The sam box (electrical system fuze panel) located under the hood is in a spot where if the lid isn't on correctly water will drain from the windshield right into the sam box and cause the vehicles electrical system to deploy the steering wheel airbag. That's at least what happened to me. It was raining out that day and I guess I went over a bump that caused the lid of the sam to get out of place. I drove home and the car seat for a few hours. I went out upon unlocking the door as soon as I pulled the handle to open the driver side door the steering wheel airbag blew and the vehicle is now in srs mode. The dealership had told me that it's a design flaw but wants me to pay for the diagnostic. No lights were on and I did not file a police report.

the rear subframe on my car rotted out. Before they called a recall/extended warranty,I paid to have it fixed. Since it is a 2011, I was not about to pay $7,000-$9,000 to get a new one. I made the best decision with the information I had at the time. It broke in June of 2022. I had the car fixed with a used subframe from Atlantic Auto. Once I realized there was FINALLY a recall/Extended warranty, I submitted All necessary paperwork and have been denied. I wrote to Mercedes Benz Corporate office. They contacted the Warwick store. Went back and forth All summer and they have refused to reimburse me the &2,299. that I spent to fix the car. It says the decision is made on a case by case review. They have denied my claim. I have all the correspondence between myself and Mercedes Benz.

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.

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

I have a 2011 Mercedes C300 that I purchased as a Certified Vehicle - this car was purchased at The Mercedes Dealer in Kansas City. I believe I purchased it around 2013 - I have recently found out that the rear sub frame is completely rusted out. I have had the car repaired at my auto shop - Not a MB dealership, as there was not a dealership that was able to see the car in any reasonable amount of time and the car was not safe to drive. The only way I found out about this rusted out subframe was due to the control arm breaking off - This car was very dangerous to drive and in essence, it is probably a good thing that the control arm broke as this could have resulted in a loss of steering on the vehicle and a very dangerous accident! I have been reading online and speaking with MULTIPLE people who have had the same situation with this rear subframe. This is CLEARLY an issue with MB and clearly an issue that they have been made aware of. When I called the NMB service department they were a month out to just look at the car - and the part is on back order I was told - which CLEARLY indicates a lot of these rear sub frames are being replaced. I am attaching various articles / forums online that I just, at a glance, composed a list of. There are a TON of stories of these sub frames rusting out for various models. Seems to be tied mostly to the C300 vehicles. I am attaching pictures of this rusted out subframe and an invoice that I paid to have the car repaired for this issue. The ironic thing is when I was at this auto shop, there was another C300 sitting out front that had just had the same rusted out subframe replaced. Mercedes has a recall in Canada for this SAME issue and other countries have acknowledged this is a major safety issue. A rear subframe should not rust out and leave the driver with no way to steer the car. Mercedes has refused to acknowledge this is an issue in the US.

I have a 2011 C300 Sport that I purchased end of the lease (3yr.). The car was never driven in the winter for 4 seasons and most recently just the last 3 winters. Complete frame rot on the rear driver's side. Rot was noticed by my mechanic at the last oil change. He said he is replacing three rear frames for customers as soon as he can get parts. Parts are limited and only in Germany. I want it repaired with genuine parts. If the frame separates while the vehicle is at highway speeds, operator control can be compromised. The brake line which attaches to the frame has ruptured in many cases from what I have read. I called MB customer service and there is no recall at this time. I called the local dealer and they have been replacing quite a few frames with the same issue. This is a dangerous failure and if I remeber correctly about 8-10 years ago Toyota recalled trucks and SUVs for frame replacement.
