I was at a stop sign when my car shut off. Now it won't start. Took it in to check it out and found out that the motor seized up. I know that there is a recall on the engine for the same problem on other models. Not safe to be driving the cars. Could cause a major accident resulting in possible loss of lives. This model needs to be recalled before this happens to anyone else.

I was driving normal and started to hear a hissing noise in the front of vehicle. A vehicle cut in front of me I hit the brakes and another vehicle didn't slow fast enough and I went to hit the accelerator and had no power as usual and swerved to avoid the collision. I called dealership they said possibly my wastegate is out of normal voltage or need new turbo. I had a second opinion and they noticed the bolts and nut to service wastegate are rounded showing an attempt to maybe service or repair but unsuccessful. The turbo shows full function just inadequate boost.. The manufacturer has a bulletin and testing procedure Released on WASTEGATE test and adjusting procedure if needed as possible remedy. But I saw no recalls for my vehicle so reporting what I almost experienced and glad I have good driving experience to avoid an accident or life threatening situation behind the wheel of this vehicle now I don't feel safe until its proven resolved not just temporary fix.

I'd had no mechanical issues w/ my vehicle, whatsoever & all routine maintenance is done on time. While driving on the highway one day & suddenly all the warning lights came on & lots of smoke coming from under the hood. Pulled to the side of the road, had it towed to the nearest Kia dealership. After a few days, it was explained to me, by the service team that my engine was shot, but I wasn't given an explanation as to why. There were no recalls at that time on the hybrid vehicles; however, I just got a recall letter for my Optima hybrid, dated 1/27/2021 that described the very thing that I experienced with my car. This prompted me to visit this website to explain my issue.

My check engine light is blinking; faulty acceleration on highway and going upgrade (uphill), vehicle jerking on local roadways; auto zone says its a faulty knock sensor. It could possibly be an issue with the engine but I'm not sure.

I have reason to believe that my car has been hacked due to an incident that occurred approximately one week after being aggressively followed by a mysterious black Nissan SUV with pitch-black tinted windows at my work location. During the incident in question, I was on the phone with 911, with the bluetooth of my car and phone on and connected, calling about a red car that appeared to be following me. I drove around my block and lost the red car but when I returned back to the street where I live, I slowed down as I noticed a slow-moving black SUV with pitch-black dark tinted windows (reminding me of the black Nissan SUV that I encountered a week prior at work). I remember its headlights being off. This time, I was in close proximity to the black SUV- it was on my left side driving the opposite direction and it also appeared to slowed down and got parallel to my vehicle). When my car and the black SUV where almost next to each other, all the interior lights of my vehicle turned on and I heard a sound that sounded like all the doors unlocked. As a petite female who was driving alone at 10pm or later that night on an empty back street, I got terrified and quickly pushed on the gas to get away from the black SUV. With all the interior lights on while trying to drive at night, I had no visibility whatsoever, so I kept pushing the light switch by the driver's side, but no matter how many times I moved the switch, the interior lights did not turn off. After driving, I estimate, 1000+ feet, the interior lights turned off and I regained visibility. At that point I could see my apartment was coming up so I quickly drove into the gated parking area of my apartment complex. As I recall the incident, the light switch was on "door" when I was attempting to turn it off while driving. This incident reveals security/safety vulnerabilities in my vehicle.

Driving car for no longer than 45 minutes. When approaching a green light my car would not accelerate. The light turned red so I had to come to a stop. As I did, all my dash lights came on and my car sputtered. The car then turned off. I tried to restart, but nothing. It began to smoke badly and I rushed out of my vehicle. There was a cop, conveniently close, who stopped and poured water where the smoke was coming from. It continued to smoke but not as bad as before. The car would not turn over still and I was forced to pay to have my car towed out of the middle of the road. After sitting, with engine off, there is still a sting burnt smell coming from under the hood and inside my car.

Since about 40K miles my steering has clicked, locked, and missed and has gotten worse to the point that I have almost been in a few wrecks from inability to control steering. A mechanic friend of mine told me there was a recall for this and to call Kia of chattanooga (who I purchased from) to look into it along with other recalls I may not know about before taking a trip accross country with my son. I have tried calling and the dealership hears recall and hangs up on me. I was able to leave one voicemail for the manager but was never contacted back and continue to be hung up on. My concern is mostly with the steering and possible bearings with engine. Steering will click even at a stand still, locks and misses while in motion rather badly. This has been happening since around 40K miles. Unsure of any other safety related recalls as I had moved multiple times and belive that is why I did not get letters.

There are a few recalls on my car. An appointment was scheduled to go to greenway Kia in longwood, fl. However, upon arrival they tried to charge us for the diagnostics and stated that the recall is not valid without us paying for the diagnostics. Then they proceeded to advise us that the parts that we needed under the recall were not covered by the recall and that we would need to pay thousands of dollars to then mention that it would be easier for them and cheaper for us to just buy a new car. We decided to leave and try to do more research. I did call our mechanic he confirmed there were recalls for our vehicle. I then called another Kia dealer and they advised there were recalls on our car and that there would be no charge for the diagnostics and/ or repairing the car under recall.

Most recently while driving my car with vehicle in motion on city street (a straight road) it all of a sudden drops power and I am unable to get the car to accelerate without push down very hard on the pedal until it finally decides to speed up, once this occurs the traction control light appears on the dash and does not disappear and will not disappear until the car is shut off and restarted and the loss of power continues to happen until the car is powered off. After realizing this issue I turned off the car and let it sit a few minutes and when I powered back on and drove again the same issue occurred and the traction light reappeared on my dash. I am concerned this could be a faulty programming issue that is telling the car the traction is needed when it is in fact not. This is a safety hazard as there is no way to predict when this power loss will happen and does so in the middle of driving which slows the car way down and could cause an accident and also having to continuously keep the accelerator down until it decides to regain power is dangerous because it will suddenly ramp up the RPM and take off. This is a major concern and could be happening to other consumers.

Been having issues with the driver side window for some time. When pushing the window up, it keeps going back down. After mentioning it to the Kia dealer they said there was nothing wrong. Well, just yesterday the entire window made a cracking sound while trying to roll it up while driving. Then the entire window just fell all the way down and now it won't go up at all while driving on the freeway. Not sure if it came off the tracks or if it has something to do with the motor. After doing some research I have noticed that a lot of Kia owners have or had that same issue. This is definitely some kind of defect/problem if so many have the same issue and it should be recalled since it seems like a problem with the manufacturer.

Hello I am not sure if this is the correct place to seek information or file an compliant about what I think is a defect in Kia motors paint on this models that was painted with white. While driving I seen paint start to fly off my hood of car. My car is kept inside so this should not be happening. I contacted Kia motors and rep stated they are aware of issue but cant paint all cars with flaking or peeling paint. I asked if their is a known issue or problem with model and year why would you not offer some type of reimburse/ assistance or recall to correct. She stated to hold and came back to say her boss said the company would go broke. After the conversation phone hung up.
