Engine

67 reports1 crash5 fires
“I bought a used 2020 Kia Sorento LX 2.4L in 2022. It had 15,000 miles on it. AT 50,000 miles I noticed it was consuming oil. I have been changing the oil at 5,000 mile intervals even though the manual calls out to do it every 7,500 miles. I have records of the maintenance for every oil change done on this vehicle. I kept a log and now at 54,740 miles it is consuming 1 quart every 500 miles or so. I took it to the dealer on 10/19/2026 and was told that since I was not the original owner there was no warranty coverage on it. So that nullified the 10 year/100,000 mile warranty. I was told they could do a chamber cleaning for $800.00 and if that failed I would need to replace the engine at an out of pocket cost to me of $9,000.00 to $10,000.00 I have to monitor the oil level constantly to avoid the engine seizing and breaking down in traffic . This auto is used by my spouse to drive my grand kids to and from school. There are no warnings or messages on the oil level so it is driven with uncertainty .”

Electrical system

20 reports7 fires
“Driving at highway speed, the vehicle began to make a loud rattling noise that came from under the vehicle. A passerby pulled even with my car and began frantically gesturing. After a few seconds of confusion, me daughter said the she thought the man was saying "it's on fire." We pulled over to the shoulder of the road, exited quickly and realized there was fire visible in the engine area, seen through the grill. A good samaritan attempted to suppress the fire with an exstinguisher but moments later, it was fully engulfed.”

Fuel/propulsion system

10 reports1 crash2 fires
“The vehicle suffered a sudden, severe engine malfunction/misfire while in operation, presenting a serious safety hazard on the road. Following the incident, the vehicle was taken to an authorized dealership service center (Repair Order #XXX), where technicians verbally confirmed that the engine requires a complete replacement due to internal mechanical failure. The catastrophic mechanical failure of the engine directly caused consequential damage to the emissions system, entirely clogging the catalytic converter with unburned fuel/debris. Despite the clear link to the known, systemic defects inherent to the Theta II engine line—which is subject to active federal consent orders, safety recalls, and lifetime warranty extensions—both the dealership and Kia Corporate are refusing to honor the 8-year/80,000-mile Federal Emissions Defect Warranty. The manufacturer is attempting to use the catastrophic failure of their own defective, recalled engine line to evade their legal environmental and safety warranty obligations, leaving the consumer stranded without alternative transportation. This represents a systemic effort by the manufacturer to deflect liability for…”

“**Suspected Sudden Unintended Acceleration – 2020 Kia Sorento EX V6** On October 24, 2026, the driver of a 2020 Kia Sorento EX V6 experienced two episodes of suspected sudden unintended acceleration. The vehicle reportedly accelerated unexpectedly while in Reverse (R), causing it to collide with an apartment building. Following the initial collision, the driver shifted the transmission into Drive (D), at which point the vehicle reportedly accelerated forward unexpectedly. According to the driver, both incidents occurred so quickly that she was unable to apply the brakes. The collision caused significant damage to the apartment building, including structural damage requiring reinforcement, and damaged two other vehicles. The airbags did not deploy. No injuries to the driver have been reported. The driver also recalls receiving a previous recall notice for a vehicle component that was not repaired. The specific recall has not yet been identified. The vehicle has been towed and is being preserved for a potential independent investigation, including examination of the Event Data Recorder (EDR). We request that NHTSA review this incident as a possible vehicle safety…”
