Once foot of the gas it stalled/brake by it self. Engine oil consumption
I have a 2019 Kia Optima S with the 2.4L engine and 117,000 miles. The vehicle has diagnostic codes P1326 and POOOB. The check-engine light is continuously flashing, the engine is knocking, and the vehicle has lost acceleration and will not go over approximately 65 mph. I believe this may be related to the KSDS connecting-rod bearing issue under Kia campaign PI1805.
My energy in my car started messing up with only 150,000 miles it had a long knocking sound and it would not got over 20 miles while driving
About six months ago, I lost the heated steering wheel functionality in my steering wheel, then from there, I slowly lost functionality like cruise control, and the most recent now my airbag and horn do not work. If you press on the horn, it is silent, and the airbag light has been illuminated consistently for the last couple of months. I had this issue diagnosed and it came up with the codes of B1346. And B1481. After some research, these issues are the result of a bad clock, spring and cause the airbag and horn...

not to work. Additionally, this issue is known to this model the 2011 Kia Optima, and has been recalled in most production cases of this vehicle, but my vehicle is not included. I received a quote for $876 from a dealership to get this corrected, but it should be included in the recall.
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 was driving on the freeway and my check engine light started to flicker and I felt my car shake and going to limp mode. I made an appointment with the Kia dealership and they told me the engine is failing. They submitted a request for a Goodwill case to Kia corporation and it was denied since there's no open recalls and is not covered by the extended warranty. the dealership recommended me to take my car and keep driving it even though it's unsafe the vehicle will not go above 50 mph and it starts to shake when driving I have tried to call Kia corporate and explain this situation but they have yet to follow up with me in my case
They were speeding with their phone in a phone stand watching a show while on the freeway
When the brake pedal is pressed on the brakes will grab. It snatches the car kinda hard. Also when you give the car gas it will hesitate and will not accelerate. Another with the gas is that you can be driving at a higher speed such as 45 to 55 or so and you press down the gas pedal like your going into passing gear and it will not accelerate it's like it's trying to stop. Feels like the car is gonna fall on down onto itself and it loses power.
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.
I have kept up on regular oil changes and maintenance on my Kia which I bought new 5 years ago. My issues started when my car's orange check engine light came on, I experienced loss of power such as difficulty accelerating even at low speeds, especially up hill. As soon as I was able I checked my oil which and there was nothing on the dipstick. I put in 3 quarts of oil. I brought it into my usual dealership for service and let them know about the oil issue and issues with power when driving. They failed to address...

the root cause of the issue, they performed an oil change, engine light turned off, and they started an oil consumption test. But when I drove off the lot the issue with the power continued, and the check engine light came on again. I took my Kia to another dealership to address the car's power issue and the first oil consumption test was not completed because it was unsafe to drive. When I brought my car in, the check engine light was not on, even though there were significant power issues. The dealership was able to confirm my concern, including loss of power and evidence of oil overconsumption. They replaced my turbocharger under warranty. I then underwent a 2nd oil consumption test that indicated overconsumption at a level of 1.5 quarts per 1000 miles. Then they performed a combustion chamber cleaning per Kia guidelines and a 3rd oil consumption test. They 3rd oil consumption results indicated overconsumption at a level of 0.75 quarts per 1000 miles. Although the dealership acknowledged this is still overconsumption, it was not to a level that required Kia to replace my motor. Meanwhile, after all these tests my car is close to out of warranty, at 98.6k miles. I called Kia customer care and their "resolution" to my case was the deny me a new engine and they would not provide me anything in writing. My car's overconsumption of oil and other signs of engine failure match the complaints found in class action settlements related to other Kia models.
While in park and driving the instrument panel will show, "Check Brake" and "Hybrid System Warning! Safely Stop and Do not Drive". This is accompanied by the engine not responding to the gas pedal. The brake pedal will also loose pressure and once pushed the brakes will lock up making a grinding noise. The problem has not been able to be duplicated by the dealer. However there are multiple forms and online communities dedicated to try to resolve this issue since it's so prevalent. This issue causes a major saftey...
