2019 Kia Sorento

I am filing this complaint regarding my 2019 Kia Sorento and an engine failure related to Kia’s Product Improvement Campaign/KSDS (Knock Sensor Detection System) campaign. I purchased this vehicle used in 2022. Prior to the engine failure, I was never notified of any Product Improvement Campaign affecting my vehicle. Had I been notified, I would have immediately taken the vehicle to an authorized Kia dealership to have the campaign completed. My engine subsequently failed, and Kia denied coverage, stating that the Product Improvement Campaign was not completed before the engine failure occurred. Kia stated that notices were mailed to affected owners, but they have not provided me with documentation showing when my specific notice(s) were mailed, what address they were sent to, or proof that I was properly notified. I am concerned that affected owners may not be receiving adequate notification of this engine-related issue before a failure occurs. An engine failure can create a serious safety concern, especially if it occurs while driving, and owners may unknowingly continue operating vehicles affected by this condition without having the opportunity to complete the required update. I am requesting that NHTSA review this matter to determine whether Kia’s notification process for this campaign was effective and whether additional investigation is needed regarding engine failures associated with this issue. Vehicle Information: Year: 2019 Make: Kia Model: Sorento Date of engine failure: June 2026 I have documentation from Kia Customer Care regarding their denial of coverage and their statement that the campaign was not completed prior to engine failure.

The contact owns a 2019 Kia Sorento. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power and failed to properly accelerate. The vehicle was slowly driven to the residence and stalled in the driveway. After restarting the vehicle, the engine immediately shut off. There were no warning lights illuminated. The vehicle was later towed to the local mechanic, who confirmed that the engine had failed. The vehicle was later towed to the local dealer, who diagnosed that the engine had failed and needed to be replaced. The cause of the engine failure was unknown. The vehicle was not yet repaired. While purchasing the vehicle, the contact was advised to constantly monitor the engine oil due to a known oil consumption issue. The manufacturer was notified of the failure and informed the contact that the vehicle was included in the extended warranty program. The failure mileage was 125,202.

Engine, a Lambda 3.3 v6 started knocking periodically and consuming oil at about a half a quart a week. It is a know problem with this motor and well documented in its existence in all Hyundai and Kia vehicles using this engine. We now have been told that the head bolts are partially stripped. Another known problem and we are consuming coolant. This can is not trustworthy and could fail at any time. We are still paying off the loan if it matters.

The contact owns a 2019 Kia Sorento. The contact stated that while driving 64 MPH, the contact detected a shimmy and knocking coming from the front wheels. There was no warning light illuminated. The contact stated that the failure was a common failure with similar vehicles. The vehicle was taken to an independent mechanic, and an alignment, tire rotation, and wheel balance were performed. The vehicle was taken to the local dealer, where it was diagnosed and determined that the steering column needed to be replaced. The failure was associated with the flexible rubber coupler, PN: 56380C1500. The vehicle was not repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 122,222.

The paint is peeling in sheets, especially above the windshield, leaving the vehicle unprotected and vulnerable to rust. There were no chips or damage in this area prior to the paint beginning to peel away and once it started it's been progressing very quickly. Other owners have reported similar issues with this paint color (I believe it's pearl white) in Kia other forums online

My rear backup camera stopped working this year it's either a black screen or blinking screen no video will play. When I first started the video was foggy like moisture was in the camera and now it shows nothing. Other Kia sorento's my same model year have had a recall for the backup camera but mine is not on the recall list for some reason.
