My car's check engine just started flashing and the ECU has reduced my drivability to limp mode stating that my knock sensors are showing up on scan test and camshaft position exhaust sensor. When I removed the camshaft exhaust vvt sensor it indeed had metal shavings on it. A have a P1326 and a p0014 code which is basically telling me that my engine is having issue within the internal engine and oil consumption.

Excessive oil consumption by model year
What owners say
I am filing this complaint regarding a suspected safety defect involving the Theta II engine in my 2015 Kia Sorento. The vehicle developed progressive engine failure symptoms including: Engine knocking and abnormal mechanical noise Loss of power while driving Misfire conditions Excessive oil consumption Progressive deterioration of engine performance These symptoms began at approximately 150,000 miles and worsened over time. Given the documented history of Theta II engine failures involving rod bearing defects, sudden engine seizure, loss of power, and fire risk, I believe my vehicle is experiencing a progression of the same known defect. 2) Safety Risk to Driver and Public The engine condition created serious safety risks, including: Potential sudden engine failure while driving Loss of power in traffic or at highway speeds Increased risk of collision Potential fire hazard associated with Theta II engine failures Despite these risks, Kia and its authorized dealership advised me to continue operating the vehicle. I was explicitly told to “drive it until it fails.” This guidance was given despite Kia’s documented knowledge of Theta II engine defects and associated safety hazards. 3) Manufacturer Response and Denial I reported the engine failure to Kia and its authorized dealership. Kia denied coverage, stating: The vehicle had “too many miles,” and The failure was allegedly “not rod bearing related.” However, Kia and the dealership refused to provide: Complete diagnostic trouble codes (DTCs) Technician notes or inspection reports Compression or leak-down test results Oil analysis or evidence proving bearing failure was ruled out Without this information, Kia’s conclusion that the failure is not related to the Theta II defect is unsupported and unverifiable. 4) Concern of Misdiagnosis and Defect Misclassification Based on the symptoms and known Theta II failure patterns, I believe Kia may be misclassifying a progressive bearing-related engine failure as a non-covered
Faulty motor I have changed oil early every time and every mechanic I’ve been to said the Kia motor is always doing this ! I still owe 9k on this car! It’s burning oil so fast and not going into the engine this is a on going issue with these motors ! I just now hit 100 k miles no reason for my motor to be blowing please put the recall back on for the 2015 Kia’s!!!
UNKNOWN. My engine light comes on often. When I had my oil changed the professional indicated that my car is burning oil. When reviewing online, it appears that this is a common issue for Kia Sorento and specifically the engine that is installed in my 2015.
Coolant and oil are mixing. Coolant was over flowing from the reservoir. High oil consumption. Oil was just topped off about 1000 miles ago and is very low on the dipstick now. Coolant mixing with oil seems like the issue the 2016-17 3.3 V6s are experiencing with the stripped head bolts. HEAD GASKET/ENGINE FAILURE is imminent. Extend the warranty to all 3.3 liters not just 2016 and 2017 (15 years/180,000).
I don’t know why, but I keep losing oil somewhere. I do my oil changes on time regularly and they said it’s burning oil fast and that that’s an issue with all Kia.
My engine is using excessive amounts of oil. I am having to fill the engine with oil in between my 3000-mile oil changes. No oil is leaking in my driveway. I just started an oil consumption test with a dealer and after driving it 1000 miles I brought it back to them as they asked, and the engine oil level had dropped by almost 4 qt. But after making some calls with KIA regional they said they my car wouldn't have the engine replaced due to it not being in the recall. KIA knows there is a problem with their engines and will not fix the problem.
Engine has seized. Mechanic at local automotive shop stated that the engine seizure is due to engine burning oil internally. Told me to call KIA because they were aware of this problem due to safety recall. I reported problem to KIA dealership but was told there was no safety recalls relating to my vehicle. Check engine light has been coming on sporadically since 2018 along with my vehicle randomly stalling while idling in traffic. KIA was made aware of these problems and did a diagnostic, stating that the light wasn't on during inspection. And there was no reason for stalling. Also reported smell of chemical and fumes several times but nothing was found. When my vehicle reached 100k miles I was told by KIA dealer that it is normal for the check engine light to stay on due to wear and tear/high mileage. Engine seized while driving.
Low beams have completely gone out and will not work. High beams and all other lights work fine. Car Burns oil regularly. 2 quarts every 2 weeks is required now ro operate the car. I have only had the car since 2020.
The contact's mother owns a 2015 Kia Sorento. The contact stated that the vehicle was experiencing an abnormal oil consumption. The contact stated that the vehicle consumed three quarts of oil after driving 367 miles. There was no warning light illuminated. The vehicle was taken to an independent mechanic, who informed the contact that the vehicle could be experiencing an internal oil leak. The vehicle was then taken to the dealer, where an oil consumption test was performed. The dealer informed the contact to come back after 300 miles. Additionally, the contact stated that the air bag warning light was illuminated, and the front passenger's side seat belt pretensioner failed to operate as intended. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and a case was opened. The failure mileage was approximately 96,000.
The engine was inspected for a possible timing chain rattle/issue and was found to be consuming oil. The oil level was low with no obvious leaks from the engine, meaning that the engine has been burning oil for about 4 months since the last oil change at the very least. The oil consumption could cause engine to wear and fail during operation, causing obvious safety issues for this model, as is the case for other Kia models affected by a class action settlement. The issue has been confirmed by an independent mechanic, but has not been inspected by the manufacturer, police, insurance representatives or other individuals. There were no warnings of low oil levels prior to being informed of this oil consumption issue.
