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.

Service 4wd system message appears after n23 recall. Not fixed
Service 4 wheel drive. I was going through my winters checks, and engaged in and out of 4 low. I went through this procedure 3 times, properly. After the final test it came on. The green light that illuminates at the 4 low switch, also went out an will not come back on. Had the n23 update done, but the problem still exists. It will not go into 4 low, with a service light, and no green light at switch. Is this a fuse problem? It sure did act as one when it happened. The service guys at jeep are not being forth coming with any information, it's as though they are being ordered to be tight lipped. Anybody?
