2002 mercedes-benz Ml320. Consumer is having some warranty repair problems with mercedes-benz. He also states that mercedes-benz is refusing to pay for any recall repairs. The consumer stated noises and lack of power from the vehicle were reported to the dealer. An independent repair shop found dirty solid metal residue in the transmission fluid, there were missing parts in the planetary gear. The cause of damage was faulty assembly of the pins/plugs in the gears, which resulted in the parts becoming loose and breaking the teeth, which caused excessive noise and loss of power, ultimately the transmission was replaced. The power steering was leaking, the brake and engine lights illuminated several times, the catalytic converter was replaced, the door locks had to be repaired, the battery was replaced and the sway bar link bushing were replaced as well.

While driving at highway speeds power steering failed. No impact reported.

Consumer complained about power steering problems which made the vehicle hard to maneuver.

(1)vehicle was making a left hand turn and became almost impossible to turn steering wheel. (2) crankshaft dampener became separated at point of rubber vulcanized and caused serpentine belt to come loose leaving power steering to stop working along with all other pulleys run by the same belt. (3) dampener and belt were replaced. (old parts are available) this is an extremely dangerous situation that my local dealership says is happening very frequently. New types of replacement dampeners have been changed six (6) times in the last five (5) years in the parts book. Several local mechanics say it's a very common problem and they wonder why a recall has not been ordered. It would be very easy to find out how many crankshaft dampeners have been ordered and replaced by both dealers and parts sales. Again, let me say this is a very dangerous situation that is very common. My primary worry is that a small person would not be able to turn the steering wheel if the power steering goes out as in these broken dampener cases. I'm a 225 lb man and I could barely bring the car to a safe stop at only 25 miles per hour. What would have happened on a mountain road? please investigate this problem for everyone's safety. Thank you!!.

Fuel gauge does not read correctly/run out of fuel/engine quits loss of control, power brakes and steering may lead to crash/defect.

The power steering on the Ml320 does not always respond to abrupt changes of direction in low speed maneuvers. On numerous occasions, I have steered to the left or right at low speed (<10mph) and then quickly tried to steer in the opposite direction. The power steering requires a great deal of force to change the initial steer direction and it is extremely difficult to change direction. This could easily result in an accident. I don't believe this behaviour is unique to my particular vehicle but is instead a common trait of all mls.

The power assist failed while driving 65 mph. The condition caused difficulty in steering while pulling off the road and the vehicle hit side barrier. The dealer was not notified.

The harmonic balancer on my 1999 mercedes Ml320 engine type m112 failed and resulted in $4,000 to repair. The part failed with no advanced warning. Even the mercedes dealership who performed the power steering recall two weeks prior to the failure did not spot any problem and they knew to be looking. I was lucky the failure occurred in my driveway backing out of the garage in stead of on the freeway with an immediate loss of power steering or destruction of the engine.

We believe that one or more mechanical and/or design failures contributed to an accident in which our 2001 Mercedes Benz ml 320 was involved.

My power steering went out after making a slow, 180 degree turn when exiting a car wash--I was turning into the street when I noticed it. I was told the vehicle had been recalled to replace the power steering part. I never received a recall notice (that I can remember) and I have had the car in for service and this was not pointed out. The situation could have cause an accident if there had been traffic coming in either lane. I had three kids in the car with me.

Lost power steering while driving. Was told by mercedes on-call service technician that the clamp to the power steering is coming loose in all of the ml 320's and the car still isn't being recalled. In fact there were two other complaints in the one hour he was there helping me.

This is the second time that the power steering fluid has leaked causing sudden loss of steering control. First time (Feb 2002) the dealer termed it as fault of "clamp" and now the second time (March 2003) the dealer is terming it as problem with "power fluid hose" first time the incident could have been fatal as happened while car in motion at 60 miles / hour on freeway. Luckily being Sunday morning there was low traffic and managed to pull it to side. Second time could have caused significant property damages as car was being pulled out of garage and could have hit the car parked next. In both cases there were no prior indication for failure.

The power steering failed upon starting the vehicle. Fuel leaked and made it difficult for the driver to control the vehicle.

The clamp on the power steering hose came off and caused the fluid to leak. As a result the steering wheel locked up. The dealer was notified and the vehicle was repaired.

Vehicle lost power steering at 40 mph, dealer determined ac fuse had blown. Dealer replaced wiring harness and hose. Ts.

Mercedes benz, Ml320,1999, harmonic balancer failure. Destroys the whole bottom front of the engine including making power steering inoperative. May cause a real bad accident. I also have a 2000 c280 with 47,500 miles which looks like carries the exact same problem with the same possible accident potential.

I heard a snap sound while driving and a burning rubber smell afterwards. We were going to pull into a parking lot to investigate,but half way to making a left turn, we lost all steering capabilities and coasted to the side of a intersection. I normally drive on the freeway, and if this happened then, I am sure I would have had a major accident.
