Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted. Ranges reflect the 3 tested variants for this model year.
Complaints for the 2015 Mercedes-Benz E350 are spread across a handful of systems, with no single dominant category standing out by volume. A recurring concern involves the fuel system: multiple owners describe a fuel smell inside the cabin traced to a leak at or near the electric fuel pump located beneath the rear seat area, sometimes detectable only by a technician and without any warning light. Brake-related complaints describe rear brake lines corroding and failing, in some cases resulting in a sudden loss of braking pressure with no prior warning. A few owners also report power steering malfunctions, describing the steering becoming heavy or unresponsive and a malfunction message appearing on the dashboard, again often without a preceding warning light.

With Injuries
By System
The 2015 Mercedes-Benz E350 has 5 recalls, with the most serious concerns being an unexpected airbag deployment, a potential underhood fire, and sudden loss of power steering assist, any of which can cause a crash or injury.
The driver's frontal airbag can deploy without warning while driving normally, which creates an immediate risk of injury and loss of vehicle control. The hood seal is a separate fire concern: a rubber strip along the hood can fall into the engine compartment and contact hot exhaust components, which can ignite it. On the steering side, the electric power steering control unit can lose connection at its pins, causing the system to cut out and leaving the driver with significantly heavier steering effort, particularly at low speeds or during parking maneuvers.
Two recalls involve the vehicle's electronics. A software issue in the airbag control system can cause the airbags not to deploy correctly in a crash, meaning the front occupants may not receive the cushioning they rely on when they need it most. There is also a fault in the emergency call system, where a software error causes the system to report the wrong date and time, which can result in emergency responders being sent to an incorrect location after a collision.
