SUSPENSION, SERVICE BRAKES
While I was driving my 2012 MB C300 4Matic Sport Sedan in Nov', 2023 with history of regular maintenance, noticed a pretty load knocking noise, shudder and drifting to left a bit when it brakes from the driver's rear side especially on the highways. I took it to our local mechanic who was horrified to report that the sub frame was broken and completely rotten out too specifically rust issue with the rear suspension-rear subframe. He gets other German Cars like BMW & Audi even older and more miles in Chicago but none have rusted so much as these MB C-Class cars. Knowing the Dealers wont accept it a manufacturing defect, he was planning to repair it (no chance of wielding that thin metal sheet as the likelihood of breaking it is high). I was surprised to see 2010 Chevy Impala having a much more robust under the cover protection and no rusting with 115k miles.

I started hearing noises about a week ago while driving. Last night while driving home in the evening traffic, I braked and car violently jerked and veered to the right almost hitting the car in the front. I took the car to a shop this morning and they found that the rear subframe had collapsed due to rust and advised the car was extremely dangerous to drive.

WHEELS, SUSPENSION, UNKNOWN OR OTHER
Rear driver side wheel was making a clicking noise leading us to believe there was an issue with the strut and/or shock. Due to the nature and severity of the noise, we took the vehicle to our mechanic ASAP. Upon inspection, mechanic identified that the sub-frame had completely rusted through which could lead to other catastrophic issues making vehicle no longer safe to drive unless repaired. Due to the age of the vehicle being 11 years old, the cost to repair was almost the value of the vehicle basically making this a complete loss. I understand that Mercedes Benz has extended the warranty to 20 years for this issue for other models identifying that it is a design/parts defect but not the C300 although I have found that this is also an issue for this model.

UNKNOWN OR OTHER
I was driving on the highway and came to a sudden stop and the car fishtailed putting our safety and the safety of others at risk. I brought my car to a mechanic and I changed my tires. When I went for a wheel alignment the mechanic found that the K bar subframe was corroded and cracked. There was no warning prior to the failure. I had no idea there was a problem because the K bar is behind the snow flap and was hidden.

STRUCTURE:BODY
Recently we had he brakes replaced and new tires put on to prepare for a trip out to Minnesota in a couple of weeks. My son felt like the car wasn’t driving correctly and took it to the shop and upon being put on the lift the service department called and said the rear subframe rusted out and was broken and the gas tank was scratched do to the subframe rubbing against it. When he called Mercedes they told him there was an extended warranty put on these cars which I never received a letter concerning this issue. *The car is waiting to be towed to Mercedes, they would not give us back the keys, it was too dangerous to drive. *my son unknowing drove this car on the highway putting himself and others in danger for who knows how long. If he did not take it in for a check before driving himself and his father to Minnesota they could have been killed. Perhaps a fire due to the gas tank damage. *confirmed by independent repair shop but will be seen when the car is towed to Mercedes. *there was no warning to the dangerous situation my family was placed in. The cars should have been recalled. We were told by Mercedes they were fixing the problem as it arises, luckily no one was injured or killed when this problem arose!
