The contact owns a 2016 Kia Sorento. The contact stated that while driving at 50 MPH and depressing the accelerator pedal, the vehicle speed decreased. The contact was able to pull into a parking lot safely. The contact attempted to restart the vehicle, but the vehicle failed to restart as intended. An independent mechanic and a dealer were contacted. The vehicle was towed to the dealer, where it was diagnosed that the engine starter needed to be replaced. The vehicle was then towed to an independent mechanic, where it was diagnosed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 83,000.

The vehicle is a 2016 Kia Sorento equipped with a 2.0L Turbo Theta II engine subject to the KSDS (Knock Sensor Detection System) safety recall. The original engine was replaced at approximately 70,000 miles under Kia’s engine service program. The replacement engine currently has approximately 32,000 miles. The vehicle developed internal engine damage diagnosed by a Kia dealership as a burnt exhaust valve. A burnt exhaust valve indicates abnormal combustion conditions such as lean operation, pre-ignition, detonation, timing deviation, injector malfunction, or lubrication failure. These are conditions the KSDS recall was intended to detect and mitigate. Kia Consumer Affairs denied warranty coverage, stating that the extended warranty applies only to rod bearing failure and that no further escalation would be pursued. Kia Consumer Affairs declined to escalate the matter for District Parts & Service Manager review and directed the owner back to the dealership. During the prior engine replacement, the dipstick was observed to be glued in place, raising concerns regarding oil level accuracy and lubrication integrity on the replacement engine. This complaint is submitted due to concern that a KSDS safety recall-related engine failure involving abnormal combustion was not properly reviewed or escalated, and that recall procedures were not administered in accordance with their intent.

Paint is bubbling and peeling off. Been to the dealership and they don’t seem to want to help. I have an extended warranty on the paint until 12/29/2025. They’re giving me the runaround.

Engine suddenly started making a lot of clattering noise. Oil consumption has been extremely high! Mechanic stated engine needs replaced.

For about 23,000 miles our mechanic has mentioned that the engine is burning oil. The exhaust pipe is covered in black soot. I monitor the oil level and it is always low even after oil changes with no oil leak. This has been provided to Kia with no remedy. Recently our Sorento was in a busy highway and the check engine, oil and battery lights came on and the car went into limp mode. We had the vehicle towed to Kia Chula Vista and the engine will be replaced by them. My concern is that the catalytic converter will soon fail and the engine issues need to be addressed for all of these makes/models before someone gets seriously hurt or killed.

The safety hazard began with a pattern of ignored warnings by the authorized dealer network. On Aug 15, 2025, I brought the vehicle to Luther Kia of Bloomington for a Check Engine Light. The dealer simply cleared the code without diagnosis, failing to catch early signs of engine trouble. On Sept 22, 2025, the engine failed again. I drove the vehicle in unsafe "limp mode" to Luther Nissan Kia [XXX] ). They found the engine was "4 quarts low on oil" (severe starvation just 37 days after a dealer oil change). Despite this catastrophic finding, they failed to diagnose the root cause and released the unsafe vehicle to me after selling only a spark plug replacement. On Sept 26, when I attempted to pick up the vehicle, the Check Engine Light was flashing immediately at handover. I refused to take the unsafe vehicle. The dealer then replaced an Oil Control Valve (OCV) and released the vehicle to me again later that day. After this second "repair," I drove the vehicle for only a few miles before the engine failed again with a Check Engine Light. The dealer has since admitted in writing (BBB complaint #XXX) that the engine was "deprived of lubrication" due to the initial low oil condition. By ignoring early warnings and releasing a vehicle with a dying engine twice, the dealer put me and other motorists at risk of a sudden loss of power at highway speeds.

Vehicle: 2016 Kia Sorento, VIN [XXX] Incident Date: November 13, 2025 Incident Location: Durham, NC (3828 Guess Rd) Cause of Loss: Engine Fire, confirmed by Durham Fire Department Report (Incident #253663) as "originated from under the hood." TECHNICAL NARRATIVE & SYMPTOMS (CRITICAL FOR LIABILITY): I am filing this complaint to report a catastrophic vehicle fire that I believe is directly linked to multiple acknowledged manufacturing defects that create a fire risk in Kia vehicles. ABS/Traction Control Light Warning (Direct Fire Risk Symptom): Immediately prior to the loss, the ABS and Traction Control warning lights were constantly illuminated. This is a known precursor symptom for the defective Hydraulic Electronic Control Unit (HECU) or ABS Module short-circuit, which has been cited in numerous Kia fire recalls (e.g., NHTSA 20V019, 20V519). The fire's origin under the hood is consistent with this component failure. Prior Engine Failures (Systemic Defect History): This vehicle has a history of catastrophic manufacturing defects: The engine assembly was replaced in 2023 due to the known Theta II Rod Bearing Failure. The knock sensor was replaced in September 2025 as part of the KSDS Product Improvement Campaign, demonstrating the vehicle was still under active service for critical engine monitoring defects just weeks before the fire. Potential Tow Hitch Wiring Fire Risk: The vehicle was fully engulfed, but the fire may also be linked to the defect cited in NHTSA Recall 22V703 (tow hitch wiring harness short circuit, which also poses a fire risk). I require a full investigation into this defect leading to compensation for the total loss of the vehicle and consequential damages.

The top padded dash of the instrument panel and the lower crash panel of the instrument panel, which the mechanic identified, have been developing cracks since the car was three years old. I made 3 calls to corporate customer service after the dealership said that the warranty had expired. I was told by the manufacturer that as long as I did not get hurt or cause an accident that they could not do anything about replacing the parts. Since then, numerous additional cracks have developed in the padding, showing deep cracks through the padding to the surface below. The airbags are in the area of the damage. I tried many times to submit photos and a statement from the mechanic who was assigned to my car at the dealership, but each time it failed to load the 8 pictures on this form. If you would like, I could mail them to you if you give me the mailing information. I feel that in time, the pieces will become loose while driving the car and cause a distraction, or the airbags could fail.

The car was running as normal and then randomly it started kind of rough and seemed like maybe just cold. But I had my mechanic take a look, and he said that when he started it, which was the next day that it made a loud knocking sound upon start. On the 30th I had it towed out to West Hills Kia in Bremerton. And they reported back that the engine needed full repair. I only owned this car one year and before me it was reportedly well maintained. I maintained it well also! Kia is denying all recall, but it’s a 2016 Kia sorento. It’s within the one or two years that the recall doesn’t cover??? The brake lights also work and always one of them is not working. It is not exclusively one or the other but the bulbs keep burning out. I need to know what to do to get this engine fixed, and it should fall under the bad engines that Kia’s have!
