I was pulling away from the curb, steering wheel started making whining noises and harder to turn. I continued on city streets then to a freeway where my car began to overheat. I pulled over at a gas station opened the hood and could see fluid all over right lower driver side. It seemed to be coming from a hose by the power steering cap and the right side of the radiator. Under the car same spot right passenger side I could see power steering and radiator coolant leaking from that area.

I bought this car yesterday from an individual off craigslist and the power steering has gone out 5 times. So far only at very low speeds, but I have looked online and seen numbers complaints with power steering failure at faster speeds too. Very unsettling. There were a couple of recalls regarding the clamps and hoses, but upon research I found that Y car has no open campaigns. I guess that means they fixed the problem. There is an obvious problem still and I need it fixed or I need a new car. This is not safe.

While driving on the highway at 60mph the vehicle started shaking violently. The brakes started engaging on their own pulling the car to the left and right and nearly bringing the car to a sudden stop. It took a lot of effort to keep the vehicle from pulling into the other lanes and causing an accident. The bas/esp light came on the dash and has stayed on now. This all lasted for about 10 seconds. I was in the 3rd lane of a 4 lane highway during moderate traffic. I was almost rear ended by two different vehicles. I have been researching this issue and found many other drivers with the same thing. This is a dangerous defect and needs to be addressed. It doesn't take much for a sudden change in direction and speed to cause a severe accident when driving on the highway, and knowing that this vehicle is capable and know for doing this makes it very dangerous. It makes me wonder how many fatal accidents have occurred due to this problem, but no one knew because it was just assumed the to be driver error.

Driving home on a local street at about 30 miles per hour, approaching intersection, trying to turn, all the sudden, steering wheel became very hard to turn, with no assisting power, car run over to the other side of the road, almost crash into curb. It is very lucky, there is no incoming cars, would have crash head on otherwise. Car towed to dealer, found steering hose from radiator to steering rack broken off, steering fluid splatting all over engine. Dealer stated no recall for steering hose coming out of radiator, but there was recall on steering hose coming out of pump. So this defect was not covered. I urge NHTSA to investigate this dangerous defect immediately, and issue recall to save lives.

I have a 2002 Mercedes Benz (mb) ML320. The power steering fluid was depleting all the time from a leakage between the power steering pump and the hose. I took the vehicle to an mb dealership in georgetown, tx (garlyn shelton Mercedes Benz dealership). The repair was under recall, but the dealership still charged me $214.16. I told them the repair was for a recall, but they would not let me take my car without payment, so I paid them to have my car back. However, I'd like NHTSA to compel them or Mercedes Benz to refund me back my $214.16. I wrote to mb headquarters in New Jersey and they sill refused to refund me back my money. I have a receipt of the repair that was done on the car and the cost they billed me. I can send you the letter I wrote to mb headquarters and the repair receipt if you contact me. I'll be grateful if you can help me from this ripoff.

The contact owns a 2002 Mercedes Benz ML320. While making a turn at approximately 35 mph, the contact heard a loud noise coming from the steering column. The driver had to exert greater effort to make a left turn. There were no warning indicators illuminated on the instrument panel. On several occasions, the vehicle was taken to an independent mechanic to have the power steering fluid reservoir filled because it was extremely low. The vehicle was taken to an authorized dealer for diagnostic testing and they repaired the vehicle according to NHTSA campaign id number 03V-121. The power steering cooler hose and one clamp were replaced; however, the failure still persists. Recently, the fuel pump hose and clamps were replaced at the contact's expense. The technician recommended that the fuel pump be replaced. The VIN and mileages were unknown.

On Wednesday, September 24, 2008, while driving to work my steering wheel became difficult to turn. When I left work, I noticed that most of the steering fluid had leaked out of my vehicle. Then on Thursday, a co worker contacted me and told me that she saw a recall on the news about the steering on Mercedes SUV. I immediately contacted the local dealer and was told that they did not have a recall in their system for my auto and it would cost me $110 to have them diagnosis my vehicle. I contacted the 800# that was on the news and was told that someone will get back with me. In the meantime, I am a recent single parent with a 14 year child that I Transport in a vehicle that I having a difficult time to steer.

Numerous problems with exterior and interior lighting. Most importantly the left turn signal continually goes out without notice. Sometime the interior left turn lights up and sometimes it doesn't. other times the interior left turn light goes completely out placing me and my children in great danger. Also I made a left turn and the steering went out just as I entered the beltway and was unable steer the vehicle.

This vehicle has numerous defects, and has been in for service countless amounts of times. Mb promised to replace the vehicle if their factory representative could verify my complaints. They absolutely found numerous, redundant defects and now only want to fix the vehicle, rather that replace the vehicle. What a bunch of liars. The vehicle has issues with the steering system, the wheel rubs and the power steering fades out, the radio and cd changer malfunction constantly, fumes from the ventilation system, and when you hit a bump, the car almost goes out of control, even the esp light comes on.
