2015 KIA OPTIMA Power Train Problems

On December 27, 2025, at approximately 150,556 miles, my 2015 Kia Optima Hybrid experienced sudden engine knocking, power loss, and failure while driving at 65 mph on a highway. The vehicle dropped into limp mode and I had to pull off the highway. The car required towing to the dealership as it would not drive safely. Diagnostics revealed a knock sensor error (P1326 code) and failing connecting rod bearings via Bearing Clearance Test, consistent with the known Theta II engine defect (manufacturing debris causing oil starvation and premature bearing wear). This follows earlier symptoms: Intermittent 'Check Hybrid System' warnings in early December 2025 at 148,665 miles (dealership unable to reproduce, but historical codes noted). The Knock Sensor Detection System (KSDS) software update was performed in February 2022 during prior CHS warnings. Despite onset of issues under the 150,000-mile extended warranty limit per the Kia E2 Settlement, Kia denied coverage due...

While driving my 2015 Kia Optima (VIN: [XXX] ) at highway speed, the engine suddenly shut off without any warning lights, alerts, noises, or check-engine indicators. This created a dangerous situation for me and surrounding drivers. The vehicle had passed state inspection only 3 months earlier with no issues. The sudden shutdown is consistent with the known Theta II engine defect investigated by NHTSA. The car is now completely undrivable. Two Kia dealerships refused to assist, claiming that they cannot perform KSDS because the engine is already dead. These reasons directly contradict the Kia Theta II engine settlement terms. This sudden stall is a safety hazard and could have caused a severe crash. I am requesting that NHTSA review this incident as a potential recurrence of the engine-stall defect already documented in Hyundai/Kia vehicles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle experienced sudden loss of power while driving when cylinder 3 completely failed (0 PSI compression). Metal particles found in oil and excessive oil consumption (1 pint/100 miles). KIA dealer diagnosed as piston rings but ignored metal in oil that suggests bearing failure covered under recall campaign. Refused proper diagnostic testing. Vehicle now unsafe to drive with failed cylinder that could cause complete engine seizure while driving. Kia had all recommended services and oil changes since acquired in 11/2016. These service records demonstrate the progression of my vehicle's engine issues, from early oil consumption problems documented by York Auto Care in July 2023 (3 quarts low) to complete cylinder 3 failure with zero compression confirmed by Kia's own diagnostic testing in May 2025. Despite this documented history and Kia's own test results showing catastrophic engine failure, they have denied warranty coverage under their engine campaign that specifically covers bearing-related failures...

My 2015 Kia Optima Hybrid poses a serious safety risk. While driving at highway speeds, the car has randomly shut off multiple times. A "Check Hybrid System" or hybrid battery warning appears on the dashboard, and the vehicle either loses power entirely or switches to electric-only mode and coasts to a stop. This happens without warning, putting my life and the lives of others at risk. I already had the relevant hybrid system recall work completed by a Kia dealer, but the issue persists and the car remains unreliable and unsafe. This appears to be a known issue affecting many 2011–2016 Optima Hybrid vehicles. Kia needs to be held accountable for continuing hybrid system failures that occur post-recall and outside of warranty. This is a dangerous, recurring defect.

Was driving down the highway and all of a sudden the car shut down in the highway lucky cars was not close by. Tried to crank it it would not crank would not take a boost it won’t say anything I had the battery checked at auto zone the battery is really good. The mileage on the Kia optima is 1,900 actual miles it will not crank or move it was very scary I called Kia customer service there wanted to charge me over $400.00 dollars to come get it and take it to the shop so it took me 2 days to find a tow to get it home and it still needs to go to the Kia shop

The contact owns a 2015 Kia Optima. The contact stated that while driving at various speeds, or while at a complete stop, the vehicle would shut off without warning. The vehicle would resume normal operation upon restart of the engine. The vehicle was taken to a dealer for an inspection; however, the dealer was unable to duplicate the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 88,000.

Engine locked in while driving on road No power an won’t start

Driving one day in Dec 2021, and there was a hybrid system warning and vehicle suddenly stopped on the road. Called tow truck. We were unable to put the car in neutral to tow. Had tow truck deliver to dealership for diagnostic and repair. Dealer replaced transmission and stated it was covered under warranty. Finally got vehicle back and warning still pops on dashboard. We’ve taken it back several times and warning randomly appears. Dealership unable to recreate the warning to diagnose. Unable to drive the vehicle over long distances due to safety concerns.

The vehicle has a seized motor within the manufacturers powertrain warranty. They are denying to repair/ replace the motor because they claim a recall was not performed. The NHTSA does not currently show the recall that needed to be performed. The vehicle should still be covered by KIA's powertrain warranty and the dealer is not accepting responsibility.

1. While stepping on the brakes my car has revved up as if I was pressing the gas. So I let my foot off the pedal and pressed the brakes again. This happened 2 times that week. And another time while I was coming to a stop light as I pressed the brakes, my car revved up but didn’t actually make my car speed up. I had to press the brakes again for it to stop. 2. My battery was smoking and I replaced it. 3. My car is consuming oil. The dealership did a series of oil consumption testing due to the exhaust leaving extra carbon residue on my car. They said it was fine but I don’t think they solved the issue.

My car is dragging/hesitant to pick up speed. While on the highway, it takes a while to reach minimal speed. No warning lights are on, but one mechanic advised code, under turbo boost. My steering wheel vibrates at speeds above 40 mph (unsure if it's related to turbo), but no one seems to be able to find the core of the problem for repair, Kia dealership included. I've been trying to seek repair for close to a year, without satisfaction.

The contact owns a 2015 Kia Optima. The contact stated while driving at an undisclosed speed, the brakes and the steering column were inoperable. The contact stated that several unknown warning lights were illuminated. The contact was able to safely pull off to the shoulder of the roadway. The contact stated that the engine started smoking. The vehicle was towed to an independent mechanic. The vehicle was not repaired. The contact stated that in December 2020 and March 2023, recall repairs were completed on the ABS and TCU modules. The manufacturer was made aware of the failure, and a case was filed. The approximate failure mileage was 94,700.

My 2015 Kia Optima EX with 56,462 miles which I am the original owner. On 09/07/2024, my vehicle oil light came on and the vehicle was taken to Weston Kia in Gresham, OR. This vehicle has had regular oil changes every 3,000 miles since purchased performed at Weston Kia. The service department found a leaking oil pressure switch and preformed the repairs totaling $248.60 on 09/08/2023. Per Kia 10yr/100,000 Powertrain warranty for original owner "In the Engine: Cylinder block, cylinder head and all INTERNAL PARTS, timing gear, seals and gaskets, valve cover, flywheel, OIL PUMP, water pump and turbo charger, pg. 6." I believe this part is covered per Kia warranty and the definition of drivetrain "A powertrain is a system inside a vehicle, in a car, a powertrain consists of the engine or motor and its internal components, such as the energy storage system, transmission and driveshaft." After reviewing...

Driving on highway at 65 mph and engine just died with no warning. Almost got hit trying to get off the expressway to the side of road. Had car towed home and checked engine. Engine is seized up completely.

Was driving down the interstate and engine cut off suddenly. Had to coast across several lane to pull over out of traffic. This was very dangerous. Had car towed home. Engine is locked up . Called Kia dealerships near me. Closest one is not accepting any engine replacement appointments at this time and don’t know when they can. Wouldn’t even give me a future appointment. Kia lawsuit website says my vin number is covered for engine replacement but I can’t get a dealer to even look at it.

1.Since 1/17/23 I've had 5 occurrences of the car yanking me to the left as I am turning right. The steering wheel gets stiffed, the dashboard lights come one, car slows down and I have to park the car and turn it off and back on. When I turn it back on, no dashboard lights are on and the everything is back to normal as if nothing ever happened. I have taken the vehicle to the dealership 3 times for a diagnostics and nothing comes up. The vehicles computer is not even tracing the times the dashboard lights have turned on as it shows zero history and that is not the case. I have taken pictures and video of the dashboard lights and have showed the guys at the dealership but since there's no record on the dashboard computer/history, they're not able to determine the problem. 2.My safety has been...

Knock sensor replaced due to engine knocking did not fix the problem the cars engine does not work it julks and pulls really hard engine noise check engine flashing left me stalled on the main highway with my 2 children with no warning the car has engine oil to adequate levels maintenance was up to date

The engine lost power taking off crossing a major roadway, resulting in a stall, vehicle had to be restarted in a panic. The knocking and loss of power put me and my passenger in danger of a side impact from cross traffic. The issue was reproduced by a dealer upon further inspection. The vehicle will be inspected by a service department at certified dealership. No warnings lights or fault warnings appeared related to this issue.

On 3/1/23 on my way home from my which the site was in Perth Amboy, NJ. At the North Somerset rest stop, just exited the I-76 westbound. I lost power around 65 mph. I didn't get any response from my brakes at first and nothing from my accelerator. Upon drifting and praying that I'd make it to the lot out of the main exiting lane. Upon pulling into a spot at the very farthest spot from the building, I noticed my check engine light is flashing. Press my brakes were working. Accelerator was hardly responding. I've worked on my car and my families cars, and cars most of my life. I had my code reader with me. Plugged it in and got the code that I've heard and read about. P1326 knock sensor. Knowing about this about Kia and Hyuandi, I knew my engine was dead. Thank God it didn't...

August 6, 2022 on Kansas Turnpike near El dorado. 2015 Kia Optima LX 74,000 miles. With absolutely NO warning whatsoever revved high then began a knocking sound, then a horrible banging and died. No lights, no alarms. Steering became a problem. We were able to drift to the side of the road as we were already in the right lane. Once completely stopped dash lights came on. We had no idea of any recalls or issues. Engine never recovered and we procured roadside assistance. Waited 4 hours on the side of the turnpike. We have since learned of a class action lawsuit against Kia with this very issue. We are still waiting for an engine replacement/rebuild 15 weeks later!

2015 Kia Optima Hybrid HEV system. Months after purchasing the vehicle two different lights would come on the engine. One is the HEV warning light and the other is a flashing “Turn off engine and check HEV system”. The first time it happened the vehicle turned off. It was towed to Kia, 02/2020. They change some sensor and sent me on my way. 3 weeks later the HEV warning light came on again so it was towed to Kia for the 2nd time, 03/2020. This time they said they could not recreate the issue. A month later the light came on again and again but since the light never stayed on, I kept getting told by Kia that I’d have to take it in when the light stayed on. 01/2021 the light came on again, with the flashing warning and the vehicle turned off, mid-drive. It was towed to a...

For one my car is very sluggish when taking off and shifting gears Jerks badly. MY electrical is messing up on my radio and camera. Sometimes I smell rubber burning. When I have my cruise on it will speed up on its on and jerk when it does and when i press my brakesbto slow down it doesn'twant to slow down unless iash really hard. When taking off from a hill or a dead stop it doesn't want to shift and slags and rattles when it shifts. Bluetooth works sometimes and sometimes it doest it depends on when my backup camera works or not. I bought this car used in June of 2021 with a little over 92000 miles. I know when something doesn't sound right and when something is messed up, there is something wrong with my car. So far I haven't been in an accident but I don't...

In 2020 a message saying “check hybrid system, stop vehicle and turn off engine appeared and the car stopped while I was driving. I brought it to the Kia Dealership and they “fixed the problem”. On Tuesday May 31st I was driving home on the expressway and my car stopped. I luckily was able to pull off to the side and then the same message popped up and the car would not drive anymore. I have had 5 recalls with this car and it is only 7 years old.

Engine/motor failed which disabled the car on highway. Traveling on 3/4 lane highway with heavy traffic. Safety was risked due to almost being hit from behind and cars swerving out the way. Problem was assessed and thought to be repaired but occurred again causing more possible damage to engine. Warning lamp illuminated seconds before the car shut off which was not enough time to pull over safely. Car had to be towed off highway.

1. The O2 Sensor malfunctioned causing check engine light to come on. The Catalytic Converter failed or malfunctioned, an it is available for inspection upon request. 1wk after replacement of O2 Sensor installment, check engine light illuminated once again. [Official diagnosis was the catalytic converter was faulty but no mention of replacing 02 once catalytic converter was fixed]. 2. My safety as well as my children's safety was put at risk because there was and still is (even after repairs made from dealership where car was purchased) an issue with broken exhaust system and leak. A broken exhaust system poses extreme danger because it releases carbon monoxide (CO)- an odorless ,tasteless, highly toxic gas, which can travel in passenger area and cause carbon monoxide poisoning. Overexposure to this odorless and colorless gas can cause death. Even in mild cases of exposure to CO can cause headaches, dizziness, nausea and fatigue....

VEHICLE HAD SERVICE LIGHT ON FOR ENGINE. I TOOK IT TO THE DEALERSHIP AND THEY SAID IT'S OK TO DRIVE TODAY UNTIL THEY SERVICE IN THE MORNING. THEY HAD A SENSOR SHOW FOR THE HEUC. I DROVE 10 MILES APPROXIMATELY HALF ON FREEWAY AND AT FULL 65MPH THE CAR MADE A VERY LOUD ELECTRICAL NOISE AND LOST FULL DRIVE POWER. I WAS ABLE TO SAFELY AVOID GETTING HIT AT FULL FREEWAY SPEEDS IN RUSH HOUR AND ABLE TO GET ON SHOULDER AND EXIT RAMP. CAR TURNED BACK ON AND WOULD NOT EXCEED 15MPH AT THE LIGHT AND WAS TOWED TODAY DIRECTLY TO THE DEALERSHIP FOR FURTHER INQUIRY.

MY 16 YEAR OLD SON SAVED HIS MONEY (SINCE 13 YEARS OLD) AND PURCHASED BACK IN OCTOBER 2019 THE CAR USED FROM A DEALER WITH 79546 MILES ON THE CAR. ON FEBRUARY 18, 2020 ON HIS DRIVE HOME FROM SCHOOL HE NOTICED A LOUD KNOCKING NOISE. HE WAS NOT SURE WHERE IT WAS COMING FROM, NO WARNING LIGHTS CAME ON WHATSOEVER. HE DROVE THE CAR STRAIGHT HOME. MY HUSBAND CHECKED THE OIL AND THE DIP STICK HAD NO OIL ON IT. THE CAR AT THIS TIME ONLY HAD 82794, IT'S LAST OIL CHANGE BACK WHEN WE PURCHASED IT IN OCTOBER AT 79546 MILES. HOW DOES A CAR BURN THROUGH SYNTHETIC OIL IN A LITTLE OVER 3K MILES AND 5 MONTHS OF DRIVING. WE HAD THE CAR TOWED TO AN INDEPENDENT AUTO REPAIR SHOP WHICH STATED THE ENGINE FAILED AND NEEDED TO BE REPLACED DUE TO BEARING FAILURE. AFTER DOING A...

WHEN TAKING OFF AT A STOP LIGHT OR GETTING ONTO THE INTERSTATE (BASICALLY WHEN ACCELERATING) THE CAR FEELS LIKE IT HAS NO POWER. YOU CAN HEAR A WEIRD NOISE AND SOMETIMES YOU WILL SMELL BURNT OIL OR SOMETHING BURNT. ALSO, I HAD A RECENT OIL CHANGE AND WITHIN THE MONTH I HAD TO ADD OIL AGAIN. THERE IS NO SIGN ON MY DRIVEWAY THAT THERE IS A LEAK. PLEASE LOOK INTO THIS AS THERE ARE MULTIPLE PEOPLE WITH THE SAME ISSUES.

MY VEHICLE IS AMONG THE VEHICLES REGISTERED/QUALIFYING FOR A RECALL. MY DEALER WAS TO HAVE REPLACED MY ENTIRE ENGINE DURING THE FIRST RECALL MY VEHICLE RECEIVED. WITHIN A WEEK/SOME 5 DAYS OR SO MY CHECK ENGINE LIGHT WAS BACK ON. TAKING THE CAR BACK TO MY DEALER, IT WAS SUGGESTED THAT I PAY $145 JUST FOR THEM TO DO A DIAGNOSTIC ON THE/MY VEHICLE THEY HAD JUST SERVICED.

I STARTED HAVING ISSUES WITH MY VEHICLE IN OCTOBER 2019, I TRIED TO REACH OUT TO KIA DEALERSHIPS, WITH NO HELP. I KEPT BEING TOLD THERE WERE NO RECALLS ON MY CAR AND THAT I DID NOT NEED TO BE CONCERNED. MY CAR FINALLY STOPPED WORKING, IT JUST WOULD NOT DRIVE. IT WAS JUMPING FROM 0-7000 RPMS AND THEN FLYING FORWARD BEFORE IT STOPPED WORKING ALTOGETHER. AROUND THE MOMENT IT STOPPED DRIVING IT STARTED SMOKING AND I JUST PULLED OVER AND TURNED IT OFF AND THEN IT WOULDN'T EVEN GO INTO NEUTRAL FOR A TOW TRUCK. I PLACED A BRAND NEW TRANSMISSION INTO MY CAR EVEN WHILE MAKING A CAR PAYMENT ON IT ON NOVEMBER 23RD 2019, IT IS NOW DECEMBER 11, 2019 AND I HAVE ONLY DRIVEN IT 302 MILES AND I AM HAVING THE SAME ISSUES ON IT. WHEN I CALL KIA I AM TOLD THAT THERE ISN'T...

MY BRAKES AND TRACTION LIGHTS COMES ON RANDOMLY. IT STARTED HAPPENING A YEAR AGO. IT HAS HAPPENED ABOUT 5 TIMES SINCE LAST YEAR. IT HAPPENS SOMETIMES WHILE I'M DRIVING, IT JUST COMES ON AND SOMETIMES WHEN I GET IN AND START THE CAR THEY COME ON.

SOUNDS LIKE PIECES OF METAL WAS LEFT IN THE ENGINE DURING THE TIME OF MANUFACTURING AND WAS NEVER TAKEN OUT ,THE VEHICLE WAS STILL RUNNING, I DECIDED TO TAKE IT TO GET CHECKED , THE DEVICE AT KIA OF ESSINGTON OF PHILADELPHIA SAID IT WAS A GRINDING SOUND ON THE BOTTOM END OF THE ENGINE

TOOK MY CAR INTO THE DEALERSHIP ( ATLANTA WEST KIA, DOUGLASVILLE, GA) FOR AN OIL CHANGE, TIRE ROTATION, ETC. I WAS NOTIFIED WHEN I CHECKED IN THAT THERE WAS A COMPUTER RECALL FOR AN UPGRADE OF THE COMPUTER/ELECTRONIC SYSTEM. THEY INFORMED ME THAT THEY WOULD DO THAT WHILE PERFORMING THE OTHER SERVICE WORK. 3 WEEKS AFTER THE OIL CHANGE I WAS DRIVING ON THE INTERSTATE THE CAR SUDDDENLY LOST POWER AFTER A BIG PUFF OF WHITE SMOKE AND LOUD NOISE. I WORKED MY WAY OVER TO THE NEST EXIT AND PROCEEDED TO TURN AROUND TO GO BACK HOME. NO WARNING/ENGINE/OIL LIGHTS CAME ON DURING THIS TIME. I CALLED THE DEALERSHIP AND NEVER RETURNED MY CALL, WITH NO RESULTS. WE CHECKED THE OIL THE CAR WAS 3 QUARTS LOW. CONTINUE TO NOTIFY THE DEALER TO NO AVAIL.

I HAVE NEVER HAD ANY PROBLEMS WITH MY VEHICLE SINCE THE DAY I BOUGHT IT BRAND NEW. I MAKE SURE TO GET REGULAR MAINTENANCE AND I AM NOT A HARSH DRIVER. I WAS DRIVING ABOUT 50 MPH ON A 2 LANE ROAD. THE LIGHT AHEAD TURNED YELLOW AND I SLOWED DOWN TO STOP. ONCE MY VEHICLE CAME TO A STOP AT THE RED LIGHT, IT MADE A WEIRD NOISE LIKE IT WAS GOING TO CUT OFF BUT DIDN'T. THE LIGHT TURNED GREEN AND I BEGAN TO PRESS THE GAS AND IT SEEMED AS IF IT WAS STALLING AND WOULD NOT ACCELERATE AS QUICKLY. THE ENGINE LIGHT, BATTERY LIGHT AND OIL LIGHT POPPED ON SO I PULLED OVER IMMEDIATELY, TURNED MY CAR OFF AND WAITED ABOUT 5 MINUTES. I CRANK THE CAR BACK UP AND THE ONLY LIGHT REMAINING ON WAS THE ENGINE LIGHT AND MY CAR STARTED MAKING A KNOCKING...

MY VEHICLE IS RANDOMLY DISPLAYING 'GOODBYE' ON THE DASHBOARD AND IS SHUTTING OFF WHILE DRIVING. THIS STARTED FROM NOWHERE WITH NO WARNING LIGHTS OR WARNING SIGNALS. I'VE ONLY HAD THIS VEHICLE FOR 6 MONTHS AND IT HAS LESS THAT 30,000 MILES ON IT. THERE ARE NO OPEN RECALLS ON THE VEHICLE, HOWEVER I'LL READ ABOUT SIMILAR ISSUE WITH THE SAME MAKE AND MODEL. I MAINTAIN MY VEHICLE ACCORDING TO HOW KIA SUGGESTS. THIS IS EXTREMELY DANGEROUS AS I AM SOMETIMES HEADING TO WORK, GOING ABOUT 65 MILES OR MORE OR THE HIGHWAY AND THE CAR JUST STOPS. IT IS NOW BEGINNING TO SHUT OFF IMMEDIATELY AFTER CRANKING, AND A NOISE IS COMING FROM UNDER THE HOOD, WHICH SOUNDS LIKE METAL IN THE ENGINE. I HAVE REFRAINED FROM DRIVING THE VEHICLE COMPLETELY, DUE TO FEAR OR LOSS OF LIFE. THE SUDDEN STOPPING OF THE VEHICLE HAS HAPPENED WHILE I WAS DRIVING...

I HAVE A 2015 KIA OPTIMA WITH 24,300 MILES I PURCHASE MY CAR BRAND NEW FROM SOUTHWEST KIA . I TOOK MY CAR IN FOR SERVICE BECAUSE I HAD JUST RECENTLY HAD OIL CHANGE AT WALMART 700 MILES LATER MY OIL LIGHT STARTED APPEARING. I TOOK IT TO KIA BECAUSE RECENTLY HAVING OIL CHANGE AND CAR WAS NO LONGER REGISTERING OIL. KIA WENT ON TO TELL VERY LITTLE OIL WAS IN MY CAR I INFORMED THEM THAT I HAD JUST HAD OIL CHANGED 700 MILES AGO. SO FROM THERE DEALERSHIP DID OIL CHANGE. I WAS BACK AT THE DEALERSHIP WEEK LATER WITH SAME ISSUE. SERVICE STATED THAT HE FOUND SLUDGE AND I STATED THAT I HAVE HELD UP MY END OF THE DEAL WITH OIL CHANGES AS WELL AS I PROVIDED MY RECEIPT OR OIL CHANGES. DEALERSHIP IS NOT WILLING TO HOLD UP THERE 100,000 POWER TRAIN WARRANTY STATING THAT...

TAKATA RECALL: THE TIRE LOW LIGHT ON HE DASH IS ALWAYS ON NO MATTER WHAT I DO. I HAVE ALWAYS HAD MY TIRES CHANGED FROM THE DEALER NEVER FROM A THIRD PARTY. THIS IS INCONVENIENT FOR ME BECAUSE THIS IS THE IDENTIFICATION FOR A LOW TIRE. SO ANYTIME I SUSPECT A LOW TIRE I HAVE TO STOP MY VEHICLE WHERE EVER I MAY BE GET OUT AND WALK AROUND THE VEHICLE TO MANUALLY TEST THE PRESSURE IN MY VEHICLES TIRES..

RECENTLY MY TRANSMISSION CASE CRACKED AS IT PASSED OVER A MANHOLE COVER ON A STREET BEING RESURFACED. MY DEALERS SERVICE DEPARTMENT SAID THIS HAS HAPPENED A LOT. I WAITED NINE WEEKS FOR THE PART TO COME IN. I LOST $1,100.00ON CAR RENTALS. CAR'S TRANSMISSION CASE IS TOO LOW TO THE GROUND.

WHEN I AM DRIVING MY 2010 KIA OPTIMA AND GO TO SLOW DOWN AT 20 MPH (ONLY AT 20 MPH AND ONLY WHEN SLOWING DOWN) MY CAR DOES A JERK OR LURCHING MOTION, WITH A HARD DOWN SHIFT TO 1ST GEAR.THIS HAPPENS NO MATTER WHERE IM DRIVING. FROM WHAT IVE BEEN TOLD THERES A TRANSMISSION UPDATE SOFTWARE WHICH WHEN UPDATED. AFTER BEING UPDATED THE DEALER HAS TO RSET/LEAR THE RELEARN PROCEDURE. BOTH STEPS MUST BE DONE TO ELIMINATE THE LURCHING/JERKING. I FEEL THERE SHOULD BE A RECALL FOR THIS PROBLEM.

TL* THE CONTACT OWNS A 2015 KIA OPTIMA. THE CONTACT STATED THAT WHILE IN PARK WITH THE VEHICLE TURNED OFF, THE VEHICLE ROLLED AWAY INTO A LAKE. AFTER RETRIEVING THE VEHICLE FROM THE LAKE, THE CONTACT NOTICED THAT THE GEAR SHIFTER WAS NO LONGER SHIFTED COMPLETELY INTO THE PARK POSITION. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 1,680.
