Mine also started after recall flash. Took to dealer and they reflashed with new update fix. 4low worked in their parking lot. A month later went to use my boat and service light is back on. Taking to dealer again and see what they say. Hey jeep get your software updates right before telling people of recall. This is a second time chrysler has issued recalls to me and did not resolve problems without several trips to dealerships. I have owned jeeps for 30 years maybe its time to look elsewhere.
