Two problems related to power steering fluid have been reported for the 2005 Mercedes Benz ML350. The most recently reported issues are listed below.
The 2005 ml 350 I believe is experiencing the same problems that led to recalls for ml series in 2003, 2004 and possibly other years. The power steering system looses fluid caused by leaks in the plumbing of the power steering pump. The only sign of an initial problem was the noise made by the pump because of loss of fluid. This vehicle requires special fluid which is not commonly available. Loss of steering control is the result of the loss of fluid.
Bought the 2005 Ml350 used last summer (2010). In the first few weeks of owning the vehicle while slowing down or stopped, the acceleration seemed to drop low enough to make the vehicle stall. No check engine light on, but took it back to the dealership and they couldn't figure out what was wrong. Since then, it has happened multiple times over the year. Also, while starting the vehicle it will stall and I will have to keep retrying to start it and press the acceleration pedal to get it to finally start. (only use the recommended octane suggestions from the mercedes booklet, and follow all directions during fueling) finally, seems to possibly have a steering fluid leak. (only use mercedes power steering fluid from dealership).
