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 2 tested variants for this model year.
For the 2011 Mercedes-Benz E350, the dominant complaint pattern by a wide margin centers on the airbag system, which accounts for roughly half of all filed complaints, owners frequently report unexpected warning lights, airbag non-deployment concerns, and issues with the passenger seat occupant sensor failing to correctly detect a seated adult. The second notable cluster involves the structure and fuel/propulsion systems together, where owners describe rear subframe corrosion serious enough to cause structural failure, along with brake lines rusting through at the plastic support clips. Several owners report that subframe replacement was performed under an extended warranty, but that corroded brake lines were left unaddressed at the same service visit, only to fail shortly after. The brake line rust pattern appears concentrated in vehicles operated in regions with road salt exposure, with owners describing complete fluid loss after the lines corroded through.

With Injuries
By System
The 2011 Mercedes-Benz E350 has 5 recalls, all involving the frontal airbags: the most serious concern is that both the driver and passenger airbag inflators can rupture and send metal fragments into the cabin, causing serious injury or death.
The inflator rupture risk spans multiple recalls tied to the Takata airbag defect, which has been subject to ongoing repair campaigns. For vehicles that have already had the passenger airbag serviced, there is an additional concern: an incorrect replacement airbag may have been installed during a prior repair, meaning the bag may not deploy properly in a crash. All five recalls on this vehicle involve the frontal airbag system.
