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.

2004 Honda Civic Owner Comments

problem #1

Apr 302004

Civic 4-cyl

  • Automatic transmission
  • miles


The advertised mpg of my Honda hybrid for city driving is 48 mpg. I have never gotten better than 38 mpg. Honda says there's nothing they can do about it and just advertising that it will get 48 mpg doesn't mean it will get that actual mileage. I believe it should at least be close, not 20% less than advertised. I paid extra to buy a hybrid automobile that is supposed to perform much better than it does. False or misleading advertising for any consumer puchase should not be permitted, especially when it is a major purchase for an average consumer to make.
