What 1,237 owners told NHTSA about the 2016 Kia Sorento Plug-in Hybrid

My Sorento burned oil excessively, without warning, and now has a damaged engine, requiring replacement. This is a serious problem and common. There are two other Kia vehicles with the 3.3L Lambda engine in Weston Kia for the same problem - low/no oil and no “low oil” light. Those two vehicles and mine now require new engines. When my car experienced the problem, the car shook and the engine vibrated with a significant loss of power. This would’ve been extremely dangerous if towing anything or driving uphill. This is a common problem among Kia forums and Kia is unwilling to assist.

The specific issue I’ve encountered is that the vehicle intermittently becomes stuck in “Park” and cannot be shifted into “Drive” or any other gear using normal methods. The only workaround has been to manually engage the shift lock override by inserting a screwdriver or similar tool into the override slot near the gear shifter. This is not a normal or acceptable method of operating the vehicle and clearly indicates a failure of a system that should function reliably. Upon further investigation, I discovered that this problem is not isolated. Hundreds of Kia Sorento owners from various forums and complaint boards (including Reddit, Kia owner groups, [XXX] , and even other reports on NHTSA.gov) have documented the same problem with identical symptoms: the gear shifter becomes stuck in Park, the brake lights do not illuminate, and in many cases, this is traced back to a faulty Body Control Module (BCM). Many owners have noted that when they contacted Kia corporate or their dealerships, the representatives either acknowledged the issue was known but not recalled, or simply claimed there was no current recall to address it. This is disappointing and raises serious questions about Kia’s willingness to take accountability for systemic flaws in their vehicles. I respectfully request that NHTSA: 1.Initiate an investigation into the prevalence and root cause of BCM-related failures in the 2016 Kia Sorento, particularly those that result in gear shift locking and/or brake light malfunction. 2.Evaluate whether this issue meets the criteria for a safety-related recall. 3.Require Kia Motors to issue a recall and provide cost-free repairs or replacements of the affected components to all impacted vehicle owners. 4.Monitor any further consumer complaints to determine the full extent of the issue across other model years, trims, or vehicles using the same BCM design.

Driving on the frwy when car started loosing power/acceleration, no warning lights or indicators on dashboard. Safely able to merge off the frwy. Turned off vehicle, engine would not turn back on. But all the dash lights came up as warning including engine light. Started to smell like burnt. Open the hood and it smelled like burning oil. Towed my vehicle & under the vehicle a pool of engine oil. Dealer confirmed engine seized. When repairs began water pump was damaged & engine mounts due to engine seizing.

While driving on the highway, the vehicle engine began to shake violently. The check engine light came on. The car was driving normally prior to this moment. The car has been well maintained and is in excellent condition. I looked it up and found tons of cases that reference a judgement directive from the Theta II Engine Class Action Settlement (Case No. 8:17-cv-00838-JLS-JDE), where the warranty coverage has been extended due to known engine issues. The KSDS software update (SC260) was installed in 2023, by Kia of Orange Park. The vehicle now has approximately 127,121 miles. We towed the vehicle to Daytona Kia who diagnosed the engine as failed, but declined to initiate a warranty claim or submit the case to Kia Corporate because diagnostic trouble code P1326 was not present. I purchased this diagnostic for nearly $200 from Daytona Kia and they verified the second cylinder failed. They blamed it on a sticking fuel injector, but did not verify that this was the issue. Only stating that they believed this to be the case in their review. They did not conduct testing to rule out rod bearing failure or to verify fuel injectors were to blame for the issue. I asked for that. They checked to see if the service manager would be willing to do a BCS test on the vehicle. It was denied. I asked for definitive verification of the cause of the failure. They said I would have to pay for additional diagnostics to start that process. I contacted Kia corporate and asked them to intervene. Kia has denied my warranty claim, stating that the failure either doesn’t qualify under their extended warranty or that the lack of formal documentation disqualifies my case. In a recent interaction with the dealership, they also cited the lack of a specific diagnostic trouble code (DTC) as a reason not to proceed with warranty repairs…despite the fact that many vehicles with this engine fail without triggering that code, and the software update (SC260) was already applied.

Vehicle stuck in park. Able to use emergency procedure to drive. Repair of fault would have cost 1600.00 if not covered by my extended warranty. There is a similar recall for not requiring brake to be applied before the shifter can select a gear. This is caused by the BCM body control module. I believe that most of these units are failure prone and they control a number of functions that are related to safety.

My 2016 Kia Sorento (VIN: [XXX] ) has suffered a head gasket failure due to a known manufacturing defect identified in a Kia Technical Service Bulletin (TSB WTY035). The defect causes head gasket failure, which in my case has resulted in external oil leakage. While Kia issued a TSB acknowledging this defect, they are denying warranty repair on a technicality — stating that the failure must involve coolant entering the combustion chamber to qualify, despite acknowledging the underlying part defect. The vehicle’s engine is losing oil through the failed gasket, and the issue poses increasing risk of engine damage or sudden performance loss. Kia’s denial is inconsistent with the intent of the warranty and the federal Magnuson-Moss Warranty Act. This problem affects vehicle function and reliability. It is also being experienced by other owners of the same model and engine. I am filing this complaint so NHTSA is aware of this known defect and the manufacturer's refusal to take accountability unless the failure meets arbitrarily narrow criteria.

The electric power brake (EPB) on my vehicle had a fault three separate times. The first time, the rear brakes were engaged by the EPB for approximately a half an hour. The second time a few weeks later, they stayed locked for approximately one hour. A few weeks after that, the brake locked up while the car was parked, and would not release for almost 7 days. It isn’t the fault itself that is of the greatest concern. It is the fact that there is no apparent emergency release for the parking break. I’m grateful I did not need to use the car to drive my kids to the emergency room, for example. I’m very surprised and disappointed that Kia, throughout all of their other innovations, does not have an emergency EPB/brake release handle. One could easily be put in the back of the car, near the spare tire, with a cable and set of release pins, which when pulled, would release the EPB and the car could be driven.

I own a Kia Sorento with a recurring electrical wiring failure that affects the passenger-side blinker and hazard lights. The issue has been “repaired” multiple times, but it returns within a day. This prevents me from safely signaling lane changes or using hazard lights in dangerous situations. The wiring becomes loose or faulty repeatedly, creating a persistent safety hazard. This defect has not been permanently resolved despite multiple service visits. I am concerned for my safety and the safety of others on the road.

he component that failed was the engine. Specifically, the engine block burst while the vehicle was traveling on the highway at over 50 miles per hour. The explosion of the engine block during driving posed a serious risk to my safety and that of other drivers. The sudden failure could have caused a loss of vehicle control, a collision, or even a fire. Fortunately, I was able to stop in the emergency lane in time without causing an accident. The issue was confirmed by an independent mechanic, who verified the structural damage to the engine block and its complete loss of functionality. At no time before the incident did any warning lights—oil or engine—come on. There were no messages on the dashboard indicating a potential imminent failure. The engine is available for inspection if necessary.

I was driving my Sorento SXL on a highway, at approximately 50 mph. With no warning, the engine began to run rough. The check engine light immediately began flashing. I was able to drive the car approximately three more miles to an auto service center. The engine ran very rough the entire time, wanting to stall when slowing down. The mechanic determined that my car’s oil reservoir was 4 quarts low, yet no engine oil light ever illuminated on the dashboard. It holds 6.2 quarts, and had only 2.2 quarts in it. Again, there was no illuminated light whatsoever telling me my car was dangerously low on oil. Because of this low oil condition, one of my timing chains skipped, and the cam rotated approximately 62° out of center. That’s what caused it to run rough. It appears my only options now are to have the engine apart, and hope no real damage was done, or replace it entirely. The engine for my car has been discontinued, with seemingly no suitable replacement from Kia. This could have been completely avoided if my car had alerted me to a low oil condition sometime before. This is very dangerous and it seems it is a common ailment among some Kia cars like mine. A low oil light would have informed me immediately that my car was in need of oil, a critical fluid for proper and safe operation. If I were towing a trailer when this happened, or on a winding stretch of road in snow or ice, this could have been catastrophic.

My wife was taking my granddaughter to her dance recital on 06/14/2025 she went to pass a car and the Sorento started missing out then died. She had to get to the side of the road and call for help. Once I arrived, I noticed oil on the ground under the vehicle. After I had my mechanic look at the car it was determined that it threw a rod out bottom of motor and the car was towed home. This is a 2016 kia sorento LX with the 3.3 motor. We have had no issues with this car and it has had regular maintenance perforemd since we purchased it at 27000 mikes. It now has 11000 miles warranty ran out at 100000

Put vehicle in park while waiting at a gas station. It won't come out of park. Managed to get it to the pump, and used a screwdriver to bypass the shift lock control, and was able to drive home. With the bypass enabled, it puts my family at risk while driving. The car can shift without the brake being applied. I looked this problem up and it is extremely common with Kia Sorento (the BCM fails, and it's not an affordable fix).

Engine failure

1) I bought this car in October 2021, when it had ~79,000 miles on it. After ~2,000 miles, it showed a low engine oil sign, and it has been showing this issue since then, i.e., I have to change my oil/filter after every ~2000 miles. It has incurred a huge cost. I talked to the dealers, but they did nothing to solve this problem and charged me ~$1200. Funny part. Whenever I go for an oil change, they say that KIA/HYUNDAI cars have this engine problem. It's a joke to this system that the Govt still allows them to roll on the USA roads. 2) Today, this car had a flashing engine light. I will go to a mechanic tomorrow, but afraid of how much they will charge.

As I drove on the highway, the car made a loud rattling sound and all the lights on the dashboard lit up. I pulled over immediately and turned off my car. I let it sit for a few minutes and tried to turn it back on - it would not start. I was on the side of a 4-lane highway in the early evening, with my 3 children in the car with me. I had the car towed to a mechanic - they discovered the oil tank was completely empty - I was not overdue for an oil change. They conducted an oil change - the car started and then immediately the engine seized and shut down. However they could not conclude what happened to cause the engine to fail. I took the car to the Kia dealership for an evaluation. The engine had seized due to bearing failure (bottom end). There is an open class action lawsuit and engine warranty for the same system failure, but on a different-sized engine. There were no warnings of an engine failure or a problem with the vehicle prior to the engine shut-down. It all happened within a matter of seconds as I was driving. The transmission, catalytic converter and flex hose had been replaced 8,000 miles prior to this incident.

The shift interlock system stopped allowing the car to come out of park however the vehicle would still roll when in Park, have to do a manual override to take it out of park but it will hesitate on the highway. I have had too many near miss accidents with this vehicle. Especially due to my break lights working intermittently although they've been replaced. I'm not sure if it's electrical (my locks would randomly lock and unlock) or due to the shifting gear.

Steering wheel has a "sticky" feeling when driving at high speeds. You have to keep the steering wheel moving back and forth or else it sticks while driving high speeds. I have reported to dealership multiple times, but I have been told there is no issue.
