SUSPENSION
Excessive rust has caused a separation of the lower control arm from the rear sub frame. From Google searches this appears to be a common safety defect in the manufacturing of these vehicles. Control arm separation causes drive ability and stability issues that can lead to loss of control of said vehicle leading to accidents that can cause serious bodily injuries including death. Why hasn't Mercedes been forced to recall the affected vehicles in the United States as they have been in several other countries?

FUEL/PROPULSION SYSTEM
I recently received a notification from Mercedes-Benz concerning a safety defect in my vehicle, and to be honest, it's really concerning. The issue is with the fuel pump impeller in certain models, including mine. If this part malfunctions, it can cause the vehicle to suddenly lose power, potentially leading to accidents. Imagine driving on a highway and suddenly losing all drive power! The scariest part is that there's no immediate solution. They've informed me that the remedy isn't available yet and that they will contact me when it is. This has left me feeling unsafe every time I turn on the ignition. I'm sharing this because we might all be using our cars for trips or outings, and I believe it's crucial for everyone to be aware of the situation. I don't feel safe driving this care very time risking my life, and more over paying for damaged car Best regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER
Over the weekend my vehicle driver side interior door handle became inoperable not allowing me to open my door from the inside. The handle flaps back & forth with no connect to the inside of door panel not making be able to get out of my vehicle. I was stuck & had to climb over to passenger side to get out. It only opens from outside . It has been functioning well for the life of me owning the vehicle, never giving me any problem until now, suddenly with no warning that it was breaking. My Mercedes dealer said I need a whole door panel & they have had several calls from other C300 owners where this handle broke also recently. So they are aware & admitted so. This is a recall or factory defect in my eyes. Also I looked online & this is very common because of a plastic not metal part Mercedes uses . Is this not unsafe enough to be recalled? It’s a no brainer! Not bein able to exit your vehicle at all. I was so scared and shocked a car of this class has this safety issue and they do not do a thing to their owners to fix it, its on owner and their pockets. This should be taken care of immediately for free. Are they waiting for someone to have an accident and lose their life to act on replacing this problem?! Again I feel this is a major safety recall that needs to be addressed ASAP. Safety, peace of mind, accessibility to exit/enter your vehicle. If no one can help you from the outside, you have to climb out from passenger side or thru the back of the vehicle. You can open your window too, but what if that jams electrically ….you are stuck. $900 plus labor should not be on me but should be in Mercedes hands to value my life & others lives more than any price as a standard part of their fleet of cars they have driving across USA. High end luxury car w/a faulty door handle that leaves you unable to get out, unbelievable ! Has safety hazard written all over it. I have a video & submitted a pic of my issue. This is my second MB I owned and I never had this danger occur.

MB 2015 C300 4MATIC. Check engine light came on. Went to a Mercedes Mechanic and they read the code as PO52E71. Crankcase Vent Valve Malfunction. This was reset and two days later the check engine light came on again with the same error/fault code being read. This seems to be a common issue for this manufacturer and is a very expensive repair. In the even this is a common issue, I wanted to report this for the record.

SUSPENSION, STRUCTURE:BODY, UNKNOWN OR OTHER
2011 C300 4matic Sport I'm very concerned about the front subframe after going over the invoice and everything that was replaced on the rear subframe due to a recall Mercedes issued. But wait doesn't the whole subframe have severe rust corrosion all throughout yes it does per mechanic/technician. I'm having steering issues while driving the vehicle when applying the breaks the vehicle pulls very hard to the left the whole car swerves to the left very dangerously. After getting it checked out the mechanic/ technician pointed out that the control arm snapped from the Front subframe due to severe corrosion. I'm not understanding how the recall was only for the rear subframe only. The whole entire subframe is severely rusted. Front subframe which may experience premature wear of the front axel carrier and a fracture risk, potentially resulting in sudden loss of steering control. After internal endurance testing determined the front axle carrier supplied for certain Mercedes SUV’s and cars may weaken prematurely. An investigation revealed the root cause of the problem was due to a manufacturing defect in which the parts did not receive proper corrosion protection. My front subframe did not receive the proper corrosion protection. It's available for inspection. It's currently still at the dealership due to being unsafe to drive. I'm having steering issues while driving the vehicle when applying the breaks the vehicle pulls very hard to the left the whole car swerves to the left very dangerously. The problem has been reproduced or confirmed by a dealer or independent service center. The vehicle or component has Not been inspected by the manufacturer, police, insurance representatives. Only Dealer and independent service center did the inspection. No warning indicators no other symptoms, this issue took place around February - March of 2023. When I received the letter about the subframe recall I was excited thinking the issue would be fixed. But No it's unsafe
