SUSPENSION, EXTERIOR LIGHTING, ENGINE
My KIA Soul 2018 caught on file while driving. The whole engine was in flames. I didn't want to die because my car has a manufacturing issue that KIA was not aware about. The dealership I've purchased the car from denied to give me a copy of the mechanical inspection done at the dealership Stonebriar Chevrolet in Frisco, TX. The flames started under the car and made its way to the engine, smoke was coming from the AC vents. People were able to put the fire down before it got to the gas tank. Due to the seriousness of the damage, the car stopped working and we left it on the side of the road.

The contact was informed that the engine needed to be replaced. The vehicle was not repaired. Upon further investigation, the contact related the failure to NHTSA Campaign Number: 20V750000 (Engine); however, the VIN was not included. The manufacturer was made aware of the failure.

ENGINE
The engine seized up at 165,000 miles. According to one [XXX] at Trinity Automotive in Fairfield, Ohio, it's a known issue. According to [XXX] at PrebCo in Eaton, Ohio, the issue is related to low-pressure piston rings. Compression tests showed between 0 psi in one cylinder and between 55 and 58 psi in the other three cylinders. These issues have been verified at Matt Castrucci Service Center. With a GDI engine, I had been chasing down the usage of too much oil for several months. I get oil changes at 3,000 miles, and I would be 1/2 quart to 1 quart low at 3,000 miles. Dealership service staff in Beavercreek, Ohio, said that Kia considers the usage of one additional quart of oil per 1,000 miles to be "acceptable" - that makes zero sense. I was told that they would do a piston soak, and they directed me to a formal procedure on Kia's website. I used this process, and it definitely cleaned out all of the carbon. This did not fix the issue. Taking my youngest daughter to a dinner following her high school national honors society induction, I experienced an engine knock as I accelerated onto the I75 north. It felt like a strong jolt back. The 2018 Kia Soul Plus has been a 3,100-pound roadside decoration since November 2025. I still owe $14,000 on this loan, and I cannot afford an additional car payment. Replacement of the engine will be $8,500. Kia customer service told me this is an out-of-pocket expense as their warranty ended at 150,000 miles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

ENGINE
ENGINE SHUT OFF WHILE DRIVING IT DOWN THE HIGHWAY Purchased 8/5 from reseller, who had driver it over 200 miles with no issues. Had it inspected that day and no issues found. Scheduled appt w/ Clay Cooley Kia to drop off 8/12 to have warranty recalls addressed. Clay Cooley inspected and found no issues, verified in good shape; work completed 8/14. On 8/18, after driving it less than 183 miles, the vehicle COMPLETELY SHUT DOWN on the highway. The check engine light came on immediately before the car shut down, but that was all. It was incredibly dangerous. Searched online and discovered that this has been a know issue with Kia Souls. Discovered online that this was a known issue, and had previously been the focus of a class action lawsuit. Contacted Kia corporate who mandated I take it back to Clay Cooley Kia. Clay Cooley Kia refused to repair it, and Kia Corporate refused to handle further.

AIR BAGS, UNKNOWN OR OTHER
I am submitting this complaint regarding failure to complete a federally mandated safety recall and the subsequent release of my vehicle in an unsafe condition after prolonged dealer custody. Vehicle Information provided above Safety Recall Information Recall Type: Federal airbag safety recall Recall Notice Received: 2023 Summary of Safety Concern I delivered my vehicle to authorized Kia dealerships for completion of a federally mandated airbag safety recall. The vehicle remained in dealership custody for approximately seven months without completion of the recall. During this period, the dealerships demanded payment for diagnostics and asserted that recall-related issues were “warranty-related” or “customer responsibility,” which effectively blocked completion of the safety recall. Despite my continued communication and willingness to proceed with recall repair, the recall was not completed. Kia declined to authorize repairs necessary to complete the recall. Vehicle Released Unrepaired and Unsafe The dealership ultimately demanded that I remove the vehicle without completing the safety recall. Upon retrieval of the vehicle, I discovered: Missing and/or altered vehicle components Extensive interior water damage These conditions were not present when the vehicle was delivered and occurred while the vehicle was in the dealership’s exclusive custody. The vehicle was released in a materially worse and potentially unsafe condition. Ongoing Safety Risk The federal safety recall remains unresolved. Electrical systems and safety components may be compromised. The vehicle is currently unsafe to operate, and repair is no longer a reasonable remedy. Basis for NHTSA Review This complaint concerns: Obstruction and noncompletion of a federal safety recall Improper conditioning of recall repairs on payment Release of a recalled vehicle without repair Potential compromise of safety systems while in dealer custody

AIR BAGS, ELECTRICAL SYSTEM
A Kia franchise dealership demanded payment for diagnostics in order to perform a federal airbag safety recall, which I refused. After the dealer’s involvement, the vehicle’s diagnostic/OBD port became unreadable, preventing recall completion. A second Kia dealer states they cannot complete the recall and wants thousands of dollars just to attempt diagnosis. The vehicle has been out of service for over six months with an open safety recall. I believe the recall process has been obstructed.

STRUCTURE:BODY
The clear coat peeled off of the driver and passenger side mirrors in the beginning of 2024. The white paint started chipping off in a one inch straight line where the red roof meets the white side panel on both sides. You can tell it is where a strip of tape was that maybe separated the two paint colors in the process of painting. This began at the end of 2024. Then in early 2025, the white paint on the hood started flaking off in random spots all over the hood of the vehicle. The paint is completely gone in those areas and the gray body is now showing through where the white paint used to be.

ENGINE, POWER TRAIN
Description of the Problem: My 2018 Kia Soul has a recurring and unresolved safety issue involving sudden loss of power while driving. The check-engine light repeatedly comes on, and at times the vehicle will hesitate or lose acceleration unexpectedly, creating a risk of being unable to maintain speed in traffic. Chronology: This issue has been occurring for over a year. I have taken the vehicle to the Kia dealership multiple times for the same problem. Each time, the dealership has either been unable to diagnose the cause or has returned the vehicle stating the issue was repaired, but the problem returns within weeks. Most recently, the dealership kept the vehicle for over a month and still could not identify or resolve the cause of the power loss or the recurring check-engine light. They then instructed me to pick up the car and drive it until the warning light comes back on, despite my reporting that the vehicle loses power while driving and is unsafe to operate. Safety Concern: The loss of power happens without warning and can leave me unable to accelerate or maintain speed. This has made it unsafe to drive in normal traffic conditions, such as merging onto highways or crossing intersections. I cannot safely operate the vehicle in its current condition. Attempts to Resolve: All service has been performed at the same Kia dealership since the car was purchased new. Despite multiple repair visits, including a month-long stay at the dealership, the problem remains unresolved. Kia Customer Care has been contacted, but the issue continues with no effective resolution or repair. Reason for NHTSA Complaint: Because the malfunction involves sudden power loss and repeated failure of the authorized dealership to diagnose or repair the issue, I am reporting this as a potential safety defect. I am concerned that this may reflect a broader problem affecting this vehicle model.

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.

ENGINE
On 8/12/25, my 2018 Kia Soul (approx. 126,000 miles) suddenly began shuddering at low RPM with a flashing check engine light, near-stalling, and smoke from the exhaust. A warning message appeared for an engine control issue. Prior to failure, the engine intermittently knocked and displayed an oil pressure warning light. The engine burned oil at an excessive rate between routine oil changes. At the Kia dealership, diagnostic codes P0300 and P0303 were found. The dealer reported a burnt valve and seized starter, estimating $2,960 for valve repair or $6,437 for engine replacement, and stated these were not covered under Kia’s extended warranty or E2 Class Action Settlement because no P1326 code appeared. However, the symptoms match the rod bearing wear defect already covered under the E2 settlement. The dealer refused to perform the bearing clearance test (Kia’s required diagnostic for this defect) without payment, even though the settlement and extended warranty specify Kia must cover all inspection, diagnostic, and repair costs for potential rod bearing failures within the 15-year/150,000-mile coverage period. The engine failure created a serious safety risk when the vehicle lost power and nearly stalled in traffic. The burnt valve and seized starter are likely secondary effects of bearing-related long block failure. Kia’s refusal to inspect the vehicle without charge contradicts the settlement’s intent and prevents proper diagnosis of a known defect. I request that NHTSA investigate Kia’s handling of inspection and warranty coverage for vehicles showing these symptoms but lacking code P1326.

Low compression on cylinder 3 and 4 and the car only has 40,000 miles on it. It's not covered in warranty because it's a 2018 model but I've only had the car for 1.5 years and still owe 18,000 on it and I'm a officer and a single mother and can't afford to let the car go back when Kia knows these cars have engine issues and low compression engine problems.
