The rear subframe rusted and broke

- Charlotte, NC, USA

Rear sub frame is corroded as shown to me by the Mercedes mechanic in a video he sent me.The car is available for inspection. I am nervous to drive now after hearing about the related problems others are having such as braking issues and swaying when the brakes are applied. The way I found out about the rear sub frame corrosion was when I needed work done at the dealer. This problem should not be happening to all of these vehicles. In other countries, Germany and Canada, to name a couple, Mercedes dealers are fixing this through a recall. Why not the US? The date below is when the mechanic told me about the problem and that it would cost $8000. to $10,000 to repair

The rear subframe rusted out. This seems to be common for this vehicle. Mercedes should replace for free. It-??s recalled in other countries.

After parking my car, turned ignition off, did some work for 45 minutes I came back attempting to start the car. The car won-??t start, I am not hearing any of the normal sound that usually takes place when I place the key in ignition. Message on dashboard telling me to remove the key. Car will not start. After checking battery and calling mechanic they tell me the my steering wheel lock is bad. The ESL went bad out of nowhere. Car won-??t start, steering wheel is locked and the only way to fix it is to take it Mercedes-?? dealer and pay over $2000. I search on google and found out that this is a common issue with my 2010 C300. This is a manufacturing defect and Mercedes should recall it and pay for repair. In my case I parked my car in my garage, imagine if I was traveling on highway way and the steering wheel locks or failed on the side of busy interstate hwy. the worst part is that Mercedes dealer did nothing t warn me when I bought the car about this issue especially since it is know since 2008, and they will not allow after market parts to be installed by other mechanics. So this is defective and Mercedes should be forced to recall and replace for free. We should not wait for someone to die before this is fixed. This happened without any warning PLEASE FORCE MERCEDES TO RECALL AND FIX THE ESL NOW.

Cam solenoid most C300 will stop turning on all the car does is ask U to take key of ignition.. I searched the issue and there is thousands of people having the same issue. It's not fair to consumers not to have a recall on a part that is defective that cost over a thousand to fix. Please help us resolve this matter

Notices of recall; scheduled with dealer and never received a call back to replacement. The call smells strongly of burnt plastic since I bought the car. Every single car maintenance person tells me the car emits that smell.

Takata recall. After purchasing my 2010 Mercedes C-300 I've noticed a gas smell from the rear passenger side but this has gotten worse after I park my car in my garage overnight. The entire garage and vehicle interior smell like gas. I then notice a gas leakage spot from the rear passenger side tire. This happens when I have full tank or half of the tank full of gas. I red about this online I called the dealership but I was told the recall/ extension tank warranty does not apply to my car. Concerning the seat-belt the rear passenger side seat belt is default. It does not buckle

I got Mercedes Benz C300 2010 in less than 6 months, the vehicle developed power steering lock issue; the vehicle will not start and got me stranded in a parking lot of a grocery store. I researched the problem online and realized several individuals have had similar issue. I brought the issue to mbusa, they did not deny its a common issue but said based on the history of the vehicle I am not eligible for any relieve on the cost of repair. I feel it is unfair that I will have to pay for something I believe its a manufacturer default. Now I am compelled to pay $1,700 for the repairs.

After I turn the car off, the front left light on the top continues to stay on. If I move the knob back and forth slightly, then shuts off, at least for a while. I just had to deal with a dead battery yesterday when I was getting ready to leave work. From what I have recently researched, this is a common issue among this model. Has a recall been made for this" will this cause any other issues with the vehicle? if it is a shortage in the electrical, am I in danger of the vehicle not reacting appropriately while driving at night or at a higher speed on the highway? is there any risk of it catching fire? there is also a sensor that needs to be replaced. I am not that car savvy, but I believe it may have something to do with fuel injection or something filtering properly. Is that another common issue"
