I am writing in regards to a constant issue that a great percentage of people including myself, are experiencing with the engine within the 2017 Mercedes E300. The cam adjusters are easily going bad or are malfunctioning causing the timing in the motor to be defected which makes the car stall and shut off even while driving. Giving that this is happening to a great amount of people with this particular vehicle across the US, we feel that mercedes benz should take some responsibility in fixing this issue and not just post bulletins on the problem, cause its a safety issue and it costs people alot of money for a defect of this sort.

There is a pvc problem.It has to do with the emission I found that is a common factory problem.Part is back order.Other cars with this issue and same part number are being recalled.

Strong gas fumes smell from vehicle when parked. Issue starts around 50k miles. No lights on dash or anything. Multiple people in forums online experience the same issue around the same mileage. Some say it's a leak from fuel lines to the fuel pump.

Check engine light came on and then complete engine failure. Cracked #1 piston, and engine destroyed.
