Factory Paint Defect Inherent, known to KIA models 2015 Optima Snow White Pearl Paint SWP. (including 2013 thru 2017 all share the same identical paint code). Citrus KIA in California inspected my vehicle and confirmed the paint damages are a known inherent factory paint defect. This is a nation wide issue, thousands of owners continue reporting this inherent paint defect on their Optima SWP. Basically this is an issue with all car manuacture's with white paint. Toyota and Hyundai accepted responsibility for this same factory paint defect and is repairing their customers vehicles. Class Actions Lawsuits have been filed against KIA and Hyandai for this known factory paint defect with severe safety concerns. This paint defect expanded into the layered glass of the windshield causing the adhesive to bubble. Insufficient adhesive could detach it during a crash or break while driving. The large chunks of paint continuing to fall off even while driving could impair visability to myself and other drivers. Citrus KIA inspected my vehicle and confirmed the damages to my vehicle are caused by this known factory paint defect. Wrote me an estimate reopened my case originally report 6/2024. Corporate KIA closed my case with the explanation 3/36k paint warrant expired. This is not a paint warranty issue. This is damages caused to my vehicle and thousands of others with this same inherent factory paint defect known to KIA. It is the manufactures responsibility to make this right. This inherent defect continues to rapidly spread through out our vehicles, causing further damages. These untreated areas now have rust subject to corrision which will lead to integrity of the body structure. Please recall this inherent factory paint defect. It's over whelming how many owners continue reporting this to their dealers, posting pictures of their ruined vehicles. We need help. Please recall SWP of Optima 2013 thru 17 with no limitations how old or amount of miles. Thank you

ENGINE
I own a 2015 Kia Optima (VIN:[XXX]) with a 2.4L GDI engine. The engine has failed — a local repair shop diagnosed it as a “jumped timing” issue, which matches the well-documented Theta II engine defect. I never received recall notice or notice of the required KSDS update. Kia has denied me coverage, stating the update was not done before failure. I now have a vehicle that is undriveable and potentially unsafe. Kia confirmed there is no extended warranty or coverage for rod bearing failure — despite widespread issues — and they ignored my open fire-risk recall (NHTSA 21V331000) in their denial. I am requesting that NHTSA review why my VIN is excluded despite the same failure symptoms, and ask that Kia be required to expand recall eligibility or offer a goodwill resolution.

This is about paint damage on my Optima is a known factory paint defect.This factory paint defect, specifically paint delamination causes bubbling, peeling then flaking off in large chunks while driving, has been reported on 2015 KIA Optima with white pearl paint. The damages ares are exposed to the metal, subject to rust and corrosion. On 5/30/35 KIA in Ontario, Ca. Body Shop Manager Yvonne Ramirez inspected my vehicle and immediately confirmed the paint damages to the exterior of my vehicle is a known factory paint defect on 2015 Optima with white paint. Yvonne instructed me to contact Corporate KIA, report the case, receive a claim # then contact her to schedule an appointment for the repair. On June 3, 2025 KIA reopened case number [XXX] originally reported on June 11, 2024. No claim # issues, no repairs made. Safety Concern: The paint damage has affected both sides of the adhesive inside the glass securing the windshield. This is a nation wide problem. Owners have documented and continue to keep reporting this problem to KIA, NHTSA, AutoLine and BBB. Several class-action lawsuits have been filed against KIA in USA and Canada. This is also happening to Toyota, Honda & Subaru. It’s basically all the car manufacturers who are using this pearl white paint. The amount of Optima owners dealing with the massive rapidly spreading paint defect to their vehicle is over whelming. December 2023 my 2015 KIA Optima SXT Pearl White beautiful exterior paint began to bubble, peel, flake followed by large chunks of paint falling off even while driving. This started on the roof top right and left of the rear window. February 2024 - the same paint damages started on the right and left sails/pillars next to the front wind shield and is causing damage, bubbling and spreading through out the left and right side of the glass. It is a safety concern. March 2025 - the same paint damage started on the top right truck with huge chunks of paint falling off while driving.HELP INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INF

ENGINE
Car was purchased April 2025, I’ve had it less then 2 months and check engine light came on and then flashing. I had it scanned at Auto Zone and was told the code is VVT Solenoid. I had it replaced 6/12/25. I was told by the mechanic that it didn’t solve the issue and metal shavings were on the old one. The car is still constantly going in to limp mode and there’s a knocking noise now. The Auto zone scan listed the mileage as 150,000 yet the car dealership listed and sold it as 101,000. I have a 2015 Kia Optima Ex. The title does not list it as a rebuilt and appeared to be fairly clean and maintained . The mechanic told me the engine needs replaced.

ENGINE
As I was driving going at a rate of 40 MPH my engine shut off. I was able to pull to the side of the road without an accident thankfully. Cranked the vehicle back up and then the same thing it happened again. No check engine light came on either time. Drove for another 200 miles no issues. Going apx. 75 MPH it went into limp mode and check engine light came on and the P1326 code appeared. There is a recall on this vehicle for this code. However the dealership states it’s a knock sensor needing to be replaced and I will have to cover that. The same knock sensor they had me update in 2018 under there advisory. The motor burns apx. 2 quarts of oil every 3000 miles. Requires oil to be added to maintain oil level in between oil changes. Irregular mechanical noise (rattle) during cold start ups. I am scared to drive this vehicle and do not feel I am being treated fairly due to the recalls on this engine.

I was driving on the freeway when I noticed smoke coming out of my hood. I immediately exited the freeway, pulled over, popped the hood open, and my engine was on fire. There were no warning lamps on my dash. I don’t know which components were involved and inspection of the components after was not possible, because everything under the hood burned by the time firefighters responded.

ENGINE
I purchased a 2015 Kia Optima 2.4L GDI (VIN: [XXX] ) with a blown engine, which is covered under Kia’s extended engine warranty. I contacted Jim Butler Kia in Chesterfield, MO, where the last service was performed, and requested the free engine replacement under warranty. They acknowledged that the car is covered, but refused to perform the repair because the vehicle is not yet registered. I explained that I have the title in my name and proof of ownership, but cannot register the car in Missouri because it does not run and must pass safety and emissions inspection to be registered. Despite showing them the title and explaining the situation, they continue to deny warranty service. I believe this is unfair and against Kia’s warranty policy, which requires proof of ownership—not necessarily registration. I’m requesting the dealership to honor the warranty and perform the repair, as the issue is known and covered by Kia’s engine recall campaign. I am not seeking financial compensation—just proper and fair warranty service for a defect Kia already acknowledges INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE, POWER TRAIN
Vehicle experienced sudden loss of power while driving when cylinder 3 completely failed (0 PSI compression). Metal particles found in oil and excessive oil consumption (1 pint/100 miles). KIA dealer diagnosed as piston rings but ignored metal in oil that suggests bearing failure covered under recall campaign. Refused proper diagnostic testing. Vehicle now unsafe to drive with failed cylinder that could cause complete engine seizure while driving. Kia had all recommended services and oil changes since acquired in 11/2016. These service records demonstrate the progression of my vehicle's engine issues, from early oil consumption problems documented by York Auto Care in July 2023 (3 quarts low) to complete cylinder 3 failure with zero compression confirmed by Kia's own diagnostic testing in May 2025. Despite this documented history and Kia's own test results showing catastrophic engine failure, they have denied warranty coverage under their engine campaign that specifically covers bearing-related failures on my 2015 Kia Optima 2.4L.

AIR BAGS, SERVICE BRAKES, STEERING
I was driving on the Northbound side of the Interstate when my brakes failed when I pressed them to avoid a collision on the highway. The steering wheel malfunctioned when I tried to avoid a head-on collision with another vehicle. I couldn't control or stop the car, causing me to swerve left to right, and I then completely lost control of the vehicle. I crashed into the middle of the highway, but because my brakes had failed, the car continued at full speed into the Southbound side of the highway, causing me to wreck into a semi. The Colorado State Patrol investigated the accident. Right before I wrecked into the semi-trailer, I noticed all of the lights on the dashboard were off. My Steering wheel had fallen off completely, but the airbag never deployed even though every other airbag had deployed.
