2015 Kia Sorento Complaints

ELECTRICAL SYSTEM,VEHICLE SPEED CONTROL,SERVICE BRAKES — Filed 07/08/2026

I parked my car and it was sitting for about an hour I came back to the car and heard a humming noise found that weird but I had to drive home about 10 mins later I parked car, sound was still going even while car was off. So I thought to let it sit for another while. Came back to car sound was still on I started car and the abs, traction, & brake light came on and not even 2 mins later my car starts smoking. So immediately I shut it off and have to leave my car parked in another city because I didn’t want to risk driving it home. Fast forward to next day. I got to my car and notice the speedometer had went out. i called Kia because I read about the HECU ABS recall. the service rep assured me my car would be covered so I pay a tow to get it towed to Kia dealer where they then tell me the recall had been repaired in a year that I didn’t even own the car and they refuse to look at it or fix without a fee. With this problem being a fire hazard and a manufacturing problem I should not have to come out of pocket for Kia mistake. I will be escalating this to corporate level.

My 2015 Kia Sorento is experiencing a catastrophic structural failure of the exhaust system where the front manifold catalytic converter has internally collapsed This is a severe safety hazard because the physical blockage of the exhaust flow creates massive engine backpressure stalling when trying to drive even a small hill on highway, risking sudden engine stalling, unprompted deceleration, and power loss at highway speeds, which increases the risk of a crash. Furthermore, the blocked exhaust gases generate extreme temperatures under the hoods if it's running hot presenting a distinct vehicle fire hazard. I have maintained this vehicle and had all previous safety campaigns addressed, including a complete engine replacement and the required engine control software updates. Despite these recalls being fully completed, the vehicle has still suffered this severe exhaust system failure. The Check Engine light was on, and diagnostic scanning shows fault code P2096.I thought it was my transmission but a professional dealer assessment confirmed a manifold catalytic converter," "contamination of honeycomb on front of rear catalytic converter," and severe "contamination on the O2 sensor."He could not fixed An oxygen sensor replaced had to be fixed by someone else Abrasive ceramic dust from the melting manifold structure is actively being drawn back into the engine cylinders, threatening to destroy the newly replaced engine that Kia replaced but . this failure mirrors the exact physical mechanics and safety risks outlined in Kia's previous safety campaign SC176 (NHTSA Campaign 19V-120). Despite experiencing the identical defect and safety threat on a fully updated vehicle, my VIN was excluded from the recall I am filing this complaint because this known safety defect poses an active threat to my safety.my husband was a 100% disable vet who passed in April 2025,I can'a afford to have this same item repaired that Kia suppose to have repaired,Please help me

My 2015 Kia Sorento is experiencing a catastrophic structural failure of the exhaust system where the front manifold catalytic converter has internally collapsed and broken apart. This is a severe safety hazard because the physical blockage of the exhaust flow creates massive engine backpressure, risking sudden engine stalling, unprompted deceleration, and power loss at highway speeds, which increases the risk of a crash. Furthermore, the blocked exhaust gases generate extreme temperatures under the hood, presenting a distinct vehicle fire hazard. I have proactively maintained this vehicle and had all previous safety campaigns addressed, including a complete engine replacement and the required engine control software updates. Despite these recalls being fully completed, the vehicle has still suffered this severe exhaust system failure. The Check Engine light was on, and diagnostic scanning shows fault code P2096. A professional dealer assessment confirmed a "collapsing manifold catalytic converter," "contamination of honeycomb on front of rear catalytic converter," and severe "contamination on the O2 sensor." An oxygen sensor replaced in December 2025 has already been destroyed by the upstream ceramic debris. Abrasive ceramic dust from the melting manifold structure is actively being drawn back into the engine cylinders, threatening to destroy the newly replaced engine. This failure mirrors the exact physical mechanics and safety risks outlined in Kia's previous safety campaign SC176 (NHTSA Campaign 19V-120). Despite experiencing the identical defect and safety threat on a fully updated vehicle, my VIN was excluded from that specific campaign, and Kia corporate has flatly denied goodwill assistance. I am filing this complaint because this known safety defect poses an active threat to vehicle control and occupant safety. I've attached the current repair assessment, and can provide the assessment of the previous replacement of the O2 sensor when warranted.

FUEL/PROPULSION SYSTEM — Filed 06/05/2026

I am filing a safety complaint regarding a Kia vehicle I purchased from CarMax Waldorf approximately 3 months ago. The vehicle has developed a strong gasoline/fuel odor that is consistent with a possible fuel leak. This creates a serious safety concern, including the risk of fire or explosion while driving or operating the vehicle. The issue began shortly after purchase and has continued. The vehicle is now unsafe to drive due to the strong fuel smell. When I contacted CarMax about the issue, I was instructed to take the vehicle to a Kia dealership instead of CarMax inspecting or addressing the safety concern themselves. I believe this is improper handling of a potentially dangerous defect in a recently sold vehicle. At this time: * Vehicle emits strong fuel/gas smell * Safety risk increases while driving * Vehicle has been in my possession for only 3 months * Issue appears to be early or pre-existing defect * I was redirected away from CarMax responsibility I am requesting that this safety issue be investigated as a potential fuel system defect and documented appropriately.

I am filing a safety complaint regarding a 2015 Kia Sorento equipped with the 2.4L Theta II engine. The vehicle developed progressive engine knock, reduced power, and check engine warnings while driving. Diagnostic trouble codes include P0017, P0014, and P0340 relating to crankshaft/camshaft timing correlation and camshaft position faults. A Kia dealership performed diagnostic testing using Kia diagnostic equipment (KDS) and documented abnormal knock activity across all cylinders. The dealer repair order specifically states: * “Found data PIDs for additional knock noise” * “All registering knock on all cylinders” * “Recommend replacement of engine sub assy based on knock detection” The vehicle experiences engine knocking and loss of power that create concern for sudden engine failure or stalling while driving, which could increase crash risk. This complaint is being submitted because the symptoms appear consistent with the known Theta II engine defect involving connecting rod bearing failure, engine knock, seizure, and potential engine failure.

I own a 2015 Kia Sorento with Snow White Pearl paint. The paint is prematurely peeling/delaminating from multiple areas of the vehicle despite normal maintenance and no accident damage. The vehicle was inspected by a Kia dealership, and I was informed that the condition appears to be a paint defect rather than normal wear and tear. The paint failure is occurring in a manner consistent with numerous complaints from other Kia owners involving Snow White Pearl paint adhesion failure. The peeling paint affects the appearance and value of the vehicle and continues to spread. In areas around the roofline/windshield pillars, exposed surfaces may also create long-term corrosion concerns and potential visibility/safety issues. Kia has acknowledged my complaint under Case #26008837 but has not agreed to repair the defect. I am submitting this complaint because this appears to be a widespread manufacturer paint defect affecting Kia vehicles with Snow White Pearl paint.
