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. Notes: The only reason we don't give the 2010 Kia Rio our top award is because of poor side crash test ratings.

Took my car to get fixed, and looked at the 2nd cyl.. apparently, tons of people are having problems with the 2nd cyl. After looking online about it. I had them try all my coils and its not a coil problem. I had all spark plugs changed and tune up was done. There is absolutely no reason my 2nd cyl. To be messed up... " Kia I'm so disappointed in my car, why are so many problems coming up" my car is not even 5 years old!!! I expect to get answers on this and it be taken care of, I will not be paying for something when I've done my part in maintain G my car.

We were involved in an accident where we rear ended another vehicle. The other car was at a standstill and we hit them at about 30 mphs. The driver and myself both had seat belts. The driver injuries her left knee. The airbags did not deploy. I think that if they did her knee might not have been injured because she would not have slid forward upon impact..

Traffic came to a sudden stop, I could not stop in time. I hit the tires of a semi trailer, that collision threw me down an embankment where I hit a tree head on. The air bags did not deploy.
