Intermittently car will shudder (jerk forward and slow, jerk forward and slow) many times when accelerating, either from a stop or while accelerating from low speeds (less than 45mph) it seems possible gear changing is not smooth. And can be dangerous when attempting to merge into traffic as car does not accelerate as it should. Have taken the car to Kia who report that nothing was wrong with car when they test drove it. Problem seems worse when it is hot or cold outside.

So I got the software update for the engine recall. On the 24th, engine light cane on. Waited for an engine replace for 2 months, then they told me it was the knock sensor wire harness. They replaced that and gave me back my car. 1 week later, same engine light. Took it in they wiped off the engine light, drove it for a week and tild me nothing was wrong with the car. Speakless on the way Kia has handled this.

A month after doing the recall for the engine update, the harness has to completely replaced. I was on the expressway went it started shaking and would not go over 63 mph. The engine light kept blinking.

Around the first week of February this year. They did a recall on the engine adjustment and the following weekend the engine failed. I was able to get the car into Kia napleton carmel/indianapolis this was February 11th I believe. Within ten minutes the operations person came back and said they had a rental coming to pick me up. They had to replace the engine do to whatever they did to the car in the recall. I thought about this for awhile, I was going to purchase the car at the end of the lease. The large warranty is just about up in time, and should anything occur outside of the power train, it is on me. That mean if it takes months or weeks to fix the car, I need to lease a car and wait for the part. I became very irritated on the 15th day of waiting. That was now all most a month ago. Kia napleton has now had the car for a total of five weeks and not engine in sight. Enterprise told me my rental was extended to April 14th which Kia motors if paying. I have complained from the dealership to Kia lease, to Kia motors and back to the dealership. A lot of run-around. Finally, they have issued a letter to permit me to pay $19,040 to buy out the lease or around $11,000 to find a new lease or just $3,000 for my troubles and keep the car. My worry is if something else goes wrong, what if I am waiting for five weeks or longer for a part to arrive from asia, and what if it happens on the open road. I want Kia to take me out of the lease without damages to me. I am not pleased to have had Kia destroy their own engine and now make it my problem. Kia has continually referred me between departments and one individual told me to contact my own insurance agent. They cannot guarantee me that the car will fail in some form for the remainder of the lease which is just around 16 months out. I took the letter from Kia over to napleton K

- Waterville, ME, USA

While in drive, randomly at a complete stop, the engine will die. I will have to put the car into park, turn the key completely off, and then try to turn the car back on. This can take several attempts to finally get the car started. Only the engine dies, the radio, lights, etc stay on without any interruption. This has happened at stop lights, stop signs, in a car pool line, all while not moving.

- Hoover, AL, USA

When decelerating, the car jerks at exactly 35 mph whether im on the highway or in the city and this happens. I have been to the dealership 3 times for this issue and they have even drove my car themselves and felt the same thing that I was feeling and all they say is that without a check engine light threr is nothing they can do about it and I just have to "live" with it. This is ridiculous and Kia needs to address this issue before it causes any accidents or worse death. I spent way too much money on this car for it to be having these issues. Brakes are supposed to be a safety feature not a safety hazard.

- Edmond, OK, USA

Car stalled for no reason while sitting idle at an intersection. It was towed to the Kia dealership in san diego. The first day, the dealership claimed it found nothing wrong and there were no error codes. The next day, it claimed to find a hole in the oil pan. It refused to start the car again until we paid $500 to fix it. There was no oil in its parking space or the place where that it stalled. We took it to another mechanic who found the hole. He said there was more than sufficient oil to turn it over, and if the hole has been there long, all of the oil would have leaked out. We suspect the dealer did this intentionally to create an excuse to avoid paying for a new engine if it turned out to have metal shavings and catastrophic failure like so many other Optimas.

My Optima seems to hesitate or studder when accelerating from a stop. It reminds me of a gear slipping but my car only has 11,145 mi on it so there's no way that's possible. This has been an ongoing observation for months now. I've also had one of my mirrors not go back to normal position after I moved the car from R and began to drive. I had to pull over, place the car back in R, and flip back to D for the mirror to go back to place. Lastly I've noticed my driver seat seat warmer button isn't lighting up like it used to. When on high, only 2 lights are on. I recorded a video of it vs how the passenger seat works but I don't think I can upload it. I've at least taken photos of it in each level. This has been for about 2 weeks now. Mileage listed on report is what I'm currently at but the studdering has been since 3,000mi or

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.

- Smyrna, GA, USA

Shutter/hesitation upon take off. I signed my lease on 9/29 and was at the service dept first of 7 times on 10/4. at first I was told the car had to "learn the way I drive" that there were no issues with my car. Since then the dealer has "reset" the transmission, changed fuel injectors, replaced transmission, and now has done 'several updates' (seriously?) this car has nearly caused accidents on numerous occasions. When I asked the tech if he would drive his family in this car I got no response. I have asked on the last 2 trips to the dealer for them to simply replace my car. I am currently consulting a lawyer.

- Charleston, WV, USA

I bought my car 6 months ago, I have performed all required maintenance for the vehicle and at 17,000 miles there was a ticking sound while I was driving on a busy road with my handicapped mother. There was a loud noise and I thought I blew a tire, the engine seized up and I was in the middle of the road, I had to call emergency road service to get my mother and I safely home. After getting the vehicle towed to the Kia dealership I am told the engine is needing to be replaced because a rod was thrown threw the motor. We were very lucky that neither one of us was injured with this incident however others may not be so lucky.

- Orange City, FL, USA

This vehicle suffers from a hesitation during take off. According to Kia this hesitation come from a 7 speed dual clutch transmission(dct). Which causes the vehicle the driver to feel a shudder sensation. This vehicle has a double clutch. I have taken my 2016 Kia Optima dealers for repair to this problem without any solution. Runs rough.

From a dead stop driving around, releasing the brake petal from a stop and getting ready to get going, the car shutters a bit and/or both the engine feels like it's gonna stall. Hesitation to get going.. does it in all 3 drive modes. Dealers says npf.. of course and said maybe quality of gas, I use top tier gas only.
