2021 Kia Soul

The contact owns a 2021 Kia Soul. The contact stated that while driving approximately 80 MPH, the vehicle unexpectedly stalled, with the check engine warning light illuminated. The vehicle was restarted; however, the failure reoccurred. The contact stated that while driving uphill, the vehicle failed to accelerate as needed. The vehicle was taken to the dealer, where it was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and case was opened. The approximate failure mileage was 41,000. The VIN was not available.

I am writing to formally report a failure by Classic Kia of Streetsboro to provide the federally mandated safety remedy under Recall SC336 for my 2021 Kia Soul (VIN: [XXX] ). I have reason to believe the dealership has bypassed the mandatory safety protocols by intentionally omitting my documented diagnostic data—specifically Codes P0014/P0017, engine stalling, and excessive oil consumption—from the Techline Case Narrative. Evidence of Non-Compliance: 1. Improper Component Installation: Despite the documented timing failures, the dealership appears to have installed a Short Block (Part # 21102) instead of the required Long Block Assembly (Part # 21101-QQK). This leaves my oil-contaminated camshafts, valves, and VVT solenoids in the vehicle, posing a continued stalling risk. 2. Failure to Address Consequential Damage: The dealership is attempting to charge me a $99 "Customer Pay" fee for a catalytic converter back-pressure test. Under SC336, testing for consequential damage caused by a defective engine is the manufacturer's responsibility. 3. Withholding Documentation: The dealership has refused to provide the Techline Case Number or the Engine Part Number upon request, preventing me from verifying that the safety remedy was performed correctly. I will not be taking possession of the vehicle until Kia Corporate verifies that a Long Block Assembly was installed and that all diagnostic fees related to the recall symptoms are waived. This matter is currently being escalated but could definitely use your assistance. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

NHTSA SAFETY COMPLAINT: RECALL SC336 (CAMPAIGN 21V-301) NON-COMPLIANCE VIN: [XXX] I. PATTERN OF RECALL EVASION Vehicle (2021 Kia Soul) was towed to Classic Kia [XXX] ) on 3/13 with documented engine stalling, knocking, and codes P0014/P0017 (VVT/Timing failure). The dealership withheld this data from Kia Techline for 13 days (3/13–3/26), delaying the safety remedy until state authorities intervened. II. MECHANICAL IMPOSSIBILITY & REMEDY VIOLATION On Saturday 3/28, the dealer claimed a full engine swap was "installed and tested" in only 6.5 hours (7:30 AM–2:15 PM). Per the SC336 mandate, a compliant Long Block assembly (Part # ending in QQK) requires extensive fluid flushes, software reflashing, and safety recalibrations that cannot be performed correctly in this window. I suspect a "Short Block" shortcut was taken, reusing contaminated components in violation of the federal safety remedy. III. FRAUD BY OMISSION & UNIFIED SAFETY HAZARD The dealership is demanding a $99 "diagnostic fee" for an exhaust back-pressure test. Under SC336, testing for "consequential damage" (clogged catalytic converter) caused by the recall defect must be covered by the manufacturer. By omitting the stalling/timing symptoms from the initial Techline report, the dealer bypassed the mandatory exhaust safety testing. Reusing oil-contaminated VVT solenoids, camshafts, and valves from the failed engine poses an immediate fire and safety hazard. IV. DEMAND FOR INVESTIGATION I request NHTSA oversight to ensure Classic Kia provides: 1. Proof of Long Block (21101-QQK) installation vs. unauthorized Short Block (21102). 2. Time-stamped DEVT and GDS Full System Scan logs from 3/28. 3. Verification that all contaminated components were replaced, as a partial remedy leaves the vehicle in a hazardous state. Reusing oil-soaked VVT/cams & skipping exhaust tests creates a fire risk. An incomplete remedy violates SC336, leaving the car a high-risk liability for fire & stalling.

DEALER ADMISSION OF NON-COMPLIANCE: I am updating my complaint to document that Kia of Streetsboro is officially refusing to perform the mandatory mechanical inspection required by Recall SC336. Despite the vehicle suffering from "Loss of Motive Power" (stalling in traffic) and "Abnormal Engine Noise," the dealership’s service department stated via text on March 17: "I asked my manager and he said as of right now since your vehicle passed the tablet we cannot do anything else." The dealer further stated: "I suggest calling consumer affairs since you have an open case and letting them know what's going on and seeing if they can help." TECHNICAL VIOLATION: The dealer’s refusal based on a "tablet pass" is a direct violation of TSB SC336, Step 18c, which states that if a vehicle exhibits mechanical symptoms that "contradict a PASS result," the dealer MUST open a Techline Case for further instructions. By their own admission, the dealer is choosing to follow a "manager’s" opinion rather than the Federal Recall Protocol. They are attempting to release a vehicle that is actively stalling at intersections, which they define as an "Early Warning" system success, while ignoring the actual mechanical failure (the stalling). SAFETY RISK: This is a documented Ineffective Remedy. The dealer is punting the safety diagnosis to a "Consumer Affairs" call center rather than performing the borescope and Techline escalation required by the NHTSA. I am reporting this dealer for knowingly attempting to return a stalling, unsafe vehicle to a consumer while claiming the recall is complete.

My 2021 Kia Soul is exhibiting a severe safety defect documented in Recall SC336: frequent, unpredictable stalling in traffic ("Loss of Motive Power") and audible engine knocking. These symptoms create a high risk of a rear-end collision or being stranded in a dangerous traffic situation. The vehicle is currently at Kia of Streetsboro. Despite being provided with evidence of these active mechanical failures, the dealership is attempting to "remedy" the safety recall based solely on a "Pass" result from the Piston Ring Noise Sensing System (PNSS) software diagnostic. As the TSB SC336 notes that the root cause is physical damage to cylinder walls caused by defective piston oil rings, a software diagnostic "Pass" is not a physical repair and does not address the existing mechanical stalling. I have not received any status updates or communication from the dealership service department since Friday. The dealership is refusing to perform a borescope inspection or open a Kia Techline case to investigate the stalling, effectively denying a proper safety remedy. I am reporting this as a failure of the manufacturer and dealership to provide a safe and effective remedy for a known life-safety defect. The car remains unsafe to drive.
