While parking 2007 Optima I was unable to put the vehicle in park or take out the key. The shifter linkage and cable had broken. I used the emergency brake to keep the vehicle from rolling. I took vehicle to dealer (summit Kia, waterford, mi) they replaced the vehicle shifting linkage at a cost of $750. The dealer stated the cable broke and when I asked if the part was defective they stated that it was not unusual to have to replace this on the 2007 Kia Optima. The vehicle has 108,000 miles. In 40 years and many vehicles I have never had this go on any other vehicle I owned.

The contact owns a 2007 Kia Optima. While driving approximately 35 mph on normal road conditions, the trunk warning indicator illuminated on the instrument panel. Unexpectedly, the trunk unlatched without assistance. The failure occurred spontaneously. The driver pulled over to the side of the road and closed the trunk door. The vehicle was taken to an authorized dealer four times for inspection, but they were unable to duplicate the failure. The failures occurred on thirty separate occasions. The failure mileage was 6,000 and current mileage was 14,000. Updated 03/18/09. There was a hesitiation with the vehicle between 40 and 50 mph, there was a burning smell when the vehicle was turned off. There was no heat coming from the lower heating ducts. The cruise control came on by itself
