Ac/heater smells like mold/musty/mildew inside the cabin. Took for the extended warranty but will not honor unless you have proof of cabin filters purchased every year. This is their way of finding a loop of not fixing the issue.
My panoramic sunroof has an extreme amount wind coming through it while driving 40 miles per hour. I can also hear my panoramic sunroof sliding back and forth. I-??m terrified that that it will fly off while driving and cause a road hazard.
In the past few months while driving this car in the Washington DC metro area at normal road speed, the car has suddenly and unexpectedly lost driver power. Each time, I have pushed down on the gas pedal, and after some hesitation the car has moved forward, and then continued to operate normally. This has happened three times in the past 3-4 months.

Check engine light comes up. The crankcase ventilation has to be replaced. This is a well known defect in design by Mercedes Benz and there are hundreds of people who have had to replaced the crank case costing thousands of dollar to only have it happen again due to its faulty design. It-??s well documented all over the Internet.
The code P052E reads at only 49.000 miles....Mercedes wants $3000 to repait ir (replace PCV valve ). Car runs and drives normally....its probably a faulty sensor. I have seen a lot of posts with owners havins same issue.
The small plastic located inside the sliding panoramic sunroof explode and the Panasonic sunroof can be open/close or up/down normally but when I hit close it will stop where the broken pieces was and the roof will automatically move back to the fully open position Dealer said need the rail replaced -2057800175 -2057800275 Motor is broken, need to be replaced, he said after saying the roof can go forward and backward, up and down but can-??t close completely. I was gullible to believe what the technician and sale guy said. Technically technician can check the voltage and say it for sure if it is broken. Also, a technician already knew that the sliding rail is damaged. He jumped to the conclusion that motor is broken because of sunburn. I have asked my nephew what he would do in this situation. He innocently said he would replace new sliding rails first and try to run if the -??alleged motor -?? is really broken. If it is broken, he can just switch to a new motor before testing to confirm it working. He wouldn-??t decide to buy a new motor that cost $1,400 extra while the old one might be working properly. Anyway, labor with rails and -??motor-?? cost $3500. Then later I learn I-??m not alone. How many affected from this defective parts that Mercedes doesn-??t sell it separately. Owner must buy 2 set of rails- a left set and a right set. Cost $1100 total. So since the number of affected are pretty high, a few factory in China and turkey decides to produce these little and sell it online for $15-92, glue and lubricants included. -number of owners struggling to find parts https://mbworld.org/forums/c-class-w205/734208-pano-roof-failure-2.html Parts that Mercedes cannot sell it separately so owners have to buy 2 sets left set and right set rails. -??Try words like repair sunroof kit for Mercedes -?? on eBay only a few couple thousand people buying it in 2022 alone. https://www.ebay.com/p/28019877104 Motor broken? https://c.xtime.com/tvyUiiMwuwoA2L8JXX#/completePage
I bought my 2016 merecedes Benz c 300 4 matic with an engine light on. I took it the dealership and is the positive crankshaft failed. The crankshaft could reduce power on car. At 73000 mile the crankshaft should have not failed.
the Burl wood trim panel on the interior doors are deteriorating, the drivers side panel is deteriorating to the point that it looks like acid is eating away at the material there is red markings showing.. i find this could be a safety hazard as it could eat away at the door itself. i have pictures of evidence. there was a recall on Mercedes E class during the same years i purchased my car, my car is the C-class which was not part of the recall, but falls into the same category as time frame of purchase. Mercedes told me to contact you. i look forward to your response as this is a safety concern thank you
I took my 2016 Benz through a car wash and realized the glass in front of my sunroof that is part of windshield is loose. I can hear wind coming through when I drive. This is driving hazard.
I bought my 2016 merecedes benz c300 4 matic with the engine light on.when I did a diagnostic on it came back to a po52e is bad. It had 73000 on it when I bought. Now I sit at 77000 miles with the bad part.
The check engine light came on. I pulled the code and it was P052E, and requires the replacement of the crankcase ventilation system. I am told that this happens on virtually all C300s and (and maybe the GLC300 also). I think this should be recalled.
