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.

2013 Kia Optima Owner Comments

Optima 4-cyl

My 2013 Kia Optima's brake and gas pedal will vibrate/grind while driving in wet conditions. It started the day I bought it. While I was signing papers, it started to rain. During the drive home (immediately) I noticed vibrations through the pedal. I asked about it and they stated it was normal. Since it did it immediately, now I see similar complaints and no longer think I am crazy. I have had this vehicle since October 2013 and the issue persists also my backup camera sometimes does not engage. A few times the radio system gets stuck on stupid (wont turn on), but this only happens when the back up camera has issues. And this week 7/2015 my jukebox stopped working properly. Luckily, I found the reset switch near the volume control and it works again :) MA 10/8 updated 3/22/2016

My 2013 Kia Optima ex brake will vibrate/grind extremely bad under my foot. The car brake does this every time I am driving in wet conditions. The first time, which was about 2 weeks after getting my car, was after I had it washed. It also does it while driving in wet road conditions. I contacted Kia at the first occurrence and was told it was my ABS system, followed by a description of what that means and it's function. However, I know this is not normal ABS performance, as would any other driver. Not only does this malfunction distract my attention when it happens, it contradicts the purpose of ABS! it scares me when it is happening, enough for me to loose Focus. This has been happening for approximately 28 months so far.

I was driving down a moderately steep slope and when I applied the breaks to make a right turn I could feel a shaking on the break petal about a 20 second duration. This has happened twice. Both when I was driving and my wife was driving.

I was driving my car down a hill, I had the right of way so I did not need to engage my brakes at a stop light at the bottom of the hill. The emergency parking brakes automatically engaged for no apparent reason. I could have easily been hit because of this malfunction. I had to pull over in a parking lot and before I could park the car, it completely locked up as pulled in. I was forced to stop in this middle of a narrow parking lot blocking cars from being able to exit their spots. I called Kia roadaide assistance, who instead of getting me help, transfered me to a local dealer who was unable to provide any help. Not only did my car fail me, Kia cusotmer service did as well..

Vehicle in reverse backing up on steep driveway, foot on fuel pedal, car began its automated hill holding function, while in reverse, heard high RPM, transmission was slipping into neutral, car began rolling forward, put foot on brake, brake failed, car accelerated rapidly, and engine died, then hit the wall inside the garage. I estimated, speed at time of impact approximately 10 to 15 mph. Noticed another entry filed similar to this, had same fuel, brake fail symptoms.

The front brakes on this vehicle lock up really easily on slick roads, they are extremely dangerous. I took my vehicle to the dealer but they claimed they were operating to specifications for the Optima. I'm speculating, but they appear to work as though some engineer set them up to work on roads that don't have ice or snow on them, not really understanding or realizing that we have ice and snow on our roads, here in the usa. I don't know where this vehicle was designed or engineered, but it really appears to me that ice and snow covered roads were not accommodated for. I think they are extremely dangerous and have a great deal of difficulty stopping the vehicle on icy, or snow covered roads safely and without the front wheels skidding out of control. The anti-lock feature does release them but as soon as they apply again they go into a skid.
