I bought a new 2006 kia optima ex in apr 2006. sept 2006 the key fobs quit working and the pass side back seat does not secure itself in place at the bottom of the seat and stay/taken to a dealership and fixed. july 2007, the key fob again quit working/taken to the dealership and i was told a tsb was out on this problem and they would replace the receiver which was done. nov 2007 after the tsb supposedly was taken care of, again the key fob quits working/dealership has again reprogrammed to work again and currently they continue to work. this car handles extremely poorly and in my opinion is a safety risk. it seems to have a pretty loose suspension and a lot of swaying when driving. the car pulls hard to the left causing one to have to hold the steering wheel tight to keep it from taking nearly a 45 degree left turn while driving. when applying the brakes, the car pulls both left and right/usually left. when driving over a smooth dip in the road, it feels the front tires actually leave the ground slightly causing the steering wheel to vibrate right/left quickly. this vehicle also handles extremely poorly on icy roads. this is without any question the worst handling vehicle i have ever driven...concerns me as i drive on the highway about 35 miles to work one way daily, and drive in windy as well as snow and icy conditions fairly frequently. at about 15,000 miles, the latch on the gas door doesn't want to stay closed after you fuel up and the electronics that operate the side view mirrors intermittently do not work. feb 2008, my car reached 30,000 miles and when washing it last week, i noted an area of paint peeling off on the driver's side door trim (black), as well as the chrome paint starting to bubble. i took pictures of both of these areas. since driving this car off the showroom floor, it has been garaged at both work and home. last week (feb 2008), driver's side seatbelt quit retracting. *tr

Kumho radial tire on the back (passenger side) of a 2007 kia optima failed at approxmiately 70 mph. the steel belts in the tire broke and the tire tread separated from the walls. there was no damage to the treat itself, and there was no evidence that anything other than structural failure (such as a foreign object) was responsible for the tire's failure. *nm

I have approximately 13,800 miles on this car (kia, optima, lx, 2006), and the tires (4) have been changed already. the tires sound hollow, and ping, besides pulling to right and left. the second set are doing the same thing. i think and fell that kia should be involved in this problem, but they say its not there problem. these tires are on a kia? *tr

Dt*: the contact stated while driving various speeds on paved roads, the front of the vehicle had a severe vibration and made a roaring noise. the contact inspected the vehicle and determined both front tires were excessively worn and the tread was separating. the dealer was notified. the tires were hankook, optimo p205/60r16, dot #t7bkbwh. *ak
