When driving on the highway my car suddenly started to stall with me on the highway. It went from 80 miles per hour to 20 miles per hour and then completely shut off in the lane of the highway. Thankfully I was able to pull over to safety. I attempted to start again, and the engine started with a weird noise coming from it. I had it towed to my local Mechanic who told me that my engine is part of a safety recall.

3 months prior to my car going into limp mode I had an incident where I was on the highway and had to come to a stop of major traffic and suddenly my car cut off out of nowhere. I got it to crank after putting it in park, but it was very scary being on the highway thank God it was traffic to where cars wasn't going so fast. Fast-forward to my recent incident to now my car's now in limp mode (MIL) same situation different times was getting on the highway and started to pick up speed to accelerate to 60mph my engine light started to blink Non-Stop and here I am again in a terrifying situation to where I have to get back off of the freeway and I also was on my way to work now having to call in and praying and hoping nothing happens to me while trying to get my car home now I've called I'm certain dealerships decided to go with a dealership to get my recalls done and the dealer basically told me he told his mechanics to hurry up and do my recalls that he could do and get my car out of their shop and also told me to get rid of my car basically refusing to do what he's supposed to do regardless but I truly believe I need a new engine and that's why the dealer rushed me out I just want to know how can I get my vehicle fixed with no problems and also without dealerships denying me. I would love to hear back from you all to know my next step in getting my vehicle recall done please and thank you
The last recall that was fixed is occuring again . Car loosing power warning signal popping up Sometimes smells like matches after parked.
Excessive shaking of engine, stalled out while driving on highway, knocking in the engine.
1st problem happened when I was at a complete stop, at a traffic light, in rush hour traffic. All the sudden steam started coming out from underneath my hood. I instantly looked at my temperature gauge and it did not show anything however I knew something was wrong when the light turned green I immediately pulled over, out of the street as far as I can get without being hit by other cars. I put on my hazard lights. Pop the hood. I had a gallon jug in my trunk. And I walked to a store to fill it up with water. Came back, poured the entire gallon into the radiator. Waited for at least 30 minutes. Started the car and made it home. After that incident, the problems with this 2015 Kia Optima has snowballed. It just amazes me that it has started happening 2000 miles after my extended warranty expired. I had to purchase and replace spark plugs, the coil packs, two other sensor things, which I do have the receipts for and now the car reeks a gasoline and it automatically kicks into overdrive and I lose my reading on my tachometer, this puts it into a disabled mode, I'm on the freeway in Russia traffic, trying to pull over without getting into an accident. Do I believe this is a safety concern? You're damn right I do am I mad yes. I am taking my k i a into the dealership. After doing my research on this make and model, is the dealership doesn't honor what the claims department and the media response to this problem. Will then I will leave the car with Kia because I cannot afford a new engine. I will have to call to finance company and let them know that I voluntary I'm letting them come repo this car, good luck selling it
The contact owns a 2015 Kia Optima. The contact stated that while driving approximately 70 MPH, the vehicle inadvertently decelerated to 60 MPH. The vehicle began to shudder and failed to accelerate above 20 MPH. The check engine warning light was illuminated and flashing. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The approximate failure mileage was 80,000.
My check engine light came on Sunday January 23rd. Upon Contacting my local Kia Dealership, I was told that my vehicle has recall # SC212 at which time was advised to bring my vehicle into the Kia dealership for diagnosis. On Friday, January 28th I dropped my vehicle off at my local Kia dealership and within 3 hours received a call from my Service Advisor who stated the following issues were found: 1. Oil leak; REPLACED: Valve cover gasket, high pressure fuel line, and high-pressureSe fuel pump bolts. 2. Recall SC212; REPLACED: Multi-Fuse and Fuse Box Cover per campaign instructions. 3. Serpentine Belt; REPLACED: Drive Belt 4. Brake Pads; REPLACED: Front Brake Pads and Machined Rotors. 5. Brake Pads; REPLACED: Rear Brake Pads, in addition to Replacing both rear rotors. 6. REPLACED: Cabin Air Filter 7. REPLACED: Engine air filter 8. Oil and Filter Change; Performed LOF, set tire pressures, and topped off all fluids. Less than 72 hours after the above repairs were complete, and a hefty $1,500.00 repair bill, my check engine light is BACK ON! My vehicle lacks acceleration when depressing the gas pedal and I am fearful my vehicle may have the defective Theta II Engine in it. I am a single parent with a 7 year old child and this has caused us to not feel safe driving our vehicle, not to mention I have had to miss multiple days of work and my daughter has missed several days of school now because we do not have a safe vehicle to commute to school and work in. Also, when searching my vehicles VIN number, it says the recall was not fulfilled? VERY CONCERING! I have the vehicle diagnostic data in my UVO Services account, in addition to itemized repair bill from Kia.

I was on the freeway and out of no where I couldn’t accelerate and immediately my car slowed down and I had to get over the car behind me had to slam on breaks and I was almost hit twice car then flashed to pull over and charge battery but it’s a brand new battery everything still turned on just couldn’t accelerate so it’s now towed to Kia dealership to get diagnostics done scariest driving moment ever
I WAS DRIVING HOME FROM WORK AND I NOTICED MY VEHICLE HAVING A HARD TIME PICKING UP SPEED AND SOON AFTER IT WAS A NOTICEABLE KNOCKING NOISE COMING FROM THE ENGINE. THE RPM AND DASHBOARD GAUGES WERE VERY SPORADIC. I PARKED THE CAR AND POPPED THE HOOD TO FIND THAT THERE WAS SOMEHOW ABSOLUTELY NO OIL, BUT NO CURRENT SIGN OF LEAKING FROM UNDERNEATH. THE CAR CONTINUES TO KNOCK WHEN I START IT UP AND AM AFRAID OF IT OVERHEATING AND IT IS CURRENTLY PARKED. IT SMELLS DEFINITELY LIKE BURNTNESS AND WHEN SHIFTING INTO D3 AND D IT SEEMS TO BE THE MOST APPARENT THAT THE ENGINE COULD BE HAVING TOUBLE. SPEEDS AND RPM GAUGE ARE MOST SPORADIC AT HIGH SPEEDS AND THE EXHAUST PIPE SEEMS TO HAVE RESIDUE OF SOME SORT THAT ISN'T NORMAL.
I WAS DRIVING DOWN THE STREET CAME TO A RED LIGHT AND WHEN I TRIED TO PRESS THE GAS MY WHEELS LOCKED AND THE CAR WOULDN'T GO. I HAD TO PUSH IT DOWN A HILL AND USE NEUTRAL TO GET AT LEAST GET THE CAR OFF THE MAIN STREET AND TOWED. THE NEXT DAY IT WAS TAKEN TO KIA AND NOW THEY ARE TELLING ME THEY CAN'T HELP BECAUSE I COULDN'T PROVIDE RECEIPTS OF ANY MAINTENANCE THAT WAS DONE ON THE CAR OVER TIME.
My car had started acting weird about 5 months after I got it, I believe Jan 2020. Only had it till Jan 2021 and they said my engine Barrings broke and it was going to cost me 10000. I didn’t have it. I was never informed about the recall. It messed up my whole credit and I still have not been able to get a car since. I moved and I was just now able to get the mail!
MY KIA STARTED OUT MAKING A STRANGE SQUEALING NOISE, THEN IT STARTED LOOSING POWER. WHEN I STOP AT A LIGHT OR STOP SIGN I PUSH THE GAS PEDDLE AND IT TAKES AWHILE TO GET UP TO EVEN 35 MPH. I WAS TOLD THE TURBO MANIFOLD WAS BAD SO I HAD ONE PUT ON. THE NEXT DAY IT STARTED MAKING A CHA CHA CHA NOISE. I TOOK IT BACK AND HAD TO GET ANOTHER TURBO, ONCE AGAIN SAME THING. KIA DEALERS SAID TURBO AGAIN. SO I'M OUT LABOR AND TURBO COST ONCE AGAIN. I HAVE TO WORK I NEED MY CAR, I NEED IT FIXED NOW. I LOVE THE CAR BUT I AM SO SICK OF STRESSING OVER EXPENSES, AND LOOSING MY JOB NOT ABLE TO GET THERE. I JUST WANT IT FIXED CORRECTLY, OR MONEY TO GET A DEPENDABLE VEHICLE. I'VE NEVER HAD PROBLEMS WITH MY GMC,CHEVY AND PONTIAC VEHICLES. I DO LOVE MY KIA BUT I WILL GO BACK TO THE MOST RELIABLE CAR. NO POWER IS DANGEROUS WHEN YOU NEED TO TAKE OFF BUT THE CAR BOGS DOWN. SO I YOU WILL I REALLY NEED TO FIND A MECHANIC THAT CAN TELL ME WHAT EXACTLY IS WRONG AND FIX IT. FIVE MECHANICS APPARENTLY DON'T KNOW EITHER. I DON'T NEED MY CAR TO CATCH ON FIRE. SO PLEASE TELL ME SOME GOOD NEWS THAT I WILL HAVE A DEPENDABLE CAR SOON.
THE CAR SPED IS FASTER THAN WHAT THE SPEEDOMETER DAY. THE CAR JERKS WHEN YOU ARE SITTING IDLE. THE OIL LIGHT KEEP COMING ON WHEN THE OIL STICK SHOW THAT'S ITS OIL IN THERE. CAR DON'T PICK UP SPEED FAST ENOUGH CHECK ENGINE LIGHT CAME ON. *TR

ON MARCH 7TH 2019, I WAS DRIVING DOWN THE HIGHWAY AT APPROXIMATELY 60 MILES AN HOUR I FELT A CLICK, & MY ENGINE LIGHT MY OIL LIGHT AND MY BATTERY LIGHT ILLUMINATED. MY CAR DID NOT SHUT OFF BUT GAS WAS NOT ABLE TO FLOW INTO THE ENGINE THEREFORE I WAS COASTING DOWN THE HIGHWAY. I WAS ABLE TO GET OFF ON TO THE EXIT RAMP I PULLED OVER TO THE SIDE, THEN I WAS ABLE TO SHUT MY CAR OFF. I THEN BEGAN TO RESTART THE CAR, & IT DID RESTART I PROCEEDED TO PUT IT IN DRIVE MOVE FORWARD, BUT THE THREE LIGHTS ILLUMINATED ONCE AGAIN. THIS WAS IN THE MIDDLE OF THE INTERSECTION. I SHUT THE CAR OFF AGAIN, THEN, PROCEEDED TO RESTART THE CAR, IT RESTARTED AND I WAS ABLE TO DRIVE THE REST OF THE WAY TO WORK, WHICH WAS A VERY SHORT DISTANCE. LATER THAT DAY I DOWNLOADED THE UVO APP IT DID A DIAGNOSTIC TEST AND FOUND NOTHING WRONG WITH THE VEHICLE., THIS TEST WAS WRONG, SOMETHING WENT WRONG & IS WRONG. ACCORDING TO PAST RECALLS, THE ENGINE HAS SEIZED AND SIMILAR REPORTS HAVE BEEN MADE. I FOUND THIS EXTREMELY SCARY BECAUSE OF THE FACT I WAS DRIVING DOWN THE HIGHWAY IN MEDIUM TRAFFIC, MY ENGINE STOPPED THE LIGHTS CAME ON AND I DID NOT KNOW WHAT WAS GOING TO HAPPEN. LUCKILY I WAS STILL ABLE TO MOVE THE STEERING WHEEL ENOUGH TO GET OFF ON THE EXIT RAMP AND TO PULL TO THE SIDE. I RECENTLY BOUGHT THIS VEHICLE AND I'VE ONLY HAD IT FOR 6 MONTHS. I HAVE HAD THE OIL CHANGED ONLY AT THE DEALERSHIP, AND ANY OTHER SERVICES HAVE DONE BY THE DEALER SHIP. I AM AFRAID TO DRIVE THE CAR BECAUSE OF WHAT HAPPENED, AND WHAT I HAVE READ FROM THE PAST EXPERIENCES OF KIA OPTIMA OWNERS THIS HAS HAPPENED TO.
I NOTICED THAT WHILE DRIVING MY CAR IT WOULD FIRST MAKE A NOISE AND THEN RIGHT AFTER IT WOULD STALL AND SPUTTER/ JERKING LIKE IT WANTS TO CUT OFF. I TOOK MY CAR TO A KIA DEALERSHIP FIRST IN ALEXANDRIA,VA WHERE THEY ONLY DID MY OIL CHANGE AND NOTHING ELSE BECAUSE THEY SAID THAT IT WOULD TAKE A WHILE FOR THEM TO LOOK AT MY CAR AND THEY DIDN'T HAVE A LOANER FOR ME, SO I THEN TOOK MY CAR TO THE FALLS CHURCH, VA LOCATION AND I EXPLAINED TO THEM WHAT WAS HAPPENING WITH MY CAR AND FOR ABOUT SIX MONTHS I WAS BRINGING MY CAR BACK AND FORTH THERE FOR OIL CHANGES BECAUSE THEY WANTED TO SEE IF IT WOULD STILL HAVE THE SAME ISSUES AND NO MATTER HOW MANY OIL CHANGES THEY DONE MY CAR WOULD STILL DO THE SAME THING. MY CAR WAS CLOSE TO THE MAXIMUM MILES FOR WHERE IT WOULD STILL BE COVERED UNDER MY WARRANTY TO GET FIXED AND I TOLD THEM THAT I WANTED TO GET THE ISSUE FIXED BEFORE MY WARRANT RUNS OUT. SO FINALLY THEY KEEP MY CAR SITTING IN THE SHOP FOR 1 MONTH WITHOUT ANYONE LOOKING AT IT AND COME TO FIND OUT THE GUY THAT WAS GOING TO BE WORKING ON MY CAR NO LONGER WORKS THERE, I WOULD CALL THEM TO CHECK ON THE STATUS OF MY CAR AND MOST TIMES I COULD NEVER REACH ANYONE AND THEY DIDN'T CALL ME TO KEEP ME UP TO DATE ON THE PROGRESS, SO AFTER ABOUT 1 1/2 MONTH THEY CALL ME AND TELL ME THAT THEY CAN NOT FIX MY CAR DUE TO LACK OF MAINTENANCE AND UP KEEP BY ME AND EVEN THOUGH IT'S COVERED UNDER WARRANTY, MY CAR ONLY HAD 57,000 MILES ON IT AND IT WILL COST ME $5000 + TO GET MY CAR FIXED. I'M STILL DRIVING MY CAR AND STILL HAVING THE SAME ISSUES, I'M VERY UPSET BECAUSE IT'S LIKE KIA DOESN'T EVEN CARE AND SEEMS LIKE THE PEOPLE AT THE DEALERSHIP WANTED ME TO KEEP COMING BACK AND FORTH SO THAT I CAN GET CLOSE TO THE MILES TO WHERE IT WOULDN'T BE UNDER WARRANTY SO THEY WOULDN'T HAVE TO FIX IT. MY CAR ISN'T FIXED AND I DON'T HAVE THE MONEY TO GET IT FIXED, I'M HOPING FOR A MIRACLE.
