SUNROOF SLIDE AND SHOE REPAIR. SLIDES HAVE MELTED DUE TO HIGH TEMPERTURES OWNER OPERATIOR DID NOT CAUSE ISSUE. Opened sunroof and sunroof would not closed. Discovered melted slides inside to sunroof tracks. It was a Rainy day and could not get sunroof to closed. Would have interfered with the visibility to drive due to water getting inside vehicle. Cost to repair is extremely high for this repair and when contacting repair shops they are seeing a large number of Mercedes with the same problem.

My boyfriend and I were driving my 2015 MB C400 down the road in November 2020 and it was a beautiful day out so we decided we would open the sunroof to get some fresh air. I was driving so my boyfriend pressed the button for the sunroof to open. As the sunroof was opening, there was a cracking and popping sound coming from above us. We immediately pulled over at a gas station to see what was happening. Upon getting out of the car and looking closer at the sunroof, we noticed many cheap plastic components that were just broken and crumbled laying inside the sunroof tract. We removed the broken pieces and then tried to close the sunroof several times. T Each time, the sunroof went into the closed position BUT immediately went straight back to the popped up position and would not completely close again. I took my car to the MB dealership in Athens, Ga where they told me it would be almost $2500 to repair which I did not feel as if I should be held responsible for as I had just purchased the car in January 2020 only 11 months earlier. I was in fear that the sunroof would detach from the car and cause serious injury to any motorist behind me. I also have a [XXX] son who is now scared to ride in my car!! After doing much research on this issue, I have found that this is truly a common problem with this MB model. I have reached out to the corporate office a few times and they only tell me that there is no active recalls with my cars VIN. It is completely unacceptable that MB is fully aware of this issue yet they continue to disregard the potential harm to other motorists. Please help!!!

Crankcase ventilation valve. PCV valve has failed causing check engine light. Very common issue on this model according to my research. The dealer does not have this product in stock to facilitate a repair and no support to find the part. Very difficult when trying to pass an emissions test and this is the last thing holding that back.

FUEL/PROPULSION SYSTEM
I got my oil changed last week and not my car has the check engine light on and is throwing the code p025e. From what I’ve read this is common problem in these cars. It’s an environmental hazard, because when this happens the car is not dispelling the fumes as it should and cannot be ventilated correctly.
