The German automaker Mercedes-Benz announced last week that it will be voluntarily conducting a medium-scale recall of some of its E-Class station wagons over issues with the rear air-suspension system.
Mercedes recall impacts nearly 4,000 vehicles
According to the National Highway Traffic Safety Administration, the automaker will be calling back 3,613 of its E350 4matic station wagons from the model years 2007 to 2009.
The affected vehicles were all manufactured between July 1, 2006 and April 30, 2009, said Mercedes-Benz.
Air suspension issues
The vehicles are equipped with self-leveling air-powered rear suspension, that adjusts suspension depending upon the vehicle’s load. A possible problem with that suspension system may have occurred during assembly, says the National Highway Traffic Safety Administration. The problem could cause the connecting rod in the rear suspension to fail, resulting in reduced control, and possibly leading to an accident.

Specifically, Mercedes-Benz says that improper materials were used when putting together the suspension system. This failing may cause the ball head on the level control system’s connection rod to seize up. When that occurs, because of a relay error, the system will continuously pump air into the bellows. In time, the increased pressure will lead to the bellows’ failure.
Past crashes unknown
No information was released on the National Highway Traffic Safety Administration’s recall summary saying whether or not the problem has caused any known crashes or injuries in the past.
The automaker says that the improper materials were used on all the vehicles targeted in the recall. The maintenance personnel at its certified dealerships will replace the level control connecting rods in every recalled E350 4matic station wagon, free of charge to the owner.
The recall is expected to begin some time in August. The affected owners will receive a notification in the mail.
Mercedes-Benz owners who think their vehicle may be affected can call the automaker at 201-573-0350. The National Highway Traffic Safety Administration can also be contacted on its recall hotline at 888-327-4236.
Mercedes-Benz E-Class vehicles are luxury models that are made in a variety of body and engine types. The E designation originally stood for Einspritzmotor, which is the German expression for fuel-injection. Fuel injected gasoline engines, though developed in the 1920s, first appeared in factory vehicles in the 1950s. Today, most Mercedes-Benz models are built with fuel-injection, whether designated with the prefix “E” or not.
