KIA Complaints

For about 23,000 miles our mechanic has mentioned that the engine is burning oil. The exhaust pipe is covered in black soot. I monitor the oil level and it is always low even after oil changes with no oil leak. This has been provided to Kia with no remedy. Recently our Sorento was in a busy highway and the check engine, oil and battery lights came on and the car went into limp mode. We had the vehicle towed to Kia Chula Vista and the engine will be replaced by them. My concern is that the catalytic converter will soon fail and the engine issues need to be addressed for all of these makes/models before someone gets seriously hurt or killed.

I was driving on the freeway steady at 72mph and the car suddenly accelerated on its own. It hit 90 within seconds and I had to step on the break for the car to slow down.

The safety hazard began with a pattern of ignored warnings by the authorized dealer network. On Aug 15, 2025, I brought the vehicle to Luther Kia of Bloomington for a Check Engine Light. The dealer simply cleared the code without diagnosis, failing to catch early signs of engine trouble. On Sept 22, 2025, the engine failed again. I drove the vehicle in unsafe "limp mode" to Luther Nissan Kia [XXX] ). They found the engine was "4 quarts low on oil" (severe starvation just 37 days after a dealer oil change). Despite this catastrophic finding, they failed to diagnose the root cause and released the unsafe vehicle to me after selling only a spark plug replacement. On Sept 26, when I attempted to pick up the vehicle, the Check Engine Light was flashing immediately at handover. I refused to take the unsafe vehicle. The dealer then replaced an Oil Control Valve (OCV) and released the vehicle to me again later that day. After this second "repair," I drove the vehicle for only a few miles before the engine failed again with a Check Engine Light. The dealer has since admitted in writing (BBB complaint #XXX) that the engine was "deprived of lubrication" due to the initial low oil condition. By ignoring early warnings and releasing a vehicle with a dying engine twice, the dealer put me and other motorists at risk of a sudden loss of power at highway speeds.

9/25/25 Car would not accelerate on exit ramp and engine seized just as I pulled into Romeo Kia Kingston Car Repair Center, causing a dangerous driving situation. No prior noise or warning lights for the 6 years I have owned the car. 10/6/25 per Jared Illg, District Kia Mgr., “Although, my 2018 Kia Soul 2.0 engine is under the Class Action Settlement, my car is not under extended warranty, because I did not have the KSDS software update.” I did not receive any mailings over the years, but two August, 2025 re-notifications. •Kia KSDS software 2018 update (172/953), why wasn't update performed by Romeo Auto Group Dealership before I purchased car? •Kia’s parent company, Hyundai Motor Group removed the KSDS update requirement for its lifetime engine warranty, why hasn’t Kia? •The Romeo Auto Group Dealership owned this car and used it as a Lease Car. I am second owner, why didn't I get a Transferable / Powertrain warranty? •Why would I get a limited warranty knowing the Kia Soul has faulty 2.0 engines since 2012, defects that arise in the car that originate from the factory; resulting in numerous lawsuits and class action settlements. This is not a case of owner neglect; I have taken excellent care of my 2018 Kia Soul. •I did not receive TSB-19 and TSB 222 which refers to known defects of all these connected components: excessive oil consumption, defective piston rings, and rod bearing failure; resulting in catastrophic engine failure. My mechanic has installed a used 53,000 mi. used engine. I now have a debt of $8,817.91 for a 2018 Kia Soul I have owned for six (6) years. I am so stressed this has a disastrous impact on my financial situation. Desired resolution: I am asking for Kia America, Inc. to reimburse me my expenses of $8,817.91 (replacement engine, towing, and car rentals; attached) and provide the extended Warranty for 150,000 mi.

Vehicle: 2016 Kia Sorento, VIN [XXX] Incident Date: November 13, 2025 Incident Location: Durham, NC (3828 Guess Rd) Cause of Loss: Engine Fire, confirmed by Durham Fire Department Report (Incident #253663) as "originated from under the hood." TECHNICAL NARRATIVE & SYMPTOMS (CRITICAL FOR LIABILITY): I am filing this complaint to report a catastrophic vehicle fire that I believe is directly linked to multiple acknowledged manufacturing defects that create a fire risk in Kia vehicles. ABS/Traction Control Light Warning (Direct Fire Risk Symptom): Immediately prior to the loss, the ABS and Traction Control warning lights were constantly illuminated. This is a known precursor symptom for the defective Hydraulic Electronic Control Unit (HECU) or ABS Module short-circuit, which has been cited in numerous Kia fire recalls (e.g., NHTSA 20V019, 20V519). The fire's origin under the hood is consistent with this component failure. Prior Engine Failures (Systemic Defect History): This vehicle has a history of catastrophic manufacturing defects: The engine assembly was replaced in 2023 due to the known Theta II Rod Bearing Failure. The knock sensor was replaced in September 2025 as part of the KSDS Product Improvement Campaign, demonstrating the vehicle was still under active service for critical engine monitoring defects just weeks before the fire. Potential Tow Hitch Wiring Fire Risk: The vehicle was fully engulfed, but the fire may also be linked to the defect cited in NHTSA Recall 22V703 (tow hitch wiring harness short circuit, which also poses a fire risk). I require a full investigation into this defect leading to compensation for the total loss of the vehicle and consequential damages.

Engine oil consumption issue. Engine is run dry due to overconsumption of oil, increasing likelihood of cracked engine block or engine fire. Secondary issue includes increased fuel consumption/ decreased MPG. First oil consumption test reflected 60% of oil used 1,000 miles after oil change.

Subject: RECALL VIOLATION: Kia on the Boulevard (Philadelphia) - Refused Remedy, Charged $199, Returned Unsafe Vehicle Vehicle Information: [Year] Kia Optima Hybrid Dealership Name: Kia on the Boulevard Dealership Address: 11295 Roosevelt Blvd, Philadelphia, PA 19154 Complaint Description: 1. The Safety Incident: While operating the vehicle, I experienced a catastrophic engine failure. Thick smoke poured from the engine compartment, followed by immediate stalling. This presented a severe fire risk and safety hazard. 2. Dealer Misconduct & Illegal Charges: I towed the vehicle to Kia on the Boulevard (11295 Roosevelt Blvd, Philadelphia) for the active engine recall remedy. The dealership: * Refused to perform the recall repair free of charge. * Forced me to pay a $199 "diagnostic fee" just to look at the recall-related defect, which should be covered by the manufacturer. * Threatened me with $45/day storage fees if I did not pay the $199 and remove the vehicle immediately. 3. Current Status: Under the threat of accumulating storage fees, I was coerced into paying the $199 and towing the vehicle back to my residence. The dealership knowingly released a vehicle with a catastrophic engine failure (smoke/fire risk) back to the owner without performing the federally mandated remedy. The unsafe vehicle is now sitting at my home unrepaired. 4. Conclusion: I request an immediate investigation into Kia on the Boulevard's refusal to honor the recall and their practice of charging customers for recall-related inspections.

My 2023 Kia EV6 experienced a sudden ICCU and 12-volt system failure while traveling approximately 50 mph. Without warning, the vehicle instantly lost propulsion and all electrical power. This included loss of steering assist, braking assist, hazard lights, shift capability (unable to shift into Park), and even the ability to lock the doors. The failure effectively “bricked” the vehicle in motion. I was only able to get the vehicle off the roadway because the road happened to slope downward into a nearby lot. Steering required significant physical effort, the brake pedal went completely hard (“dead”), and the vehicle offered no functional parking brake or Park engagement once stopped. Because I was on a hill, we had to allow the car to roll to the bottom until it met a curb to prevent movement. After power loss, the doors could not be locked at all. This type of unrecoverable electrical failure creates an extreme safety hazard for the driver, passengers, and surrounding traffic. There is no pre-warning and no diagnostic indicator. The ICCU fuse appears to fail spontaneously and renders the vehicle uncontrollable in several critical respects. This is not an isolated issue. ICCU failures have been occurring across the Kia EV6 and Hyundai Ioniq 5/6 platforms for more than three years, including on brand-new 2025 models. The persistence of this defect across multiple model years indicates that the underlying design or component defect has not been resolved by the manufacturer. Given the suddenness of the failure, the total loss of vehicle control systems, and the long history of similar incidents reported by other owners, I am now hesitant to drive the vehicle due to the unpredictable and dangerous nature of the defect.

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.

Incident #1: [XXX] The vehicle would not accelerate after coming to a stop at an intersection. The vehicle would not exceed 20 MPH with oncoming traffic from both the East and West as I was turning West from a North Bound Road. On coming traffic was traveling between 45 and 50 MPH. I was clearly nearly broadsided. The car displayed flashing lights on the dash as I was attempting to accelerate. Depressing the accelerator did not increase my speed. The car kept at a 20 MPH speed for the 1/2 mile I traveled to pull off the road in a safe location, causing traffic to be disrupted until I could pull off the highway I had the car towed to the Kia of Round Rock dealership November 17th. The car remained at Kia until December 3rd where they were unable to duplicate the problem. I requested the problem be referred to Kia in California. Kia of CA was totally unresponsive when the problem could not be duplicated. Incident #2 [XXX] Vehicle failed to respond to accelerate after stopping before attempting to enter a four lane highway. (No traffic was visible.) The car would not accelerate more than 20 MPR, the speed limit was 55 MPH. For the 1.5 mile trip home, I turned on my hazard lights, kept to the right and flagged traffic around me. The car never exceeded 20 MPH.
