16V899000 2016-12-14

Steering:electric power assist system

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2013-2015 SL550, 2013-2014 SL63 AMG, 2014-2016 E350, 2014 E350 Cabriolet, E350 Coupe, 2014-2015 S550, 2015 E350 Bluetec, 2015-2016 E400, 2016 E550 Coupe, and Maybach S600 vehicles manufactured August 23, 2012, to August 14, 2015. The affected vehicles use an electric power steering system that may have improperly soldered contacts inside the control unit, potentially resulting in the power steering system deactivating while driving.

If the control unit pins lose connection, there would be a loss of electric power steering assist, increasing the risk of a crash. The increase in pin contact resistance can also increase the risk of a fire, even while the vehicle is parked and ignition is off.

15V792000 2015-11-24

Fuel system, gasoline:delivery

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.

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.

The affected vehicles have a rubber seal at the back of the engine bay that may temporarily stick to the hood when it is opened and then may fall into the engine

If the rubber seal falls into the engine compartment, it may contact parts of the exhaust system, increasing the risk of a fire.

Power train mileage not reported 7.7 yr in service

Mercedes Benz had a previous recall Campaign # 2009100001 which affected vehicles until 2012 and mine is a 2014 model E350. It has the same issue with Engine severely misfiring and jerky on the road as if it is going to STOP IN THE MIDDLE OF FREEWAY while driving and cause a SAFETY RISK for my family and others on the road. Specific component is Oil leaks from transmission wiring harness and ECM connector. The leak is from camshaft hall sensors and transmission drain plug. Mercedes Benz dealer in Pleasanton, CA has confirmed the issue after I paid $218 for diagnosis.

Suspension mileage not reported 8.6 yr in service

I want to report a structural issue with the Mercedes rear subframe rusting. Three Mercedes dealers told me that it is common but there is no recall. The mechanic told me that if this is not corrected the back wheel will fall off while you are driving. There are no warning lamps. Please help.

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
