2014 KIA OPTIMA Engine Problems

Motor blew going down the road.

Check engine light was flashing and the car wouldn’t accelerate up to speed, wouldn’t turn over when tried to start.

The engine failed after a prior engine replacement performed by the manufacturer. The failure caused the vehicle to become non-operational and created a risk of sudden loss of power and engine stalling while driving. The vehicle required towing and could not be safely driven. This is a repeat engine failure involving the same vehicle.

My oil pressure sensor failed and is leaking oil into the electrical wire harness and all over the engine including intake and exhaust pipes which is a fire risk. It is the exact same issue as another recall affecting 2011 to 2014 kia models/years: 2019 safety recall (RCONL-19V101-0000) that involves replacing the oil pressure switch in certain 2011-2014 models if a leak is found. Additionally, a 2022 Technical Service Bulletin (MC-10210268-0001) extended the warranty for the oil pressure switch replacement to 15 years/150,000 miles for eligible vehicles. The recall addressed potential oil leaks, and the warranty extension covers the switch itself. 2019 safety recall (RCONL-19V101-0000) What it covered: The recall was for certain 2011-2014 Kia models and involved inspecting and potentially replacing the Oil Pressure Switch (OPS) and the oil pan if an oil leak was detected. Unfortunately at this time the dealership is claiming that this recall does not...

My 2014 Kia Optima is burning oil heavily and emitting fumes into the cabin. The dealership confirmed an engine issue but said they are waiting on paperwork to replace the engine. I’ve been told to continue driving it even though the burning smell enters the car and causes headaches. I believe this is a safety hazard.

While driving my 2014 Kia optima on the freeway the vehicle lost power completely and the car stopped almost causing me to be rear ended. I have reached out to Kia in Dublin since the vehicle should be covered under SC147 the vehicle has been at KIA since May and Kia is refusing to do repairs.

While driving home one day, the engine shut off while in traffic. The engine light had started to blink right before. The battery, starter, and oil levels were fine. A mechanic later confirmed the engine was locked. I see there are articles stating there were engine recalls for 2011-2014 Kia optima’s, but my 2014 Kia Optima EX was denied. Please help. I love my Kia. Thanks.

On 3 July 2025, while driving the car suddenly lost power and started smoking under the hood. I pulled over, exited the vehicle, and an engine fire started a minute later. The fire department put out the fire. The safety of myself and my child were at risk. We were driving at 40 miles per hour when the car lost power and caught fire. There were no warning lights. The car was towed to an independent repair shop to be evaluated, but results have not yet been gathered. There are known issues and recalls associated with 2014 Kia optima and with its engine losing power and catching fire, but my VIN was not included in the recalls when it should have been.

There was no accident or anything the problem just happened out of nowhere there was only sound then the car shut off and the engine stopped working

I noticed my oil was not staying in the engine. Oil has been changed but seems not to retain. The car stalled out on February 2nd and would not restart. I believe it is seized. Noticed a very new and recent shake during braking days before it stalled. The fuel seems to show like 42 miles to go until empty but run out , i guess fuel pump or fuel float. Also a fuel smell. Also the digital service option does not work never a check engine light or anything .I've read many things by others who own same vehicle and had same issues. I purchased this car in August/September. I feel the dealer may have known of these issues and still sold the car.Please help me figure out how to address these issues to get it fixed.

Hit dig mark in road caused by a plow about a half inch to a 1 inch deep by 5 to 7 inches wide while driving 15 mph down the road into work on November 19,2024 around 1:03/1:10 pm next thing I know I am upside down in my car in a ditch about four to five feet wide by 3-4 feet deep

Upon an engine light appearing I immediately turned the car around, and parked it at my fiancé's house. I had called kia and it was a little bit until I could take my car In. I had driven it over there which did ride a little rough. Informing kia of my issue they inspected it. I was told the second cylinder had melted which was caused by a spark plug. I do not understand how this happened, Kia said I am responsible for this and that they will not cover any repairs. As a result my car is junk and I am now left without a vehicle. I believed that it was caused due to the Theta II Class Action law suit as the only possibility for this happening is due to the fact that the car consumes large amounts of oil and constantly needs replenished. Which I believe is...

Complaint Summary: I am the current owner of a 2014 Kia Optima, which is affected by recall 23V652 related to the Hydraulic Electronic Control Unit (HECU). The vehicle was imported to the UAE, and the recall was not addressed by the previous owner. As a result, I am now facing significant safety issues.

Motor seized up

My engine locked up while driving down the interstate. I was almost hit twice because I was in the middle lane trying to get over and it was slowly giving out.

My son and his pregnant fiancé were traveling on [XXX] West bound Thursday [XXX]. They just got out of a construction zone near Rolla MO. At mile marker [XXX] the engine shut down with no warning at 60 mph and all the lights on the dash came on. He had a hard time controlling the car due to the steering being very tight and the brakes were manual. They got a tow to a safe place. I drove 5 hours to meet them and used a scanner to see what codes the car had. Zero codes showed up on my scanner. The engine immobilizer was engaged. We could not get the car started so I rented a U-Haul and car dolly and brought the car back to Indiana to the Avon IN Andy Mohr Kia dealer where we bought it. It was scheduled to be seen Tues [XXX] at [XXX]....

Car started to leak out the fuel pumps pressure system started to leak gas

The car is available for inspection upon request, but I plan to finally get rid of it soon. I worry greatly about the next driver that ends up with this car. While driving, a message pops up on the dashboard that says "Check Hybrid system. Stop vehicle and turn off engine". I've learned that I have about 15 to 30 seconds to find a safe place to pull over or the car will shut off on it's own. This has happened on the freeway at 70mph and it's happened at 20mph while driving through my neighborhood. I bought the car used in 2017 and this would happen once every six months or so. In the past couple of years it's gotten more frequent. This car is going to get me or someone else seriously injured or killed. I'm always on edge that this will happen while I'm on the freeway...

Exact same issue happened to my 2014 Kia Optima Hybrid (NHTSA ID Number: 11556409). I was traveling on the freeway approximately 65mph and out of nowhere the engine turned off, brakes did not work and steering quality went to a manual operation. I almost got into a serious accident as I could not control my vehicle. The hybrid system warning light, to stop using the vehicle became illuminated for approximately 30 seconds. The vehicle was towed to the local dealer ( Koons Kia, 14208 Richmond Hwy, Woodbridge, VA 22191, United States). We are still awaiting diagnostics. A few years ago the standard hybrid light came on (not the same warning light) in which we took it to the same dealer to fix. It was still under warranty at the time, however took them weeks to fix the issue as I had to take it back multiple times. They eventually replaced...

I was with my family on PA I-476. While traveling home in our 2014 Kia Optima the vehicle’s dash lights such as oil lamp, battery, etc popped on. As soon as I noticed the lights the vehicle had completely lost all drivability. Lights operable and possibly radio and accessories but I had to react so quickly as it was so unexpected. The vehicle completely lost its function and I was unable to operate it but in the capacity of steering and hardly able to break. Lost all power components. We are so thankful I was able to make a split second decision to dodge traffic while vehicle was decelerating, 18 wheelers going by 70+ mph (speed limit) and pulled off to one of the few shoulders. This scenario was so dangerous that if I didn’t believe in a higher being before, I do now! Most the lanes are sandwiched by...

engine was replaced per CASE # 14397135, and PI1803Y/Z, SINCE engine repair Turbocharger Boost Control Position Sensor “A” Circuit High CODES (P2562 & P2565) continuously come and go. Check engine light comes on and off for the same codes. Knocking noise continues, loss of acceleration as if voltage or gas was lost, steering wheel speed control buttons (+/-) no longer properly function since engine replacement. It now has a class 2 leak. Safety risk:when driving it loses speed or fails to accelerate may cause crash. KIA dealership has tried to access the code but Codes are spontaneous, same for loss of acceleration.

Summer 2017 The engine failed while driving with my family. The engine seized and a fire was engulfed. I was in the interstate and we feared for our life. Out of town visiting family we were stranded in another state for a month waiting for repairs. Kia took the vehicle and replaced the engine with another faulty engine that has seized several times while commuting. I have been living in fear and anxiety since this incident. I never know if I start my engine if I will loose my life. Summer 2023 3 teenagers watched a viral tic tok challenge and learned how faulty the cylinder that Kia installed was. The teens then trespassed into my home, broke the windows and stole my vehicle. I have lived in fear since this has happened. I have lost jobs, income, and peace due to The purchase of this vehicle. Kia has never...
