This vehicle which is the x164 chassis has a rear fixed panoramic sunroof that is made out of polycarbonate. The polycarbonate sunroof glass is breaking down on the inside of the panel and is cracking. This poses a safety concern due to the fact that once it cracks and degrades to a certain point it will break. If this panel breaks while traveling down the road especially at highway speeds it can fly off the vehicle in turn hitting cars behind me causing an accident. The other safety concern is that when it breaks it more than likely would cause injury to occupants of my vehicle that would be sitting in the back of the car. I have taken this to a body shop as well as the mercedes benz dealer and they have agreed that it is cracking and is breaking down structurally speaking and that it is a matter of time before it breaks. It is not a matter of if, but when. I also have done research and found that polycarbonate should not have been installed on these vehicles due to the fact that between the heat and body flex which causes the stress cracks. This is a fact that polycarbonate panels should not be installed in any case where there will be stress. Due to the body flex these panels installed on these mercedes benz SUV's have a pretty good amount of stress and coupled with the intense uv exposure being on the top of the vehicle is causing these to break down. This is a very common problem on these SUV's but mercedes benz doesn't want to deal with it. I can't get anybody to return calls on this and mercedes has not wanted to deal with it. This should be at the top of the safety recall list for these vehicles. I can't stress enough how this is anmajor safety concern. Please address this and make mercedes recall these vehicles for this repair. Thank you!

Takata recall
This car has a oil cooler leak after our oil change at the mercedes dealer we started having an oil leak and the mercedes dealer told us it's the oil cooler leak.
The "check engine light" is on, when I took the car to the dealer, they told, " the ad blue tank is corroded." I have alway fueled with disel recommended by mercedes. How can tank get corroded so early. I suspect faulty in the manufacturing. I request you to do necessary investigation into it. I have heard similar incident about faulty ad blue tank from many others on forum: http://mbworld.org/forums/gl-class-x164/396987-2010-gl350-bluetec-fuel-system-corrosion-big-problem.html
After a long trip with the 2010 mercedes gl350 bluetec, I noticed fresh oil on the garage floor. I took the gl350 to a local mechanic for an oil change the day after, and the mechanic noted that there is significant oil under the engine. Few days after, check engine light came on, and I took the gl350 in for a check, and another mechanic confirmed that the engine oil cooler seal is broken causing the oil leak. It seems that this is a very common fault with mercedes om642 engine in my gl350.
