2004 Mercedes Benz Ml500. Vehicle was serviced / repaired by zembrick mercedes in adison wisconsin on Feb 3 2011. The repairs / service included replacing a seal on the power steering pump. Within days of the repair the power steering unit leaked all it's fluid from a hose clamp. Found the recall 08v465000 for this problem which per the recall covered all 1998-2004 mb ml's . However, the dealership and mbusa states this recall is VIN specific and this vehicle is not covered under this recall. The problem is obviously still present and ongoing, however mbusa seems to be applying this recall to suit their interpretation. The problem has not been fixed and the hazards originally identified has not been addressed and corrected.

6 Power Steering Fluid problem of the 2002 Mercedes Benz ML500

Failure Date: 04/02/2008

In March of 2003 mercedes initiated a recall for my vehicle for a problem with the power steering hose, the car was taken in for servicing and the problem supposedly fixed. On April 2nd of 2008 I took the car to mercedes because it was making a really loud sound I was told that the power steering hose was leaking a $665 fix. I had the work done. On April 15th of 2008 the check engine light came on took the car back to mercedes and was told the power steering pump needed to be replaced a $1211 fix. I was furious at this point. In September of 2008 the NHTSA issued a recall on the model for a problem with the clamp for the power steering hose. I contacted mercedes when I became aware of this recall earlier this week. I was told that the hose that was replaced on my car's power steering system is not the one being recalled. I do not qualify for the recall because my car's VIN number was not a part of the specific cars that were recalled even though it was included in the 2003 recall. I argued that my power steering pump went bad because of mercedes negligence with the hose issue and I have gotten nowhere with them. The dealer will not help me and mb USA will not help me because my VIN is not on that recall even though I am still having the issue and yes my car is still leaking fluid all over my garage.

7 Power Steering Fluid problem of the 2002 Mercedes Benz ML500

Failure Date: 11/01/2007

This car was purchased in sacramento CA in Aug of 06, at this time we also purchased an extended 2 year warranty which we understood to be expiring in Aug of 08. The car worked fine with no issues until sept of 07. I started the car at 4 am to head to work and it make a really loud noise, it got worse when I turned the steering wheel. I contacted the mb dealer and was told to bring the car into the dealership. I expressed concern about not wanting to drive the car making that sound, he assured me that it was fine. I brought the car into the dealership and was told it just needed power steering fluid so they will top it off for me at no charge and it will be fine. Took my car and left. Two months later on nov1st, same issue, took the car in again, was told we will just top it off for you at no charge, took my car and left again. On Nov 15th I had my car transferred to atlanta by moving truck since I was moving but did not want to put the mileage on it. Took it to mb for its regular servicing 1 week later no problems were found at that time. "" on Apr 5th 08 the noise came back, I took the car to the dealership and was told we would just top it off for you but we noticed that there are some leaks so you may want to bring it in to get that checked out. I did this 2 days later and was told it was the power steering hose an $800 fix that was not covered by my warranty. I had the work done. On Apr 20th my check engine light came on, I went back to the dealership had to pay again for the diagnostic to be done, even though one was supposedly done 2 weeks prior. Now it was the power steering pump at a $1400 fix. I was pissed. How did they miss this 2 weeks prior? how did I even know it was the hose at first and not the pump? how was this found conveniently after my warranty is no good when the noise was there before? a complimentary diagnostic was done by the service mgr on Aug 29th and now I am being asked to pay $2100 for fix the problems found. The warranty should be honored.
