2013 MERCEDES-BENZ C300 Complaints

The contact owns a 2013 Mercedes-Benz C300. The contact stated that the fuel tank was leaking after refueling. The fuel had leaked out to half tank. The Fire Department was called, but no assistance was provided. The contact stated that there was a puddle of fuel in the driveway. Additionally, the passenger’s air bag warning light was illuminated. The vehicle was taken to the local dealer, where it was diagnosed that the sensor in the module needed to be replaced. The vehicle was repaired. Additionally, the dealer confirmed that the leak was coming from the filler tube entering the fuel tank. The dealer recommended replacing the fuel tank. The vehicle was not repaired. The manufacturer was contacted and confirmed that there were no recalls on the VIN. The failure mileage was approximately 90,000.

Fuel tank is leaking at connection between fill tube and tank. Multiple recalls have been issued apparently for similar problems with cars of other years. With less than 1/2 tank, the fuel leak is not as pronounced. With the tank full, the tank drips fuel. Fire department in Riverside was called and confirmed issue. Upon bringing vehicle to Clearwater Mercedes and other mechanics, the problem was confirmed. Dealership says that Mercedes Benz denies that the problem is theirs to resolve. Dealership fixed other issue that was not producing symptoms but stated that the cost to resolve was $5000.00 (about the value of the car at this point).

On several instances of breaking, my 2013 Mercedes Benz C300 pulls hard to the right and becomes very unstable. I assumed it was a brake problem by the way the car drove. I took it to my mechanic, who immediately identified the rear subframe had rusted so much that a control arm had broken loose from the subframe. The rear subframe acts as a foundation for the rear suspension and holds the backend together. Fortunately I was able to get this diagnosed prior to a serious accident. The car gets very unstable, especially at higher speeds, when braking. There are no warning lights that will catch this. This problem absolutely places both passengers and other cars on the road at risk of a collision when braking, especially on the highway at higher speeds. I am going to contact a local Mercedes Benz dealer to evaluate replacement of the damaged parts to ensure the car is safe to drive following repair. Based on the links below, it sounds like a known issue at Mercedes Benz. I was never notified of any issues or from prior service visits, or via mail notice from the manufacturer. My mechanic was shocked, to say the least. Hoping MB will take care of this dangerous problem without hassle.

The Brake lines in this car rot very early in life span. This is a severe issue as no one would know unless car is brought in for repair. There is already a extended warranty for subframe rotting for my c300 and several other models and years . Both of these should be repaired due to poor manufacturing not just the subframe. Both of these issues even independently put everyone on the road at risk of potential failure. Car has been brought in for repair and has been pointed out to me both by independent party and Mercedes Benz dealership in my area. There are NO WARNINGS also multiple claims for both rusting and rotting

The driver side indoor handle keeps breaking. I have repaired mine 4 times but still keep breaking. The connector attached to the handle is so fragile it cant withstand regular use. why hasnt this been recalled by mercedes? One repair costs 1400 dollars.

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?
