I took my car for service "B" at the dealership. They told me the rear subframe is rusting and there is a hole forming already. Apparently, this is a known problem that Mercedes Benz provided warranty extension up to 20 years with unlimited mileage. However, they stopped at 2015 models. Mine was bought from the same dealership in October 2015, but it is a 2016 model, but actually has the exact same problem earlier models have and they cover with their voluntary extended warranty. I am told to replace it, it will cost at least $4600. They are refusing to cover it under warranty because I my car is at around 60,000. The car did not even reach 100K and well maintained, but has rusted frame already that can be a serious safety hazard according to Mercedes Benz associate.
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
Panoramic Sunroof deterioration, which caused the sunroof to get stuck due to fragments in the sliding area. Sunroof unstable. Unable to ride with it open and makes a whistling sound when closed.

Vin tool confirms parts not available.
Front glass panel on panorama roof detached while driving on freeway on a straight segment and flew off. I it appears that there is a problem with adhesion that is used to secure and there are a number of Mercedes models with panorama roofs of various years all having the same problem. It cost over $2000 in dealer repair and replacements.
Glass piece in front of sunroof of panorama roof flew detached and flew off while driving. I was driving on freeway about 80 miles per hour on a straight stretch. It was not hit by anything. Just the wind. Cost to repair $2178 at mb authorized dealer.
On Oct 14th at night car was driven in heavy rain off interstate I5 off ramp to exit interstate. There were cars both in front and behind us exiting and upon driving further noticed there was standing water. Other cars were making it through slowly, there was no room to turn around. This car almost made it to the end of the offramp and then stallled. Other cars were forced to go around. Tried to restart the car to no avail. Called for roadside assistance. Noticed smoke coming from the hood and then all lighting went dark in car. Then saw flames from the hood. Quickly ran through water to escape and flames got several feet high. Passer by's had called 911 as entire front of car was engulfed in flames. Fire department had to cut open car hood to put out fire. Car damaged beyond repair and they too were incredulous that a new car would be engulfed in flames after stalling in the rain.
After stopping and waiting at a traffic light for 15-30 seconds, I had my feet on the brakes and left turn indicator on. The "hold" option to lock my brakes was not engaged. The car was stationary. Without warning, the car shifted into drive and jolted forward into the vehicle ahead of me at the light. (I was the second car in line, and I stopped about a half car length behind the other driver.) the acceleration was not a typical, gradual movement associated with what happens when I release my foot from the brake to drive. It was a sudden and jarring jump regardless of the fact that my foot never left the brake. I tried to press the brakes multiple times to stop the forward movement, but my car hit the vehicle in front of me twice. The steel bumper of the other vehicle was not damaged. The front area of my hood (emblem and grill) were crushed. I reported earlier electronic issues to my local dealership as notable oddities, but none made me this concerned about safety of others, my passengers, and myself. As recently as a week earlier, my rear-view camera froze and locked as I was reversing into my garage, so had I trusted the screen in my car, I would have reversed another 5-10 feet into my garage. I could not unfreeze it without putting the car back into drive and restarting my car. Months earlier, the sensor on my side mirrors started to go off without any other source of danger or collision on vacant streets. The air pressure alert warned that my tires were becoming dangerously flat; however, en route to the gas station, the pressure monitor noted that all tires were now returning to normal pressure levels and no inflation was needed. There have been many peculiar events with this new C300 in recent months, but my primary concern as a caregiver is the sudden acceleration from a stopped position--or from any position--without my direction or intent.
