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.

When it is hot and the sun is shining down on the vehicle for a long period of time, the drivers door and rear passenger door locks will not operate from the key fob" when it cools down such as evening or early morning the locks work just fine from the key fob? seems to be related to hot or cool weather. No clue at this point why I have to work the locks manually when it is hot outside"

Power door locks will not work at times both inside and with the remote preventing all ability to get out of the vehicle. This occurs when the car is at a stop both while running and not running. I generally do not try to open the doors while I'm driving.

Went to go out(6:30 am) and found that my trunk lid was unlatched, not open, just unlatched. Found out by it showing on my dashboard. Yesterday, 9/3/15, neighbor knocked on my door (2:45 pm) and told me my parking lights were on. I had come home at 7:30 am. I had gone out with a neighbor a couple of times, lights were not on. Last time was around noon.

The contact owns a 2010 Kia Optima. The contact stated that the four power door locks intermittently would not lock or unlock when accessing with the key fob, automatic door locks, or manually. The failure occurred on separate occasions and became progressively worse. On one occasion, the driver had to exit from another door due to the lock failure. The vehicle was taken to an independent mechanic, who was unable to locate the failure. The manufacturer was notified of the failure. The approximate failure mileage was 75,000.

Various doors will not properly lock/unlock from the electric switch and the key fob. This is an interment failure affecting multiple doors in the vehicle. Different doors locks are failing at different times, both locking and unlocking. Based on my research on the internet, this affects a significant number of 2005 to 2010 Optima's. this defect could cause occupants to be trapped in the event of an accident or emergency.

Our vehicle started only unlocking the 3 passenger side doors, when using the keyfob to unlock. The drivers door will stay locked and you have to manually unlock vehicle with key. Now 2 of our other doors(both rear) dont unlock. All the doors do not lock with the keyfob and when we push the lock button inside the vehicle. We have to manually lock/unlock the doors, which is a pain in the butt when you have small children!

We have been having electrical issues with our 2010 Kia Optima, which currently has 45000 miles on it. The TPMS, (!) and the airbag "off/on" lights all go off and on continually. They will be on for a few days, then go off and stay off for an undetermined amount of time. The brakes also jerk our car very roughly forward when we are braking. Even if we are going 5 mph, we press on the brakes, then the car gives a big jerk before it comes to a complete stop.
