ENGINE, FUEL/PROPULSION SYSTEM
I bought this car new in 2013. I maintained it at the dealer as per MB recommendations. Last service was in August 2023. Currently had 42K miles on it. Two weeks ago 2 unknown to me lights came on and I took it to the dealer. The diagnosis was total failure due to oil leaking into the computer system. Second problem was water in the subfloor affecting sensors. Coons Mercedes in Catonsville, MD has all records. I was told that the oil leak was not detected because it was internal and due to an engine design. I was informed that there are many others stuck with this problem. I was informed that I was driving a car that could become suddenly uncontrollable. This was very scary. I was told I needed a new car. My insurance company inspected it and determined it was a total loss. I complained to MB headquarters and HQ in Stuttgart. I told them that they need to buy a new car for me. I have not heard from them. If MB know that there is an engine flaw why are they putting peoples' lives at risk?

SERVICE BRAKES, ELECTRICAL SYSTEM, POWER TRAIN
The ESP®, or Electronic Stability Control system can put the car into limp mode unexpectedly. Say you are driving on route 66 going 50 mph. The ESP system can turn off if a wheel speed sensor or yaw sensor is on the way out. This causes the car to suddenly dramatically brake and limit speed to 5 mph on the highway. Risk of high speed rear end collision and mortality to the driver.

STEERING, ELECTRICAL SYSTEM
Mercedes has had an issue with the steering lock for years and continue to not fix the issue. My vehicle would not turn on at random times, and this is due to a fault with the steering lock and key. The worst part of the issue, it’s only solved by Mercedes due to security issues and costs $2000. I was locked out of my car for hours, missing a doctors appointment, and if this was during a snow storm or heavy freeze (I live in CO), this is a potential fatal flaw. I also learned they cannot fix my vehicle for months due to high demand and coming from Germany. Looking online this is a continued problem for over a decade of vehicles and this needs to be resolved either by recall, a price adjustment due to this being a Mercedes flaw, or give the capability to certified maintenance locations to do the job for a fraction of the price (I see the price of the part is marginal compared to the upcharge by the dealer.

SUSPENSION
Excessive rust has caused a separation of the lower control arm from the rear sub frame. From Google searches this appears to be a common safety defect in the manufacturing of these vehicles. Control arm separation causes drive ability and stability issues that can lead to loss of control of said vehicle leading to accidents that can cause serious bodily injuries including death. Why hasn't Mercedes been forced to recall the affected vehicles in the United States as they have been in several other countries?

SUSPENSION
Rear subframe rust through, affecting the function of control arm. When braking mildly caused the forward motion of vehicle to swerve into oncoming traffic. It has been reported and is in their possession. There was a small clicking noise like a possible loose shock absorber, a few times in the past month. Then two days ago, the sound became stronger including a clicking noise like two pieces of sheet metal torn passing each other. Upon personal inspection I found severe rust through on the subframe on the left side in front of the left drivers side rear tire. Corporate has sent a letter extending the warranty for that part. Photos can be provided.

ELECTRICAL SYSTEM, STEERING
I purchased the vehicle in 2015, and a few months ago I started having issues with the steering wheel, as well as an error message with the airbag. More recently, I am experiencing issues with my ignition switch, and after doing some research I’m seeing that many people who drive the mage and model of my vehicle are experiencing issues with their ignition switch suddenly going out. I’ve been quoted 2k to repair the issues, but I feel the Mercedes should be responsible for taking care of what seems to be a faughty ignition switch with this particular model. There was no warning, no indication that there was a problem, one day my car just wouldn’t start. I need to report this to make sure buyers are aware with issues with the C300 model for all vehicles that are a 2013 and under.
