Carrier/rack Problems of Mercedes Benz C300

I'm the owner of a 2009 mercedes-benz C300 4matic sport, which was purchased in 2012 from a mercedes dealer. The vehicle currently has about 60,400 miles. It was taken to a local mechanic for inspection and after hearing some clunking noises, especially when braking or turning, they discovered rust, corrosion, and cracking to the rear subframe. Upon further research, it has been discovered that this is a known problem, especially for this year and model of mercedes. There are many other owners posting complaints online about the same problem. The rear subframe corrosion is estimated to cost about $3-4k to repair. The local mb dealer revealed they are actually repairing a car with this same problem, as we speak. Another call to mb for part pricing indicated this is a common, known problem. The car does not pass inspection and has become a huge safety issue. With so many known cases and obvious safety concerns, mb should resolve this defect and place it under recall. Many owners may not even know they have this problem. Driving a vehicle in this condition could potentially cause injury or fatality to the driver, passengers, and others on the road. I've been advised to request a goodwill repair, since there is no recall. I was told by mb that I need to schedule an appointment for an official diagnosis and repair estimate at my local mb dealer ($179) before I can move forward with the request for the goodwill repair. Many other owners have received denials to their requests, which is very disappointing. Mb should be found at fault for this defect and keep the safety of their consumers as their top priority. It will likely take a week or two before I receive a determination for my goodwill request, but I'm contacting NHTSA to file an official vehicle safety complaint in hopes that the recall process is started and an order is placed to the manufacturer to issue a recall.

My windshield cracked the 2nd day I had the vehicle. " sept 2017". I have informed the mb mechanic several times and he did nothing after many failed attempts with mercedes of el cajon I asked to be placed with a new service advisor. Recieved my new windshield in Feb 2018 already having problems. Little cracks are starting to form again. Not happy with my purchase. Definitly not happy with this dealership.

Windshield quality does not meet my expectation. My windshield cracked within a couple months by a piece of rock on the road while driving on freeway.

I was driving 580-e and merging onto I-5 s when I hit a humongous pot hole with my left font tire causing it to immediately blow out. That in-turn caused my stability tracking to engage, which caused me to slow down drastically. That caused another vehicle to near miss ramming me in the back and me side swiping another vehicle. I was driving approximately 70 mph and almost lost control of the vehicle and had to immediately pull over to a very narrow shoulder of the road with my emergency flashers blinking. To ensure the safety of the vehicle, my self and other passengers in the car, I had to drive approximately 0. 5 miles to the next exit (67) to safely get my vehicle off the road to a safe location. I then called a tow truck to tow my vehicle back to santa rosa where I live to get the tire replaced and front bump repaired. I am unsure of the cause of the unsafe condition of the highway or what caused the pot hole. There were several cars stranded with damages to their vehicles as well. One person came to the same exit (food mart on patterson road) with a blown out tire as well. I have her contact information if you need to contact her.

Knocking noise when turning the wheel. Was told it could be a cracked drivershaft. Googled and see that therer are numerous complaint on this model. Mercedes should be putting out a recall.

The information system in my car gave me the symbols for the right back lights. I stopped to check and realized my lights were out. I opened the wiring in the trunk and realized that the brown wire on the outer side burned through the connector and the lamp carrier.
