Purchased new 2015 MB e400 in 12/2014 MB issued a bulliten in 12/15 (1 year later) indicating that the engines may experience a problem with the timing belt harness which may cause engine failure. We have the exact same issue now at 69k miles and MB refuses to acknowledge the issue claiming i need a new engine. I cannot use the car for fear of engine failure which may cause death or serious injury
