KIA Complaints

Update – April 1, 2026 (NHTSA Complaint #XXX) Today, April 1, 2026, at XXX I was informed that the engine replacement will not proceed because “the 3 years or 36,000 miles have passed.” This is incorrect. My Kia Soul 2022, VIN [XXX] , currently has 44,649 miles and was purchased in 2021. Kia’s Powertrain warranty is 10 years / 100,000 miles for the original owner and covers the engine. The basic 5-year/60,000-mile warranty does not apply in this case. On February 2, 2026, the technician documented stuck oil control rings allowing oil to enter the compression area, causing excessive oil consumption. A PWA was requested for full engine replacement. I have three failed oil consumption tests (more than 1 quart per 1,000 miles) and low compression on piston 3 (145 PSI). This would be the second major engine intervention in less than one year. The dealer is proposing only a partial repair of pieces, which does not solve the root cause and represents a safety risk (engine damage, possible fire, or loss of power), as warned in the official Kia letter I received. I request that NHTSA review this unjustified denial of warranty repair and require Kia to honor the Powertrain coverage. Attached: Technician notes from February 2, 2026, the three oil consumption tests, official Kia Puerto Rico letter, full repair history, and denial communication from April 1, 2026. Thank you.

STATEMENT OF FACTS: I presented my Kia K5 for two safety recalls (SC356 and SC263) with an active Check Engine Light for code P047100 (Exhaust Pressure Sensor). I informed the service advisor, Aliyah, that this code is a symptomatic secondary fault of the pressure irregularities addressed in Recall SC356, which explicitly lists an "Illuminated Check Engine Light" (MIL) as a primary warning sign. The dealership dismissed my technical assessment—which was backed by advanced AI data analysis. After the software update was performed, the advisor claimed the code remained "active," thereby "proving" it was unrelated to the recall. Based on this, I was charged a $248 diagnostic fee and told I needed a $534.02 out-of-pocket hardware repair for a "physically failing" differential pressure sensor that was allegedly reading 2 HPA against a spec of 23.09 HPA. EVIDENCE OF ERROR: Upon taking delivery of the vehicle, the Check Engine Light was completely extinguished. If the light were truly "still active" after the update, as I was told to justify the fee, the fault would have been present at pickup. Since then, I have driven over 120 miles (including multiple cold-start drive cycles between [XXX] and my place of work) with a 100% clear dashboard. My XXX App confirms the XXX fault is resolved, while the recalls remain "Open" administratively. REGULATORY VIOLATION: Under 49 U.S.C. Chapter 301, a manufacturer must remedy a safety defect without charge. A software "Logic Update" cannot physically repair a broken pressure sensor. The fact that the fault disappeared immediately following the update proves the sensor was functional and the fault was caused by the recall defect. By misdiagnosing a recall symptom as a non-covered hardware failure, the dealer effectively charged me for a federal safety repair. I request an investigation into these "diagnostic gatekeeping" practices and a full refund of the $248.00 fee.

The contact owns a 2022 Kia EV6. The contact received notification of NHTSA Campaign Number: 24V867000 (Electrical System) and the vehicle was repaired at the local dealer. The contact stated that four months later while driving 75 MPH, there was a popping sound coming from the rear of the vehicle. The message to "Check Electrical System" was displayed, and the vehicle unexpectedly decelerated to approximately 45 MPH. The contact continued driving and the message to "Stop Vehicle and Check Power Supply" was displayed. The vehicle decelerated to 5 MPH and failed to accelerate as intended. The vehicle was pulled over to the side of the road and inspected. All the doors were unlocked, and the vehicle then stalled. The vehicle failed to restart. The vehicle was towed to a dealer where it was diagnosed and determined that the Integrated Charging Control Unit (ICCU) assembly and fuse needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 148,309.

I kept all of the maintenance records for the oil changes. The engine blew a piston and I will need a new engine. Driving down the road, it just lost power and died. Local mechanic looked at it and said I needed a new engine. When I began looking for a new engine, the cost would have been $3500.00 plus labor. When looking for a used engine, the salvage person said there was a recall on the engines. I took it to the local dealer, said I was over the mileage. and would probably cost the dealer $9000.00. The car is almost 10 years old. It was a good car. It was a standard, which should mad it last longer.

The contact owns a 2020 Kia Telluride. The contact stated that while driving at various speeds, the high beam headlights failed to illuminate as intended, and the vehicle shuddered before losing automotive power. No warning light was illuminated. In addition, the contact stated that the warning lights failed to illuminate as designed when the engine oil level was low. The vehicle was taken to a local Auto Zone, where the relay and high beam headlights were replaced; however, the failure reoccurred. An appointment with the dealer was scheduled to inspect the vehicle. The vehicle was not yet repaired. Upon further investigation, the contact associated the failure with NHTSA Campaign: 24V148000 (Exterior Lighting); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was unavailable.

My engine has failed. This is the second car I’ve had from Kia that the rod barring has failed.

Urgent Escalation – Case CAS-XXX – Kia Soul 2022 VIN [XXX] – Excessive Oil Consumption Confirmed in 3 Tests – Partial Repair Unacceptable After Multiple Failures and Second Engine Intervention in Less Than six months INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2015 Kia Soul. The contact stated that the vehicle was repaired under NHTSA Campaign: 19V120000 (Engine, Engine and Engine Cooling); however, the repair failed to prevent the failure. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power while the accelerator pedal was depressed. The vehicle was taken to an independent mechanic, where it was diagnosed with a misfire in cylinders #1 through #4; the ignition coils were replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken to the local dealer, and the dealer determined that the failure was caused by a lack of vehicle maintenance. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 99,912.

Sliding Door Sensor Failed My daughter was getting in the van, when her brother hit the door button, if my husband wouldn’t have glanced over at that exact moment and pulled her back, this would’ve been another story. THE SENSOR IS NOT SENSITIVE ENOUGH! We as mothers are demanding sensors sensitive enough to detect smaller, fragile children!

The contact owns a 2019 Kia Sorento. The contact stated that while driving at an undisclosed speed, there was smoke coming from the vents, with the low oil warning light illuminated. The contact stated that several oil changes were needed. While inspecting the vehicle, the contact became aware that the oil levels were constantly low. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure, and the contact was advised to go back to the dealer for a diagnostic test. The approximate failure mileage was 146,060.
