One problem related to starter has been reported for the 2014 Mercedes Benz CLA250. The most recently reported issues are listed below.
Air bags: frontal- sounds like the airbag lock spring is broken for no reason. I can hear the click when I turn. The digital dash reads "front left malfunction" and won'y go away no matter what I push. It also has an electrical system: starter assembly issue- the engine or transmission won't turn over a lot due to it. My car only had 40k miles.
