2016 Kia Sorento Engine Problems

The contact owns a 2016 Kia Sorento. The contact stated that while his wife was driving, the battery, check engine, and oil warning lights were simultaneously illuminated. The driver reported hearing a low rattling sound and observed smoke coming from the engine compartment. The contact stated that the dealer declined to service the vehicle because the knock sensor was not installed by the previous owner. The vehicle was towed to a local dealer, where it was diagnosed with a connecting rod bearing failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 98,000.

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.

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

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.

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

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.

Mixing coolant with oil engine failure

Around 140k miles the engine started to randomly overheat. We changed the serpentine belt as well as all hoses. The engine then started to burn large quantities of oil. At 142k miles it failed all together and we are now looking at having to purchase a new engine or a new vehicle. After doing some research I read that this was a common issue with the 3.3L V6 Motors and felt the need to provide my case as well.

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).

Loss oil in big quantities headed to engine damage

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.

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 # .

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

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.

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.

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.

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.

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