Engine started misfiring and would go into limp mode so I brought it to dealership for diagnostic and was told oil was leaking from the camshaft sensors into the engine wiring harness and ECU. All of which needed to be replaced at a cost of over $6033 and the car has only around 50K miles on it. Several previous year Mercedes from 2011 and earlier have a recall on the camshaft sensors due to oil leaking from them into engine wiring harness and ECU however my year car which is 2012 has no recall on these parts even though they use the exact same camshaft sensors and have the same problem as the previous years which is oil leaking from them and destroying expensive parts that need to be replaced.

While driving 45 mph, the brakes were applied however, the vehicle would not decelerate. In addition, the steering wheel seized simultaneously and the contact lost control of the vehicle. The vehicle was towed to the dealer for diagnosis. T the manufacturer has been contacted and stated that they would look into the issue. The failure and the current mileage was 980.
