Ms. Nadine Thomas, who is running for District 44 in Georgia, has served on the Georgia House of Representatives and the Georgia State Senate is my boss and know what I have been through with my vehicle and has heard from KIA in Athens GA that there is nothing they can do. I have a 2017 KIA Optima that I have been having problems with since around 06/2022 or a little before. I have been getting oil changes and putting oil in the vehicle every week or every other week. It finally took a mechanic to tell me it is an issue with Kia's and a recall due to the replacement of the motor because the cars are losing oil. I do not have an oil leak but losing it every week and replacing it and it is expensive for an oil change and a gallon of oil constantly. I have reached out to KIA Manufacturer and case was denied, BBB and KIA denied it all the way, through where I went has far as to the attributor. Georgia Attorney General and they sent a letter to the Bulldog KIA in Athens and they said I have to go through the process of either hearing a thumping noise or motor light flashing constantly and or car shuts off before my motor can be replace. None of this has happened. I had to pay out of pocket for a tune up which was over $300 in Sept 2023 and again early this year 2023 and no reimbursement but it’s on my KIA receipts due to oil consumption (leaking of oil) it’s causing me to keep replacing the spark plugs. Renting vehicles when they would have to keep my vehicle to replace the spark plugs, and missing time from work. They will not compensate me for it, replace the motor, and or provide me another vehicle. I feel also because I am a woman that I am racially profiled, I have been very professional, calm, and provided more than enough time, effort, and providing all the information to KIA and I am not getting nowhere or through to anyone that will hear me or understand what I am going through. Previous NHTSA ID Number is 11518826, awaiting for response back from Ossoff Office.

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.

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.

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.

My 2017 Kia Optima is running out of oil between oil changes which I do on time. Before my next oil change it has no oil reading on the dip stick. I just had this occur again and I had to add two quarts. The oil light only blinked on for a second. When I checked it, no oil was reading on the dip stick. Taking it to auto store I was told by worker his mother has the same problem with her 2016 Kia and they replaced the motor in a recall. Mine is a GDl engine. Something needs to be done with these engines. I'm having the same problem a lot of other people are having.

To whom this may concern, I have had my car for several years now and the oil consumption is outrageous. I burn 5 quarts of oil every 2-3 weeks. Every time I had taken my car to get oil changes I am told that my specific engine has always been an oil guzzler. Well fast forward to last week. I was driving my car to work when the engine light came on and my car no longer wanted to accelerate. I pulled over and turned the car off. I changed out the battery considering maybe this was the issue. This did not fix the issue. I ended up towing my vehicle to the Kia Dealership in Hurst. I was told that I had 2 broken cylinders and my engine is not replaceable. My question to the service tech was how would my cylinders just break? I was given no answers but a number to call. This number ended up being Kia Consumers who don’t call me or answer the line. I have had the knock sensor replaced which should cover me for any extended warranty that is said to be in place but I am pulled in circles. I need help getting my car through the motions.

Have lost 4 qts of oil in the last month. Brought it to the mechanic and they couldn’t find any leaks. They said the only way I’m losing oil, is that the car is burning through it. They’ve seen the same issue with these cars. Only 65,000 miles on it.
