Ever since I purchased my Kia Optima with only 14K miles on it pre-own from the dealer... the emergency brake (parking brake) has been loose and it has not been working correctly. When I park my vehicle on a downhill and apply parking brake with the neutral mode position just to see it's working, the vehicle slowly moves downhill even if the road is not that steep. It worries me that if I ever lose the breaks the emergency breaks won't stop the car. Fixing this problem on my own will cost me lots of money but I don't know if it came out of the factory like that. I've heard from other owners they have had the same problem.

Both ESC and auto hold lights occasionally go yellow at the same time. Usually goes back to normal after some period of time. This started maybe couple months ago. Brought to the dealer, but they couldn't detect any error codes.

I purchased my car in the greater san diego area back in June 31. 2015. Have approximately 8K miles on my vehicle and notice around 3K my car would jerk when coming to a complete stop. This has happened a few times approximately 3-4 time (average once a month).and today 10-27-2015, my car once again jerk but this time the engine made a unfamiliar sound. I will be taking it to the dealership as soon as possible.my car has received all schedule maintenance; per owner manuel. It has passed all Kia certifed dealer/mechanic inspection when taken in. Also, when the contact to purchase was signed it did not get a full inspection as the dealership was closing and the appropriate staff for inspection had left for the day. Notice when I got home the front passenger signal light did not work. Called the dealership to get my new car fixed and had to wait for approximately 3-5 days for the repair, at that point it also passed thier inspection.

The contact owns a 2015 Kia Optima. While driving at approximately 55 mph, the brakes failed. As a result, the contact lost control of the vehicle and began driving on the sidewalk. The front passenger side tires exploded and destroyed the rim. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 6,200. Updated 8/31/15 updated 10/26/2017
