“In my Kia Sedona minivan I had purchased brand new only because of the warranty I took kids to school oil light came on and when I tried to crank back no. They towed to the local Kia dealership and the said it was not warrantable.”

NHTSA complaint #10181374, filed 2007-02, 83,650 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.”

“At approximately 55,000 miles my Kia Sedona van had a broken engine mount. Now, at approximately 65,000 the van has an additional two broken engine mounts -- that is a total of three broken engine mounts in only 65,000 mile's!! This is incredibly dangerous -- and this shouldn't happen with this frequency, if at all!!”
