I was in a crash and I have to say that this is a problem. After I received my car back from the body shop the car has been malfunctioning ! the 2.7L has stumble on and at acceleration the failure is the throttle position switch this is a safety problem for all driver's that drive a 2007 Kia Optima. The malfunction occurs five time's in one day. This problem may cause severe or fatal injuries to the occupants in the vehicle. Nothing was done to correct the failure and the old throttle position switch is available! I really thank that this is found to have a defect that affects safety and the automakers need voluntarily announce a recalls on all the 2007 Kia Optima that have the same throttle position switch as this vehicle.

Bought a 2007 Kia Optima in July 2010, after 3 months had to have brakes and rotors replaced. Now only a month later the brakes are bad again. I have to take it to the shop. The back driver side brakes are grinding. The car continues to squeal. I talked to the dealership where I bought the car this is not covered under warranty. However when I bought the car they said there was more than 50% brake pads left. When I changed them the first time they were completely gone in the back on the drivers side. I do not feel that I should have to be replacing the brakes again, just one month later. Something is wrong with that. I am not happy with my car or the dealership at the moment.
