by a police officer for having no tail lights whatsoever. All other lights were functioning, and they had been fine the day before. These vehicles have four identical stop and tail lamp bulbs. I tested with my multimeter, and found that there was current at the socket. I replaced all four bulbs. Upon inspection, I determined that a SINGLE bulb of the four had a broken filament. It seems ridiculous that one bulb failing should cause the other three to go off duty. What is the point of two bulbs on each side, if they all quit when one dies?
