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.

This is a 2004 Mercedes C230. Check engine light went on. I went to dealer within 15 miles of warning light coming on. I was told that there was an oil leak and that it had dripped over the wiring harness. It would cost $3,500 to repair. I have never missed a maintenance on this car. They said the this happens because of where the O2 sensor is located. This is a defect and design flow created by mb. They should do a recall to protect the wiring harness
