The contact owns a 2016 Kia Optima. The contact stated while depressing the accelerator pedal, the vehicle hesitated before gaining motive power. The vehicle was also shuddering and vibrating. The contact stated there was no warning light illuminated. The contact stated that the failure was intermittent but became a recurring failure. Additionally, the gear shift lever was difficult to shift into reverse(R). The contact turned off and restarted the vehicle and then the gear shifter was able to be shifted into reverse(R). The contact had not taken the vehicle to a local dealer or independent mechanic to be diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 76,000.

My 2016 Kia Optima LX 1.6 has been burning oil really fast. It also has been losing power when I try to accelerate with know check engine lights on. Currently the engine has a shake to it & is un-drivable. Oil gets to the spark plugs. I previously took my car to a Kia Dealership before I had a check engine light. They told me they could not do anything because a check engine light was not on. Now that a check engine light is on I was told by a dealer that it has an engine misfire. It has been seen by a dealership. This problem could have been prevented now knowing that this is a problem for many Kia automobiles.

The Hybrid Battery continues to malfunction and, randomly shuts down at any speed (even after short engine block was "repaired" by Kia Dealership). Also, an odor of burnt oil happens often while driving the car. It is available for inspection, if need be. Safety of all drivers at risk because car shuts down on freeways and highways. It's dangerous where cars driving at speeds of 65 mph are unable to break and avoid collision. Kia calls their RECALLS "CAMPAIGNS". The Kia dealer has acknowledged this problem and has performed maintenance, however the problem still persists. I have the recent receipt of service/ maintenance on my 2016 Kia Optima Hybrid on hand. The first time it happened was on September 25, 2021. There were no warning lights or messages, the car simply shut down and had no power and was not drivable. I took it to a hybrid mechanic who ran a diagnostic test. The hybrid mechanic repaired my car. 6 months later, while I was driving my car seized on me while I was driving on the freeway going 65 miles an hour. This time a warning on my dashboard showed that there was a problem with the hybrid control system on the car. We took it to a Kia dealership and they performed a diagnostic test and said that I needed a new short engine block and hybrid battery replacement. (I have the receipts for the maintenance performed by Kia Dealership) It took 3 months for The Kia dealership to rebuild the engine block and replace the Hybrid battery. On March 7, 2024, my 2016 Kia optimal hybrid seized on me while I was driving 40 miles an hour. The message/ warning now says "Battery Management System Failure" "Possible BMS Condition." "Check Hybrid System". Kia does not acknowledge that there is a problem with the hybrid system in the Kia Optima hybrids. I've called and tried to file a complaint, however they tell me there are no problems with the Kia Optima hybrids. Please investigate. Thank you for your time and attention to this important matter.

The Car has been to the dealer several times for a transmission judder update under TSB: TRA 083 and Recently TSB TRA 098 - Both Times they have done a Anti-Judder Logic Improvement. The Car still Judders and Its a big safety concern. Many times I will go to pull out into oncoming traffic and the judder can be so bad the car wont take off. This happens several times a month. I have complained about this since I bought the car and primarily they blamed it on being a Dual clutch transmission. Years later they have now 2 TSB and the issue is not solving the problem. The imparticular dealer that I use has told me they have never had to change out the clutch on this car and dont have the tools. They also said the way that kia uses software to monitor the judder never warrants a change in the dual clutch. I believe that Kia should take responsibility and install their new updated transmission into this car.

Several weeks went by and vehicle started to hesitate pretty bad Vehicle was towed to Kia dealership on 10/04/2023 : Was told engine failure which needed replacement along with intake and several other required parts. Covered under Powertrain Warranty, vehicle was completed and ready for pick up on 10/17/2023 On 10/24/2023, on my way home from work, Dash Warning "Engine has overheated" has came on. Vehicle was towed back to original dealership. Kia reportedly found "air pocket" in cooling system. Vehicle was ready for pickup same day. On 10/30/2023, on my way to work, Dash Warning "Engine has overheated" has once again came on. Luckily I was able to get off the interstate and happened to be by a Kia dealership in the area. At this time, info is pending.

My car has been consuming oil and has locked up and will not operate. This issue has been reported to the manufacturer by several other customers, and my car is not a part of the recent recalls. This issue could have caused me serious harm, had I been on a highway, or busy intersection. My car engine now doesn't work.

I have already had to have motor and transmission replaced once under warranty. The replaced transmission was worse than the original problem. The original problem was hard shifting. Now I have intermittent hard shifting, occasional lunging forward, occasional shuddering while pressing accelerator, and feeling like there is hesitation to change gears. I have not taken it back to the dealer yet. I always get the excuse that they cant replicate the problem. It took me 2-3 years to get it acknowledged the first time.

In April, 2022, while driving on a major highway enroute to work, my 2016 Kia Optima started knocking and completely shutdown in the middle of high-speed traffic. I had the vehicle towed and was told that the recall for the engine knock sensor replacement hadn't ever been done which resulted in the engine to shutdown.

The vehicle hesitated to move after a stop. I have escaped hitting the incoming vehicles when taking a left turns as my car drives very slow after a stop and there are chances of hitting with the vehicles coming from other direction.

The contact owns a 2016 Kia Optima. The contact stated upon activating the heater while driving, she smelled an abnormally strong gasoline odor. There was no warning light illuminated. The contact related the failure to Kia Independent Recall Campaign Number SC172 (High Pressure Fuel Pump Outlet Inspection). Additionally, the contact stated while driving and depressing the accelerator pedal, the vehicle hesitated to respond and then lunged forward abruptly. There was no warning light illuminated. The contact stated that the failure had been reoccurring while driving. The dealer and the manufacturer were notified of the failure and informed the contact that she needed to pay for a diagnostic test and the repair cost because the VIN was not included in any recalls. The vehicle was not diagnosed or repaired. The failure mileage was approximately 110,000.

Driving along the interstate approximately 70 mph, the vehicle jerked with knock sound then lost acceleration speed. At the same time, the check engine light started blinking. I pulled over to the side of the interstate put the car in park. I put it back in drive and slowly attempted to accelerate again. I was able to make it home because I was only about a mile and a half away, but I the acceleration was very slow and there wasn't much power behind it. At a speed of about 45-50, the vehicle barely seemed to have much power.

My name is E........ M........ and I'm writing this email/complaint in hopes it can be resolved or you can pass this email along to the appropriate person or persons to have this matter looked into. We purchased a used 2016 Kia Optima a few years back and have had nothing but trouble, from electrical issues, recalls, transmission issues, oil consumption, and smoke coming through the air vents!!!! and there's more, the last time we had an issue and took it to a dealer for problems shifting, hard shifts, loss of power, and smoking, we were told the dealer could not duplicate the problems while driving it and that was that, not a damn thing fixed because apparently everyone is stupid or blind and I was more than pissed. On 7/13/22 the car has been at the dealer again (for almost two weeks now, but they were so busy they just got to it today) so the car is there for the same exact things listed before only this time they state the turbo turbine is bad and it's gonna be $4000 to fix it. First off NO, and secondly NO, I will not let this happen! BTW, please pay close attention to the part of smoke coming through the air vents!!!! Currently, the car is at a KIA dealer still, the general manager was to call me on the 14th and NEVER DID today is the 19th, I called today and they are acting like they don't even know me. NO warning lamps, the car can be completely out of oil, and still no engine or oil light will come on. The fact that this car has smoke coming through the air vents is of most concern, I need help dealing with this issue and will contact a lawyer if needed or if you advise me to. BTW I emailed all head people at Kia corporate and NO response from them as well. Thank you The consumer stated the general manager has the approval to move forward with the repairs and would like to rescind the complaint.

Four times in less than one year, car stutters, or stalls completely, check engine light flashes, and I have to maneuver to highway shoulder or slow lane to get towed. Very unsafe. Kia keeps it for a week, forces a software update repeatedly, sends me on my way and a few months later the sane thing again. Error codes always indicate engine knock amongst other things/an issue they know is theirs but -??have to exhaust all options before they will approve replacement-?? according to service mgr. I have a car that I don-??t feel safe driving because I drive alone and can-??t trust it to get home home so I end up in the highway at 4am every time.

The engine is burning about a half a quarter of oil every 1000 miles. The transmission studers when trying to take off and sometimes lags when you accelerate harder.
