What owners said

2014 Mercedes Benz E350 Sunbury, OH Fire

FUEL/PROPULSION SYSTEM

Vehicle subframe corrosion (manufacturer extended warranty offered). Rear brake lines corroded/leaking. Vehicle leaks fuel; steel fuel line corroded. Vehicle has about 105k miles. Minor fire started when yard maintenance came in contact with fuel saturated ground where vehicle had been parked/moved out of the way just prior. With rear suspension subframe springs corroded, vehicle bottom can contact road surface while driving, scraping steel exhaust with fuel present. EXTREMELY dangerous. Local Sunbury Ohio Mercedes dealership inspected then offered subframe replacement. Stated it was leaking fuel and not hydraulic fluid we originally thought. Brake, suspension and fuel line corrosion repairs were quoted in excess of $4,000, which was a "great deal" according to them "because the subframe would already be removed and would make it much easier."

Fuel odor is very apparent (while idle) but difficult to identify location. Same models seem to have recalls for fuel injectors/rails but not this specific VIN. I believe the issue might be of similar recall. I will have the car diagnosed soon.

My car displayed all of the issues listed below for the Electrical system recall. The fuel gague went "blank", other gagues acting irradical, the check engine light stay on, etc. My car make and model fall under this recall but have been excluded.

2014 Mercedes Benz E350 Flemington, NJ

FUEL/PROPULSION SYSTEM

2014 Mercedes e350 these models as well as those from2009-2015. Have recall on subframe but the brake lines rust out and deteriorate as mine has now done. If you go on line you tube etc. you will see the issue and all complaints. I had my subframe replaced under warranty at Mercedes of flemington. About 1 1/2 years ago. While it was being serviced they asked me if I wanted to replace brake lines for $1200 since they had this part out job would be easy. So this means Mercedes is well aware of the deterioration of these line the man at mb said the metal was inferior and this is result. On YouTube it was stated that individuals took mb to court or accountability for this but results were negative. Yet problem exists. If you breaks fail while driving it is very dangerous. Also I believe there is a recall for gas lines for my model 2014 manufactured from June and July. The brake lines on my vehicle are rusting as is gas tank. This also is dangerous condition should accidents occur the lines because compromised with rust can much easily rupture causing fuels to spew out causing possible explosive condition. I have pictures and can forward

2013 Mercedes Benz E350 Patterson, CA

FUEL/PROPULSION SYSTEM

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.
