Power steering hose assembly leakage
The hose clamp used to secure the power steering fluid cooling hose to the steering fluid cooler may not provide sufficient clamping force for the connection.the loss of power steering fluid may result in gradual reduction in power steering assist (I.e., increased steering effort) over time, with potential damage to the power steering pump. There have also been a few incidents of hose separation from the fitting, that have resulted in more rapid reductions of power steering.testing conducted by mercedes-benz indicates that the leaked fluid is not likely to be exposed to hot engine components.there are no known allegations that the defect condition has caused a vehicle fire. Mercedes-benz will conduct a voluntary recall campaign for the subject m-class vehicles.mercedes-benz will install a new hose clamp on the power steering hose to the power steering cooler of the subject vehicles.during clamp replacement, the power steering cooling hose will be inspected and replaced as necessary.

Continuing problems with power steering. Taken to the dealer for inquiry over 3 years ago; no resolution presented. Problems have persisted and gotten progressively worse. Only when researching, was I made aware of the recall. No notification from manufacture or dealer. Substantial costs incurred and vehicle continues to leak after numerous repairs. Moonroof unable to close 100% - taken to dealership. Advised the problem was seen routinely with this particular moonroof. Advised to fore-go repair due to cost. Upon extensive research, this problem is quite customary and unsure as to why the vehicle was not recalled or repairs made by the manufacturer. Would like a written response outlining options and resources to remedy these issues.

Power steering failure - driving this lemon of an SUV, car started to pull and was difficult to steer. Thank god, I was not on a freeway and could pull over without killing someone.
Reference: vehicle complaint - 47046 in september 1999, we purchased a new mercedes-benz, ml-320. In 2003, the vehicle was part of a recall concerning a lower power steering hose and clamp at the radiator fitting. On august 7, 2007, while driving the vehicle, the lower power steering hose blew off losing all hydraulic fluid. We lost the power steering and had extreme difficulty steering the vehicle. The same problem has occurred with a family member's ml-320. In addition, the transmission has frozen four times in first gear. The mercedes dealer was unable to locate the problem. The vehicle was towed to the dealer, and they replaced the hose; however, we have not retrieved the vehicle from the dealer because we are fearful about driving the vehicle due to these recurring problems.
