Incorrect Software Calibration May Cause Fuel Pump to Remain Powered in a Collision

There is a faulty software calibration that affects several areas including shutting off the fuel supply in a collision. This could cause a fire hazard during an accident. Dealers will reprogram this software. The Mercedes-Benz recall number is 2008 070001. This recall began during August, 2008.

Wire Harness to Starter Motor May Be Damaged

The wiring harness to the starter motor may be routed incorrectly. This could lead to chafing of the protective sleeve on the engine mount cover. Over time, this chafing could wear through the sleeve and expose the underlying wiring. Damaged wires may result in a electrical short and loss of function of the vehicle's electrical system. Dealers will inspect the wiring and correct its routing. If necessary, the protective sleeve and/or wiring will be replaced. This recall is expected to begin on May 12, 2006.

Pulled this info and writing a letter: Filing an Official Consumer Complaint...

Power steering pump started leaking. Bill=$450. Never buy a mercedes without a warranty. This r350 is a "German nightmare". Mercedes has lost it's engineering glory of those days at least on this one. Be c...
