2017 Kia Sorento Complaints

ENGINE — Filed 02/16/2023

On February 16, 2023, the engine in our 2017 Kia Sorento SXL developed a sudden, loud knocking noise while driving. No dashboard warning lights illuminated at any time, including no oil pressure warning, check engine light, or other engine-related alerts. The vehicle remained fully operable and did not lose power or seize. I continued driving approximately 20 minutes home, including highway speeds up to ~75 mph. The following day, with the knocking noise worsening but still no warning indicators present, I drove approximately 25 minutes to an independent repair facility. The vehicle was then diagnosed with catastrophic engine failure attributed to oil starvation and was towed. Because the vehicle had fewer than 100,000 miles and was within the expected powertrain warranty period, we pursued a warranty review through Kia. Kia requested maintenance records, which we provided in full after gathering documentation from all service providers over a two-week period. Despite this, the warranty claim was denied, first citing gaps in initial records and later questioning oil type based on older receipts that did not explicitly state “synthetic oil.” At Kia’s recommendation, we authorized an oil pan inspection at our expense. Kia concluded that the oil filter appeared to be more than two years old, which conflicted with our documented maintenance history showing multiple oil changes during that period. Kia denied warranty coverage and quoted approximately $10,500 for engine replacement. We were advised that the replacement engine would be a remanufactured unit and that it was on backorder with no estimated delivery timeline. After approximately ten weeks without resolution, we located a compatible replacement engine at another Kia dealership and arranged transport of the vehicle there. The engine was replaced within three days for approximately $9,000. The repair included installation of a replacement engine, new spark plugs, and a passed state inspection.

On XXX, the oil warning light was illuminated in our 2017 Kia Sorento SXL and that the vehicle was leaking oil. We brought the vehicle to an independent repair facility (Tire Kingdom, Cairo, NY) for diagnosis on XXX. The repair facility provided an oral assessment with photographs indicating a suspected rear main seal leak. The engine was dry on the top but excessively wet between the engine and transmission, consistent with a significant oil leak in that area. We were advised that the vehicle could be driven in short intervals of approximately 25 minutes, provided that oil levels were closely monitored and topped off as needed. On XXX, we began driving the vehicle to transport our daughter to a train station 25 minutes away. Halfway through the trip, the vehicle began producing a metallic noise from the engine compartment. We immediately pulled over safely and turned off the engine. After stopping, we discussed next steps and then attempted to restart the vehicle. The engine started but immediately produced a severe mechanical rattling noise. It was shut off within approximately one second of startup. The vehicle was not driven further. The vehicle was then towed to Romeo Kia in [XXX]. Kia performed a diagnostic assessment and determined that the engine required complete replacement, with an estimated repair cost of approximately $10,000. This vehicle previously had a remanufactured engine installed in 2023 following a prior catastrophic engine failure. Between installations, the vehicle was maintained in normal service and was not overdue for scheduled oil changes at the time of this incident (27 days to go). At no point prior to the failure event was there clear indication of immediate catastrophic engine failure beyond the initial oil warning and leak condition. The failure progressed from a diagnosed external oil leak to immediate mechanical failure upon restart, requiring towing and full engine replacement.

To Whom It May Concern, I am writing to formally dispute a repair charge and report unacceptable service at Courtesy Kia (Mesa, AZ) regarding my vehicle. Timeline of Events: June 12, 2026: I brought my vehicle to Courtesy Kia for a mandatory software recall. Prior to this appointment, my fuel gauge worked perfectly. Immediately upon picking up the vehicle, the fuel gauge ceased to function. After calling customer service, I brought the vehicle back for inspection. The dealership kept my car for three days. Despite the issue being caused during their previous service, I was denied a loaner vehicle, forcing to come to take the car and use it during the weekend or I can wait until Monday 29 until the service manager back but I asked them I can’t use the car with this error as it’s not safe for me and my kids and that should be fixed by them since that’s their mistake and unfortunately I’ve had paid out-of-pocket for my family's transportation. June 26, 2026 (Diagnostic): The service department initially claimed the issue was a broken fuel pump and quoted me $1,210. I informed them this was impossible, as the fuel pump was completely replaced just 3 months ago. I requested to speak to the service manager, but was told he was unavailable until Monday. And the gentleman Michael who was taking care of my car said let me speak with the technician and back to me again with different quote The diagnosis was suddenly changed to a "fuel sending unit and gasket," with a new quote of $546?? But if I want I can wait until Monday to check with service manager. June 29, 2026: After receiving no follow-up call, I contacted the dealership myself. I spoke with Service Manager Shane Hackelton, who refused to take responsibility for the damage caused during the recall service and insisting that not related to recall software and should be fixed by myself. I look forward to your prompt response and a resolution to this matter.

POWER TRAIN,ELECTRICAL SYSTEM — Filed 06/16/2026

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 NHTSA investigate whether a safety defect exists in the Body Control Module of 2017 Kia Sorento vehicles and whether additional recall action is warranted.

While driving on the highway on Mother’s Day weekend with my wife and daughter, the vehicle suddenly lost acceleration and engine power while traveling on a 5-lane beltway. The vehicle would not accelerate and I was unable to maintain normal highway speed. I had to coast to the side of the road with the hazard lights activated because of the safety risk. The vehicle was eventually restarted after being towed to a dealership, but it continued to have severe loss of power and could not safely travel above approximately 45 mph. The suspected failure involves the engine and emissions system. The vehicle has a history of engine-related issues and previously received engine-related repairs. The current engine has developed excessive oil consumption. This condition has resulted in fouled spark plugs and a catalytic converter becoming severely restricted/clogged from oil contamination, causing significant loss of engine performance. A dealership inspected the vehicle and documented the oil-burning complaint and catalytic converter-related fault. The dealership performed diagnostic work, including spark plug replacement, but the problem continued. An independent repair facility also inspected the vehicle and confirmed excessive oil consumption and catalytic converter restriction. The vehicle remains available for inspection. This condition presents a safety concern because the vehicle experienced a sudden loss of power while traveling at highway speeds and was unable to maintain normal traffic speed.

Sunroof/Moonroof After a stop light, while driving at less than 30mph, sunroof/moonroof exploded outwards. There were no surrounding cars in front or beside or in other lane direction. It was not hot or cold out. Evening time. No weather issues. If the fabric shade screen had not been closed all the glass would have fallen all over driver. There was no warning of any kind. Glass just exploded outward into a point like a mountain peak. Then glass started falling inwards into car. Took to dealership, had insurance company evaluate for repairs, insurance approved repairs performed by dealership. Dealership service writers said this has happened on other kia's.

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
