Kia Soul knocking problems

Filed Oct 30, 2026 · Engine · CA

Subject: Safety Complaint Regarding Kia Recall SC336, Excessive Oil Consumption, and Engine Knocking I am filing this complaint against Valley Kia regarding its handling of Recall SC336 on my 2021 Kia Soul S. I was informed by Valley Kia that the recall repair was completed in May 2025. However, on September 17, 2026, I returned the vehicle because of excessive oil consumption and engine knocking, symptoms consistent with the engine problems addressed by the recall. The dealership changed the oil, but within two weeks, the engine had burned through the oil again. I am concerned that the underlying problem has not been properly diagnosed or corrected. Valley Kia is refusing to adequately address the issue under the recall and is asking me to pay for repairs that I cannot afford. I rely on this vehicle to commute approximately 45 miles each way to work. I am afraid the engine could fail while I am driving on the freeway, potentially putting my life and the lives of other motorists at risk. I am also concerned about the possibility of an engine fire. I am requesting that the federal safety agency investigate this matter and help determine whether Valley Kia properly completed Recall SC336 and whether my vehicle's current engine problems require further recall-related repairs or other corrective action. I should not have to bear the financial burden of a potentially serious safety defect that may be related to a recall the dealership claims to have completed. Please review this complaint and advise me of the appropriate steps to protect my safety and resolve this matter.

2012 Kia Soul 1.6L GDI (VIN: [XXX]). Case #[XXX]. Safety Hazard Description: The vehicle experienced a sudden engine stalling event at highway speeds and repeatedly dropped into a restricted "Limp Mode" due to a recurring P1326 diagnostic code. This code is explicitly tied to Kia's Knock Sensor Detection System (KSDS) monitoring structural connecting rod bearing failure. The sudden loss of engine RPMs and throttle response created a severe traffic hazard, leaving me without power steering or predictable acceleration in active traffic. Dealer Information & System Non-Compliance: The vehicle is currently grounded and unsafe to drive. Southlake Kia (Merrillville, IN) verified that the vehicle's engine sensor and circuit are operating perfectly with an end-to-end wiring test reading at a flawless 0.2 OHMS (Repair Order #[XXX]). This mathematically confirms that the sensor is picking up real, severe internal mechanical vibrations from a failing engine block rather than an electrical short circuit. Official internal dealer records (R/O #[XXX]) prove that this severe engine defect initially manifested and was documented at 149,715 miles—strictly under the 150,000-mile extended federal class-action settlement threshold. Despite this clear history, the franchise dealership is actively refusing to open a factory Techline case or submit a Prior Work Authorization (PWA) to repair this safety defect, citing the vehicle's current odometer reading (152,142 miles). Kia Corporate has failed to override the dealer franchise or provide alternative transportation. The manufacturer is actively leaving an inherently dangerous, unserviceable vehicle on the road by refusing to honor a pre-existing condition documented within warranty limits. A formal dispute has been initiated with the BBB AUTO LINE (Case #[XXX]). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On [XXX], my 2020 Kia Soul (2.0L Nu MPI, VIN [XXX], approximately 102,420 miles) suffered total engine failure: complete loss of motive power, stalled and would not restart. This is the exact defect covered by federal recall 21V259000 / Kia SC209 (piston oil rings causing engine damage and stalling). The SC209 recall remedy had already been performed on this vehicle at Kia of Daphne (Daphne, AL) in June 2026. The recall did not prevent the failure. Symptom history matches the defect: the vehicle has burned oil excessively its entire life (oil changed every 3,000 miles; oil like sludge by approximately 2,000 miles) - the textbook piston-ring symptom. Sputtering began June 2026; a spark-plug replacement bought two to three months before total failure. Diagnostic codes at failure: P0304 (cylinder 4 misfire), P219F (cylinder imbalance), P0014 and P0017 (camshaft/crankshaft timing correlation), P1327 (knock sensor) - internal engine and timing damage consistent with the recalled defect. On [XXX], Kia of Daphne inspected the vehicle ([XXX]). The technician found low compression and wrote the failure 'does not have to do with recall campaign sc209A' and is 'not covered under Kia warranty or recall,' quoting $5,855.28 for an engine long block. I dispute this: low compression plus lifelong excessive oil consumption is the classic signature of worn piston oil rings - the exact SC209 defect. The one-sentence dismissal does not address the documented symptom history. Kia corporate cases [XXX] (opened 09/30/2026) and [XXX]; rebuttal submitted 10/07/2026 requesting field-engineer review; no response as of 10/15/2026, cases now closed. Safety: total loss of motive power AFTER the remedy was performed. This post-remedy SC209 failure belongs in the federal safety agency's investigation of Kia recall remedy effectiveness.

While driving my 2013 Kia Soul 1.6L GDI on the highway, the vehicle suddenly lost significant engine power and the Check Engine Light began flashing. The sudden loss of power at highway speed created a safety concern because I could no longer maintain normal highway speed with surrounding traffic. I exited the highway and drove home at reduced speed while the Check Engine Light continued flashing. Christian Brothers Automotive inspected the vehicle. Their diagnostic scan identified a pending P1326 code. The technician rechecked the knock sensor that had previously been replaced in July 2026 and confirmed that the sensor was functioning properly. After the engine reached operating temperature, the technician heard an abnormal internal engine knocking noise. Further testing determined that the noise was originating inside the engine, and Christian Brothers concluded that the engine requires replacement. The vehicle was subsequently taken to an authorized Kia dealership in Rosenberg, Texas and has been available for inspection. Kia declined engine replacement because the vehicle exceeds the mileage limit of its extended engine warranty. Kia also denied my request for goodwill assistance. Prior to this failure, the vehicle had experienced a knock-sensor-related issue that was repaired in July 2026. At the time of the highway incident, the significant symptoms were sudden loss of power and a continuously flashing Check Engine Light. I am concerned that the P1326 code, internal engine knock, flashing Check Engine Light and sudden loss of power may be associated with a connecting-rod-bearing/KSDS-related engine failure. I am reporting this because the sudden loss of engine power occurred while traveling at highway speed and could have resulted in a collision.

The contact owns a 2015 Kia Soul. The contact received notification of the federal safety agency Campaign Number: 20V750000 (Engine). The vehicle was taken to the dealer, and the engine was inspected and it was determined that there was no failure with the vehicle. The contact was charged for the diagnostic test. While driving at an undisclosed speed, the vehicle went into LIMP Mode and failed to accelerate above 20 MPH. The check engine warning light was illuminated. The vehicle was taken back to the dealer a second time, but no failure was found. The vehicle was then taken to Pep Boys, who diagnosed that the engine was leaking oil onto the exhaust system and catalytic converter. The vehicle was taken back to the dealer a third time, where it was determined that the catalytic converter was clogged and the diagnostic trouble codes were cleared. The dealer informed the contact that the recall repair would not be performed until the rod bearings had failed. The vehicle later caught on fire near the catalytic converter and the contact extinguished the fire. The manufacturer was notified of the failure by phone and a case was filed. The failure mileage was approximately 145,000.

The vehicle experienced complete and sudden engine failure while actively driving on a roadway. The engine began making loud, violent knocking noises, the check engine light illuminated, and the vehicle completely stopped and lost all motive power mid-drive. I believe this is directly caused by the defective piston oil rings covered under the federal safety agency Safety Recall Campaign 21V‑259 (Kia Campaign SC209). The vehicle had only just begun exhibiting these severe symptoms on the exact day it stopped working. The loud engine knocking, immediate check engine light, and rapid internal oil loss all occurred rapidly within hours of each other on the same day, leading directly to the total mechanical failure and seizure. The engine component is currently intact and remains completely available for physical inspection upon request. The engine in my Kia Soul is the 2.0L Nu MPI. The vehicle was towed to an authorized Kia dealership service center. The dealership confirmed that the engine has completely failed and had loud knocking sounds, but they are attributing the issue to an external leak in an attempt to deny coverage under Safety Recall SC209. The manufacturer (via the dealership, Techline, and Kia Corporate) has inspected the vehicle, but they have refused to perform the required internal engine teardown to inspect the piston rings or to honor the federally mandated recall remedy and fix my engine for free despite the recall. I have been fighting this for over two weeks now. I also provided my regular oil change documentation to show there was zero owner neglect.

consumer protection complaint against Gateway Kia of North Brunswick for wrongful warranty denial, deceptive business practices, and failure to comply with a federally mandated class action settlement.On Friday, September 25, 2026, my 2021 Kia Soul was left at Gateway Kia due to engine distress. The service department performed a physical mechanical bearing test and confirmed that the vehicle has a failed connecting rod bearing (the engine rod is shot).Despite this definitive physical proof of mechanical failure, the dealership's service department and Kia Corporate Consumer Affairs flatly refused to honor the repair or provide a mandated loaner vehicle. They claimed the vehicle is "out of warranty" and "does not match a recall."This vehicle is explicitly covered under the Kia Nu Engine Class Action Settlement, which legally mandates a Lifetime Warranty Extension for connecting rod bearing wear and failures for qualifying vehicles, regardless of original ownership or standard factory warranty expiration. Furthermore, the settlement explicitly dictates that a free loaner or alternative transportation must be provided while a class vehicle is held for a qualifying engine failure.By running a physical test that proved a settlement-covered mechanical failure, yet refusing to honor the court-ordered warranty extension, Gateway Kia is engaging in deceptive trade practices and violating federal class settlement terms. They are holding my inoperable vehicle while I am forced to maintain a $449.13 monthly finance payment to Credit Acceptance Corporation for a vehicle they refuse to fix.Requested Resolution:I request that the Division of Consumer Affairs investigate Gateway Kia of North Brunswick and compel Kia America, Inc. to immediately authorize the engine replacement under the Class Action Settlement terms.

My 2016 Kia Soul 1.6L GDI has an unresolved engine-related safety and recall concern. The vehicle is associated with safety recall SC176 / the federal safety agency 19V120, which remains identified as incomplete in the vehicle’s recall records. Kia also sent a recall renotification stating that the recall had not been completed. The vehicle was taken to an authorized Kia dealership after experiencing engine knocking, difficulty accelerating, and a no-start condition. Repair Order #544458 documents the reported engine knocking, trouble accelerating, and inability to start. The repair order also states that the vehicle was towed out because Kia Techline declined the engine request due to related recall work not having been performed. The vehicle was released without the requested engine replacement or a completed resolution. The concern is that the vehicle experienced serious engine-related symptoms while an applicable safety recall was listed as incomplete, and the manufacturer’s authorization process did not result in a completed recall-related remedy. The vehicle was subsequently removed from the dealership. I request that the federal safety agency document and review this complaint, including whether the recall remedy and engine-related concerns are being appropriately addressed. The vehicle and supporting records may be available for inspection upon request. Supporting documentation includes the Kia recall letter, recall verification, dealership repair order, and communications concerning the manufacturer’s review.
