FUEL/PROPULSION SYSTEM
Filled up gas and strong gas smell can be smelt throughout the car and Check engine light came on, took car to auto zone for report. Stated emissions code was listed. Was told to replace gas cap and code should clear. Replaced gas cap, still had code. Took car to shop and was told this model has this issue with this specific year and newer, and the problem could be one of 3 things. Replace gas cap, did that, replace fuel pump closing cover, did that, replace purge valve canister, did that. Check engine light still comes on and strong gas smell still exist after each fill up. Mechanic told me reach out because there was a recall on this same model a few years back...

ELECTRICAL SYSTEM, EXTERIOR LIGHTING, SUSPENSION
My husband drove my car home from work on April 18th 2022 and it was a bad rain storm that everyone. He had to drive through a couple of big rain storms. Soon afterwards he got around the corner from the house and the electric system failed lights started going off everywhere in the car, he lost steering and couldn’t see and almost crashed and got the car home safely but it wouldn’t shut off so he had to disconnect the battery for the car to shut off. On April 22 nd the car was towed to the dealership because it wasn’t driveable and they check out the car and discovered water under the carpeting of the drivers seat near the wiring of the car. I submitted an insurance claim and an adjuster went out to see the damage and his thought is that it’s due to a known problem for this car that’s been reported by many people with this same vehicle. The Mercedes Benz c300- 2010-2014 years. I checked online and apparently many people have reported this same issue water underneath the car due to bad firewall manufacturered not sealed correctly which could be a manufacturers/ safety issue. My husband was almost killed thank goodness he made it home safe that night. I believe there are many people that have had this issue and someone needs to be done for safety purposes, and I believe the insurance doesn’t want to cover the repairs because they are blaming Mercedes’ Benz. My cars been in the shop a month and I still have no answer from State Farm or the shop Mercedes Benz.

STRUCTURE:BODY
I brought my car into the dealer to have my annual state required inspection, and was told by the dealer that the rear subframe had severe rot and corrosion, to an extent that they would not allow the car to pass inspection as it was hazardous to drive, and if the subframe cracked, for instance, by driving over a bump or pothole, I would endanger myself, passengers, and other cars on the road. I was stunned to find out that my Mercedes, a premium automobile, by a marquee manufacturer, which has a reputation for engineering/manufacturing excellence and had such significant corrosion. I was equally stunned because I have consistently maintained my car and done all the recommended maintenance. I asked the dealer service manager to hoist the car on a lift so I could inspect and verify the corrosion on the subframe. While I saw the significant corrosion on the subframe, all other parts of the underside of the car were in excellent shape and drive-able condition. This leads me to believe that there is a design/manufacturing flaw in the subframe. I researched this issue online and discovered that this exact Mercedes subframe has been recalled in other countries, but not in the U.S. It is a known and dangerous defect, Mercedes clearly knows it's a dangerous defect, and yet they have not recalled it. This has put me, my family, passengers and potentially other drivers at risk of serious harm and injury had the subframe broke while being driven. Additionally, it unfairly shifts the burden of repair onto the consumer rather than Mercedes for fixing a known and dangerous defect. Does a tragedy need to occur before this defective part is recalled? I hope not.

STRUCTURE:BODY
The rear sub-frame of my car has almost rusted in half. While driving on 95 I had to brake rather quickly and it felt as if the whole car was twisting. I called my mechanic the next day, drove in and put it on the lift only to find out that the sub-frame was almost detached from the car. Had this happened at 70 MPH it could have been disastrous. Mercedes knows about the design flaw but refuses to take any action.

Driver side subframe broke in half due to rust. However, vehicle has low mileage and was very well maintained and is in mint condition throughout with no signs of rust anywhere underneath on any parts. This subframe rusted through from the inside and with no way of being able to see or catch any warning signs for owners.

ELECTRICAL SYSTEM, STEERING, UNKNOWN OR OTHER
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.

ELECTRICAL SYSTEM
During maintenance of vehicle, completely bare wires were discovered. While researching replacement options, I became aware that this is a known issue ignored by the manufacturer and that no cost effective solution exists. This is a car my son has recently purchased on his own and I am assisting in the maintenance of this "German Engineering Turd" You would have thought they learned a lesson on arrogance from the past.

Rear subframe failure due to corrosion. Car has approximately 130k miles. Based on internet reasearch, this is a common issue with the c300 w204 Mercedes’ car. It’s a serious safety issue and warrants a recall before someone is killed. Failures have happened for this car at various miles on the odometer, without warning.
