A year ago my journey would have the radio come on after the engine was stopped and I left the vehicle. Alarm went off for no reason. Took it to the dealer and they said it was the battery and they replaced it. Almost a year to the day it has started doing it again. Took it to the dealer today and they said the battery is fine and after three hours of trying to figure out what the problem is they cleaned all the "connections" and sent me on my way. I got home, shut the car off and before I could get out of the garage the radio came on. After starting and stopping the engine several times the radio is off for now. Has anyone else ever had this problem? All the mechanics say they've never heard of this problem before. Thank goodness it did it to them at the dealer!
