Welcome to the community, azooker! :) My name is Tricia, and I’m the U.S. Ford Customer Service Representative. I’m here to assist with any questions or concerns. I recommend taking your C-MAX to a Ford Dealer to get diagnosed. In the meantime, let me get this escalated. Please private message (PM) me your full name, VIN, mileage, dealer, and best daytime phone number. I’ll loop in a customer service manager for your region to assist. Tricia
