[xxx]. The engine intake manifold on our 2012 mercedes E350 (64,000 miles) exploded with enough force to bend the hood up 2 inches. It was a damp cold morning & the engine had not been started in 12 hours. The car was not locked & the key fob was nowhere close. The fuel level was under 3/4 full. This happened when wife went to get something out of the car and when she pulled the passenger door handle to open - b o o m !!!! if this happened 30 minutes later, I would have been under that hood checking the fluid levels for a trip to san francisco. I would have been seriously hurt or killed!. It was towed to mercedes-benz of carlsbad, carlsbad California on [xxx] & they have not been able to identify the cause.

Recently, I have noticed a strong gas smell emanating from the rear driver’s side of the vehicle. Upon further research, I discovered that there was an open recall affecting mercedes e-class vehicles of the same year for a similar issue. However,my vehicle’s VIN is not included in this recall. Given that my vehicle is experiencing the same problem described in the recall, I am concerned about the safety implications and believe this matter warrants immediate attention. I would like clarification on why my vehicle is excluded from the recall despite exhibiting the same issue. Additionally, I would like to know if I am expected to pay out of pocket for repairs related to what appears to be a manufacturing defect acknowledged by mercedes-benz for other vehicles of the same year and model. I kindly request that this matter be escalated for review, and I look forward to your prompt response. My goal is to ensure the safety of my vehicle without incurring unfair expenses for a known issue.

I am the owner of a 2013 mercedes-benz E350 and am writing to formally express my concern regarding a persistent fuel leak issue I have experienced with my vehicle. Over the past months, I have spent more than $4,000 attempting to address this problem. Repairs have included the replacement of the fuel canister and the fuel pump. Despite these efforts, the vehicle continues to leak fuel from the area near the rear right tire, both when the vehicle is in motion and when it is parked. This issue presents a significant safety risk, not only to myself but to others on the road. I am aware that there is an existing recall for the 2014 E350 model related to similar fuel leakage problems. Given the similarities in design and the nature of the defect, I strongly urge mercedes-benz to investigate this matter and consider extending the recall to include the 2013 E350 models as well. I believe this is a critical safety matter that warrants immediate attention to prevent any potential accidents or hazards. Thank you for your time and consideration. I look forward to your response and to a resolution that prioritizes customer safety.

Pzev fuel tank leaks at top but is not repairable. Replacement requires complete tank replacment which is not economically feasilble. This forces owners to continue to operate vehicle with fuel leakage since repair of the tank is not possible. In older models a simple gasket change would resolve such leaks, in the pzev tank leaks can not be repaired and thus are left uncorrected. Many of these vehicles are now owned by minority owners who are unable to pay $5000 to repair a defective design. Mb refuses to support owners.

I noticed about to 6 months or less that my car would shut off or stall after starting ignition and also hearing water sloshing behind the dashboard and the radio does not work and the rear camera goes on/off which is safety hazard, and the engine symbol remain lighted up even after checking all components. Also, on a few occasion my floorboard in the passenger back seat would be soak and wet. I took the car to my mechanic, and he inform that the drain valve was not working properly. After doing some research on the internet I found that this particular incident was happening in several of mercedes years 2009-2011 e50, that it was a recall on the water drain system.
