KIA Complaints

My 2016 Kia Soul (1.6L GDI engine) experienced a catastrophic, sudden engine failure while driving, preceded by Check Engine Light code P0420 (Catalyst System Efficiency Below Threshold). This exact failure sequence is the precise subject of active NHTSA Safety Recall Campaign 19V120 (Kia Campaign SC176).Although the vehicle received the mandated SC176 preventative software update in 2019, the underlying mechanical defect was not cured. High exhaust gas temperatures caused the catalytic converter to degrade and fracture internally. The fractured abrasive substrate particles were then siphoned backward into the engine combustion chamber during normal valve operation. This caused immediate, severe scoring of the cylinder walls and piston damage, leading to total engine seizure and failure. This defect presents an extreme safety risk. Sudden engine failure at highway speeds causes an immediate loss of motive power, braking assistance, and power steering, significantly increasing the risk of a high-speed collision. Furthermore, fractured connecting rods or oil leakage stemming from this specific engine failure pose a severe vehicle fire hazard. The vehicle is currently held for diagnostic verification at Kia Riverside in California. I am filing this complaint because the manufacturer's 2019 software remedy was entirely ineffective at preventing the mechanical destruction of the engine and catalytic converter. I am requesting that the NHTSA hold Kia accountable to fulfill the physical repair and replacement mandates of Recall SC176 at zero cost to the consumer, regardless of the prior software logging.

Engine wiring is covered in soy based products which attract rodents as a source of food. Rodents then chew various wires and damage the electrical system. The check engine light has popped on twice in one year with both times requiring service repair for the chewed wires. There is a potential for electrical fires or other various failures due to rodents chewing through the wires. Kia has known about this problem for over a decade and continues to use soy based coverings in their engine without any mitigation for rodents.

Odometer Fraud. The contact purchased a 2014 Kia Optima. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 71,527. However, upon taking the vehicle to the dealer due to excessive oil consumption, the dealer informed the contact that the actual mileage was over 200,000 as per the Carfax report. The seller was contacted but did not provide assistance.

I received a voluntary emissions update letter from kia, and although it was voluntary, the letter said failure to update could be considered lack of maintenance. The update was performed on XXX at Dorsch Ford/Kia in [XXX]. The vehicle ran poorly from that day forward. I gave it a couple of weeks to insure that the system could learn my driving habits. I then went to the Dorsch service department to report my issues. The service writer {Andy} said he hadn't heard of any issues with the update. I had him log in my issues to have a record that I complained. I returned several more times and talked to other service writers who told me that if they would check the vehicle and found nothing that I would have to pay service fees. the vehicle jerks and up/downshifts frequently and almost stalls sometimes when accelerating from a stoplight. It will lung periodically when navigating a parking lot at low speeds. It frequently searches for a different gear in traffic. To be clear, my car ran perfectly before this update. I asked them to put the previous tune back into the car but they said they can't do that. The car runs fine sometimes but the uncertainty of the jerking and shifting at improper times makes it dangerous to drive. Also almost stalling at an intersection is very dangerous too. I doubt that I am the only one to have this problem. Please help in any way you can to get this fixed without me having to spend money to correct a factory/dealer initiated problem Thank you for all your help.

I bought this car February 2026 when I drove it on the freeway they car felt wiggly not the axle is broke and the wheel bearings stop the car from going

I was driving when the vehicle stalled while slowing down. It stalled several more times at a stop light, and then when slowing down or accelerating slowly. I then noticed the engine started making a noise. I have parked it and not been able to drive it since. No safety indicators popped up during the stalling. When the engine started making a noice the check engine light then turned on. The car has only 65958miles on it. I believe it should be apart of the SC209 recall list but it is not.

Initial Breakdown: July 2024, my 2021 Kia Soul (under 40,000 miles) idled roughly and stalled while in motion. It restarted, but as a precaution, I towed it to Kia Greenbrier Chesapeake while it was operable. After diagnostics, the vehicle would no longer start. Warranty Denial: The dealer blamed engine sludge from two missed oil changes in 2022 and quoted $10,000 for a new engine. In August 2024, I appealed the decision but was denied (Exhibit A & B). There were no recalls active for the 2021 model at this time, but there were recalls for the 2018-2020 models for identical symptoms. Third-Party Repair: I paid $3,017 out of pocket to an independent shop for a new timing assembly to make the vehicle safe and drivable again (Exhibit C). Because my daughter is disabled and requires transportation, getting repairs was imperative. A new valve kit, fresh synthetic oil, and filter service were completed by the third-party repair shop. I also returned to Kia Virginia Beach for several subsequent oil changes (Exhibit D). In April 2025, Kia Corporate issued an official safety recall for my exact vehicle (Exhibit E). Before that, in March 2025, I attempted to have the newly issued recall (25V-099) performed, but the dealer turned my vehicle away, claiming a lack of parts. Final Failure: In May 2025, the night before a rescheduled recall appointment, the car became permanently inoperable (at only 47,500 miles). Due to extreme financial hardship and health concerns, I am without my vehicle and without an option. Complaint: The Kia dealership refused to perform the safety recall remedy, verbally citing the same 2022 maintenance gaps from the previous year. The dealership violated federal recall regulations for a known defect. I was left stranded, resulting in a financial charge-off of my auto loan.

My sunroof windscreen arm broke which in turn caused the glass to go off track. The windscreen arm is a known issue! But there is no recall. I SHOULDN'T HAVE TO PAY $7000 to fix a known problem!

My 2019 Sorento 3.3L suffered high oil consumption followed by a severe oil leak at the back of the head/engine block threads. There is an odor of coolant which smells sweet with no visible coolant leak meaning there is likely coolant seeping into the engine mixing with the oil. I believe this an ongoing engine failure caused from Kia not correcting the issues over many years.

The contact owned a 2016 KIA OPTIMA. The contact stated that while driving at 30 MPH occupied with her husband the contact heard a noise coming from the rear of the vehicle and smoke coming from the rear of the vehicle as you looked in the drive side rear view mirror and while depressing the brake pedal attempting to come to a complete at the traffic light, the brakes failed to work a intended. No warning light illuminated. The contact mention she kept trying to depress the brake pedal, however the vehicle kept accelerating causing the vehicle to crash into a ditch, go around a telephone poll, crashing into a rock garden which allowing the vehicle to come to a complete stop. The vehicle was towed to a towing lot call interstate towing then the vehicle was then towed by insurance company to a collision center. No injuries were sustained. No medical attention. The fire department extinguished the fire. The contact stated a police report was filed. The vehicle was destroyed. The manufacturer was not made aware of the failure. The approximate failure mileage was 166,834.
