2019 GMC SIERRA 1500 Exterior Lighting Problems

The screen on radio is so bright in the cab when backing is blinding when backing up and dangerous. No way to turn down the brightness.

2019 GMC AT4. PROBLEM OCCURS AT NIGHT. WHEN PUTTING THE TRUCK IN REVERSE, THE DISPLAY MONITOR ON THE DASH TURNS TO FULL BRIGHTNESS (AND CANNOT BE TURNED DOWN). IT IS VERY HARD TO EVEN SEE THE SIDE MIRRORS DUE TO THE BLINDING BRIGHTNESS OF THE DASH DISPLAY. THERE NEEDS TO BE A FIX TO THIS PROBLEM AS IT MAKES BACKING UP AT NIGHT VERY CHALLENGING. *TR

WHEN BACKING UP IN THE DARK THE BACKUP CAMERA GOES TO FULL BRIGHTNESS AND IS VERY DISORIENTING AND MAKES USING YOU MIRRORS VERY DIFFICULT SINCE YOUR EYES ARE ADJUSTED TO THE DARK. USING THE BACKUP CAMERA SCREEN IS USELESS DUE TO HOW BRIGHT IT IS. HAPPENS WHEN VEHICLE IS STATIONARY OR IN MOTION.

PUTTING VEHICLE IN REVERSE TURNS THE INTERIOR DISPLAY BRIGHTNESS (REVERSE CAMERA) ON AS BRIGHT AS IT GOES, LIKE A FLASHBULB GOING OFF RIGHT IN YOUR FACE. THIS IS ESPECIALLY DANGEROUS AT NIGHT AND LEAVES TEMPORARY BLINDNESS WHICH AFFECTS THE ABILITY TO SEE OUT INTO THE DARKNESS AFTERWARDS. THERE IS NO ABILITY TO ADJUST THE BRIGHTNESS OF THE INTERIOR DISPLAY. I CAN EVEN TURN THE DISPLAY OFF AND SHIFTING INTO REVERSE TURNS THE CAMERA BACK ON WITH MAXIMUM BRIGHTNESS.

THE BACKUP CAMERA ON THE INFOTAINMENT SYSTEM IS BLINDINGLY BRIGHT AT NIGHT. WHEN YOU PUT THE TRUCK IN REVERSE THE BACKUP CAMERA POPS UP ON THE INFOTAINMENT SCREEN AND BLINDS YOU MAKING IT A HUGE SAFETY HAZARD AS YOU CANNOT SEE ANYTHING OUT YOUR MIRRORS. THIS NEEDS CORRECTED SO THERE IS A BRIGHTNESS CONTROL TO ALLOW THE SCREEN TO BE DIMMED SO THAT YOU CAN SEE WHEN BACKING UP.

TL* THE CONTACT OWNS A 2019 GMC SIERRA 1500. THE CONTACT STATED THAT THE LANE DEPARTURE SIGNAL WAS SUPPOSED TO BLINK THREE TIMES, BUT IT ONLY BLINKED ONCE. IN ADDITION, THE LANE DEPARTURE SIGNAL FUNCTIONED CORRECTLY INTERMITTENTLY. THE VEHICLE WAS TAKEN TO DEMONTROND BUICK GMC (14101 NORTH FWY, HOUSTON, TX 77090, (281) 607-1716) TO BE DIAGNOSED, BUT THE FAILURE COULD NOT BE REPLICATED. THE DEALER STATED THAT THE VEHICLE WAS FINE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 4,400.

WHEN PUT INTO REVERSE, THE SCREEN FROM BACKUP CAMERA IS OVERLY BRIGHT MAKING IT DIFFICULT TO USE THE SIDE MIRRORS AS THE OPERATORS NIGHT VISION IS COMPROMISED.
