Has anyone had problems with the wipers not working? Happened last week during a downpour, had to return home and swich vehicles. Took it to dealership on 12/27 and the column switch was replaced. Repeat incident this morning...wipers wouldnt work for at least 40 min. after car was driven. Have also had multiple trips to dealer for radio volume issues and not it just changes the radio station on its own. Wondering if the car is possessed!
