2020 Kia Sorento Problems

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 .

The contact owns a 2020 Kia Sorento. The contact stated that while driving, there was an abnormal banging sound coming from under the hood of the vehicle and the vehicle shuddered abnormally. The contact stated that the Forward Collision Avoidance warning light was temporarily illuminated. The vehicle was taken to a local dealer where it was diagnosed; however, the cause of the failure was not yet determined. The manufacturer was made aware of the failure. The failure mileage was approximately 34,000.

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.

Driving on highway at 65, traction control light, airbag light, parking light, bcw warning, all came in at the same time. I was able to pull off to the side and re start engine to clear the lights. As soon as I got up to 40 lights one by one flickered on until up to highway speed and then all flickered and dash dings. Two independent shops ran diagnostics and noted that only battery was dead. Replaced battery and the lights came back immediately.

The contact called on behalf of his daughter who owns 2020 Kia Sorento. The contact stated that the vehicle was taken to a dealer for a routine oil change when the contact was informed that there was an unknown issue with the vehicle however, the vehicle was not diagnosed or repaired. The vehicle was taken to a different dealer where it was diagnosed that the transmission fluid was leaking and the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

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 documented powertrain safety failures onto individual consumers.

The vehicle was not even 3.5 years old, it had been serviced in February 2023 and there was no warning before the fire began. The vehicle stopped accelerating and I immediately pulled over. The fire began as soon as I stopped the car and the vehicle was engulfed within minutes. My daughter and I were in the car. We barely escaped before the vehicle was on fire. I did not have a vehicle hitch on the vehicle and this was unrelated to the vehicle recall notice that I received several weeks after my incident.

**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 defect. The cause of the unexpected acceleration has not yet been determined.

This incident occurred on 10/03/26 at approx. 11:45 AM. Location: Squankum-Yellowbrook Rd. (524A) Howell NJ. Temp: 73 F. Road condition: 2 lane rural clear and dry. Description of incident: While driving @ approx. 40 MPH with no on-coming or traffic ahead or behind, the entire right rear passenger window spontaneously imploded, explosively showering the entire rear seat with glass shards. Upon immediately pulling off the road and upon my own examination (and shortly thereafter by responding police) no impact object that could have caused the glass breakage was found. Had there been rear seat passenger(s) at that time undoubtedly that person(s) would have sustained head/face or eye injuries.

This morning, I had the software upgrade patch applied to my 2020 Kia Sorento that was supposed to fix the potential theft issue. After that service appointment, I started a 2 hour road trip. We stopped for gas and when we went into the store, I noticed that my car was not sounding the horn when I hit the key FOB twice like normal. I went back to the car and saw that the car was in fact not locked. I was able to lock the car manually, but had I not paid attention, someone could have snuck into my unlocked car. Later in the roadtrip, I needed to clean my windshield using wiperfluid and wipers. I sprayed the wiper fluid, but to my surprise the windshield wipers did not activate. I tried all the settings on the stick to activate the wipers, but they did not activate. I was driving 70mph on a highway and could not see. This was a huge safety problem. Luckily this was momentary as the speed cleared the wiper fluid. But had it been raining, I would not have been able to see which is unsafe for me, my passengers and those around me. Third, I noticed that my headlights were not working as expected. The Auto setting did not seem to be activating as normal. After playing with it, it appears that the Auto and Off settings on the lights seem to be switched. This is unsafe because drivers rely on that Auto setting to turn the lights on when it is necessary. They may think the lights are on when they are not and are not able to be seen by other drivers. By the time I realized these things, the service department at the dealership was already closed. I have tried to leave them a voicemail, but their phone is not set up to accept that. I have sent an email and will be calling them as soon as they reopen on Monday. There are no warning messages to tell the drive about these issues.

The dealer was made aware of the failure; however, the contact was required to pay a fee for a diagnostic test. The manufacturer was not made aware of the failure. The failure mileage was unknown.

I REALLY DONT REMEMBER THE DRIVER IMPACTED THE FRONT DOOR AREA OF MY VEHICLE.

While driving my 2020 Kia Sorrento at low speeds, my brakes will lock up on me, and it sounds like metal to metal. Rubbing, I was almost rear, ended because of it. It feels like a very hard grab. This is happened quite a few times and I am a commuter so it’s very scary not knowing when this is going to happen.

Driver seatbelts randomly unlatches itself while operating vehicle.

I was driving on the highway at 65 mph with other flow of triffid. As I was crested a hill, I had notice ahead there was emergency vehicles ahead about half-three quarter mile and I had let go of the accelerator. By the time I had looked down in front of me there was a vehicle that appeared to not have stopped due to not seeing any brake lights. By the time I realized the vehicle had stopped, I rear ended him. During the collision the was six people in the vehicle including myself. Me, my wife and four of our children. Ages 13, 11, 7 & 2. The 2 yr old was in a car seat. Out of the the 6 seatbelts that were buckled were dislodged from it receptacle. The 11 yr old daughter was flung to the front of the vehicle hitting her head into the dashboard causing a concussion and neck pain. The front facing car seat had its buckle dislodged but the 2yr old did not sustain any injuries. Both of them sitting in the 2nd row. The 13 yr old in the 3rd row, his seatbelt was dislodged and sustain bruising and scrapes on his right side of his face. The 7 yr old complained about his stomach, but his seat belt did not dislodge. And my wife had sustained bruising around her waist and a broken collarbone. Theses seatbelts should not have dislodged from its receptacles if the were clicked in. I always make sure that everyone has there seatbelts on before operating the vehicle.

We bought a brand new 2020 Kia Sorento on [XXX]. A little after a year we started to notice noises from the wheel hubs. Kia has replaced the tires thinking that was the problem, but it failed to be fixed. We have replaced Rotors, wheels, hubs and bearings but the problem persists. The last facility that replaced all 4-wheel hub bearings assembly said that since we have brought the vehicle to 4 different locations and the problem persist that we should write a complaint to nhtsa.gov. We feel unsafe to drive the kia due to the noise which is very loud. There are no warning lights on in the vehicle. The car is available for inspection upon request. We don't know what else to do or where to go from here since not even the Kia dealer has been able to correct the problem.

While driving on freeway, approximately 70mph, on my way to work, I all of a sudden without warning was unable to control my vehicle with the steering wheel. Somehow I seemed to have lost control of the steering wheel and the vehicle spun around. I could have collided with another vehicle or could have been hit by oncoming traffic, but thankfully I was not near to any other vehicles at the time of incident. I was unable to drive it afterwards as the entire back left wheel was completely detached. I had to get the vehicle towed back to my house then eventually to Kia. Kia will not admit faulty equipment although that is the only explanation of the incident that happened on the freeway. The entire left rear suspension system has to be repaired. ALthought there are no signs of a collision with the vehicle, Kia and the extended warranty company is attempting to place blame on me being in a collision, which is 100% inaccurate.
