2016 Kia Sorento Engine

3 times head gasket has been replaced and repaired and every time oil is changed, they say I am losing oil

The contact owns a 2016 Kia Sorento. The contact stated that after starting the vehicle, while driving to the residence, the coolant temperature gauge went from COLD to HOT. The contact inspected the vehicle and became aware that smoke was coming from the engine compartment. The contact waited for the engine to cool down before driving to the residence. The coolant reservoir was extremely low, and coolant was added; however, the engine continued to smoke, and the coolant reservoir was empty after an hour. The vehicle was taken to a certified mechanic who diagnosed and determined that coolant was leaking from the coolant reservoir. The coolant reservoir was replaced; however, the failure returned within 5 minutes of restarting the vehicle. The mechanic then diagnosed the vehicle with complete engine failure. The vehicle was towed to the dealer, where the contact requested information on a Limited Extended Warranty Extension and a recall; however, there was no coverage for the repair. The vehicle was not repaired. The manufacturer was informed of the failure and opened a case. The failure mileage was unknown.

My 2016 Kia Sorento with 2.4L GDI Theta II engine began consuming excessive oil despite regular documented oil changes. At approximately 86,000 miles, the engine failed and requires full long block replacement. The vehicle has been at a Kia dealership for 5 months while I went back and forth with Kia Corporate. I was quoted over $8,000 for replacement. Kia has declined assistance. This appears consistent with known oil consumption and bearing failure issues in the 2.4L Theta II engines. This failure occurred without warning and creates a safety concern due to potential engine stall while driving.

The engine stalled while driving on the expressway. Myself and my daughter and her friend were in the car. The vehicle started right back up, and I was able to drive the car home (less than 2 miles away). The following day, my wife got an oil change, and went on the expressway, and the engine stalled again causing her to have to navigate the car, with no engine power, to the side of the highway and wait for myself and a tow truck. Both times were very dangerous. We had the vehicle towed to a mechanic, who said the crank shaft & rods and bearings for the engine look like they failed and seized up, causing the engine to complete lock up and stall, requiring a full engine replacement. Kia is refusing replacement saying we are not covered by the previous complaints and concerns, stating our vehicle is not covered specifically, stating that the 3.3L engines were not covered under the previous recall/extended warranty offered on engines in the same yr/make/model as our vehicle. The check engine light came on, and there was a slight knocking sound as the car was idling just before the engine stall, and as the engine stalled, the oil lamp and the battery light came on. This happened both times. The symptoms appeared just before complete engine failure. We get the vehicle serviced at Kia, and had the oil changed by Strickland Brothers the day of. We were concerned that the engine light came on due to potential of the oil needing to be changed. We do not have any electronic files or reports for this issue yet.

The vehicles is showing all this codes P0340, P0365, P0780, PO010.

The contact owns a 2016 Kia Sorento. The contact stated that while the vehicle was idling at a red traffic light, the temperature gauge went from the normal engine temperature to HOT. The contact turned off the vehicle and allowed the engine to cool down, and the gauge returned to normal. The contact continued to drive. The following morning the contact inspected the vehicle while parked at the residence and while checking the radiator cap, there were no noticeable issues found with the cooling fluid. The dealer was contacted and informed that the thermostat had fluctuated; however, there were issues found regarding the fluid. The vehicle was towed to the dealer, who informed the contact that Stop Leak might have been used in the radiator to prevent a leak. The dealer diagnosed the vehicle with head gasket and radiator failure and stated that both parts needed to be replaced. The dealer informed the contact that there was copper in the engine and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and opened a case. The failure mileage was approximately 74,000.

Failed oil pressure switch and now my engine is no good

Engine suddenly started making a lot of clattering noise. Oil consumption has been extremely high! Mechanic stated engine needs replaced.

got into my vehicle pushed button to start, could hear a clicking for the first few seconds, then clicking went away. Drove off, went approximately 0.30 mile at a stop light when started to go it stalled in the the middle of an intersection. No warning light no other warning of anything wrong with vehichle, no other warning signs that there could be anything wrong. In July 2025 I had just took vehicle in for a major maintenance, oil, air filters, spark plugs, timing belt, and I checked oil and again no warning signs that there was anything wrong with vehicle. Took to a shop, mechanic believed it was the key fob, due to immobilize, had a new key reprogrammed and still not start, then proceeded to check the starter and installed a new starter still not start and found to be engine siezed.

Additionally, the contact stated that the vehicle vibrated while being turned off. The vehicle was taken to AutoZone, where unknown diagnostic codes were retrieved. Additionally, the contact stated that while driving 40 MPH and depressing the accelerator pedal, the vehicle failed to accelerate as intended. The check engine warning light was flashing continuously. The vehicle was taken to an independent mechanic, where it was diagnosed that the fuel injectors had failed, and the cylinder #6 spark plugs were replaced. The contact stated that the failure persisted. The vehicle was taken to the dealer, where it was diagnosed with oil intrusion into the engine and the cylinders. Additionally, the contact was informed that the vehicle was experiencing excessive oil consumption. The dealer determined that the cylinder block assembly and the engine needed to be replaced; however, an unknown spark plug was replaced. The vehicle was taken back to the independent mechanic, where a scope with a camera was used to inspect the cylinders, and no oil was found; however, the failure persisted. The vehicle was not repaired. The manufacturer was made aware of the failure and advised the contact that the vehicle needed to undergo an oil consumption test. The contact was advised to drive the vehicle for 1,000 miles. The contact had parked and had stopped driving the vehicle due to safety concerns.  The failure mileage was approximately 75,000.

Lost motor power while driving. No warning light before engine failure.

Mixing coolant with oil engine failure

My 2016 KIA SORRENTO consumed all oil resulting in engine (3.3L Lambda II) failure within 72 days (3,442 miles driven) of Kia dealer service department complete inspection and service (including oil).

Over heating , loss of heat in the vehicle , oil in the radiator fluid so possibly a bad head gasket car has 121000 on it

Loss oil in big quantities headed to engine damage

The engine failed. Had a new engine put in the car. Driving the car home the car lost power on the interstate causing me to almost get hit by a semi trailer. Called Kia Dealership and was told to bring car back. They said it had a bad high pressure fuel pump. I had it replaced, same issue. They said they would not fix the engine to take it somewhere else. Called Kia of north America to report the safety issue and I didn't feel safe driving the car. I wanted the car to be bought back. They denied it and would not honor the warranty. They said i could not file a lawsuit against them? Engine is bad. I sent a written statement to Kia of American with all paperwork notarized.

Engine seized up while driving. I had just visited the dealership and had 5 RECALLS done.

The contact's wife stated that on a separate occasion while starting the vehicle, there was an abnormal sound coming from the engine. The vehicle was taken to the local dealer where it was diagnosed that the battery had failed. The vehicle was not repaired. The dealer jumpstarted the vehicle. The contact stated that the failure persisted. The contact's wife stated that on a separate occasion, while stopped at a traffic light, the vehicle stalled. No warning lights were illuminated. The vehicle was towed to the residence. An independent mechanic arrived at the residence and diagnosed the vehicle with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The Extended Warranty field technician later informed the contact that the repair could not be covered since the knock sensor was not installed back in 2021. The contact related the failure to NHTSA Campaign Number: 18V907000 (Fuel System, Gasoline, Engine). The failure mileage was approximately 62,598.

Received a notice of extended coverage regarding engine block concerns in September of 2024 took the vehicle in regarding a constant coolant smell when driving the vehicle. At that time the dealership checked out the vehicle and then proceeded to charge us for the appointment, even though the warranty extension clearly stated there was to be no cost incurred. After receiving the vehicle back we still experienced coolant smells while driving and informed the dealer accordingly. On [XXX] while driving to Henrietta Ok, the vehicle actually overheated while driving. We had to have the vehicle towed to our home. On Monday morning I contacted our Kia dealer and let them know about the event. On [XXX] we trailered the Kia back to the dealer, after I had performed the appropriate tests the dealer would be performing to verify a block issue with the vehicle. Once the vehicle was at the dealership they performed the same test with the same results I had received. They submitted their video evidence to Kia motors , at which time Kia motors requested a second block test be completed as they questioned the results. The dealership tried to duplicate the results to no avail. At this point Kia is not authorizing an engine replacement. We are three weeks into a process that Kia is well aware of the issue, but they will not authorize a repair.

While driving the vehicle started making loud engine noises. Contacted the extended warranty department and got the car in the shop. The engine had blown and had metal in the oil pan and oil filter. The car had a fresh oil change and showed to have a clean maintenance history. Just purchased the car a month prior. Warranty covered the replacement of the motor.

The intake valve cam Engine Variable Valve Timing (VVT) Sprocket pin wasn't properly seated in the phaser and worked its way out. Additionally, the corresponding hole in the camshaft was machined too deep, allowing the pin to completely depart the phaser and move into the camshaft. This resulted in no control over valve timing and the Bank 2 camshaft over-advancing the intake valves to 63 degrees from standard. This is under-engineering of critical engine parts and poor quality control by Kia. It caused the engine to go into "limp home mode" with a significant reduction in power and a flashing check engine light. Had this happened towing a trailer, or in poor driving conditions, the vehicle may have been difficult to control and put occupants in danger. The pin was found completely inside the camshaft. There seems to be low quality engineering with this manufacturer, as there are many reports of these known problems.

I am receiving an engine problem on uvo. I took it to autozone to run a diagnostic test and states cam sensor engine problem. It is using excessive oil. I keep my engine oil changed consistently on time. It is not making it to the next oil change date before I have to add oil. This is my main source of transportation and I am on social security and cannot afford engine failure repair. This should not be happening since I have my oil changed consistently. Please advise.

My KIA, engine just died. I was at a stop light, the light turned green I pressed on the accelerator to go and at the middle of the intersection the engine died. Not certain what had happened or why the engine would die. After a week I had the vehicle towed to a car shop. The same shop that had just done a maintenance on the vehicle in July 2025. I have attached the copy of receipt from the work that the shop had done. When they looked at it they thought at first it was the key fob, so a new key fob was done, it still did not start. Then it was thought to believe it was the starter, so a new starter was installed, vehicle still did not start. At that time I was advised that it was the engine that had siezed. My complaint is that there was no warning signs or signals in the vehicle of anything mechanical going wrong or needing any kind of attention. No warning light displayed on the dash. I drove the vehicle not knowing why would my engine just die, my miles is between 175,000 - 178,000 so the last thing I would think to happen is my engine siezing up on me. Warning lights give you something needs to be looked at and figured out. But as a safety you get nothing displayed then your engines just dies, anything could happen when you are in the middle of traffic, highway or even if it was in the middle of the train tracks. I had spoken to KIA Dealer Service and he advised my vehicle does not have an engine recall but there were a recall in the past for engines such as mine. The KIA Dealer Service advised that they would have to do an inspection, at a cost of $270.00 dollars, and unfortunately it would have to be towed. Advised me that if I wanted to get a new engine it would cost $12,000.00. The vehicle is available for inspection just need to be towed.

Just bought the car, was perfectly fine during the test drive, no lights on or engine codes present. On my way home check engine light came on showing code P0420 , catalyst system efficiency below threshold (bank 1), saying the catalytic converter needs to be replaced. Did some research and found there were certain 2016 Kia Sorentos recalled for this issue, but doesn’t show up on affected vehicles list when I look up my VIN # .

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.
