2020 Kia Sorento

The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing.  There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

**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.

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 .

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.

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.

While driving my 2020 Kia Sorento on the freeway at highway speed, the panoramic sunroof suddenly shattered without warning. There was a very loud explosive sound that startled and frightened me while I was driving. I was not aware of anything striking the sunroof immediately before it shattered, and there were no warning lights, messages, noises, cracks, or other indications that the glass was about to fail. Because I was traveling at freeway speed when this occurred, the sudden explosion/shattering of the glass was extremely distracting and created a serious safety concern. I was frightened by the unexpected loud noise and could have lost control of the vehicle. Broken glass from a panoramic sunroof also presents a risk to the occupants of the vehicle and to other motorists. The component that failed was the panoramic sunroof glass. To my knowledge, the failure has not yet been reproduced or confirmed by a Kia dealer or independent repair facility, and the vehicle has not yet been inspected by Kia for the cause of the failure. I am reporting this incident because the sunroof appeared to shatter suddenly during normal highway driving without any prior warning, and I am concerned that this may represent a safety defect.
