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 Kia Rio Owner Comments

problem #7

Nov 062010

Rio 4-cyl

  • 68,040 miles


I was at a stop sign and my 2004 Kia Rio died, I pushed it to the mechanic and was told the timing belt lost its teeth and there is now no compression in 3 and 4, the mileage on car is 68040. I was told basically the engine is toast and I wasn't even moving, I was told by a couple of mechanics that the belt that Kia used is faulty. The owners manual says replace 60,000 miles but replace it 105,000 in California. How would a belt be bad in 49 states except California. I found on auto NHTSA action #10015272 service bulletin # 289221 report dating Jan 1 2005 improved timing belts for 04 Rio and optima.

The contact owns a 2004 Kia Rio. While pulling up to a parking lot at 20 mph, the vehicle suddenly stalled. The contact attempted to restart the engine, but was unsuccessful. She was near a tire shop at the time and the mechanic stated that the timing belt failed. She had the vehicle towed to an auto repair shop and was informed that the timing belt failed and the engine valves needed to be replaced. The manufacturer stated that she would be responsible for the repairs. The vehicle is in the process of being repaired, but the contact believes that the timing belt should not have failed within five years. The VIN was unknown. The current and failure mileages were 80,000.
