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.

My vehicle was damaged by K and H auto. The electrical unit is malfunctioning, the light is broken on the right side, and the rotors and brakes have been rusted, please have someone attend to this matter. Thanks, and have a very blessed day. Another company by the name of ans towing, towed my vehicle without care and I am now having acceleration issues with my vehicle. The vehicle was dragged through water on October 17-18, 2018.

C300 6-cyl

  • 16,300 miles
I have a Mercedes Benz C300 with 16,300 miles on it. The vehicle came with Continental, contipro, 225/45 R17 91H tires on it two tires on the left side of the car have developed bubbles on them and will have to be replaced. The tires on the right side will have to be inspected since they may have bubbles on the inside. I have just read many complains about these tires and feel they are dangerous and should be recalled.
