general problems of the 2010 Jeep Patriot

My Jeep Patriot 2010 turned on the head lights on without me to doing it and turned the lights off when driving.

My daughter called and said all of here lights were out both inside and outside Jeep. Windshield wipers did not work. Basically everything stopped working. She was able to start it and I told her to take it to the Jeep dealer in christianburg va. They checked it out and told her the control arm for the signals lights was broken but could not get a new one until Monday, this was Friday night. I told her to come home very slowly because it was raining. She made it home safely, I checked several Jeep forums and found out if you disconnect the battery and let the computer reboot it would fix the problem. Sure enough it did and saved me hundreds of dollars. Everyone should know this to keep from getting into trouble on the hwy. I have questioned the dealer in richmond about but they say they have never heard anything about it. The problem is there and some people know because they told me how to solve the issue. Please let everyone know about this issue both for safety and wasted money at a dealer.
