Following an engine replacement performed at Billion Auto Kia in Rapid City, SD, I began experiencing persistent electrical system failures in my 2017 Kia Sorento. The vehicle alarm would activate randomly without cause, including while I was inside the vehicle with the engine running. Additionally, the door locks would engage spontaneously, trapping me inside the vehicle and preventing me from exiting. The only way to exit was to forcibly pull the door handle, which triggered the alarm. I have video documentation of these incidents. I presented the vehicle to Billion Auto Kia in Rapid City, SD — an authorized Kia dealership with these exact symptoms. The service department was unable to identify a root cause and provided no repair path, returning the vehicle to me unrepaired. 7 months later, Courtesy Kia of Brandon in Brandon, FL, another authorized Kia dealership diagnosed the root cause as a failed Body Control Module (BCM). During the service visit, a Kia dealership technician personally witnessed the alarm activating spontaneously while operating the vehicle, further confirming the defect. The BCM failure was present and active at the time of the prior authorized dealer visit and was not detected. The failed BCM has also caused the gear shifter to become completely stuck, unable to shift out of Park, leaving the vehicle fully inoperable. This vehicle has had 6 recall actions performed since purchase — 4 completed after my purchase in August 2023, and two completed prior to my purchase. Despite this recall history, the vehicle has experienced an engine failure and a BCM failure within less than 3 years of my ownership. Being trapped inside a vehicle with a malfunctioning lock system represents a serious safety hazard, particularly in the event of an accident or emergency requiring rapid exit. I am requesting the federal safety agency investigate whether a safety defect exists in the Body Control Module of 2017 Kia Sorento vehicles and whether additional recall action is warranted.

Vehicle has a recurring P0018 fault code (Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor A). Dealer diagnosed loose cam pins on Bank 2 requiring major engine repair. This fault creates a safety risk as improper camshaft timing can cause unexpected engine stalling while driving, resulting in sudden loss of power, power steering, and brake assist. The manufacturer has denied warranty coverage despite the vehicle being within the 10-year/100,000-mile powertrain warranty. This appears to be a known widespread issue on the 3.3L V6 engine. Vehicle has 96,000 miles and is still within warranty coverage period.

I found that he ignition key can be removed from my 2017 Kia Sorento while the transmission is not in the Park position. This is a shift interlock failure. Under FMVSS 114, the key must be trapped in the ignition unless the transmission is confirmed in Park. This defect caused the vehicle to roll down my driveway after my wife & daughter exited the car & were unloading groceries. The vehicle was purchased in April 2026 from a used car dealer lot. The defect was discovered shortly after purchase. No dealer repair has been performed yet. I am contacting Kia Consumer Affairs requesting a goodwill safety repair under FMVSS 114. Component affected: Power Train — Automatic Transmission — Shift Interlock System

I am reporting a serious defect involving my 2017 Kia Sorento 2.4 Liter GDI engine (VIN [XXX] ) At approximately 84000 miles, while still under the powertrain warranty, I brought the vehicle to the dealership from which I purchased it (Hutchinson Kia in Macon GA) due to engine hesitation and abnormal performance. I was initially told the engine might need replacement, but the dealer later claimed the issue was only a relay/software problem and performed a software update (likely the KSDS knock sensor update) At approximately 94000 miles, the engine suffered a SUDDEN CATASTROPHIC FAILURE while driving on the interstate, The failure was abrupt and created a dangerous situation in traffic. The Vehicle is now inoperable. The engine is equipped with the THETA II GDI engine, which has a documented history of bearing and connecting -rod failures, fires and sudden engine seizure. KIA is refusing to cover the failure, even though the symptoms began during warrantly and the KSDS update was reportedly completed. This appears to be consistent with the widespread THETA II engine safety defect previously investigated by the federal safety agency. The sudden failure of the engine posed a significant safety risk to myself, passengers and other motorists. I am requesting the federal safety agency review the incident and evaluate whether KIA is properly honoring required safety-related engine replacements for Thet II GDI equipped vehicles. Thank You.

The engine failed at a little over 73,000 miles. The vehicle was towed to the dealership where the warranty company refused to cover the engine. The engine had burned through the oil and that was why the engine failed. There was carbon build up inside the engine, causing it to fail. The oil had just been changed 1000 miles before it failed. There were no warning lamps before the engine failed. Once the engine failed, the check engine light appeared. The oil in the vehicle had been changed routinely and can be verified by the Carfax report. This could've caused a wreck. The manufacturer and warranty company are not taking responsibility for the engine failure.
