I own a Mercedes ml 320, 2001 model. The vehicle has had repeated failures since I purchased it new. The vehicle is now three years old and has 5700-0 miles on it. The most serious failures involve the fuel pump on this vehicle. The fuel pump has failed twice, with the most recent failure being 11/13/03. Large amounts of gas fumes fill the passenger compartment and a serious danger of explosion exist. The fuel pump location for this model is underneath the rear passenger seat and directly under where my children sit. Mercedes Benz has been aware of the fuel pump problems for upwards of five years and have failed to correct it or acknowledge a problem with it. No recall or notices to the consumer. In addition the ml 320 model has a long list of other emmision failiures and overall failures. The fuel pump is the main item for my complaint and is a huge safety issue that should be looked into as well as their refusal to address the issue or acknowledge it. Other failures and issues on my car include: O-2 sensor, fuel filter, premature wear and replacement of brake pads (front and back), steering problems, throttle sticking at take off (at times), window motor, drivers side. Switch as failed twice in 57K miles and reason is switch is unable to handle designed amperage. Also a potential fire hazzard. No recall or notice and a repeated know part failure for this model year and other model years, rear emmission evaporator part. Also related to gas fumes in the interior of the vehicle and common failure item. (part name is not correct terminology), battery failure within one year, battery not designed for amperage load either and common failure. Also as fire risk., numerous other failures that are not entirely safety related for this product., a serious look into this vehicle and the companies actions regarding these repeated failures of fuel related items and other items is needed and requested.
