I am reporting a recurring safety hazard involving my 2019 Kia Optima following a repair for diagnostic code P064A (Fuel Pump Control Module). Despite the dealership attempting to repair the fuel system, the vehicle remains in a 'limp mode' state. While driving, the vehicle began shaking violently and lost significant power, refusing to accelerate above 50 mph. This creates an immediate safety risk, as the vehicle cannot maintain highway speeds or safely merge, increasing the danger of a rear-end collision. The P064A code and subsequent 'limp mode' symptoms persist even after professional service. I am concerned that the existing Kia warranty extensions (such as WTY028 for the low-pressure fuel pump) or current repair procedures are insufficient to resolve this underlying mechanical/electronic failure, leaving the vehicle unpredictable and hazardous to operate in traffic.

I just recently purchased my 2019 Kia optima sx turbo. After purchase, I immediately began experiencing issues with the braking system and the forward collision warning light coming on. The cruise control stopped working as well. I googled and saw that there was a recall on the forward collision warning system but the local Kia dealership to me says there is not one. I almost had a head on collision in this car with my granddaughter coming from daycare as I completely lost brakes. I have put so much money into purchasing this car believing it to be a good car.

While I was drive these warning lights came on as you in the picture there are no signs of a crash. I have took my car in for service at Kia of Bradley for them to reset my system on 7/01/2025 and they have came back on and they would not go off. I feel like this is a recall on my Kia Optima 2019.

Oil is getting into cylinders causing spark plugs to misfire. Very high oil consumption so I have to put oil in it every other day in between oil changes. I’ve been to Kia Service department several times in the past 2 months.

UNKNOWN. Vehicle is burning through oil every 1,000 miles or so. Excessive oil consumption which i am aware there is a recall. However Kia states my VIN # is not included. While at the dealer service department for failed A/C system, we questioned the excessive oil consumption and engine replacement. We were told they found nothing wrong. Having to top off oil every 1,000 miles or so. It does not make it to the next oil change before the light comes on. No oil leaks. Mechanic said known problem with this engine. Most recently the starter went bad, alternator, and battery. Replaced with a second brand new battery and car won't start again. Dash is lighting up erratically, new battery dead. As if something is drawing all power and draining brand new batteries. This car has a little over 86,000 miles and one thing after another is failing. The car lost power and power steering in a curve leaving us in a dangerous situation after replacing the starter. Dash lighting up erratically with front end collision warning message on the display. We had it towed to our residence which our auto insurance reimbursed us for. Replaced alternator and battery yesterday, and the car lost all power again turning back onto our street, again with the Dash lighting up erratically.

Sometimes when I drive it will say my forward collision is blocked so it will disable but it normally shuts off. Tonight I'm driving on the freeway a steering wheel pops up then blind spot abs traction and a few more lights come on then it say check headlights those are dimming the radio is cutting off. The wipers aren't working but the car is still accelerating then all of a sudden the car goes from 55 to 0 the wheel locks and I have to coat to the side of the road.

Crash reported

It was snowing and an icy day Jan. 21 in Atlanta, Georgia. I was driving on Buford Spring Connector going southbound. I was on a bridge and it was completely white and icy. I saw there was a car stopped in front of me. I tried to put on my breaks and my car would not slow down. I was getting closer to the other vehicle still trying to break. I tried to use my electronic emergency brake and it did not engage. The car did not even try to break for me which it normally does if I moving faster than a stopped car in front of me. I rear ended the person in front of me. I just wanted to let someone know as the forward collision did not work in this case and the accident could have been avoided.

The engine is consuming oil very fast and needing oil way before the next oil change. The oil consumption test Kia did stated that it was 2 quarts low after the first 1000 miles. Car does not have extended warranty but this a manufacturing defect. Suggestion was new motor. Also it's recall for the forward collision safety feature but my car vin is not included even though it goes off when nothing is in front of me. They want me to pay for these issues the motor cost the same as the payoff of car. This is ridiculous, I purchased Kia due to having a older model that almost got 300,000 miles on it before transmission died. I got a great payment and a newer car but didn't expect to have this motor issue or safety problem with no help from manufacturer. I'm stuck keeping oil in car so it's burn out & cutting safety feature off so it stops breaking when nothing is in front me. Both of these issues or manufacturing defects and should be fixed by KIA.

My 2019 KIA optima with 116,021 odometer on mileage. Stop in the middle of High Volume Traffic , Because of Software Issues , I suspect . All Forward Collision Warning Detection , Also Rear Collision Warning Alerted on dashboard!!! Which Causes my Car to stop in the middle of Traffic Completely shut down. I was able to get my vehicle towed to KIA West Dealership Located in lithia Springs GA . I requested a diagnostic test and was informed by my service advisor and service manager that my vehicle has a burned out wire located in the left right rear sensors radar assembly, bumper area . Which will eventually have caused a fire or actually already did, I asked how did it happen? I was told it just simply burnt out. !!!! I was told the assembly box junction box needed to be replaced, which I agreed at that moment in order to diagnose the vehicle. Second the electrical problem was revealed, which is the big problem now currently for 1 , the vehicle is not safe for a midsize sedan on public roads and highways the if this make and model car causes random fires. secondly the parts very expensive and suspicious. I’m currently still doing my investigation. Unfortunately I had to agree for the sensors to be replaced and fixed because personal reasons I need my vehicle to get back-and-forth to work, etc.. I’ve been in contact consumer regional services, No one is able to find a recall with my Vin number the car never been in a accident ever. I have a picture of the hazardous burned out wire the technician showed me as well. As they claimed randomly caught fire.

I like kids however I purchased a Kia used in 2021, I started to notice that all consumption was going out fast before oil changes was due. I still have this ongoing problem but they say there's no recall on these GDI motors however other people I see informs or experiencing the same issues. I now have to try to get an appointment with Kia for an oil change before it's time for the oil change and to do a oil consumption test and then hopefully the main factors or kia will replace this motor even though there's no warranty on the car. I might also have a issue with the front collision feature because I have been noticing in the past few weeks that this feature comes on even when there's no car in front of me it will start to break however it says that my car is not a part of a software upgrade so I got to ask them about that as well. There is definitely a issue with the GDI motors and Kia really needs to recall them all and replace the motors it should not burn all the way that it does I've never had any car of any brand or manufacturer burn oil the way that this car is burning oil. I cannot financially afford to go out here and trade this car in and get another car with the type of payment that I have for this car since I had my bank finances car.

On March 2022 Forward Collision Warning System, Blind Spot Warning System, ABS braking System and other systems associated with a bad passenger rear wheel sensor not working. On March 17, 2022 rear passenger wheel sensor repaired under warranty by local Kia Dealer. In September 2023 same issue with the above warning systems occurs with only another 2,000 miles on car after previous repair. Local Kia dealer states both rear wheel sensors need to be replaced. Kia dealer states vehicle is no longer under warranty and will cost in excess of $800 to repair. After checking similar complaints online, I believe there is an inherit defect with this type of vehicle's wheel sensors and a recall is needed to enforce Kia to stand by their product and ensure the safety of the vehicle and their customers.

The second month after I purchased this vehicle the master warning light and forward collision light popped up and car vehicle started de-accelerating in the middle of the freeway and I had to pull over and then the car died. Repeatedly took my vehicle to the Kia dealership and no one still has been able to help me. They claim no one at their corp. Office in California what that means so it has been going off ever since and I don't want my vehicle to died again. PLEASE HELP!!!
