“I had my sedona 2003, the power seat recall was made 4 months before the accident(fire start above fuse box), the dealer is not telling me the true about it, because there have not been any inspectors from Kia motors coming down to inspect this minivan. There have been more than 6 months an they have not been able to start working one it or a simple as telling me why this happened.”

“I have a 2003 Kia sedona. I have had to have the alternator replaced 2 times in a months time. The dealership is saying now that the connector to the fan has melted because the fan is pulling too much voltage. But from what I understand from others, the issue is the connector and not the fan? I hope they are able to find out what keeps causing these issues and can fix this asap! I am sick of spending my nights stranded on the side of the road! Not to mention the financial strain it is placing on my family. Now I know why the previous owner traded in this junk with only 53,000 miles on it!”

“We have a detached garage, at 4:00 am our dog woke us up to her barking. She could hear the van horn blowing. When I took her out, I saw the van lights flashing and the horn was blowing. I could not stop the horn with the keyless remote. I woke up my husband, when he opened the door the dashboard was all melted, windshield was cracked, the A/C unit going up the driver's door was all melted. He finally found a place to open the hood to disconnect the battery. The mechanism to open the hood was all melted as well. The van was totaled and the insurance company sent us $3900. …”

“This van has been a problem ever since I bought it. This is the 3rd time the brakes have been replaced, the cd player doesn't work any more. The alternator with out at 40,000 miles. The fuses inside keep blowing. The air controller in the back in falling out of the ceiling. I had to leave it with the dealership for over a week so that they could find the hesitation problem it was having when pulling out into traffic. It turned out to be the distributor cable, this was at about 17,000 miles and that was also the miles at the 2nd brakes job. …”
