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.

My exhaust manifold cracked at 100k miles. Honda should release an OEM part with a better design. This is quite expensive especially after just replacing the timing belt which ranges in the 500.00 dollars level. I wish they read how many people has complaint about this and do something about it. I bought my civic brand new and it has been a great car until now. I hope these are only big expenses I will run into. At 100k miles, I still think is a great car, but it's cetainly not perfect. Then again, what is?
