Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I have black Mercedes C230 kompressor sports sedan 2004 model. Car was purchased brand new at Mercedes authorized dealer. There is no modification made to this car and all the servicing done at Mercedes authorized dealer since I bought this car. It had only 58000 miles. Last B servicing which checked any safety related issues and includes regular maintenance, was done at authorized dealer on 02/18/2012. No issue was informed on 02/18/2012 to us by Mercedes authorized dealer servicing department. On 06/21/2012, when I was driving this car from work to home, I turned on A/C, A/C shutdown and I started smelling smoke. On left side of my car there is A/C vent and I saw fire inside the hood through that vent.I pulled over car right away and electricity went out with in 1 min of my pulling over and within 4 min, whole car was burning. My car is now totaled. This poses following security concerns: 1. Mercedes C230 2004 is made of highly inflammable material and driver and users of car has very less chance to survive if there is fire. 2. Mercedes C230 2004 model A/C unit is not of highest quality and electrical system is faulty. Both of above issues poses very serious security risks to public and it needs through investigation. I contacted Mercedes head quarter for investigation and Mercedes declined to investigate. Geico stated in report that hood is stuck and cause of fire is unknown. Geico insurance company authorized Mercedes engineers to investigate further upon my request and Mercedes usa does not want to investigate further. I have pictures of burnt car and can share if it helps in investigation to rule out above 2 concerns. We do not want others to go through same ordeal as we went through.

This car is a money pit! I bought 2004 C230 kompressor used in 2007. To date I have spent well over $8500 in repairs and the car is sitting in my driveway with its latest affliction..a completely blown engine. It is a useless piece of junk and I am out the $25,000 I originally paid for it, plus the additional $8500 I have put into it. This is how Mercedes Benz takes care of business? something has drastically changed. My dad has had 2 Mercedes over the last 30 years...they ran perfectly until he sold them. He just bought a brand new S-series (2012) and it has already been in the shop numerous times. The cars are made cheap and everything in the interior is plastic, not wood as it should be. Mercedes, you should be ashamed of how far you have let your standards fall, it is a disgrace.
