I was driving at 65MPH on the highway when the warning lights went flashing on my dashboard with "Check Hybrid system", "!HEV", and check engine light. I pulled over to the side of the highway and had a tow truck took it to the dealership to check out. Kia dealership did a diagnostic and mentioned the hybrid engine failed to convert from hybrid to gas and vice-versa. I am at 165,531 miles and Kia is charging me $13,000 to fix it. I am over the warranty of 150,000 miles. The "Check Hybrid system" message has been ongoing since 2021 and Kia mentioned it has to do something with the hybrid battery and Kia no longer makes a replacement battery for the Kia hybrid optima 2017. All Kia does it reset the system for the "Check Hybrid system" message to go away. After a few weeks, the message will appear again on the dashboard. I have upload an image of the dashboard with all of the warning lights. I need help as this is costing to much to fix.

I was getting on the freeway and my car suddenly just stopped accelerating. I even tried pushing the pedal to the floor and all power was gone. I was almost ran down by a 18 wheeler who must not have noticed my hazards had been switched on. A warning came on -??check hybrid system. Turn off engine-?? When the car lost its momentum as I was pulling over and eventually came to a stop I followed the warnings directions and shut the car off since I couldn-??t get any further anyways. I tried turning the car back on and then all lights and power instantly started flickering on and off and going crazy and then the warning came back on and then the whole car shut off by itself. I have been too scared to drive it since and I just got it back in October and I need a car to get to work and school and I don-??t know what to do but the amount of danger this issue put me in is unsettling and cannot be overlooked. Not sure what caused the malfunction because so many different things happened at once that it was hard to tell It is available for inspection upon request A service center confirmed that there is a problem and they believe it is related to the coolant pump and hybrid battery There was one other time that a warning came up and it just said -??check hybrid battery-?? but it went away only like a minute later and then a couple days after that I came outside to go to work and the car was dead but then I jumped it and it was fine up until the issue I first mentioned happened where I was put in danger A warning light that said !HEV and the check engine light both appeared

I was driving in morning traffic at 65MPH when the warning lights went flashing stating the HEV Electric engine was shutting down, I was crawling to 20 MPH. I had the car towed to a Kia dealer and was told the electric engine was fine, the gas engine oil was bone dry! NO LOW OIL light ever triggered! Not a single warning. Just out of the blue! This is wrong on so many levels! I get oil changes when they are due and use top synthetic oil. The dealer is reporting it to Kia and said at 87,500 miles I'm under the extended warranty, but Kia will tell them how to handle the issue. I cannot afford a new engine! This is the second Kia I had this problem! They said it passed the bearing test, so why is my engine bone dry? This is dangerous to be driving at high speed and have your car drop speed to 20MPH, then drop to 10MPH. I'm still waiting for Kia to get back to me, the dealer says it takes 48 business hours. I dropped it off Thursday 1/11/2024, Hopefully, tomorrow I will find out. I cannot afford a new car and I still have a balance on this car. I've read multiple complaints on this sight, all the same.

While driving my car started to decelerate in the middle of the freeway and I was in no position to pull over. The hybrid battery nearly completely drained before I was able to limp off the freeway. My car threw an error message to -??Check Hybrid system-?? and told me to pull over immediately and turn the car off. After pulling over, turning the car off, then turning it back on, the message went away but the check engine light remained. After 24 hours the check engine light disappeared until it would randomly do the same thing all over again. I ran an OBD code reader on it and it gave me P2600. After extensive research, I-??ve noticed a lot of Hyundais and Kia-??s around the same year as mine having the same issue with some peoples vehicle completely dying. Many threads take their vehicle into the dealership and they can-??t replicate the problem so they-??re just sent on their way for the dangerous problem to happen again at any given time. This is a dangerous situation because you don-??t get any warning or strange engine noise to warn you. The car just pops up this message and the engine immediately starts to malfunction.

This pre-owned vehicle lost power at an intersection with my wife and child in the vehicle. Both of them were fearful and in tears. Several indicator lights suggested problems with the engine, HEV system, and battery. Upon returning home, I notified Carmax and scheduled the vehicle for service at a local Kia dealership. Although the mechanic told me that he knew there is a problem with the vehicle, Kia failed to diagnose or fix the problem(s), and could not assure me that the vehicle was safe to drive. Maxcare would not cover a rental car because no diagnosis was made. Kia also informed me of a previously undisclosed, long history of problems going back to 35 miles on the odometer. I requested a copy of Kia's vehicle history report and Kia refused to provide it. I also reported this safety concern to Kia Consumer Affairs, who provided no immediate solution, said they would contact the local Kia dealership, and referred me to an "ongoing" class action settlement at [XXX], which indicated that the settlement had closed on 8/9/21. Because no other option was offered to me, I was forced to pick up the vehicle from Kia. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Driving down the interstate, the vehicle started to decelerate and the engine light started flashing. Got it to a mechanic and he started that it was a knock sensor failure P1326 code. Same as the recalls, but my vin number was not included in the recall report. Already had this vehicle in for excessive oil consumption. Paid for the dealer consumption test. They said it only burned a qt. and that was acceptable. In 1000 miles. Have done my own 1000 mile test and have been burning 1.5 or more qts. on three separate tests. Something has to be done about these engines. This is dangerous when going interstate speed and dropping to 20 mph in heavy traffic.

The engine on this vehicle caught fire while the vehicle was parked and not running. It had previsouly been drive for approximately 4 hours throughout the day but at the time of the incident there were no warning dashlights present. It is currently available for inspection, however depending on the length of this invesitagion it may no longer be available as i work with my insurance company determing next steps. My safety and the safety of other were put at risk by and open flame and smoke that occured during the fire. Ultimately the Fire Department were required to put out the fire. Approximately 8 months ago the engine was replace by the dealership Summit Place Kia East in Michigan due to an open recall for a knock sensor issue. I suspect this vehicle will be a total loss.

Very small hill u come to u lose power and it goes jerking. I thought several times I would get rear ended by the vehicle behind me I'm scared to drive this and when the car is running and you step out of the car the smell of gas is very strong and it is using a lot more gas than it mostly does. This happened to me September 20th2023.

Complete engine failure while driving 70mph down the freeway. No lights came on before engine started shaking, knocking, and failed. We were stranded at a gas station. We checked oil and there was none. (This was shocking because we changed oil regularly and car had just received complete oil change several weeks prior) We bought enough oil to drive it to nearest auto mechanic shop. He inspected the car and said complete engine failure and that we needed to contact KIA immediately. Spark plugs were burnt and melted more than he had ever seen. He said this is a recurring problem with their engines. (A few months prior to this incident, check engine light came on and car had a slight sputter during acceleration. We took the car to local repair shop. Car received complete tune up weeks prior to incident and check engine light was resolved.) Car was taken to Kia dealership in Little Rock, AR. Diagnosis: Major oil consumption caused engine to overheat and lose pressure/fail. Engine is non-repairable. New engine will cost $10,000. Kia will not back their product. After investigating further, I have found a Facebook group with tens of thousands of people with similar incidents in their Hyundai/Kia cars. This is a dangerous problem and KIA needs to be held accountable. The most recent class action settlement DOES NOT cover engine failure due to major oil consumption, only rod bearing failure. Where is the oil going" There were no leaks detected, no oil light to warn me. Where does the oil go? Burning up through exhaust" Surely that violates some sort of environmental standard that car manufactures should be abiding by. These cars are dangerous to consumers, and bad for the environment. I-??m stuck with a car that I still owe money on that is worthless. If I spend $10,000 to repair, they will put the same engine back in the car and I will repeat the cycle of engine failure and loss.

My car does not accelerate easily and struggles with basic speed. I took it to a mechanic and am being told that my turbocharger has failed and must be replaced because there is fuel in my oil and there may be damage to my engine as a result that would require me to replace the engine. This is the second time in less than 2 years that this has happened since I have owned this vehicle. The mechanic says the engine could seize up or catch fire at any point and that I will have to have the oil drained, flushed, and replaced, hopefully have the fuel leak found and repaired, then the turbo replaced. Only once all of that has been done will I know if the engine will still be operable. The first time this happened it was repaired at a Kia dealership in Denton TX under warranty. The vehicle is no longer under warranty and should not have this problem every year.

- San Antonio, TX, USA

Engine needed to be replaced as part of the recall for knock, however they said because the repair was done on a subsequent work order and the first one was for a failed AEB module that none of the repairs are covered. I'm out over $13,000 for what should have been warrantied
