I have filed a complaint with the South Carolina Attorney General which is pending and spoke with KIA Consumer Affairs twice about the failure of the Knock Sensor device which has caused engine failure in my 2016 KIA Sorento. I was told by KIA Consumer Affairs that the Upgrade Knock Sensor Campaign was mailed to the first owner of the vehicle in 2018 and was not replaced. I bought the SUV in November 2019 from Carvana. I have the original carfax report which states No Recalls on my SUV. I had no knowledge of the knock sensor upgrade Campaign and of course didn't receive a Recall notice. The only Recall notice I have received, just recently, is for a wiring harness for tow hitch, however, I don't have the tow pkg./hitch on my SUV. Until my engine failed due to the knock sensor, I had no indication of anything being wrong with the SUV. KIA refuses to pay for the engine replacement. My SUV is still at the dealership service dept. until this is resolved. I am a [XXX] lady with 32 years Federal Service with the Veterans Administration in SC. I do not have the money nor should I have to pay for the engine replacement. It's a lot of money! I am appealing for your help to force KIA to take responsibility and replace the engine. When the engine died without warning, I was in a dangerous intersection, during rush hour. An off duty police officer assisted me with directing traffic & obtaining a tow truck to pull me safety until AAA could come tow it. I called the dealership the next day, on [XXX], & was told why they thought the engine died & that warranties on the motor had been extended to 100,000 miles to cover it. I was told to have it towed there. A couple days later a technician called & said he did not think KIA would cover it because the knock sensor was not replaced during the "Recall." Any assistance you can provide is appreciated. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine (I think engine) stalls out, and several times the engine has completely died. Almost causing me and the other car involved a very serious accident. The vehicle stalls when sitting at the traffic light and I go to turn to accelerate and it stalls and after pushing/tapping the gas pedal repeatedly it will eventually stop and I'm able to then drive on. Also the car does not shift properly at all, it winds up and seems the get stuck and have to try accelerate before it shift. I keep getting errors on my dash saying "possible engine condition, please press schedule service" and then I run the diagnostic report and this is what it says CATEGORY (2) PowerTrain P0456 Evaporative Emission System - Leak Detected (Very Small Leak) Possible condition(s) with your Engine Control System has been detected. KlA recommends a full system check when convenient. To schedule an appointment with a KIA dealer, select Schedule Service on the screen. P0303 Cylinder 3 - Misfire Detected Possible condition(s) with your Engine Control System has been detected. KIA recommends a full system check soon. To schedule an appointment with a KIA dealer, select Schedule Service on the screen. Request Appointment I have taken my vehicle in the KIA Service Center twice and have given them the errors and described the issues I am having along with several other issues. The Kia service department has failed to provide me with a resolution to the problem stated above or any other issues I reported. They didn't even check oil as I requested. They advised me the oil levels were "fine" but once I checked it myself it was actually low, proofing they did not do any type inspection on the vehicle as requested. The advised me that there was nothing they could do about the stalling of the vehicle or the engine shutting down because they couldn't duplicate it. I'm not sure exactly what they are meaning by the statement. I then called KIA corporate number and the representative submitted a case onveh

- Beckley , WV, USA

The contact owns a 2016 Kia Sorento. The contact stated that while driving at approximately 55-60 MPH, a loud explosion was heard coming from the vehicle. The vehicle then lost motive power. No warning light was illuminated. The contact pulled over the side of the road. The vehicle was towed to an independent mechanic, who diagnosed that there was a hole in the bottom part of the engine, causing oil to leak from the engine. The dealer informed the contact that the engine, starter, and exhaust manifold needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure, and a case was opened. The manufacturer denied the engine replacement. The failure mileage was approximately 119,000. The contact stated the safety issue of the vehicle losing all power without warning while driving is due to a specific engine that Kia installed in several of its cars/suvs. It is called a Theta II engine that was used in 2.0 and 2.4 liter cars.

On Wednesday, March 6, 2024, I was driving my vehicle to work. I have a 12 mile commute and take both highways and local roads. When I started driving, I noticed that the engine would make a knocking/rattling sound when I accelerated. While in the final mile of my commute, I stopped at a stoplight. When the light turned green and I applied my foot to the accelerator, the vehicle did not respond and dashboard lights for the oil, engine and battery all illuminated. These lights did not illuminate at anytime prior to this point. Being that I was on local roads, I was able to coast the vehicle to the side of the road. I turned off the engine and attempted to restart. The engine did not start but all other electric components in the vehicle appeared functional. Roadside assistance attempted asses whether the vehicle had a dead battery using a portable battery back but were also unable to start the vehicle. The vehicle had to be flatbed towed to the dealership. After a week, I was informed that the engine had seized and was non-responsive. As of this date (3/18/24), I am still waiting for backordered parts and do not have an ETA for the return of my vehicle. I also have not been provided a loaner.

Check engine light turned on. The crankshaft has given out and the mechanic confirmed it needs a new engine. Cylinders 2&4 are misfiring. It has a rough idle and does not accelerate. Many online forms confirm that this is a Kia problem and different years have had a recall. I can not drive my car due to the shaking of the car and the unknown of possible breaking down. It revs up high before it shifts gears and shakes.

In December 2022 while driving at various speeds, the vehicle began to overheat. No warning lights illuminated. I pulled over and let the engine cool down. Then coolant was added to the reservoir. I waited before restarting the vehicle. I took the vehicle to an independent mechanic the next day and was informed that the head gasket was blown, and the engine would likely need to be replaced. Kia dealership was contacted and notified. The vehicle was not repaired.

- Averill Park, NY, USA

The engine overheated. We were able to get to a place and stop. We continue to have overheating issues. An independent shop believes it is being caused by the issue of stripped head bolts. They advised I take it to the Kia dealer who denies being able to recreate the overheating. No further inspection has taken place. The temp gauge was topping out but no other warning lights or gauges were triggered. After reading numerous other accounts of issues with this engine in this car I was concerned about continuing to drive the vehicle for fear of being stranded or the engine seizing while driving.

I was driving on an interstate coming down a mountain and my car stopped accelerating. The check engine light also began flashing. I glided along the interstate to the nearest exit. I had my car towed to a mechanic who told me my engine blew due to a defect in my engine. Months prior to this incident, my car would not retain oil so I took it to Kia and they replaced my oil gasket thinking that was the issue. However, it turns out the problem was with a defect in my engine. This is a very dangerous issue. Please please recall these cars.

My 2016 Kia Sorento 3.3 L V6 starting over heating and smoking and loss of power and would no start when it was running hot. In January of 2023. We towed the car to Kia and they could not find the problem told us we need to replace the thermostat for $1000 and that would fix the problem we left and had it towed away. We took the car to a radiator shop two days later and they change the water pump and thermostat. The overheating continued we took it back to the radiator shop and they performed a head gasket pressure test and the car failed and they said the head gasket was leaking and we need to get the heads repaired they quoted $6900. We later took the car to a engine rebuilder and they certified that the heads gasket was blown with the same test and the bolts were wore off on the cylinder heads and the engine needed to be rebuilt or replaced. We went to Kia they did not do anything. We had to get the engine totally rebuilt on our cost total cost $4712.04 and it took 3 months to find all the Kia parts. KIA issued a letter to cover the repairs for these engines and this model on Janurary 2, 2024 and it and has not been paid it has been sixty days which was there time frame in the letter to cover the claim they won't answer us at all with a verdict the most terrible car company around.

Driving on freeway and car suddenly would no longer accelerate over 40mph. Pulled off the freeway and large amounts of white smoke was coming from the exhaust. Turned off engine, looked under the hood and saw engine coolant bubbling. Attempted to restart car and it would no longer start. The car was towed to a Kia dealership and diagnosed as head bolts backing out of cylinder head causing leak and pressure with coolant and oil mixture. I was told my engine would need to be replaced.

My name is [XXX] Owner of KIA SORENTO 2016 V6 At the begging of this year in early January, my automobile starting showing extremely overheating conditions. My wife was taking our kids to school on a cold weather, 15 minutes from home and as she was arriving to the school parking lot she noticed the temperature indicator up to (H) mark, she then notice a loud buzzing sound coming from the engine.She parked the car immediately as she could, shutdown the engine and asked my kids to leave the car immediately. She called me very frightened and worry about my kids safety and hers. She said that she was able to shutdown the engine but the temperature indicator stayed on H mark and the buzzing sound was still on. Then, I remember receiving a latter from Kia Corporate Headquarters, extending the warranty on my car on mid December 2023. The letter states that the warranty has been extended because it's a potential overheating and coolant leaking that it has been related to the cylinder head gasket and head bolts. We reached out to a dealer right after the incident and on [XXX] we took our car for inspection and acknowledge the mechanical problem. All the sings of the fail system of the engine are present in my car. My car has been at the dealer since [XXX] and as of now Kia Corporate has fail to proceed with the approval of the repairs of my car. I have been renting cars all this time and the dealer personal said they can't approve to pay any rental until Kia Corporate Headquarters acknowledge the fail engine. Its absurd that Kia Corporate Headquarters have the knowledge of this dangerous mechanical issues in my car engine but fail to acknowledge repairs. The case it's no longer" to be determine" on their data base, its updated to repair as fallow but yet has not acknowledge that our car has to be fix under their extended warranty and my wife still driving my kids on a rental car.

While driving the car, the engine temperature started fluctuating and finally reached over temp. The engine failed. I towed the car to my mechanic and initially thought that the head gasket had blown. However, upon inspection, they found that the engine head bolt to the engine block was damaged. The threads were stripped. The only repair option for this problem was to replace the engine block. I believe the engine on this vehicle is a 3.3-liter Lambda II V6. This car only had 87,000 miles on it.

The contact owns a 2016 Kia Sorento. The contact stated that the engine was empty of engine oil a week after an oil change. After oil was added, the contact's husband observed that a quart of oil had been consumed in a few days. The vehicle was initially taken to an independent mechanic, and it was discovered that excessive oil sludge and hard carbon build-up was in the valve and stems. The contact was also informed that the piston rings were worn and that there was scoring on the cylinder walls. The contact also stated that while driving at 55 MPH, the engine oil warning light flashed on the instrument panel and the vehicle stalled. Due to the failure, the vehicle was towed to the dealer where it was diagnosed with piston failure and a misfire in cylinder #2. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 142,000.

- South New Berlin, NY, USA

The Engine failed at 79,000 miles due to the known defect with their 2016 Kia Sorento engines. Kia is unwilling to honor their recall due to not completing what they refer to as a Product Improvement prerequisite. Kia admitted these Product Improvements are only communicated to original owners and not published through any recall so a consumer that purchased a pre owned vehicle would have no way of knowing about this unless they ask for it specifically at a Kia dealership.

- Riverview, FL, USA

Engine failed Kia decided that part is Not covered under warranty and dealer expects us to pay $6500 This car is only 8 years old, 88,500 miles. How can Kia sell faulty engines and still expect someone to pay outrageous price to repair their junk cars?!

- Franklin, MA, USA

turbo feed pipe, high pressure fuel line, oil feedline gaskets, oil return line gaskets, turbo oil feed line. problems started happening in 2016 with turbo. 2020-2024 seem to be having problems with turbo lines and oil lines and nothing seems to be connected. in 2020 something happened and lost oil but no lights came on. also, have had more recalls on this vehicle than any other one i have owned. if there is a problem with this engine or turbo, i just wanted to have my concerns recorded.

- Greensboro, NC, USA

It was determined by a local mechanic that the engine was damaged due to a internal rod busting through the block of the engine. This caused an immediate shutdown of the vehicle in the middle of traffic on a cold night with my 7-month old daughter in the vehicle. I suppose it could have been worse if the engine had caught fire or if we were on the highway, thankfully we were barely accelerating from a stop light. The engine has not been inspected by Kia as they claimed it would cost over $300 to just look at it, and it is well known from the original mechanic what the issue was. We did contact Kia about it but they were unwilling to fix the issue. We were quoted over $10000 for a replacement engine but that was all the help we got. Prior to this sudden destruction of our engine all normal oil changes and maintenance had been done and there were no warning lights on the dash.
