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.

problem #1

Aug 102013

S550 8-cyl

  • 57,000 miles


I was in unfamiliar area. Remote key would not operate. When using small key to enter vehicle car siren would not quit blaring batteries did not help. Mercedes responder told me I had inoperative "dead" key. Car of course was inoperative. No way to move car from area. Could not secure car. I had rbm in atlanta on cell phone entire time. About hour later someone took me to my home for spare key. This worked. Key was as Mercedes responder told me...... dead. The Mercedes keys are unsafe and undependable. Need to be recalled. Mercedes would not replace "dead" key per kyrus frames at rbm in atlanta. Because my car had 57000 miles on it and out of warranty. Key must be recalled due to safety concern there is no way to operate a "dead" key. Mercedes responder told me that he sees it all the time. What if"?? I had been miles from home? unsafe area? compromising situation"this is unacceptable for $100,000 car. I could be dead. Just provide a workable key Mercedes.
