2002 Mercedes-Benz ML500 Problems
The power steering return hose may leak at the radiator cooler fitting. If the clamp is not properly tightened, the hose can blow off, causing increased steering effort and a mess under the hood.
Electrical switches in the door latches can fail, causing the door locks to rapidly actuate up and down multiple times when the locks are activated by either the keyless remote or door lock switch. A new door latch will need to be installed.

It is not uncommon for the power steering rack to develop a fluid leak requiring replacement of the rack assembly. Loss of power steering fluid may also cause an abnormal noise and damage to the power steering pump.
The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern. A recall on certain 2002 models have been recalled for a related issue - for more information please click here»

RepairPal Expert Overview:
It has been determined that, under certain circumstances, use of the brake pedal may not disengage the cruise control as expected. All other means of disengaging the cruise control should remain effective. If the driver were to "pump" the brake pedal instead of applying consistent force, the level of force necessary to disengage the cruise control may be unusually high. Dealers will perform the repairs necessary to correct this concern. The recall is expected to begin September of 2011.

2002 Mercedes-Benz ML500 Reviews
I truly enjoy driving this car. It's quite powerful, compared to the Volvo S80 I previously owned. The only things I can complain about are the breaks which make a hell lot of a noise. I tried cleaning them and replacing the pads. It did not help. I even smoothed out the discs (which you're not really supposed to do because they are composite discs) and still no help. Sometimes they screech a lot and sometimes they don't. Another thing is that the suspension is really stiff so if you enjoy driving a Chevy or a Cadillac you may not like this one. You hear and feel every pothole and uneven pavement. Other than those two things the car runs and drives great. It's 9 years old (2002 means it was produced in 2001) but I love it and can't think of buying anything else.
I purchased this car new after owning a 1998 ML320 which was very reliable. The only problems with the 2002 ML500 was that the initial wheel alignment was not accurate, causing premature tire wear. The brake pads also needed replacement at 20K miles. These two items were not covered by factory warranty. I use the 10k maintenance schedule for all inspections and fluid changes. It never requires additional engine oil between inspections. I get 17 MPG in town when the speed limits are obeyed. I also get 22 MPG on the highway at conventional highway speeds. I use regular grade gasoline all the time, with no problems. It is a powerful, smooth performer and has more than 82k miles at this point in time. However my warranty has finally expired. My service manager at Schumacher European does a superb of analyzing and correcting all problems, warranty changes and recalls, which have been few.
