Check coolant level
I know you posted this a long time ago, but the same message just popped up for me too. I have an entry level CLA 250 2014 model and it's around 50K miles. The nearest Mercedes Benz dealership is an hour away from where I live. I'm not asking for any mechanical advice, but did this happen to you during the winter? Ever since I bought this car, it always malfunctions during the winter. Every time I ask the dealership, they always say that everything is fine. Do you have any of the same problems?
