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."

I have a 2014 E350 Coupe. It has a major fuel leak that is immensely dangerous and could cause immediate harm/death if I did not remove the seat and inspect the fuel line. There is a recall on the 4 door model for reference. 15V‑792 / 2015110006 Recall Summary A fitting that joins the fuel hose and fuel feed line may develop a leak or completely disconnect. This can cause a fire hazard, fuel odor and potentially stall the engine while operating the vehicle. The fuel line fitting connecting the fuel hose and fuel feed line may be flared improperly, causing a possible leak or disconnection of the fuel line. Dealers will install the correct fuel line free of charge to resolve the concern. Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2014 E350 and E350 4Matic sedans manufactured June 4, 2014, to July 9, 2014. The affected vehicles were built with a fuel feed line that has a single flare fitting instead of a double flare fitting.
Fuel Leakage from the top of the Fuel Tank, leaking underneath the back seat. I'm told there was a past campaign to fix these issues in the Sedan Mercedes Benz E350. The problem was found by the fumes in my garage where I park the vehicle. My smoke and carbon monoxide alarm kept going off inside my house, and I had to call the fire department to help me identify where the fumes were coming from. No warning lamps or messages on the vehicle are present. When I called the dealership they told me there hasn't been a recall on the vehicles. I have had a diagnostic with the dealership.

On my way to work lady Tuesday 11/1/22 just a few blocks from my AT&T office I started smelling fuel. I thought it was an lad car next to me. Looking at the rear mirror I noticed a line of fuel following me. By the time I pulled a side and shut down the vehicle I lost the full tank. The vehicle was towed and is still at Mercedes Benz of Plano, Plano, TX. The tech said the orings had gone bad and the hose deteriorated. It seems very similar to this recall https://www.edmunds.com/car-news/2014-mercedes-benz-e350-recalled-for-fuel-line-problem.html I called Mercedes USA and opened CASE [XXX]. No reply yet. Fortunate the car didn’t catch on fire or someone thrower a cigarette while I was driving they downtown. Leaking fuel should not happen INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
Fuel smell really strong & a huge fuel leak started on 6/20/2022. The fuel smell was so strong inside the the car I couldn't stay in it. It started leaking before I fueled up my vehicle. Wen to the back of the car and notice a huge puddle of gas. I didn't know anything about this recall until today. I've owed the car for three years. I hope that Mercedes will fix this issue. Very dangerous.
Severe gasoline leak smell inside and outside the vehicle. Smell is so bad as to make it impossible to stand next to the vehicle without gasping for air and watering eyes. Due to a fire hazard situation, car can not be parked inside the garage as there is a gas water heater installed in the vicinity. Fuel leak in the feed system has been a known problem in Mercedes vehicles in the past. A recall was even issued on E350, 2014 model (Recall # 15V792000). However, my vehicle was excluded from the recall on account of mfg. date not matching with the recall notice. But here we are same problem showing up in the vehicle even after so called fuel leak probe was closed. Took it to the dealer for diagnosis and repair was quoted to be $2297. That's an outrageous amount of money to repair a problem which should not have happened as part of regular wear and tear and is most certainly a fire-hazard and safety issue. My wife and kids ride in this vehicle several times a day and currently I can't let them in this car due to the fear of fire. I would kindly request you to reopen the fuel leak matter with Mercedes and look into the matter while I seek a reimbursement of the repair cost from Mercedes Corporate.
When I put gas in the car beyond one quarter of a tank, I get a very strong gas smell coming from the drivers side rear fender and tire area.. There is no visible gas leak on my garage floor. The car is stationary/parked in the garage

- What is wrong
- Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2014 E350 and E350 4Matic sedans manufactured June 4, 2014, to July 9, 2014. The affected vehicles were built with a fuel feed line that has a single flare fitting instead of a double flare fitting.
- Risk
- If the fuel feed line has the incorrect flare fitting, the connection between the fuel hose and the fuel feed line might develop a leak or may completely disconnect. Leaking fuel in the presence of an ignition source increases the risk of a fire and if the fuel feed line disconnects, the vehicle would stall, increasing the risk of a crash.
- Remedy
- MBUSA will notify owners, and dealers will install the correct fuel line, free of charge. This recall began on January 11, 2016. Owners may contact Mercedes-Benz customer service at 1‑800‑367‑6372.
