Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2003 Kia Optima Owner Comments

Optima 6-cyl

My wife noticed the car pulling to the right and called her brother. He looked at the vehicle that evening 12/30/2013. He drove the car pulling onto a highway, the car would not move -- neither forward nor reverse. He pushed the vehicle off the road and the front axle dropped out of the transmission. It was towed and the garage notified us that the front sub-frame had corroded. Online research reveals NHTSA recalled Kia Optima (2001-2004 model years) on May 27, 2009. I called the dealership on 12/31/13 where the car was purchased. The customer service rep said the recall did not apply to our vehicle. The kmc was contacted on 1/2/14. I was informed that the recall was based on "salt usage of 20 states and DC." This interpretation of the NHTSA recall id # 84125 needs direct clarification from the NHTSA. The original recall letter states: "kmc is recalling model year 2001 - 2004 Optima vehicles originally "sold in or" currently registered in the states of (20 + the District of Columbia)." Since I purchased the vehicle in Indiana my vehicle should be covered by the initial recall. Regardless, the safety issue of the vehicle should warrant a notification to all owners of potential problems for this vehicle. This mechanical issue could have resulted in a catastrophic event. This complaint is also associated with ODI# 10558172.

The contact owns a 2003 Kia Optima. While driving 35 mph, the vehicle decelerated when the accelerator pedal was depressed. The contact stated that the gas mileage was poor as well. The dealer was unable to diagnose the cause of the failure. The air filter and oil were replaced, however, the failure remained. The current mileage was 82,591 and failure mileage was 82,002.
