Recently, while driving on a busy multi-lane highway my 2016 Kia Sorento suddenly lost power, started shaking and slowed down causing traffic safety hazard. The engine stalled after slowing down. The car needed to be towed at my expense.my check engine light came on for my KSDS, the engine went limp mode and unable to accelerate over 50 miles and hour on the highway. My engine is blown. gasoline smell fumes came through vent causing me to have an attack car started to catch fire.
The engine was going through over 5 quarts of oil about once a month. There were no visible leaks. For months, there was no check engine light illuminated so the dealership couldn't help determine and fix the problem without charging over $10,000 to open the engine, which I couldn't afford. A Service Advisor, in their words, told me to, "Run it until it dies," so that they can start using the warranty. This to me was very unsafe, especially for my infant who was there when she said this. Months later, the car started shaking intensely and the check engine light finally came on. The car stopped working in the middle of the freeway but I was able to exit and take it to the nearest dealership. They were able to run a diagnosis and said it was an engine misfire and they replaced it (I was able to use my warranty for some of the repairs but still had to pay about $4000). …

Vehicle: 2016 Kia Sorento, VIN [redacted] 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 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 [redacted] ). 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 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 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. …
