I was quoted $3,500 to $4,000 by the Mercedes Benz dealer to install a factory tow hitch on to a ML 350 Bluetech 2011! I was wondering if anyone else had this happen and if so, where did you go to have the work done and were you happy with it? I live in Southern Cal.

I got my hitch installed at Uhaul and I just want everyone to beware. I have a brand new 2015 ML350, after they installed the hitch I've had a constant rattle under the vehicle. I had another Uhaul location take a look at it and they state that the heat shield was trimmed and the way that they trimmed it they cannot repair it. I filed a claim with RepWest, their insurance company, and my claim was denied. Now, I've been trying to get a hold of the location that installed the hitch and have not received a call back after a couple attempts.

Avoid the headache. It's just been one issue after another with Uhaul. Hind sight is 20/20, definitely a lesson learned. Now just trying to figure out how to fix my new car. So frustrating and upsetting.

Not sure which version of the tow hitch did you use, but generally speaking for all of them (including the original MB one), it is required to cut a part of the heat shield out.
Rule of thumb, with your MB product - make sure you know the skills of the mechanic/technician working on your car. That also applies to the typically simplest maintenance. Someone earning a minimum wage at these discount tire shops: nationaltire/uhauls/etc. is not qualified to touch anything more complicated than toyota camry, and even with simplified cars they seem to struggle. For instance, someone pulling a pollen filter out of your car can damage several other parts if you don't have the right tools and you don't particularly care...
