I’ve had this happen once, I have a ranger raptor that switched to 4 low in a parking lot. Luckily I was already at a low speed. It also switched the rear locker on. Turned truck off, goggled how to find lockers and turned it off. Had about 7500 miles when this happened. Got almost 17,000 now...
Last vehicle was black and I said never again, gets hot in the summer and shows dirt badly, got a cactus gray 24 RR and love it, hides dirt well and tons of comments on the color. Either way enjoy your new truck
