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.

2003 Kia Sedona Owner Comments

  • Automatic transmission
  • 66,000 miles


I purchased my 2003 Kia Sedona in November 2005. So far the following have been repaired or replaced: Front hub assembly left side once, right side 2X's, the alternator, the wiper motor, two recalls, the battery, now at 65,000 miles the transmission is shot and needs to be replaced and the timing belt has been replaced. However the warranty company says they wont replace it because the cost of the repair exceeds the value of the car. This is simply outrageous. I have brought the car to the dealer for every service needed. Transmission, oil filter ect.

I have numerous complaints on my 2003 Kia sodona. I purchased the vechile in June of 2003, we have since taken the van in to the dealership for a variety of problems. The aircondtioner stop blowing cold air with in the first three months of owning it, this has been fixed. Paint has peeled off the front bumper, seat belt ratcheting system stopped working, engine mount needed replacing, tansmition needed adjusting three times, and the last problem was the vechile would lock when ever and where ever it felt the need to. I locked my self out of the car with my children inside many times. The dealship replaced a main panal inside the door. Despite, all the times I have taken it in, at least twice for every problem, the dealership refuses to give me a car, mind you I have two children to cart around all day. I am extrmemly peeved about this van.
