Hi, yes, I bought a new battery (but mine was old) and all strange things did not accur anymore. If you have strange things happen, check your battery or if its not an old battery, than clean the battery where they get attached to give power (sorry don't know the name for it). Another issue could be water related. Check the forum for that. Another problem I was told here is the RCM, again check the forum, there are many threads with pictures about this issue. I hope this helps.
First check the simple things like battery and than go from there. I would not go to the Dealership because these guys have no clue and you pay lots of money!!!
I hope this helps.
