SERVICE BRAKES, SUSPENSION
On my recent visit to my trusted independent service center, which specializes in Mercedes-Benz, they noticed serious corrosion problems. There were no symptoms to alert me to any problem. Also, I never received the notice from MB so how would I know? My mechanic asked me to sign a waiver (which I never have had to do before) that stated the rear subframe was rotted completely through; needs to be replaced ASAP; and is unsafe to drive. The rear brakes lines also had corrosion. This tells me the car is unsafe to drive, and must be fixed. It seems that MB issued an "extended warranty" to cover the rear subframe, but not the rear brake lines. I contacted MB Corporate who said they 'may' offer some assistance. I have an appointment next week with a MB dealer who must provide an estimate of the damage and cost to MB for their approval before doing any work. As a result of learning what's eating my car underneath, I won't take it on any extended trips. I really am afraid of something bad happening. And it has, to many others. No one should ever have to get into a car and worry about these two safety issues. It’s very important that Mercedes-Benz recognizes its responsibility to not only its customers, but to all the other drivers on the road who can be negatively affected through accidents caused by these corrosion issues.

UNKNOWN OR OTHER
Wood trim throughout the car is cracking and falling off the car on the dash board as well as the doors and the rear side panels. The trim pieces that remain on the car are very sharp and jagged and are a significant risk for cuts in day to day use. In the event of an accident a passenger could be seriously injured from this jagged wood . My car is a 2011 E550 convertible, the W207 platform, the very same car in 4 door form the W212 platform, from model year 2010-2016 is fully covered for wood replacement as NHTSA has deemed it a safety issue. I have been told by Mercedes Benz corporate there is no coverage for my car, they suggested I report this safety issue to NHTSA in the hopes of having this safety issue addressed as quickly as possible. I respectfully request help in getting the issue with the wood in my car covered under the same safety consideration. Thank you.

ENGINE, ELECTRICAL SYSTEM
My 2014 Mercedes started getting a fault light with multiple performance issues. Mercedes dealer where I can carry out my routine maintenance diagnosed the issue to the electrical harness being contaminated with engine oil and it needed to be replaced on the engine because of a known issue whereby oil from the upper camshaft sensors seep into the harness and makes its way to ECU and causes possible failure of the engine control, which could lead to shutting down or worse, incorrect engine timing which would lead to incorrect detonation at the compressors and subsequently engine failure at critical operational phase. This below link and attached document describes the issue well. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, FUEL/PROPULSION SYSTEM
I purchased an E450 Mercedes before reaching my first service appointment while driving my two daughters home from school the car began to shake uncontrollably, lost power, and then the engine light and oil lights came on. The car was towed to the manufacturer dealership for repair. It was determined that the piston number four was broken and the engine needed to be completely replaced. Less than two months after having the entire engine replaced the car broke down again with a similar shaking. This time one of my children and their friend were in the vehicle with me. The car was towed back to the dealership where they said the fuel pump went out and needed to be replaced. When I arrived to pick up the car, the technician pulling the car around noticed the shaking and the engine light on again. I did not leave in the car. The dealer kept the car to further investigate why the engine light was on again. Two days later they called to say they’d been driving the car around to “air it out” as air must have been trapped in the fuel system and that nothing further needed to be done. I am not confident that this vehicle is safe to drive or properly repaired. I’m also not confident that this vehicle doesn’t have other unknown issues that will arise overtime. It’s unsafe to drive children in this car. I still have not even reached 10,000 miles on this car.
