One problem related to engine stall has been reported for the 2013 Mercedes Benz C250. The most recently reported issues are listed below.
I was experiencing an engine stall when starting my vehicle and a rattling like noise coming from the engine as well in early January 2018. My engine light sensor came on about 2 days later. I took my car to mb long beach and was advised that I needed to have the camshaft adjusted which would cost me approximately $4k+. It was further explained that this issue was due to a crack in the shaft and the oil is not being properly dispersed. After further investigation on my own behalf, this is an engine manufacturer defect and there are several consumer complaints regarding this same issue. After calling mb USA several times, I finally received a call back stating, I could receive a "1-time, 10% off the total cost of the repair. If this was a consumer related vehicle repair negligence then the consumer covering the expense would be the right thing to do, but when this is a defect from the manufacturer and mb is aware of it then this expense should be one that should cover.
