New 2024 2500 Denali Ultimate at 904 miles. Mirror Blind Spot indicator works at random. Sometimes it notices a vehicle in the blind spot and sometimes it does not. It's about a 50/50 shot it will work. It misses semi trucks. Also at random it indicates something in blind spot and nothing is there. Took to dealer and they say they can't replicate the problem. It is a shame at $100K the blind spot indicator is hit or miss. Just wandering if anyone else has this issue and possible fixes.
