ELECTRICAL SYSTEM,ENGINE,LANE DEPARTURE — Filed 03/17/2026

Problem 1, Check Engine Light: I purchased the used car on Jan 9 2025, around 23,400 miles from Kia Dealership, capitol Expy in San Jose. Today 05/27/2026, the odometer reads 26, 407 miles. My car is used only twice a week - 20 miles on Fridays, 12 miles on Wednesdays. My car has less than minimum wear and tear and is barely used. I completed my 25K service after Thanksgiving in Nov 2025. I have not even driven 1500 miles and the car is back in for service. Prior to this, within a month of purchasing my car Kia replaced the battery in my car. Around Mar 15, 2026, the Check Engine Light displayed. I called the Kia Dealership on Capitol Expy in San Jose 3-4 times, but they Kia dealership don't call back. On 05/15/2026, for the first time I drove about 50 miles return trip. While driving North on I-280 from [XXX] to [XXX] , over rolling hills that had some incline, the Check Engine Light came on.I scheduled service. I experienced that the vehicle struggle to climb the incline of rolling hills, after the battery charge was exhausted and the engine was running only on gas. The gas was 3/4 full. This is a safety hazard for me to be interrupted by Check Engine Light twice while driving and that too when my car has not even completed 30K miles. My car is sin Service on 05/26/2026 and in the shop for 3 days diagnosis. The Kia Dealership has yet to determine the problem. I have had to rent my own rental car even though I purchased Extended Warranty on the car. Problem 2, Blind Spot Warning Light on right side mirror: On 05/13/2026 and on 05/22/2026, the Blind Spot warning light on right side mirror does not display oncoming traffic when my car is parallel to the lane markings. On 05/13/2026, I was driving at 30mph and on 05/22/2026 I was stationary in the center divider. In both instances, the passing driver had to honk at me really loud -- to avert an accident. Both problems are severe safety hazards. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

UNKNOWN OR OTHER — Filed 05/04/2026

am writing to formally request assistance regarding my Kia vehicle which I purchased used at approximately 38,000 miles. Shortly after purchase, the vehicle became undrivable and has since required repeated repairs without resolution. To date, the vehicle has been presented for repair on six separate occasions for the same issue and has remained out of service for a significant period of time. Based on these repeated failures and lack of resolution, the vehicle may reasonably be considered defective at this point. Despite being unable to use the vehicle, I have continued to make monthly payments, resulting in considerable financial hardship. In an effort to resolve this matter, I consulted with a Maryland MVA investigator, who advised me to contact Kia directly and report that the vehicle appears to have been sold with a pre-existing defect. I have also communicated with the selling dealership, Eastern Motors; however, I was informed that due to changes in management, they are unable to provide further assistance and consider the matter outside of their control. Additionally, I have previously reached out regarding this issue and have not received a response. Given the timing of the failure, the repeated unsuccessful repair attempts, and the extended period the vehicle has been out of service, I respectfully request that Kia conduct a thorough review of this matter. I am respectfully requesting Kia’s assistance in resolving this matter. Specifically, I would like to explore options such as a replacement vehicle, repurchase (buyback), reimbursement of payments made, or other goodwill support. I remain open to a fair and reasonable resolution. Please advise what documentation or additional information is required to proceed. I am prepared to provide all relevant records, including purchase documentation and complete service history. Thank you for your prompt attention to this matter. I look forward to your response.

FUEL/PROPULSION SYSTEM — Filed 04/12/2026

Intermittent warning to "Refill Inverter Coolant" displays on the dash screen. This is a known issue pursuant to SA512 (ELE 270 Rev 3) due to faulty coolant that crystallizes and interferes with the sensor. However, per Kia, it is only covered under standard warranty (5 years/60k miles) and while my vehicle is within the year warranty, it is over the mileage. Quote was to replace "Chiller, water pump and flush coolant system" at a cost of $2369.02 including parts and labor. Dealership will not perform recommended maintenance of coolant flush (every 37k miles) without replacing these parts. If this was a known defect why is there a limitation to the SA? It should be covered as a recall, not a voluntary service alert. I am unable to properly monitor the in-dash warnings regarding coolant levels until this problem is fixed

The vehicle has a recurring P0420 code (“Catalyst System Efficiency Below Threshold Bank 1”). A boroscope inspection at Ricardo Caballero Kia Santa Isabel (invoice #[XXX] dated December 5, 2025) confirmed internal disintegration of the catalytic converter, with physical pieces of the catalyst falling out when the exhaust pipe was removed. This failure appears related to Recall 23V534 (SC276) and TSB PS709 (overheating / coolant boiling issues in 2017-2022 Niro Hybrid models). Motorambar, Inc. (official Kia distributor in Puerto Rico) has ignored my warranty claim since December 2 and December 22, 2025 (more than four months). Motorambar is now refusing to authorize a courtesy loaner vehicle at the dealer Ricardo Caballero Kia Santa Isabel, claiming the tests will take less than 5 days. This leaves me without transportation. The catalytic converter is fully covered under the Federal Emissions Warranty (8 years / 80,000 miles). I request that NHTSA investigate this as a potential safety and emissions defect and require Kia / Motorambar to: 1. Immediately repair or replace the catalytic converter under warranty at no cost. 2. Provide a courtesy loaner vehicle during the repair. 3. Reimburse previous diagnostic costs of $449.17.

Vehicle with code p0420, Kia dealership technician say: the problem was the spark, proceeded to change it and clear code. Check engine turn on again, the same person say: it’s a ring piston, the car was leaked engine oil to exhaust and he see blue smoke, no evidence for part of dealership and dealership never mention the car was consuming excessive engine oil.

EXTERIOR LIGHTING,SERVICE BRAKES — Filed 03/01/2025

What component or system failed or malfunctioned, and is it available for inspection upon request? -I have received a "Check Brake Light" warning several times now, even after replacing the bulbs. I have replaced them twice now in the past 6 months and the issue persists. I believe it to be a faulty sensor or something similar. Yes, it is available to inspect upon request. How was your safety or the safety of others put at risk? I do not know if my brake light is functioning properly as this warning indicator comes on intermittently even though the light has been replaced and even when it seems there is nothing wrong with the light. It is very stressful. Has the problem been reproduced or confirmed by a dealer or independent service center? I took my car to the dealership in November 2025 and they couldn't find any issue. The indicator light did not come on at the dealership but came on again later in the week. They even replaced both brake lights hoping that would help. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The dealership service center Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No other symptoms.

AIR BAGS — Filed 11/28/2025

I was driving on a 70mph hwy and traffic came to a full and sudden stop due to a car cutting across lanes a few cars ahead of me. There was no time for me to stop and I couldn’t see the traffic stopped. The car in front of me was able to stop without hitting anyone but I could not. Airbags did not deploy and this concerned me even though I was not injured.
