During the manufacturing process, particles was trapped between the fuel and rail injectors, which is causing a fuel leak. A fuel leak in the presence of an ignition source, such as hot engine or exhaust components, increase the risk of a fire.
My vehicle's cylinder head needs to be replaced due to a leak in the valve seat. It is available for inspection upon request. My safety and the safety of others were at risk because the engine of the vehicle could of failed at anytime while the vehicle was in use. This could have lead to an accident. The problem has been confirmed by the dealer and the dealer is recommending I replace the cylinder head. The dealer's service center had a certified technician perform a diagnostic test on my vehicle. There were no warnings, messages, or symptoms prior to the check engine light coming on. I brought my vehicle in to the dealership for a diagnosis of the check engine light as soon as the check engine light appeared. That is when I was informed that I needed to replace my cylinder head.
Approximately several weeks ago, the check engine light illuminated in my vehicle. No issues were present at that time. Shortly after, approximately a week later, the vehicle began to stutter when reversing or driving on surface streets after being on the highway. The vehicle also would stall after the check engine light flashed several times. The vehicle would need to be turned off and turned back on to accelerate correctly and not stall. This has not been inspected by the dealer yet, a service appointment has been made. Mercedes recently recalled other models due to a water intrusion issue, but this model was not included, however it is exhibiting nearly the exact same symptoms.
