I solved this same problem on an older car a few years ago. Took care of the same issue on my 2017 Cadillac XTS Luxury. SOLUTION: You have to put resistance on the bulb wires in the form of a resistor or one of the old bulbs you replaced. I used one of the old bulbs. Painted it black. Tied it into the line (bulb wires) running to the backup lights. Just tuck the resistor or bulb up on top of the inside of the bumper. No one will ever notice it and problem solved.
