SERVICE BRAKES, STEERING, POWER TRAIN
Vehicle: 2013 Kia Optima SXL VIN: [XXX] While driving on a highway at approximately 55–58 mph, the rear driver-side electronic parking brake (EPB) motor housing failed with a loud bang. Immediately after, there was heavy smoke and a strong burning smell. The vehicle became very difficult to drive, and the wheel began screeching and dragging as if the brake had locked. The failure appears to have caused the rear brake caliper to seize while the vehicle was in motion. This created a dangerous driving situation at highway speed and could have caused a crash. The brake system component that failed appears to be the electronic parking brake actuator/motor assembly attached to the rear caliper. This was a sudden mechanical failure, not normal brake wear, and it occurred while driving at speed.

FUEL/PROPULSION SYSTEM, UNKNOWN OR OTHER, ELECTRICAL SYSTEM
I am submitting this complaint regarding ongoing and persistent mechanical issues with my vehicle since the time of purchase. The vehicle has repeatedly shut off unexpectedly, creating a serious safety concern. Initially, I suspected the issue might be related to the battery, and I have replaced the battery twice within the past 4 years. However, the problem has continued. In January, the vehicle began shaking and shutting down again. I took it to a mechanic, who diagnosed the issue as faulty spark plugs and an ignition coil. The diagnostic codes provided were P0303 and P0456, and the recommended repairs were completed. Approximately one month later, the vehicle began shutting off again. I then took it to the dealership, where I was advised that the valve cover gasket needed to be replaced, along with the belts, and that a fuel system cleaning was required. I subsequently had these repairs completed by my mechanic. Less than a week after completing those repairs, the vehicle once again began shutting down. A diagnostic scan then produced code P123300. In addition to these repeated shutdowns, the vehicle consumes an excessive amount of oil, has poor acceleration, and continues to stall unexpectedly both while driving on the road and while idling, such as in a drive thru. These recurring issues have made the vehicle unreliable and unsafe. I am concerned about the risk of the vehicle shutting off while in motion, which could lead to a dangerous situation. I am requesting that this matter be reviewed for potential defects or safety-related concerns.

ENGINE, ELECTRICAL SYSTEM, STEERING
I purchased a vehicle from Banter Auto here in Wichita, Kansas. I reviewed the Carfax beforehand and nothing stood out that scared me so I signed off and purchased the vehicle. I have had nothing but problems since buying which was 7 months ago and have spent $9000 on repairs. I’ve been told by several mechanics the last 5 times I’ve been in and out of mechanic shops it’s evident my car sat in deep water for a long period of time. I finally took it to an electrical auto specialist here in town and while he said it is evident my vehicle sat deep water for a period of time and while the corrosion hasn’t quite started to cause an electrical problem that it very well could down the road. I’ve given the man who owns the dealership and opportunity to make this right however he stopped responding. I believe that is illegal and I’ve been told it should’ve been a “flood title”. I will know for sure after seeing a I will know for sure after seeing an attorney this week. That was not disclosed to me or I would definitely would have not purchased the car. When I first got the car, the locks and windows were going insane flickering all over the place and Kia dealership told me it was quite crazy and nothing they had seen before, however, they were able to fix it. I strongly believe that when my car was flooded it caused something to happen that I’m only going to have to keep paying for overtime. I’m already in debt from the $9000 I’ve had to getting personal loans. This is causing me enormous emotional distress. Please help.

ENGINE, STRUCTURE:BODY, UNKNOWN OR OTHER
My teenage daughter regularly drives this vehicle. The vehicle began experiencing significant oil consumption, oil leaks, and intermittent loss of power. During an early inspection at an independent repair facility, a check engine code P1326 was identified. Due to the symptoms and diagnostic code, the repair facility advised that the vehicle could be heading toward engine failure and recommended that the vehicle be taken to an authorized dealership because potential engine issues may fall under manufacturer warranty coverage. The vehicle was then towed to an authorized dealership. During the first visit, the dealership retained the vehicle for an extended period of time, approximately two months. During that visit, several recommended services were completed, including replacement of spark plugs, ignition wires, and replacement of the valve cover gasket along with other recommended maintenance. During that visit, it was also stated that the vehicle has a known issue with excessive oil consumption. Because of this, the oil level is checked weekly and oil is added as needed. I also informed the dealership that the independent repair facility had identified code P1326, but I was told that the dealership diagnostic codes were different. After these repairs, the vehicle experienced another incident where it lost power and began idling roughly while being driven on a busy highway. The vehicle was taken back to the dealership. During that visit, it was stated that the fuel injector harness and oil pressure sensor needed to be replaced. The dealership also indicated that the spark plugs needed to be replaced again, even though they had been replaced at the same dealership less than a year earlier. At that time, I asked if the vehicle would be safe to drive for approximately one week because I needed to travel out of town and my daughter would need the vehicle. The dealership advised that it was safe to drive during that time. The vehicle was then brought back to the deal

HECU failure on my 2013 Kia. My specific VIN # is not included in this repair but the year make and model are under recall sc197. My brakes are going all the way floor. There is a leek internally inside the hydraylic electonic control unit which is a fire hazard as well as a hydraulic failure. This is a massive safety and liability concern.

About a month ago my paint on my 2018 Kia Optima snow white pearl car started bubbling, then it turned into peeling and has since then been coming off more and more. It is occurring right under the back seat of the drivers side window. Reading into this issue more, it is happening to many who own a Kia Optima owners, especially those who own the snow white pearl color. Kia is not helping customers who are out of warranty but since this is a manufacturer defect they should be, even if they are out of warranty.

Issue: My 2014 Kia Optima has repeatedly experienced overheating, flashing check‑engine light, and loss of coolant. The dealership has misdiagnosed the issue multiple times and returned the vehicle to me in unsafe condition. Safety Concern: The vehicle overheats while driving, the check‑engine light flashes, and the engine loses power. This creates a serious risk of engine failure while on the road. I am concerned about potential engine damage, stalling, or fire risk due to overheating.

ENGINE
The engine on my 2010 Kia Optima suddenly seized without warning around 150,000 miles. The vehicle had no knocking sounds or warning signs prior to failure. A mechanic diagnosed the vehicle with a seized engine. This created a sudden loss of vehicle operation. I am concerned this may be related to the known engine failure issues reported in Kia vehicles.

ENGINE
2016 Kia Optima engine locked up, vehicle stalled on interstate,heard a rod bearing sound, left me in limp mode trying to get out the way of 18 wheelers traveling behind me. Towed into Kia dealership which confirmed the engine locked up which has a recall #PI1802B KSDS, but denied to cover it because I didn't have this recall done. I also called Kia Customer Service, they denied me too and just gave me a case #[XXX]. I explained to them that I never received notice of this recall. So how could I prepare for something like this to happen while traveling from Texas to Louisiana to visit my grand kids. The dealership gave me a Quote of $9735 for parts and labor, which I don't have, I am still making payments on this vehicle. Now I am stuck in Louisiana with my vehicle, also it's going to cost me even more to have it towed back to Texas. Please help me understand why the dealership won't stand behind a safety recall or what one person I spoke with called a campaign recall, which ever! That I never received notice about this recall. I hope the "President" or the "President of the Company" will step up and help, after all we as Citizens don't have a problem spending our hard working money on purchasing these vehicles from the dealerships, to have things like this to happen out of our control. Thanks for at least Listening. GOD BLESS...INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
