This car has been in for repair at least once per month since I have had it. (16 months)
When I got it, the remote door locks did not work.
The CD changer skipped. It took several attempts to fix it. The radio/stereo power amplifier made noise and had to be replaced. The radio/GPS system died and had to be replaced.
Several pieces of interior trim fell off, the glove box door fell off. Can you believe it on a $55K vehicle.
Both headlight bulbs have been replaced twice.
The electronics module which controls the alarm, internal lights and trip computer died three times. The dealer gave up trying to get a couple of trip computer functions to operate.
The brakes wore out at 20K miles. The wear indicator light did not indicate a problem and the disks were scored. They had to be replaced at my expense.
The plastic trim elements between the side windows and the rear hatch cracked.
The rear hatch lock jammed and does not lock. I only discovered this by accident recently.
I like to drive with the rear seats down and the rear windows open. The dogs like this configuration. Unfortunately, over 30 miles/hr, the ML's interior resonates and sounds like a base organ pipe. I am sure the volume will cause ear damage.
I understand that these vehicles are manufactured in the USA rather than Germany, which (no disrespect) may explain the poor build quality. But regardless of where it's made, I cannot believe such a costly vehicle can be that poorly executed. I've never owned a Mercedes, and reading reviews like this one put me off the idea entirely! good luck mate.
Can you tell type of usage of the vehicle? I don't believe things just break without too much stress.
Can you clarify where are M series made?. because they are relatively cheaper than the sedans.
The Mercedes M-class is made in Alabama, USA.

I have an ML 430 with 90,000 miles. If I open the driver side windows while in the freeway, the sound is unbearable. This is not aerodynamic build. Unlike my 450 SL, even if the windows are open in the freeway, the noise is minimal.
When the "Check Engine" started to light, I brought the car to the shop that specializes on European cars, and I paid $611 for the parts and labor. Half-way home (40 mile drive), the "Check Engine" is lighting again. The gas mileage is terrible. I bought one to pull my 19 footer boat and because it is a 4-wheel drive, it has more power and traction. I did not anticipate these kind of features though. Made in Alabama? Had I knew that I wouldn't have bought one.
