Cruise Control Problems of Kia Motor Optima

Issue started 2 months ago. Noticed that vehicle acceleration is sluggish. Sometimes I have to take foot off the acceleration pedal then depress it again in order for vehicle to accelerate. Acceleration is unreliable and dangerous. Electronic stability sensor also started lighting up and cruise control became inoperable. Also noticed that my tail lights lit up on its own (and did not turn off) while vehicle is parked and fob not near vehicle, draining the battery. Police came by in the middle of the night to report that my tail lights were on. Tail light did not turn off when pressing the fob unlock/lock button. Had to restart the engine, drive around the block then turn off engine before the tail lights came off. . . But it turned back on again on its own that same night (in the middle of the night) and had to repeat the process. My battery was drained and had to replace it 3 days ago. I thought it was a battery problem (and was informed by dealer that it was probably a battery related issue) but problem persisted. Read reviews and this seems to be a running complaint with issues on brake pedal stopper or brake sensor stopper. Will bring vehicle to dealer in the morning.

The driver door lock does not work. It is the only door that will not lock sometimes. Other times it is the only door that will not unlock. The cruise control does not always want to work. It will say cruise but will not let me set it.

While driving on a highway with cruise control active, I was unable to turn off the cruise control with the steering wheel control buttons. The cancel and set buttons had no effect when pressed. The car remained traveling at the set speed. Tapping on the brake pedal did cancel the cruise control.

I first noticed a problem with my vehicle when the cruise control would randomly disengage while going down the interstate. Then a couple of weeks later I was making a left turn across a two lanes of traffic on a city street. When I first pushed the accelerator the car started to go and then suddenly I lost all acceleration. I let my foot off the accelerator and then pushed back down and was able to go. This was a very dangerous situation as I was stuck in the middle of two lanes of traffic for several extra seconds longer than necessary. A similar situation happened a couple of more time and when I parked the vehicle at home I noticed that brake light was staying on after I got out of the car. I took the car to the local kia dealership and they replaced the brake sensor which fixed all of the above problems. I would like to not that Hyundai issued a recall on the nearly identical sonata for this same issue and did so years ago and yet nothing for the Optima.

The contact owns a 2014 kia Optima. The contact stated that while the driver was driving at approximately 50 mph, the air bag warning light illuminated and the cruise control stop functioning. The contact coasted to the side of the road, after a few minutes, the contact was able to resume driving. In addition, the contact stated that while making a right turn into a parking lot there was a rattling noise coming from the interior of the steering wheel. The vehicle was towed to the resident of the contact. The vehicle was taken to an unknown dealer, located on delsea dr, vineland NJ, where it was diagnosed that the air bag clock spring cable detached and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist her with the failure and was to go through the vehicle warranty for the repair. The approximate failure mileage was 97,000.

When the car encounters a hill and needs to downshift, either to climb or to hold back the speed when it descends, the cruise control remembers the downshift and will not return to high gear until a) it is manually overridden, but will still downshift up to 2 gears, when the lever is placed back to automatic or, b) when the cruise control is turned off. The cruise control also belatedly reacts to loss of speed control and overcorrects with too much power, resulting in a crude ride, as well. The workload is increased dealing with getting the car to attain top gear on flat roads, and is creating unsafe conditions, in my opinion. I have attempted to get this attended to at the dealership, and they continue to not fix the issue, as well as inform me I shouldn't be using cruise control on hills. My 2014 kia Optima did not exhibit these issues, nor any other of my cars which had cruise control. There is a problem and these people will not fix it.

I have been experiencing issues with my 2016 kia Optima since I purchased it on September, 5th 2016. A short time after owning my new vehicle, first the car started to hesitate when starting as if it was struggling to start, the push button would turn red and the indicator lights would light up on the dashboard as if the key was not recognized in the car. The car would also self accelerate. On or around August 16th or 17th the car stalled out while it was being driven,we attempted to restart the car and it turned on like normal so the tow was canceled. , the service writer & kia all have copies of the videos the mechanic has also told me he was able to duplicate the issue, the solution was to change the fuel pump and service the fuel delivery system. Upon the services being completed we were contacted by the service manager, and kia that the car was ready to be picked up on September 6th 2017. While driving the vehicle home we noticed some hesitation while idle, also some strong acceleration when taking off from red-light or stop sign. While parked we noticed some strong vibration from the motor which the car had not had previously before service. Also after several attempts of starting the car, the car would either start rough, and also still had the same original occurrence as before with the key not being recognized in the car. With the car not fully starting and the push button turning red with the instrument panel lighting up with the key not in car light along with some others. On Thursday September 7th, 2017 at about 4:30pm I had the cruise control set to 80 mph, the car hesitated a couple times, then self decelerated to 73 mph, reaccelerated to 82 mph then self adjusted to 80 mph, I contacted the dealership right after the occurrence I was told I had to wait to bring the car back in they had no loaner vehicles, not to use the cruise control feature.

Cruise control "cancel" button needs repeated pushing to activate. A single push of the cancel button actually seems to accelerate the car.

The cruise control is inoperative. The cruise control light will come on, but you cannot "set" the cruise control. I have read online about several other kia makes and models having this same issue. As far as I can research, there is not a fuse for the cruise control.
