2016 KIA OPTIMA Power Train Problems

Hear the driveshaft clicking and doesn’t accelerate like it should

The car is burning oil rapidly causing potential issues with the transmission and engine. The oil burns and does not leak after a few hundred miles and has to be refilled continuously causing alot of money and potential issues with other components of the car. I notice jerking when accelerating and smoke if dont fill every 1 to 2 weeks.

Complaint Message – 2016 Kia Optima Engine Failure Without Oil Light Warning I am the owner of a 2016 Kia Optima (VIN: [XXX] ). My vehicle suffered complete engine failure due to oil starvation — without any prior oil warning light or indication. The engine died while driving, and it was only afterward that I discovered the engine oil was extremely low. The oil pressure light never illuminated at any point to warn me. I am aware that Kia previously recalled earlier model years (2011–2014) for similar engine issues under Recall SC147 and others, related to the Theta II engine and oil pressure-related failures. Many owners reported the exact same symptom — catastrophic engine failure without oil light warnings — that I am now experiencing in my 2016 Optima. Although my model year is not included in the existing recall, the failure pattern appears identical. I believe this presents a...

Several safety-critical systems failed on this vehicle. The engine (Theta II 2.4L GDI) failed due to rod bearing wear, causing sudden power loss on the highway. The vehicle entered limp mode, once at 50 mph in 2018 and again at 70 mph in 2025, and had to be pulled over quickly to avoid collision. Additional issues: all four windows failed at different times, leaving them stuck open and creating safety risks in weather or emergencies. The trunk latch failed, causing unsecured cargo risk. ABS, TPMS, and traction control warning lights illuminated repeatedly, indicating possible loss of critical safety systems. A loose wiring harness caused the turn signal bulb to burn out repeatedly, reducing visibility and signaling. The dealership performed the KSDS software update after I reported engine trouble but did not resolve the issue. The engine soon failed completely while driving. Other issues, such as the fuse box blowing fuses...

Engine failed at 52.350 miles due to excessive oil consumption confirmed by a Kia dealership. Car was driving fine on 5/1/25, on 5/2/25, car started to stall with loud clicking noise, and wouldn't move fast, which then activated the check engine light.

I went to the Garden Grove Kia to get my new 2016 kia optima repaired for their knock sensor settlement repair. By their own terms of the agreement all original and subsequent ow ers can get vehicles repaired. They took my vehicle information, I gave them all details of my ownership of the vehicle and they said they would fix it. The next day I rented a trailer to take the vehicle to get repaired (vehicle still runs but don't think it's safe to drive like that) and upon arriving, a worker comes out and tells me that they will not repir the vehicle because I just purchased the vehicle. Craig, the manager, also refused to see ownership documents but gave me 2 things; legal advice saying that I should sue where I bought the vehicle from and a paper that said they will not fix cars owned by dealers...

While driving vechile shakes violently between 35-45 mph. I was informed the right axle needed replacement. There is a recall for 2016 optima axle replacement but Kia says my car doesn’t fall under it even though is the exact issue as the recall.

The contact owns a 2016 Kia Optima. The contact stated while driving on the highway at 65 MPH, the vehicle began to jerk excessively, and the contact was forced to pull over to the side of the road. The check engine warning light was illuminated. The vehicle was towed to a local dealer, where it was diagnosed, and the contact was informed that the fuel injectors and valve cover gasket were faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 112,260.

Was driving going 50mph and all of a sudden with traffic accelerator stopped working. The oil engine and battery light all came on. When I tried jump starting it it began to smoke.

[XXX] 6:30AM: 2016 Kia Optima Ex I was driving on the freeway on my way to work when I lost all acceleration and immediately attempted to get over to the side of the road. Which was pretty [XXX] scary being that it's a busy freeway that early in the morning so everyone is laying on their horn while trying to get out of my way. It was either be stranded in the middle of the freeway or get over as quick as possible. My electronics were all still on however; my whole dashboard went from no "check engine" light to everything that could light up was lit up. I own a OBD2 scanner so I plugged that in and scanned it. I received a code that read "P0014: Exhaust Camshaft Position Timing - Over - Advanced (Bank 1)". I then had my car towed to a mechanic that diagnosed my...

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...

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...

The high voltage battery and the ability to drive or turn on completely

Vehicle Dash Check Engine Light came on 08/31/2023 Code P200A was found. 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.

Pearl white paint peeling in chunks of hood. All four window regulators went out within six months. Transmission had to be replaced Hard shift rear end Motor replaced

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.

2016 Kia Optima was towed to Kia Dealer after it became inoperable; on 10/22/22 diagnostic done and found engine failure. Kia Motors denied claim for repair/replacement. Not sure why not covered under class action settlement, and/or extended warranty, or subsequent technical bulletins regarding Kia's defective engines.

Every 2000 miles I need to put in a quart of oil. When car down shifts to 35mph the oil light flickers. At downshift of 10mph there is a slight shutter and the oil light flickers.

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 car is experiencing excessive oil consumption, engine knocking and shifting delays, grinding or jumping during acceleration, the car jerking on the road.

Despite maintaining the vehicle and replacing the battery, the car will have weird acceleration jumps during highway and city travel. It will also not start properly on occasion where it will idle rough and stall when trying to shift into drive or reverse.

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...

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.

My steering wheel will randomly lock in the middle of road while driving. I have to forcefully turn wheel to be able to pull of off the road meanwhile the there is on coming traffic. I have been told my car is having misfire and an engine knock code P1326 I have also got other codes and was told it could be a factory malfunction.

The contact owns a 2016 Kia Optima. The contact stated while driving approximately 45 MPH, the vehicle stalled. The contact stated that there was no warning light illuminated. The vehicle was taken to the local dealer to be diagnosed. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure and informed the contact that they were unable to assist. The failure mileage was approximately 106,000.

Have do Documents to back that up #2 Engine light coming on, diagnostic testing indicated spark plugs need to be replaced . Had to do this two times with oil on plugs Took it in and they NEVER look at the spark plugs #3 car burning excessive amount of oil anywhere from 1 quart a week to 3 1/2 quarts after driving 600 miles. Took it into the shop for oil consumption testing only to be told that their warranty would not cover it and it needs a new engine. I have a 10 year or 100,000 mile warranty on my car! and at the present time I only have 88496 miles on my car I have documentation to back...

2016 kia Optima will not go in reverse. It will only work in drive. Tried to drive out of my driveway today. 07.22.2021 and the car would not go in reverse. Pulled back in the driveway and will not drive due to safety hazard.

TL* THE CONTACT OWNS A 2016 KIA OPTIMA. THE CONTACT STATED THAT AFTER SHIFTING INTO REVERSE, THE VEHICLE FAILED TO RESPOND. THE CAUSE OF THE FAILURE WAS NOT YET DETERMINED. THE LOCAL DEALER BOWIE KIA LOCATED AT 16620 GOVERNOR BRIDGE RD, BOWIE, MD 20716 AND THE MANUFACTURER WERE NOTIFIED OF THE FAILURE. NO ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS APPROXIMATELY 93,000.

WAS EXITING THE FREEWAY, CAME TO A STOPLIGHT, AND AS CONTINUING WITH DRIVING THE CHECK ENGINE LIGHT STARTS BLINKING AND WAS NOT ABLE TO ACCELERATE, AS IF IT WAS SLIPPING. CAR WOULD NOT GO OVER AROUND 30 MPH UNTIL FEELING THE CAR NOT ABLE TO ACCELERATE AGAIN. I USED A CODE READER AND GOT CODE P1326, WHICH I HAD LOOKED UP AND SAYS IT HAS SOMETHING TO DO WITH A KNOCK SENSOR DETECTION SYSTEM. HAD BRING MY CAR IN TO GET IT CHECKED OUT AND WAS TOLD MY CAR HAD LOW OIL, ABOUT 2 QUARTZ. I DO REGULAR OIL CHANGES THOUGH AND HAD DONE AN OIL CHANGE A FEW WEEKS PRIOR. THE SHOP I WENT TO TOLD ME THERE MAY BE A SERVICE CAMPAIGN FOR THE CAR. WAS TOLD SPECIFIC YEARS HAVE HAD ENGINE PROBLEMS WITH OIL, LOSING OIL ALTHOUGH NO LEAKS OR SIGNS.

CAR LOST ACCELERATION WHILE DRIVING

FROM A STATIONARY POSITION, UPON ACCELERATING THE CAR HESITATES, VIBRATES, FEELS AS IF IT MIGHT STALL BUT DOES NOT STALL. CAR, WITHIN A SECOND OR SO WILL CATCH AND ACCELERATE AS IT SHOULD. DRIVER IS VERY AWARE OF THE VIBRATION HESITATION. THE PASSENGER CAN ALSO FEEL THE HESITATION. SKIPPING SENSATION HAPPENS AT ANY STOPPED LOCATION, AT AN INTERSECTION OR STOP SIGN ETC. I T SEEMS TO HAPPEN ABOUT 75% OF THE TIME. OCCASIONALLY THERE WILL NOT BEEN A HESITATION EXPERIENCE. I HAVE TAKEN IT IN AT LEAST 2 TIMES TO DEALER SERVICE DEPARTMENT AND WAS TOLD THY COULD FIND NOTHING TO ACCOUNT FOR THE PROBLEM AND EVEN SUGGESTED THAT I USE A HIGHER GRADE FUEL. FUEL MILAGE IS GREAT, ALL OTHER DRIVING ASPECTS OF TH KIA ARE PERFECT.

WHEN I TRY TO START MY CAR IT'LL TURN ELECTRICAL COMPONENTS ON BUT NOT MY ENGINE. I HAVE ABSOLUTELY NO POWER STEERING WHEN THIS OCCURS. CAR WILL GO INTO GEAR BUT I CANNOT ACCELERATE. HAPPENS MORE OFTEN THAN NOT.

WHENEVER DECELERATING THE CAR JERKS TERRIBLY HARD ENOUGH THE THROW YOUR HEAD FORWARD. IT FEELS AS IF YOUR HITTING YOUR BREAKS REALLY HARD!

P1326 ENGINE CODE CAME ON WHILE DRIVING 60MPH ON THE INTERSTATE. LUCKILY WAS IN FAR LEFT LANE WHEN ENGINE SHUT OFF AND WAS SAFELY ABLE TO GET OFF FREEWAY TO A NEARBY GAS STATION.

E - C V V T SEAL SEATING ISSUE. MY 2016 KIA OPTIMA IS GIVING AN OBD II ERROR CODE OF P0010 "A" CAMSHAFT POSITION ACTUATOR CIRCUIT. THIS CAUSES REDUCTION IN POWER DURING ACCELERATION, AND ELEVATES ENGINE IDLE SPEEDS TO 1200-1400 RPM. THIS ELEVATION IN ENGINE SPEED CAUSES THE CAR TO TRY TO MOVE FORWARD EVEN WHEN THE BRAKES ARE PRESSED IN STOP AND GO TRAFFIC. IN STOP AND GO TRAFFIC, THIS COULD EASILY LEAD TO VEHICLE CRASHING. THIS, I BELIEVE, SHOULD BE A PART OF RECALL INSTEAD OF A TECHNICAL SERVICE BULLETIN FROM THE MANUFACTURER. HYUNDAI AND KIA USE SAME ENGINE, AND HAS A TSB NUMBER 15-01-022-1, AND KIA HAS A TSB TO CHANGE THE MOTOR PLUG AND ECVVT COVER FOR IT. THEY ARE AWARE OF THIS ISSUE IN THEIR CAR, AND IT SHOULD BE A RECALL. WHEN THE CAR WAS IN MOTION FOR ME THE FIRST TIME THE...

LIMIT BEHIND US. I WAS ABLE TO GET OFF THE INTERSTATE AND CALL ROAD SIDE ASSISTANCE. THEY TOWED THE VEHICLE BACK TO UNIVERSITY KIA IN WACO, TEXAS. WHERE IT CURRENTLY SITS, AWAITING A NEW TRANSMISSION. WE ARE TERRIFIED TO GET BEHIND THE WHEEL OF THIS CAR AGAIN. ALL I AM BEING TOLD IS THAT A NEW TRANSMISSION IS BEING ORDERED AT THIS TIME.
