Mercedes-Benz ML350 Problems
Check Engine Light Due to Faulty Camshaft Adjuster Solenoid
The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.
Rough Shifting of Automatic Transmission
Vehicles equipped with a 7-speed automatic transmission may develop a rough shifting condition, most commonly going up from first to second gear and going down from third to second or second to first gear. Our technicians tell us this is due to an internal component failure. Mercedes has released updated parts; the transmission will need to be removed and disassembled to complete the necessary repairs.
Tailgate Latche may Stick Causing Battery Drain
The tailgate latch may stick causing a drain on the battery while the vehicle is parked.
Loss of Power Steering Due to Leaking Steering Rack
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.
Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

I am being quoted almost a thousand dollars for this. Is that right?
Can you tell me if this model has a timming chain or belt.
If it's belt when you must change it.
Thank you.
Two questions. I have just purchased this car two weeks ago. The check engine light came on yesterday. ARe there things I can try before taking it in for service? Also, what type of oil and how...

Why am I hearing a noise in the front left tire area that goes faster as I excelerate?
Mercedes-Benz ML350 Reviews
I have a 2007 ML350 which I purchased in 2009. I have no major mechanical complaints except that I am constantly changing lights bulbs (headlight, break lights, etc.)and the "Service B" indication keeps coming on. I've had an oil change maybe 2x a year being that I do a lot of driving but NEVER do I take it back to Mercedes, I take it to firestone or Mavis.
Wish I knew about the electrical problems, my trunk has stopped opening and closing by itself now I have to force it down and open myself.
I have a 2005 ML350 with 110k. I am now replacing the rear shocks for the 1st time. My issue with this Suv is, the A/C unit. It was replaced 2 years ago and the new one really struggles to perform. You would think "Mercedes" everything should work great. I am sorry to say, not on this Suv.
I purchased my 07 ML350 from Ray Catena in Union, Certified Pre-Owned with 16,000 miles in January of 2009. At time of purchase I was told I had "free" oil changes and 5 year factory warranty coverage. Lets just say, few months later check engine light was on, took truck to dealer, another few weeks later, service light was on and took truck back to dealer, most of the light bulbs were replaced within the first 3 months of ownership, NOTHING WAS FREE, oil change or service as I was told, in fact, it costs me about $700 each time I take for service, six months after purchase needed new tires and brakes...few months ago the heating system failed, no heat in truck when it was -0 degrees out, took back to fix, cost me $4,000. Check engine light back on, back to dealer. NOW, the entire right side of the truck HAS NO lights and I am being told is an electrical problem the truck has. For two years I have been back and forth replacing ALL bulbs in truck while it has been costing me a fortune, NOW I am told its electrical and I am out of warranty. What is going on??? NEVER again will I buy another Mercedes vehicle. Did I mention that I paid the vehicle in full (CASH/Check) at the time of purchase???
you are right about Bruce Bennett. Take your money and run. What a disgrace. Business people not. Seems like take the cash and go back to Florida is the feeling . I feel the same way you do. Something should be done!
2008 Mercedes ML 350. I'd never purchase another vehicle from Bruce Bennett Nissan in Wilton, CT. They sold me a car with worn out rotors, leaking power steering system, needed an oil chane 2 wks after purchase and camshaft bolt leaks and gave me a hard time with fixing the leaks. Never returned phone calls. What a disgrace to America.
