Automatic light sensor does not sense daylight for 5 mins and 23 secs at the last timing. in a daylight drive of 12 miles, the car turned night-time lamps on and off 6 times. dealer says it is working as designed. this has just started to happen the last 12 days. no light settings have been changed since they were set when i purchased the car. i was told by sholz cadillac repair to wait for the lights to sense the change before driving. however, what do i do when entering and exiting a tunnel? when placed side by side with a gmc xuv with an automatic sensor, the gmc senses the difference in light in 3 seconds. this delay in my cadillac is certainly a safety hazard. *nm
