“Over a period of time, approximately 70,00 miles on my car, the AC/heater fan motor will blow air intermittently, regardless of the fan's speed setting. Eventually, the fan stops blowing all together. This same problem has happened on my 1998 Kia Sephia as well.”

“The car died while driving down the road repeatedly. Battery leaked. Brakes had to be replaced for the entire car at 60,000 miles. The vents on the dashboard have popped up and broken. Now the defroster does not blow the air on the windshield. This vehicle was stored in a garage. The seams on the seat come undone. The cigarette lighter broke and flops in the dash. The switch to override the transmission lock is broken. The rear brake light broke when replacing the struts which you have to remove the back dash to get to. The board that is under the carpet in the trunk warped. …”

“This car has so many problems they cant all be listed.the battery melted,the tires wont stay inflated properly, the A/C broke,the cruise control broke, just to name a few. The car shakes if you go over 60 and the dealer charged me to align the front end,told me it needed to be done every 6 months.also said I should have known the battery would melt,its korean.”

NHTSA complaint #762823, filed 2002-06

“I am unable to start my car in cold weather. Anytime it gets below 30 degrees, the car will crank and not turn over. I tried replacing the battery. That did not work. The car otherwise starts in warmer weather. This is unreasonable. I can't be stuck in the wintertime with this vehicle. I've heard there are others who have this same problem. Maybe you should look into this and maybe process a recall for this issue.”
