Pearl white paint peeling prematurely

ENGINE

Over the past couple years, the check engine light has came on and I immediately had a mechanic look at it. The first time they said it was my spark plugs and changed them. Then this year, a year later, the check engine light came on and it became hard to accelerate on my way to a mechanic. Once again, they said spark plugs, so they changed them and claimed that they didn't look to had been changed before. Now here I am a couple of months after that, my check engine light came back on and my car started making a funny noise on my way to work. I turned back around and went home since I was closer to home than work. It sounds like rocks popping when you start it or hit the gas. I had someone check the codes and it said engine 1 and 4 coils. All 4 coils and spark plugs were changed again. That did not fix it. The sound is still there and the engine light is now blinking. I have kept up with the oil changes and everything. There is no recall. I still owe on the car and it is not able to be driven.

FUEL/PROPULSION SYSTEM

I was just driving then noticed lack of acceleration and the engine light flashing. Loosing acceleration mid driving posed a great safety risk because no other drivers would know the issue I was experiencing and risked causing an accident. The vehicle was taken for a fault code reading which indicated a knock sensor code, later it was inspected at the dealership who confirmed an ECU issue. The police or insurance have not inspected the vehicle for this particular issue.

STRUCTURE:BODY

I am the owner of a 2019 Kia Optima SX Turbo in Snow White Pearl (SWP) paint. At approximately 100,000 miles, I observed bubbling and peeling of the paint—no collision or exterior impact occurred to trigger this. The peeling area has since enlarged, exposing the underlying primer or bare metal, which is visible in an attached photo. I contacted Kia around 115,000 miles when I fully realized the paint failure. Kia declined to offer any repair or goodwill assistance, citing that the vehicle is no longer under warranty. However, this is a widely reported defect affecting many Kia and Hyundai vehicles with the Snow White Pearl paint. Numerous owners have experienced similar peeling and flaking without misuse or accidents. This is clearly a manufacturing defect in paint adhesion, rather than normal deterioration. It compromises both the vehicle’s aesthetics and resale value, and it may lead to rust or more serious long-term problems. There are pending class-action lawsuits in Canada for identical issues with SWP paint. Yet, U.S. owners are left to manage this defective condition on their own, without support from Kia. I respectfully request the NHTSA open an investigation into this paint failure issue involving Kia vehicles painted in Snow White Pearl, including the 2019 Optima, and consider issuing a recall or a mandatory repair campaign.

ENGINE

I am the owner of a 2019 Kia Optima FE with the 2.4L GDI engine (Theta II). Despite following a consistent maintenance schedule with synthetic oil changes every 4,000 to 6,000 miles, the vehicle is experiencing premature engine failure. Specifically, the engine has internal valve damage, and the shop diagnosed the issue as failure of an internal valve component. The vehicle also has a leaking axle inner boot, but the major concern is the engine. Kia has refused warranty coverage, goodwill assistance, or recall support despite this engine being part of a long-standing pattern of issues documented across many Kia and Hyundai vehicles with the Theta II platform. I still owe approximately $10,000 on this vehicle, and now face a potential $5,000+ repair due to a known manufacturing defect. Kia Consumer Affairs and the dealership both declined assistance, claiming my warranty has expired, even though this engine has been involved in class action lawsuits, extended warranties, and TSBs related to premature wear, oil consumption, and mechanical failure. I am submitting this complaint to formally report the issue and to urge the NHTSA to continue investigating Kia’s 2.4L Theta II engine failures, as they represent a potential safety and financial risk to consumers. Many drivers are left stranded or in serious debt due to an engine defect they could not have prevented.

Engine failure

ENGINE

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

I purchased this car off the show room floor in 2019 with only 10 miles on it. At some point in 2022 my car was slow to accelerate. I received the recall letter September 16,2022. no appointments until 08/09/2023. It didn't help .It was still stalling two weeks after. I have talked to the manager numerous occasions. He said it sounds like the transmission. The parts manager told me he will keep it overnight so his mechanics can drive it the following morning. That didn't happen. This car is a safety hazard. I can't pull out in front of anyone due to the car stalling. My family like to have lost our lives this weekend 05/31/2025 due to the car failing to accelerate(stalling). I have filed complaints with KIA head quarters twice. They keep telling me that if there's no warning lights on they can't identify the problem. On 01/06/2025, the manager and parts manager agreed to keep my car for a couple of days. I paid for my oil change/tire rotation and they sent me on my way. the bottom line is this car will be the death of me. God forbid!!

Original owner, received in mail that this vehicle was recalled for engine issues. Provided a lifetime warranty for engine. Noticed my vehicle began consuming oil more than normal. I constantly have to put oil in the car 2-3/ week. The shops say it doesn’t need an oil change the oil is burning fast. Never notice any leaks bit my vehicle began to not pick up speed and shop said the oil is burning and possible engine is getting ready to go. Called dealership and they said they won’t replace u less the engine is totally blown and I need to have all type documents showing I’ve been doing maintenance although this is a known issue. Constant oil changes.

I own a 2019 kia that is garage low milage 35,757 when not driving. the paint had a spot of paint missing on the hood and i ordered touchup paint to protect and before it arrived i noticed a larger spot. I drove to town and a large spot flaked. I call the dealer and they said they didn't handle that. I called kia customer service and they said would write a work order and i haven't heard any thing from them. i have gone to computer to see if any recalls and none. there are a lot of complaints from owners but no help from Kia . I read an article from Kia that they had stopped using the pearl white paint due to so many complaints. This need to be address and something done. I took to a reputable body shop today and received estimate and it was not just my hood found spots on right fender and trunk with estimate of almost $4,000.00 . I can not make Kia repaint my car and i can not leave it to rust nor can i afford a new car. Canada did recalls on this matter the United States needs to stand up for the people of the United States.

The contact owns a 2019 Kia Optima. The contact stated that while driving at various speeds, an abnormal engine oil consumption was noticed. The check engine oil warning light illuminated abnormally often, shortly after an oil change had been performed. The vehicle was taken to a local dealer, where it was diagnosed with defective piston oil rings. The vehicle was not repaired due to the warranty being deemed invalid. Upon further investigation, the contact related the failure to an unknown recall; however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 65,000.

ENGINE

My engine is burning oil at an alarming rate, my car is not recognizing low oil, so I no oil lights are appearing. I have to go to the oil change place weekly to have my oil checked. When my oil is low, I have to pay to have my oil replenished between months of my oil changes. My and my son safety was put at risk, when I found out at an oil change visit, I had less than an quart of oil I was driving around with. Which can cause engine failure while driving, overheating, and reduced performance while driving. This was confirmed by an oil change facility. I am currently in a ongoing dispute with the dealership I received my car from. The Kia dealership is refusing to do any maintenance until I can produce five years of oil change records that are not showing on car fax. To date my car oil light is not coming on, no signs are shown in my car showing this issue. I have to just get it checked weekly and pay for oil to be safe until, I can get a new engine.

AIR BAGS

I brought my Kia Optima into the dealership in October 0f 2024, because my airbag light came on. It has not been there over 6 months because my passenger airbag module is not operable and rending all my airbags useless; it is also on backorder with no ETA. The dealership wouldn't help with my escalation it has taken me 6 months to get to the escalations department and now they will not offer additional support with payments or a buy back "due to warranty". I feel helpless and like my investment has been thrown in the trash and lit on fire as my car is sitting in the parking lot in the AZ sun, not being moved and not protected from the elements. They continue to offer no real resolutions and tell me to wait for a piece that has absolutely no ETA.

Most recently the starter went bad, alternator, and battery. Replaced with a second brand new battery and car won't start again. Dash is lighting up erratically, new battery dead. As if something is drawing all power and draining brand new batteries. This car has a little over 86,000 miles and one thing after another is failing. The car lost power and power steering in a curve leaving us in a dangerous situation after replacing the starter. Dash lighting up erratically with front end collision warning message on the display. We had it towed to our residence which our auto insurance reimbursed us for. Replaced alternator and battery yesterday, and the car lost all power again turning back onto our street, again with the Dash lighting up erratically.

My 2019 Kia Optima purchased brand new. Kia released a service bulletin on 3/1/22 citing “excessive oil consumption for 2011-2021 Optima's”. I took it in for the "updates" for said service bulletin for the engine and was told that my engine is good and covered now for the life of the engine even past the 100k miles (mind you no one mentioned doing an excessive oil consumption test at this time). On 3/22/24 car had 104k miles on it and the oil light came on. I had an oil change just 2500 miles or so prior. Pulled into an autozone and it was almost bone dry. I put oil in it and the light went off. I took it to Evans Kia and was told that they couldn't do anything because it was past 100k warranty and that they couldn't run the DX test to determine if it was excessively consuming oil as per the recall. Apparently during the recall they did the DX tests if the consumer stated it was burning oil fast or something to that extent. Mine did not get said test, only the upgrade. They should have done the test, but they just did an "upgrade" which clearly did not work. They said since I had the "upgrade", if the engine fails, then Kia would fix it under warranty. Since then, this happened at least 4 more times with the oil light coming on and engine oil practically gone. Each time took less and less miles. I showed up to Kia 2 of those times in 2024 to show them the the oil change date, mileage, and check oil light on. Also physically showed them the oil being almost empty, yet they did nothing but say when the engine dies or "knocks" they can fix it under warranty. One of those times I had it towed but they determined it was the fuel pump, never mentioned anything else. Fast forward 3/15/25 the engine starts knocking and engine light comes on. I managed to drive it to Evans Kia without any accidents. After my car sat for 9 days, they call me on 3/25/25 and tell me there is a "burnt valve on cylinder 4 and the engine will need to be replaced and it is not covered. How? Help!
