The Mercedes-Benz E350 has only been in production since 2005 and has no reported recalls as of 2010. Carcomplaints.com has reported a National Highway Traffic Safety Association investigation into a steering wheel air-bag defect. Other problems have arisen with this E350 Mercedes according to Repairpal.com.
The Mercedes E350 has problems with premature tire wear, causing the tread to wear irregularly on the front tires. This tire wear is due to the front thrust link bearings cracking and leaking oil. These bearings are fluid filled and when they crack they create unusual vibration in the suspension. The unusual vibration in the front suspension causes the tires to wear prematurely. Oil will begin to leak out onto the pavement when these bearings crack. Once this leaking begins, the E350 owner needs to have the Mercedes taken back into the dealership and have them replaced before major problems are created.
The crankshaft position sensor is an electrical device that records the rotations of the crankshaft. Repairpal.com reports that the Mercedes E350 has a problem with the crankshaft position sensor failing in the automobile. This sensor is used by the E350 to control ignition and injector timing, which assists the Mercedes in fuel efficiency. When this sensor fail the Mercedes begins to stall and idle roughly. The only correction for this problem is to have the dealership replace the crankshaft position sensor.
The Mercedes-Benz E350 has a problem with the airmatic pump motor failing, according to Repairpal.com. The relays have been sticking, causing the pump to run at all times, even when the E350 is turned off. This causes the battery to run down and burns out the airmatic pump motor. The airmatic pump is used to stabilize the shocks on the Mercedes to provide a smoother ride of the E350. Reports also show that the airmatic pump mounting bushings have been wearing out, creating noise under the front of the car when driving over rough roads.
