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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Mercedes C240 stalls immediately after prolonged turnpike travel ( 1.5 hours) at exit ramp to an arterial roadway. This increases rearend accident potential. Mercedes checked vehicle but no report codes indicated. Suggested that it may be computer of sensor related. Mercedes suggested pulling over for 30 min. To let computer reset. First incident 12/17/08 second incident 12/28/08.

: the contact stated that while driving at 55 mph, there were exhaust fumes entering the cab of the vehicle from an unknown area. The fumes caused the contact to develop headaches. The vehicle was taken to a service dealer, where the dealer was unable to determine the problem.

I am the owner of a C-230 4 door sedan VIN#[xxx]. I have an issue that I was looking into addressing when another major issue just arose that I need help from the manufacturer who I have contacted but not received a response. 1) last week I decided to quote insurance and make a change to allstate. Once they put in the VIN# major issues came. The price was way different then what I was paying with Mercury. To make this short, after talking to my broker at Mercury, it turns out my 4 door has the VIN# of a 2 door coupe. I called beverly hills ltd where I purchased the car new. They did nothing. I have the original temp registration from the day I purchased the car new, and the dealer typed coupe not four door and on the lease agreement. I did not notice this. Here are my issues. The coupe is more expensive on insurance - I have been overpaying since 2/2003. 2nd, am I paying a fair lease rate if the VIN# is for another body style. This car has been nothing but nightmare to deal with since the day I purchased it. It has been serviced 8 times, transmission work, 2 computers, camshaft, new radio, idle issues, brake system failed, and so on. It's a complete lemon. It is going in next week again. I have only 21,000 on the car, and drive my 2nd car more a 79 300sd Mercedes as it is more reliable then this new car. I need somewhere, someone to go to, any information would be greatly appreciated. Thanks so much, [xxx] - phone or email updated 07/18/2012 information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)

This is a new Mercedes-Benz C230 compressor engine with one thousand miles. Last month a sulfur smell emitted from the exhaust while warming. I was told this is normal. Three times this week on ignition the car shook violently and would not stop until the engine was turned off. The car is drivable and I have returned it to the dealer. They are attempting to fix it.
