2017 Kia Optima Complaint Log

While driving on the freeway and NO vehicles around me, the sunroof shattered, I am reaching out to consumers to see if they have encountered the same problem. As I reached out to KIA consumers affairs and after waiting 2 months I was told to reported it to my insurance and they will cover my deductible but it will take 90 days for my deductible to be processed and issued to me. A total of 5 months to wait for my sunroof to be fixed is unacceptable. FYI - KIA Dept. of consumers affairs (800) 333-4542 you will be on hold for hours before someone can help you, so annoying… Any suggestions or help will be greatly appreciate.

Excessive oil consumption started at 61,000 miles, causing engine misfires and dangerous power loss on the road. Engine codes 1326 and P0304 were frequent. Despite numerous services, including sensor replacements, spark plugs and oil top-offs, the problem worsened. At 97,769 miles, the dealer said a full engine replacement is needed along with other pertinent repairs related to the engine are needed. The situation was life-threatening each time as they occurred while driving and I now no working vehicle after my husband's recent death. Kia dealerships acknowledged the defect but refused to replace the engine and advised that Kia Corporate was refusing, although no claim information was ever provided that they indeed contacted the corporate office. I am seeking NHTSA support in holding Kia accountable.

After driving for more than 5 or so minutes I begin to smell a burning smell. I’ve had my brakes inspected, my oil changed and even took it to the dealership however it continues to keep happening

I was driving on the highway when my check engine light came on flashing the car jersey almost to a stop and I had to pull over. I cut the car off and sat then turned it back on. The check engine light was still flashing and I put my flashers on and was unable to go over 60 mph. I drove slowly to an autozone and a code was pulled p1326. I looked it up and it undeliverable due to the knock sensor issue.

Car overheated without any forewarning or indication lights being displayed. Causing hydraulic and engine to fail. Kia is not taking responsibility for the rod bearings causing the overheat. They are saying at the dealership my car was not part of this recall. They refuse to fix it and want me to pay for the new engine myself. Three mechanics have already stated that the hydraulic can be caused by the rod bearings. They are denying the claim

EXCESSIVE oil consumption. More than 1 quart every 1,000 miles. I am having to change my spark plugs about every 3 months to keep this car going. I've been to Kia twice and spent thousands of dollars. It has fixed nothing.

The Engine burns oil at a rate higher than the recommended oil change interval. I have had the dealer perform multiple consumption tests. The car passed all three even though it burns around a quart every 1000 miles. I had them clean the combustion chamber and paid for the costs myself but that did not resolve the issue. This seems be a known defect in the engine and is causing me a lot of problems monthly. A recall needs to be issued to fix this problem.

Since I purchased the car I have a had a issue with my vehicle misfiring. We purchased the car in 2018 and a few months in I had to bring the car in for a rattle and shaking while I was driving. It would give me a warning lamp stating that a “possible engine control issue had been found”. Since then I have taken the car in for the same issue three different time. Including the misfire and coil pack and spark plug replacement that I just had to pay nearly 600 for at the dealership. I have had this issue occur multiple time since we purchased the car and while driving on the freeway nearly putting my life at risk. This is an issue that needs to be addressed.

This has happened 3 times driving car almost comes to a complete stop. Acceleration dropped down to 20 MPH. Was told it was a knock sensor replace in March in May did it again . Replaced it against the very next day it did it again. Went online and said it was a recall but nothing is showing up here . I will contact Kia in the morning we could have been killed this happened in the expressway

Excessive Oil Consumption: Could cause Engine failure, Engine Seizure due to lack of oil. I have a 2017 Optima with Excessive Oil Consumption issue. I noticed the car is consuming excessive oil, for the third time. Many people had reported this issue, leaving customers with expensive repairs. This issue could cause Engine failure, Engine Seizure due to lack of oil. I took the vehicle to the dealer, (Kia) recommended additional services and kept the vehicle overnight for testing. These additional services were outside the normal maintenance interval and are expensive. Quick History: -As of 12/26/2023 Vehicle was dropped off due to excessive oil consumption, this time before the service interval was due. -2017 Optima/ 83,200 Mi -All Oil changes and scheduled maintenance performance at normal interval, sometimes sooner due to the Excessive oil consumption. -Car is for personal use/ normal driving - No Leaks detected in the Car

March 2022, (approximately 72,000 miles)while driving to work my car shut off. I was in drive at a red light. Noticeable decreased acceleration and vibration. Took it to the dealership for routine oil change and mentioned incident. Technician was not able to find cause. Ok so be it. Now May at a little over 73,000 miles multiple lights began to illuminate and flash. Still with decreased acceleration it was noticed on a Friday morning on my way to work: 1. Oil light flashed on and off for approximately 2 minutes. 2. Air bag light stays on 3. Electronic Stability Control light stays on I scheduled an appointment for the next day. Took it into nearest Kia dealership. I was informed that my engine had no oil in it. The electrical board that signals my airbags and power steering is “malfunctioning” and would need to be replaced. I was also told that since I just went for an oil change and was not due for another 3-4,000 miles maybe the “engine absorbed the oil as there are no visible leaks” I am set to return to Kia at the 1,000 mile mark to check oil levels to see if the oil is gone again. On my way to work again, on I-75 I felt extreme unsteadiness and loss of road grip with steering. Like I was loosing co trio of the vehicle while traveling at 55 miles an hour. As the original owner of this vehicle, with regular routine maintenance this is extremely concerning. I worry every day that my car will fail me and injure mine, my kids and others lives. I really hope this is looked into as a safety issue.

I have been driving at night going 70 mph on major rural freeway, as well as 55 mph on a two lane rural country road when the auto headights went completely dark, including all the interior lights. I could see nothing in the dark at those speeds ... not even the road. The first time this happened, I panicked because I could not see the road. I slammed on the brakes. I turned the auto light switch from auto to off and then turned to regular on. The headlights and interiors lights came back on. The second time this happened, I was going 70 mph on a rural highway. I immediately took my foot off the petal and turned the auto light to off and back on to regular on. I told the Kia Dealership and they said I would need to pay $138 to have them investigate the problem. The Service Center said they have heard of the problem before but were very vague. This is a MAJOR SECURITY TRANSPORTATION RISK.

I was driving down hwy 60 in Lake Wales, Florida, passing a car at 70 mph. While passing, all of the alerts and indicators came on my dash, and I lost the ability to accelerate. To get off the road without getting rear-ended, I drove off into the grass in the median and stopped on the paved crossover. When I stopped the car, it shook and the engine died. The "hybrid warning/turn engine off" light came on in the middle of the display, so I turned off the car. I waited a few minutes and turned the car back on, no alerts were showing, but when I shifted into drive, the hybrid warning came back on, and all the lights/alerts on the dash were lit. The car had to be towed to the dealership. On Tuesday, Feb. 15, the dealership told me they performed a software update and the car was running again, but they wanted to keep it another night. On Wed., Feb. 16, the dealership called again to tell me the same situation that occurred on 2/14 happened again. They told me the codes that were given were related to the transmission. They said the transmission had to be replaced. The car is 5 years old. I asked about the transmission control module, and they said the entire transmission had to be replaced in order to replace the TCM. I took the car in after a recall notice was received in January 2022. I was told the recall only required an inspection, so there was no software update at that time. The tech told me that the original software update was done in April 2021. We received a 2nd recall notice this week saying the prior software update had an error and needed to be updated. The tech told me this is the update they did on 2/15. The dealership is telling me I need a new transmission. I'm having a hard time trusting anyone at the dealership.

The contact owns a 2017 Kia Optima. The contact stated while driving 50 MPH, while slowing down the brake pedal was depressed and would engage however, after several seconds the brake would disengage and the vehicle would roll forward. The contact was able to safely stop and noticed a knocking sound coming from the rear area in the trunk as the vehicle came to a stop. The contact stated no warning light was illuminated. The contact took the vehicle to an independent mechanic, where it was diagnosed however, the mechanic found no failure. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 83,000.

Engine is consuming excessive oil. That could cause internal parts of the engine to wear faster because of less lubrication and could lead to an engine failure while driving, which could lead to engine stopping and loss of propulsion which could cause an accident. The car went through a oil consumption test with a Kia dealership and failed by consuming more than 1 qt of oil in a 1000 miles interval. The Kia dealership proceeded to do a combustion chamber cleaning procedure and re-did oil consumption test and it failed again. They also had requested service record which where provided. Even though Kia has a service bulletin on that matter, the service advisor at the Kia dealership said that the manufacturer declined the claim. Right now I’m constantly refilling oil in the engine which is also an additional expense. The first time I noticed the issue was in February, 2022 when the low oil pressure alert came on.

The contact owns a 2017 Kia Optima. The contact stated that while driving at 65 MPH, the vehicle entered limp mode as several warning lights illuminated on the instrument panel. Due to the failure, the contact had the vehicle towed to the dealer and was informed that his vehicle was under NHTSA Campaign Number: 21V844000 (Engine), which they linked to his failure. Despite the recall repair, the failure occurred on two additional occasions. The vehicle was taken back to the dealer where an additional software update was performed; however, the failure continued. The manufacturer was notified about the failure and sent an investigator to inspect the vehicle. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was approximately 112,000.

Oil consumption in my vehicle is well above 1 qt per 1000 miles. This is a known problem but Kia engines and Kia doesn't take responsibility for it. The oil light never comes on and the car runs out of oil every 1500 miles. It's not leaking, it's being consumed. Kia does not see it as a problem, even though there are so many reports. Please expand the recall for 2017 Kia's.

My air conditioner all of a sudden went out. No air would blow. Took it to Kia and it turns out that a fuse box blew on the main wiring harness, evidenced by burn marks on the bottom which then blew out my fan motor. Seems that Kia has had a lot of faulty wiring harnesses and it could have definetly caused a fire and is a safety hazard. My car is out of warranty by 8k miles and they are trying to make me pay for something that I believe is a defect as they said themselves that they cant even determine the cause as this is not normal wear and tear nor something I could have caused. I cannot afford to pay for this and I do believe that Kia needs to make this right. Because everything electrical plugs into this one wiring harness, they have to replace the whole thing costing over $3600. There was no warnings or lights that came on. I do believe that this also messed with the airbag sensor in the passenger seat as well. This is not right for consumers to have to worry about this. This is a 2017 car... it should not be failing.

I had got on the freeway when I got to my destination I got off the freeway and was waiting for the green light my car started shakeing and shut off. I was able to turn it back on

Several weeks ago, we had trouble opening and closing the trunk of our 2017 KIA Optima. Then a few weeks ago, the trunk of our KIA Optima closed and would not open at all. Because of the pandemic, we didn't contact KIA. But today, 16 Dec. 2021, as my wife was driving north in heavy traffic on US Highway 25 in Albuquerque, NM, the trunk suddenly opened and blocked her view of the cars behind her. Luckily she was in the right lane and was able to exit the highway. Otherwise there might have been a serious accident. We bought the car in 2017 from Fiesta KIA in Albuquerque, NM (505-999-2745). They have been unresponsive.

During the week of November 14th, 2021, I noticed my vehicle begin to noticeably vibrate and generate an unfamiliar sound near the engine compartment. The vibration and sound was accompanied by a "check engine" light illuminating. I immediately scheduled an appointment at my local dealership and was provided a date of November 29, 2021. On November 29, 2021, I dropped off my vehicle at the dealership and learned of NHTSA Recall Number "21V844." The service representative and his technician believe the vibration and sound are a result of the recall. To date, my vehicle remains at the dealership and the matter is unresolved. The service representative has advised me that Techline / KIA Corp. is determining whether my vehicle's engine issue is due to the recall or not. It has been two weeks that the vehicle has been at the service center. As per the recall notice I received in the mail, the inspection for the recall should have been completed in a matter of hours. I reasonably believe that Techline / KIA Corp is searching for an excuse to not remedy my vehicle's engine issue, and are jeopardizing the safety of myself and my family. I have a newborn and kindergartener that I have in the car daily and am concern for their safety if the engine issue does not get fixed. I am a military veteran and active police officer. I appreciate any assistance you may provide and thank you in advance.

My Kia Optima was burning three (3) quarts of oil for every 1,200 miles driven. I brought the vehicle to Willowbrook Kia and they stated that they would need to do an oil consumption test. After the 1st test, it showed that I burned 3 quarts after 1,200 miles driven. Kia completed an intake carbon test and had me drive it for another 1,000 miles. After the 2nd test, it showed that I burned 1.5 quarts of oil after 1,000 miles. Willowbrook Kia stated that the engine needed to be replaced and it will be under warranty. They rented me a car which they paid for and it took me to call after 1 week in a half and they stated that the vehicle is not covered under warranty as I am the 2nd owner of the vehicle. The gentleman (Vic) at Kia told me the only way to get Kia to replace the engine is to drive it until their is no oil and the engine seizes. I explained to him that I drive on the expressway everyday and that is kind of like an accident waiting to happen. No accident has happened as of yet, but thought I would at least try and send a complaint your way. If there is nothing that can be done, I completely understand, but was trying to avoid a possible accident in the future.

The trunk won't close.

The vehicle automatically turns the headlights off automatically (at night). While driving and not touching the multi function switch, the vehicle indicate that the headlights were switched manually to the "off" position from the "auto" position on the multi function switch. This happens randomly at random intervals and most noticeable at night when the car is driving and the lights are turned off and is not reproducible on demand. The safety of both myself and the other vehicles around me are put at risk if my headlights cannot turn on or turn off by themselves at night while operating the vehicle. I went to the dealer, and they told me that even though the car is under warranty since the problem cannot be reproduced I would need to pay a $175 diagnostic fee, the dealer told me that Kia will charge them if they can't prove that the multi functional switch is defective. I contacted Kia customer service, they opened a claim, but did confirm that if the issue is not re-creatable on demand the dealer can charge a fee and there isn't anything they can do to waive that. They told me since it's a safety issue they could escalate the issue, so I agreed to escalate it. Then I never heard back after that. The lcd in the control cluster indicated that the lights were turned off (even though the switch was physically not touched and remained in the "auto" position for the lights). Other Kia Optima owners are experiencing this issue as seen here: https://www.optimaforums.com/threads/headlights-turn-off-automatically-at-night.169987/

Unknown … Right in the moment I started the car. My car turned on the check engine light and it started a fault as if it wanted to turn off, it shakes and the engine works without power. Since that moment it’s doing it constantly.

Large Oil consumption (1qt a week). No warning lights, experiencing loss of power, hesitation on acceleration, oil covering the motor with no signs of leaks underneath the car on the streets. Oil puddling up on the top of the valve cover near the plugs but unable to locate the source. Gaskets and hoses checked and all are in good condition. 125,000 miles.

The contact owns a 2017 Kia Optima. The contact stated that oil was leaking from the vehicle onto the driveway of her home. The vehicle was taken to the dealer, and the mechanic stated that the spark plugs needed to be replaced. The sparks plugs were replaced but the failure persisted. On another occasion, the contact noticed that oil was leaking from under the vehicle again, and the vehicle was taken to the dealer to be diagnosed. The contact was informed that there was oil cylinder #3 spark plug. The spark plug and PCV valve was replaced; however, the failure recurred. The vehicle was taken back to the dealer and the contact was informed that the engine needed to be replaced. The vehicle was not replaced. The manufacturer was contacted and stated that the contact would receive a call back. The failure mileage was 93,226.

The contact owns a 2017 Kia Optima. The contact stated that while driving at approximately 70 MPH, the speed decelerated independently while the check engine warning light illuminated. The vehicle was taken to the dealer where it was diagnosed that the accelerator pedal needed to be repaired. The vehicle was repaired however, the failure persisted. The vehicle was taken back to the dealer where they informed the contact there was an unknown software update. The vehicle was repaired but the failure recurred. The vehicle was taken back to the dealer where it was diagnosed that the knock sensor software needed to be updated. The vehicle was repaired but two days later the failure recurred. The vehicle was taken back to the dealer where it was diagnosed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 70,000.

When driving above 30 mph if you apply light brake pressure to the brake pedal and then allow the vehicle to slow down without applying additional force the ABS will activate when the speed drops to around 20 miles per hour. At that point if you release the brake and reapply them they will operate without issue. If on the other hand you hold the force or apply more force the ABS activation continues the brake pedal gets hard and it feels lie the vehicle is not going to stop. As an employee of Kia America I cannot provide any documentation. That said you should have full access to all the details via the TREAD ACT and I would encourage you to investigate it. Please also note I was able to duplicate this issue in 3 other like vehicles and feel this issue could hurt or kill someone.

The contact owns a 2017 Kia Optima. The contact stated while stationary at a traffic light, while depressing the accelerator pedal, the vehicle hesitated. The check engine warning light was illuminated. The contact was able to continue driving to her residence. The contact took the vehicle to an independent mechanic and was informed that the engine knock sensor needed to be replaced. The contact called the local dealer and made them aware of the failure. The vehicle was not repaired. Upon investigation, the contact associated the failure with NHTSA Campaign Number: 18V907000 (Fuel System, Gasoline, Engine) however, the VIN was not included. The manufacturer had been informed of the failure. The failure mileage was approximately 68,000.

My 2017 Kia Optima Hybrid began losing oil rapidly (more than 1 quart a week), and then knocking. There was never a warning light or an engine light. The mechanic at Kirby Kia (the dealership) confirmed engine knocking in the lower pistons. Kia will not honor the 100,000 mile drive train warranty because I am the second owner, and there is no recall on the hybrid engine. However, it's irrelevant that they won't cover the cost of the engine since they are not making engines available to anyone outside of the recall, so I cannot fix my car. I'm a little confused on why this engine is withheld for the recall, but mine is not recalled.

The contact owns a 2017 Kia Optima. The contact stated after the oil was changed at 1,200 miles, the vehicle stalled and there was an excessive oil consumption failure. The contact replaced the oil more times than the manufacturer recommended interval. The oil warning light was illuminated. The vehicle was taken to an independent mechanic and the contact was informed of an excessive oil consumption failure with the Hybrid models only. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 70,000.

ENGINE HAS TOO MUCH OIL CONSUMPTION , WENT TO DO MY OIL CHANGE 200 MILES BEFORE IT WAS DUE AND THE AUTOMOTIVE PLACE TOLD ME THERE WAS NO OIL ON MY DRIP STICK. ALSO HAVE A RATTLING NOISE IN MY ENGINE WHEN I ACCELERATE. NOISE HAS BEEN HAPPENING FOR A FEW MONTHS BUT THEY CAN'T SEEM TO FIND A PROBLEM.

THE WIRING HARNESS WAS REPLACED IN MY 2017 KIA OPTIMA IN 2019 AT APPROXIMATELY 45,000 MILES. KIA REPLACED MY ENGINE JANUARY 2020 BECAUSE IT WAS CONSUMING LARGE AMOUNTS OF OIL. I JUST GOT MY CAR BACK IN JANUARY 28, 2021 WITH A SUPPOSEDLY NEW ENGINE. ON MARCH 3, 2021, MY CAR CAUGHT FIRE WHILE PULLING OUT OF MY NEIGHBORHOOD ACTUALLY DRIVING DOWN THE STREET. SMOKE AND FLAMES WERE COMING OUT FROM UNDERNEATH THE HOOD THE OF THE CAR. THE ENTIRE FRONT END OF THE CAR BURNED. THANKFULLY, THE FIRE DEPARTMENT GOT THE FIRE OUT AND NO ONE WAS INJURED.

THE WIRING IN THESE CARS ARE COATED WITH SOMETHING THAT SMALL RODENTS LIKE TO EAT THEY CHEW THROUGH THE TAPE THEN THEN WIRING. CAUSING HYBRID ENGINE NOT TO WORK LITES COME. LUCKLY NO FIRE YET. DEALER SAY SORRY THAT WILL BE $ THE CARS WIRING HYBRID PART . RODENTS LIKE TO EAT IT KIA HAS COATING ON IT THAT ATTRACTS THEM THEN IT COSTS YOU THOUSANDS OF DOLLARS TO FIX THEIR PROBLEM CAUSE IT'S NOT COVERED BY THEM. LUCKLY THE CAR DID NOT CAUGHT ON FIRE YET.

THE HEADLIGHTS WILL GO OFF NO MATTER IF THE SWITCH IS ON AUTO OR NORMAL ON. THE LIGHTS CUT OFF WHILE DRIVING, IT HAPPENS ON THE STREET, HIGHWAY, AND EVEN IF THE CAR ISN'T MOVING. IT STARTED ABOUT A MONTH AGO. THERE HASN'T BEEN ANY DAMAGE OR WRECKS TO MY CAR.

My car is consuming major oil. I am having to put at minimum 3 to 4 quarts of oil every 3 days. I am having major loss of power. My car has oil fouled far too many spark plugs. In the last 3 months, I have had to replace the spark plugs three separate times. Within the last 3 weeks I have replaced the following: 1. Ignition Coils 2. Valve Cover Gasket 3. PCV Valve 4. 2 separate sets of spark plugs and 1 singular spark plug for Cylinder #4. My car is having a major oil consumption problem and the performance has been severely affected.

TL* THE CONTACT OWNS A 2017 KIA OPTIMA. THE CONTACT STATED THAT THE SUN ROOF EXPLODED WITHOUT IMPACT WHILE PARKED IN THE GARAGE. THE CONTACT STATED THAT WHILE IN THE HOUSE SHE HEARD AN ABNORMALLY LOUD BOOMING SOUND. THE VEHICLE WAS NOT TAKEN TO A DEALER OR AN INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 37,300.

On November 16, 2020, Lucy Robinson was driving her 2017 Kia Optima when she started seeing smoke. She pulled into a gas station and the engine was on fire. The fire department extinguished the fire. A cause and origin was conducted and it was found that the fire originated within the engine compartment. The fire was caused by the release of heated oil coming from the leaking PCV located at the top portion of the valve cover.

KIA OPTIMA 2017 HYBRID. 26K MILEAGE AND AUTOMATIC TRANSMISSION BECOME VERY CLUNKY, CAR JERKS WHEN SHIFTING ON ANY GEAR. NOT STABLE DRIVING, STRANGE NOISES UNDER THE HOOD ESPECIALLY WHEN VEHICLE GOES UPHILL AND EVEN ON STRAIGHT ROAD CAR TWITCHES. NO OIL LEAKS FROM THE BOTTOM.

WITHIN A WEEK BOTH FRONT AND REAR PASSENGER WHEEL SPEED SENSORS FAILED. RESULTING IN A PROMPT ON DASH AT START UP AND CONSISTENTLY DISPLAYED FOR AEB SYSTEM SERVICE AFTER VEHICLES AUTOMATIC SYSTEM SCAN AN SEE DIFFERENCE IN MILEAGE IN ATTACHED PICTURES. KIA TECHNICIAN SAID IT IS A COMMON ISSUE AND SEES ATLEAST 4-5 VEHICLES PER WEEK WITH THIS PART FAILURE.

MY 2017 KIA OPTIMA CAUGHT ON FIRE ON OCTOBER 15, 2020. I WAS DRIVING TO THE STORE AND HEARD A TICKING SOUND AND SOME NOISES. THE CHECK ENGINE LIGHT ALSO CAME ON. I PULLED OVER IN THE LEFT TURNING LANE ON THE HIGHWAY TO EXIT THE VEHICLE. I HEARD A POPPING SOUND AND SAW FLAMES. I EXITED THE VEHICLE AND IMMEDIATELY CALLED 911. MY CAR BURST INTO FLAMES.

I BELIEVE THERE IS A PROBLEM WITH THE TRANSMISSION IN THIS CAR. IT IS AN LX WITH THE 2.4L ENGINE GDI. IT'S THE STANDARD ENGINE. THE TRANSMISSION SEEMED "OFF" AFTER A FIRMWARE UPDATE. PRIOR TO THIS, THE CAR REALLY PERFORMED AND ROLLED NICELY. BY THAT I MEAN, THERE WAS NO DETECTABLE DRAY WHEN TAKING MY FOOT OFF THE GAS. IN DRIVING THE CAR NOW, THE CAR JUST SEEMS TO LUG, AS IT TAKES MORE ACCELERATION TO GET THE CAR MOVING. THE TRANSMISSION "HANGS UP" AT AROUND 40MPH, WITH NO LOAD ON THE ENGINE. THE TACH AT 40MPH OR THEREABOUTS, READS AROUND 1900-2200RPMS. THIS IS FAR TOO HIGH IN MY OPINION, BEFORE I GO A LITTLE FASTER, AND THE TRANS FINALLY SHIFTS TO THE NEXT GEAR, LOWERING THE RPMS TO WHERE THEY SHOULD BE AT 40 MPH. GAS MILEAGE IS DOWN APPROX. 20% TO WHAT I ENJOYED BEFORE THIS STARTED. I DID HAVE THE CAR BACK TO THE DEALER, FRED BEANS IN LANGHORNE PA, FOR ROUTINE MAINTENANCE AND MENTIONED IT TO THE SERVICE WRITER. OF COURSE (AND I MEAN THIS WITH ALL DUE RESPECT), THEY COULDN'T DUPLICATE THE EXPERIENCE. WHAT THE DID DO WAS WIPE THE TRANSMISSION MEMORY CLEAN AND WE STARTED FRESH. THE IDEA BEING THE TRANSMISSION WOULD RELEARN MY DRIVING HABITS. I DON'T PROFESS TO KNOW EVERYTHING ABOUT A TRANS LEARNING HABITS, BUT I DO KNOW THAT THE TRANS SHOULD NOT HANG UP BETWEEN GEARS FOR ANY REASON. DUE TO RETURN TO THE DEALERSHIP FOR REGULAR SERVICE. WILL MENTION IT AGAIN. OUT OF REGULAR WARRANTY BUT I DID PURCHASE AN EXTENDED WARRANTY.

THE CAR STALLS AND HESITATES AT TIMES WHEN THE ACCELERATOR IS PRESSED

I JUST PURCHASED MY 2017 KIA OPTIMA TWO MONTHS AGO. I WAS DRIVING TO WORK TODAY IN THE CENTER LANE ON THE HIGHWAY AT ABOUT 65 MILES PER HOUR. OUT OF NOWHERE WITHOUT WARNING MY CAR SHUTTERS AND THE CHECK ENGINE LIGHT COMES ON. MY VEHICLE IMMEDIATELY LOST ACCELERATION AND GOT DOWN TO ABOUT 45 MPH AND WAS FALLING FAST. CARS WERE FLYING AROUND ME AND I WAS AFRAID FOR MY LIFE, I HAD TO FIGHT MY WAY OFF OF THE HIGHWAY TO GET TO SAFETY. I WAS LOOSING SPEED THE WHOLE TIME AND ALMOST GOT INTO AN ACCIDENT. I GOT INTO A PARKING LOT AND LET THE CAR REST. I CHECKED ALL MY FLUID AND OIL AND EVERYTHING WAS FULL/ FINE. I DECIDED IT WAS A FLUKE AND TO TAKE A BACK ROAD TO WORK. BIG MISTAKE. THE CAR WOULDN'T GO OVER 20 MPH AND I PRESSED THE ACCELERATOR DOWN WITH NO LUCK. THEN ALL OF A SUDDEN THE ACCELERATOR WORKED AND MY CAR SPED UP TO 25 MPH FROM 15. THIS WAS ALSO EXTREMELY DANGEROUS. I PULLED BACK OVER AND CALLED RICK CASE KIA. MY BOYFRIEND USED HIS CODE READER AND FOUND OUT IT WAS THE KNOCK SENSOR. THATS WHEN I FOUND OUT ABOUT THE LAWSUIT. I SCHEDULED AN APPOINTMENT AND GOT A TOW TRUCK TO TAKE THE CAR TO THE DEALERSHIP. WHEN I ARRIVED I MENTIONED WHAT HAPPENED AND SAID THAT I JUST FOUND OUT ABOUT THE LAWSUIT FROM THIS ISSUE. THE ONE SERVICE MANAGER FREAKED OUT THAT I MENTIONED THE LAWSUIT IN FRONT OF OTHER CUSTOMERS AND JUMPED TO EXPLAINING HOW MY CAR WAS ALREADY HANDLED AND THIS ONE ISSUE IS COVERED FOR LIFE. THIS MEANS THEY ADMITTED TO KNOWING ABOUT THIS LIFE THREATINING RECALL WHEN SELLING ME THE CAR. IF THEY DISCLOSED THIS CRUCIAL INFORMATION THAT I HAD THE RIGHT TO KNOW, I NEVER WOULD HAVE BOUGHT IT. THEY WILL ATTEMPT TO FIX IT AGAIN BUT I AM TERRIFIED TO DRIVE IT.

ABS LIGHT AND TRAC LIGHT ON. RIGHT REAR HUB BEARING NEEDS REPLACING. VEHICLE ONLY HAS 78,000 MILES.

A LOUD KNOCKING NOISE IN THE CAR 61K MILES..BASICALLY THE DEALSHIP IS SAYING THE CAR NEEDS A NEW ENGINE

2.4 L HAVE METAL SHAVINGS IN THE OIL

A LOUD SOUND COMING FROM ENGINE. CAR WELL MAINTAINED.

BOUGHT MY KIA 1 AGO & ALWAYS HAD A PROBLEM W/HEADLIGHTS ALWAYS TURNING ON & OFF WHEN IN AUTO MODE. TRUNK LATCH HAD TO BE REPLACED DUE LATCH NOT LOCKING WHEN TRYING TO CLOSE TRUNK. DEALERSHIP SAID THEY GET 20-30 LATCH ISSUES W/MY MAKE & MODEL OF KIA EVERY WEEK. AFTER VEHICLE STARTS CAR JUST DIES & ENGINE LIGHT COMES ON. AT TIMES CAR WILL STAY ON BUT STUTTERS LIKE ITS GOING TO DIE.
