WHEELS
I drive 40-50 miles per day in this vehicle. I noticed a wobble develop last week, so I stopped into a local service shop to see if maybe a tire weight fell off. They brought me into the garage and spun all four tires individually in front of me...Every one of them was no longer a circle, more oval shaped. All four rims lost their shape. I drive this car on a highway to work every day with occasional potholes and rough concrete connections, but nothing notable over the last 11k miles I have put on the car in 8 months of ownership. The wheel repair shop who rolled them back in to shape told me "Mercedes-Benz and BMW are our most frequent customers" either for dents, cracks, or curb rash. He even went on to say "AMG rims may be the softest on the road. Even a speed bump going a little too fast will destroy an AMG rim." Sure enough, another C43 AMG was parked next to me in the parking lot when I picked my car up and a 2011-2013 C250 with the AMG sport styling package had just parked. I think seeing three AMG products in for the same reason is more than a coincidence. Furthermore, all four wheels to have lost their shape at only 33k miles total on the car is also hard to believe. After further research, it seems many Mercedes-Benz, especially AMG, drivers are facing similar problems; C43 with 5 cracked rims over 2 years, C43 with 1 rim replaced after 1 month of ownership, C43 with all new wheels after owner discovered 3 cracked rims out of the 4. Many stories. Given the violent wobble at highway speeds, it is scary to think that potholes could render these cars undrivable. These cars are advertised with performance in mind, yet rims that crumble under normal driving conditions, such as my 22 mile drive to work every day. Marketing speed and hardcore driving is reckless for cars prone to develop oval shaped wheels under these conditions. Specifically, the 19" AMG sport rims like the package on my car. No warning lights or anything either.

POWER TRAIN
I have owned the vehicle for only about 4 months. My wife took the car out for a short errand and returned to tell me that the engine light was on. I took the vehicle to AutoZone and had the code ran on their diagnostic computer and it returned a P052E code for “Positve Crankcase Ventilation Regulation Valve Performance”. I have done a lot of research and have learned that this is a common problem and incurs huge financial impact to unsuspecting buyers. Mercedes has even made improvements to the part because of this issue. It’s not safe due to the possibility of oxygen build occurring in the combustion chamber. This part should be recalled and repaired by Mercedes.

Interior driver door handle not operating. I brought the car to the mechanic and he states this is a common problem and the whole door panel has to be replace for 1000.00. I went home and researched repairs on this and this is a very common issue with mercedes and many mechanics including the one I went to doesn't understand why this is not a recall. This a very serious safety issue. I have to lower the window to get out of my car. If I have to get out quickly it is impossible. If the window stops working I cannot get out of the car. This safety issue affects me and my passengers if I have to get out of my car quick such an accident or fire. The quality is so poor on these plastic parts of the handle and removing the door panel is complicated because it not meant to be removed and taken apart. I am a nurse that was traveling in Nevada when this occurred.

I was driving our Mercedes Benz C300 and noticed the braking distance taking longer than normal. Also, the rear end responding differently than normal. We took our Mercedes C300 to Mercedes Benz Dealer to be serviced. The technician looked under the car and found the rear subframe rotted out. The service advisor informed us of this being a known defect. We have to be cautious about driving the car until it's repaired due to the fact of being a serious safety issue. MB needs to recall these vehicles and repair them before someone is seriously injured in an accident. Many drivers are uware their subframe has rotted out. I've taken this car to the same MB shop for 8 years and all in a sudden this comes out of nowhere.

Our garage housed C250 4d SDN year 2013 had its service B performed 12-5-22 and revealed rust on Chassis. Was informed that this has been seen frequently on cars of this genre. Was told deterioration could result in chassis breaking and causing an accident. A recall for this issue occurred in Europe...why not here?

ENGINE
Most M274 engines have P06DA00 fault code internally. Harness for oil pressure regulating solenoid valve is short/open inside the engine oil pan. It can cause excessive oil pressure and premature oil pump failure. As the broken wire is sunken in the engine oil, I worry if it can cause fire. If the oil pump fair during driving prematurely, engine can be stalled. Mercedes-Benz knew the issue but they decided to ignore it.

The vehicle is not near any water. This a known problem with this model Mercedes. Spoke with Mercedes Benz USA, was advised not to drive the car, the frame could detach and puncture gas tank!! I have seen the recall for the problem in Canada and Europe and the repairs were covered by Mercedes. Now I have my only mode of transpiration, undriveable and sitting waiting on help!!

WHEELS
This is actually the second time I met the issue within the four years I own the car. After some researches, I decide to file this complain so some 3rd party can investigate into it. I have a Mercedes AMG C63s 2019 version with 19 inch OEM wheel. Firstly, it was a low tire pressure light. The dealership confirmed the tire was fine and there was actually a crack on the inner portion of the wheel that was causing the tire to leak air. I did not remember hitting a pothole or anything, and the tire showed no signs of damage so the wheels must be defective. But the dealership did not recognize it and would charge $1500/wheel to replace it. Please investigate into the Mercerdes AMG C-class OEM wheel rim as I also saw tons of people complaining this issue in a MB forum. The tricky part is that when another driver argued with the dealership that if they were not responsible for the wheel crack, he would take the wheel for a full evaluation. Then the dealership was willing to replace the wheel for free for the driver. Please investigate into this issue as wheel crack is serious safety issue.

AIR BAGS
I received a notice several years ago for the airbag to be replaced due to a recall. Mercedes-Benz has not been able to remedy this issue for years. I have called for several years, but the Mercedes dealer near me continues to state that the airbag part is not available. I called Mercedes hotline (877-496-3691) a month ago to report the issue. No one answered so I left a voicemail. I received no contact from them. I called last week 3 times in a row and finally someone answered. I opened a claim with them for the escalation team. They said I would receive a response in 48 hours. I received no response.
