2004 Mercedes-Benz ML350 Problems

Suspension & Steering -- Verified

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.

Miscellaneous -- Verified

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. The affected door latch should be replaced to correct this concern.

Engine -- Verified

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Miscellaneous -- Verified

The covering for the center console can bubble and discolor. Replacement of the affected part is most commonly only way to repair this concern.

Suspension & Steering -- Verified

A problem with the ball joints can cause a creaking noise. There is an updated part to remedy this problem.

2004 Mercedes-Benz ML350 Reviews

Mercedes dealership unable to diagnosis check engine light (code associated with fuel line). Replaced gas cap after nothing was found on a "smoke test." No defect codes are found. Recently replaced purge valve, but light is back on and dealership advises to replace "charcoal cannister." If that doesn't work and still no defect code, then something with gas tank is their final suggestion. All this with the only symptom being the check engine light (runs fine) and no actual diagnosis.

I don't know what other vehicle you can drive in Texas for 36,000 miles without a water pump, and I don't encourage ANYONE to try it, but I can verify it's been done. About 55 miles each way, twice a day.

And before that, I broke the radiator on a beach. 20 or so miles, without damage then and it was about 95 degrees on that day.

One last thing...people complain about dealer maintenance, and schedule A's and B's are expensive. But if you add it up, you can go 10k to 12k miles between Mobile 1 0-40 oil changes. So that it costs me 10 oil changes at ~150 per equals about 1500 per 100k miles. If you add up the 40/per for each oil change at 3,000 miles, you pay MORE for that maintenance than you do in a Mercedes?! (Note: this includes A service but not B service; that costs more but they check and replace almost everything.)

Again, I don't know a car built six years ago that you can drive for 230k miles without multiple repairs. I'm shooting for 500k miles.

I really like the steering on this vehicle... makes good turns vs. other SUV's I've driven. Mine now has 80,000 miles on it and just replaced a headlight at an independent garage - only $14 ! I'm sure the Mercedes dealer would have charged far more. Probably need a new water pump very soon... but other than that, I've had no problems at all with this vehicle. I enjoy the smooth ride, too.

When you think Mercedes, you think luxury and reliability (generally speaking). However, I have not had any of this with this car. At 54,000 miles, I have had 3 brake jobs (rotors replaced TWICE!), of course the front rims get dirty within a day or two of driving (design flaw), drivers seat replaced due problem with seat heating (hot spots), motor for rear seat heating and a/c had to be replaced, when changing where I wanted the heat or a/c to come out (vent, defrost or at feet) the dial would not work. I could not change. A broken arm had to be replaced. The smooth ride that I had when I purchased the vehicle has become extremely rough. When I brought it to my dealership (Globe Mercedes in Farifield N.J.) they stated that the ride was normal and that they found nothing wrong. I brought it back to them 2 weeks later telling them that they must be mistaken because I KNOW there is a big difference in the ride. I took a test drive with one of the technicians and he said to me "It does seem pretty rough". However, when I came back the to pick up the vehicle, my service manager( Bill Waggoner) said the ride was normal and that nothing could be done. Both cigarette lighters don't work (have hardly used them at all) and it's not the fuse. Had a small leak in the coolant compartment and now a power steering issue (which is the reason I am on this site).

Overall nice car, I like the handling.
