On multiple occasions, more recently 03/28/2025, the windshield wipers would stop working. On 3/28/25 in pouring rain at night the front windshield wipers were working and then stopped. The rear window continued to work. I finally found somewhere to safely pull over and check fuses for front and back wipers. They were both good and I even swapped the fuses for front and back and the back wipers continued to work while the front would not. This continued on our our trip in rain and even the next morning the front wipers would not come on. An hour later driving (with the wiper switch in the OFF position) the front wipers came on. I switched the switch to on and they were functioning. This has happed several time in the 6 months of new ownership with the dealership denying they have ever heard of such a problem. As we arrived to our destination and telling the story to the other families we were meeting another family there said they just had the same exact problem on their 2024 Yukon denali on the trip too. This put 2 families in a very dangerous situation. As I google this problem there are multiple reviews of individuals with this same problem.
