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

For years there has been a problem with my vehicle after it rains. On the drivers side when turning the steering wheel there is a scraping noise. The dealership service always said they can’t hear anything or duplicate the problem. Now the issue has extended to the passenger side. After a heavy rain or going through the car wash water get in under the glovebox. My sunroof is fine and not clogged, the problem is something else. Water no matter the source should not be getting inside the car causing odor issues, interfering with the operation of turning / steering gears. This needs to be a recall to force Kia to acknowledge this well known problem from hundreds of online complaints regarding leaks.

The engine appears to be consuming an abnormal amount of oil. There are no visible leaks or external damage, and the vehicle has not yet stalled or failed, but oil levels drop rapidly between oil changes. The engine is available for inspection upon request Driving with low or empty oil levels risks sudden engine failure while in motion, which could lead to loss of power, stalling in traffic, or even a crash. The oil warning light came on and went off at regular intervals unexpectedly during driving this week, which prompted me to get it to my mechanic asap to avoid potential engine damage or failure. They performed an oil change (even though I had done it there for this same car only 2133 miles ago NOT YET. I have contacted the dealership and have been advised to monitor the oil level or potentially conduct an oil consumption test. I have not yet received a formal diagnostic or confirmation from Kia or a third party. Yes the vehicle was formally inspected by Gettel Kia of Bradenton on 14th Street for an engine stalling issue... Have experienced a stall only once since then Yes. The oil warning light turned on (and off several times in 1 minute intervals) for the first time around 132011 miles. Upon the mechanic checking the dipstick, the oil level was significantly below minimum. No check engine light appeared. An oil change was performed only 2133 miles since the last one. Additional Notes: I have discovered multiple similar reports from other 2016–2020 Kia Optima owners via online forums such as Reddit and Kia owner groups, suggesting this may be a widespread issue related to the GDI engine design. These cases often go unresolved until engine damage occurs. I am requesting: A formal oil consumption test A full engine inspection Repair or replacement if the issue is confirmed Consideration for goodwill or warranty extension due to potential manufacturing defect I am maintaining oil top-off records and would be happy to provide them

Got an oil change, and they advised that it was low on oil. (I had just replaced it recently) I took it to the dealer and they advised a part was bad, that they replaced. I was driving and the check engine light and oil light came on . I had to tow car. Dealer said the engine was burning oil, and that the engine is covered, but I would have to drive it until it got worse.

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.

Subject: Urgent Request for Engine Replacement – 2018 Kia Optima Dear Kia Consumer Affairs, I am writing to formally report a recurring and increasingly dangerous engine issue with my 2018 Kia Optima, and to request immediate assistance, including consideration for an engine replacement due to ongoing safety and reliability concerns. Since June 2024, I have routinely visited the Kia dealership on a near-monthly basis for service due to persistent problems with excessive oil consumption and spark plug failures. Each visit has resulted in service-related expenses, despite my efforts to maintain the vehicle in accordance with manufacturer recommendations. Unfortunately, the issue has not been resolved and continues to worsen. Most recently, on [XXX], I experienced a critical incident. While driving, the engine began shaking aggressively, the check engine light illuminated, and smoke was detected coming from the engine compartment. Out of concern for my safety, I immediately pulled over and had the vehicle dropped off at a nearby garage for emergency inspection. This incident, combined with the repeated monthly service visits and associated costs, clearly indicates a systemic issue that may be linked to known engine defects in similar Kia models. I urge Kia to review my case for warranty coverage, recall eligibility, or goodwill engine replacement assistance. I have attached supporting documentation including service records, receipts, and oil consumption logs. Please advise on the next steps for resolving this matter. Thank you for your attention. I look forward to your prompt response. Sincerely, [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My paint has begun bubbling up and feeling out of nowhere. I’ve always taken good care of my car yet spots are beginning to pop up along the passanger side. The paint continues to peel more as time goes on. I’ve found many complaints online of people saying they’ve had the same issue with their kia in the Snow White Pearl color I have, but there’s no recall and kia refuses to pay for it.

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.

Car consumes a lot of oil. Approximately 5 quarts per week-faulty engine parts allowing oil to seep into the combustion chamber. The oil is then ignited along with the fuel, creating blue-tinted exhaust smoke. It is burning out spark plugs which is then wearing them out and almost caused car accident when car started sputtering and would not barely go once pressing gas. Has been inspected by KIA dealership. Was told engine needs to be replaced-warranty expired and nothing can be done. Car only 2 years old when this problem started and they will not replace.
