1 Other Fuel System Pump problem

Failure Date: 04/25/2014

This is a follow-up to complaint #10579528. Spoke to robin, customer service representative at Mercedes Benz corporate headquarters in the united states. They refuse to acknowledge a design flaw in the rear signal actuator module as the basis for the fuel delivery failing while driving the car. The explanation they offered is that the likely cause of the failure in fuel delivery to the engine, while driving, is the fuel pump, mercedes part# 203 470 3794. However, they further explained that the only way to replace a faulty fuel pump is to replace the entire fuel tank, fuel delivery unit, fuel sending unit and wiring harness . . . The entire fuel storage tank and fuel delivery system! no one I know has ever heard of a situation where an entire fuel system has to be replaced because of a failed in-tank fuel pump. This points to yet another design flaw for which Mercedes Benz, the automobile manufacturer,hold itself accountable. What possible engineering reason can they offer other than the fact that the fuel and electrical fuel delivery components system were seriously flawed from the beginning of production?.

2 Other Fuel System Pump problem

Failure Date: 06/24/2013

I called mbusa 2 weeks ago regarding my 2002 c320 wagon which was smelling of pure gasoline which the odor was so strong it was coming into the house from the garage giving us headaches. I checked online with mbusa club members and found out this could be a dangerous situation and to call it in. I called mbusa and was told there were no recalls or bulletins pertaining to this issue and we were out of warranty to contact the dealer. I called the dealer who seemed very familiar with this issue and just for parts it was over $800 and they were not aware of any warranty, recall issues. This is our family car we use this wagon to travel daily with the kids or other little family members so we did not want to take any chances. We called our independent Mercedes Benz certified mechanic and he knew what is was just from our conversation. He had us bring it in right away and he lifted up the rear seat where our children sit and showed my husband and myself a pool of gasoline coming from the fuel pump sitting right under the seat!! I was disgusted to know that mbusa dismissed this so quickly and could have potentially put our children at risk. Please note this vehicle has been well taken care had an extended warranty and has visited the mb dealer more times than any car should ever need. This seems to be a common problem even the parts department at the dealer told us they see alot of these needing replaced and although mb has updated the faulty part they have not notified owners of the possible safety issue.
