I am very pleased to announce that I traded-in my 2002 Kia Sedona. After only 9 months (with about 1-1/2 of those where the vehicle was completely undrivable) and ~8,000 miles, I am free from the worst vehicle I have ever owned-- make that-- ever driven or ridden in.
Because the dealer I traded it into refuses to even keep it on the lot, I had to accept auction value. When offering the low trade-in amount, they specifically noted that, because it is a Kia, it is practically worthless.
I wound up with equity of -$4,000, but I had to cut my losses. I highly doubt that the vehicle will make it to 150K miles without needing at least one major and multiple minor repairs. I feel sorry for the next person who gets tricked into buying it (or for anyone who buys any Kia for that matter). I'm not financially well-off by any means, so buying the Sedona is a decision that will haunt me for years.
I won't rehash all my problems with this vehicle or my feelings about the Kia corporation. They are spelled out in these two threads at KIA-forums.com:
