2016 Kia Sorento Engine Problems

Upon a catastrophic engine failure Tasca Kia replaced engine under Theta II settlement. I picked up my kia on 9/12. Engine is not running properly. It’s jerking and there is loud mechanical knocking. I don’t feel safe driving. I’ve contacted Kia corporate beginning 9/16 who contacted Tasca to arrange for tow and loaner. They said Tasca service mgr would contact soon to set up. They never did. I called corporate again later that day and after they called Tasca they were told service mgr went home for the day. As of this date Tasca Kia has not contacted me. I again called Kia corporate 9/17 asking to please escalate and allow me to use another service dept. The only other service location with loaner is a half hour away and I cannot afford another tow or another rental. I am stranded with a car that is not safe due to installation failure or another defective engine. No one from Kia will help in a reasonable time frame. I’m now told it can take up to 48 BUSINESS HOURS for any assistance. In the meantime I’m being forced to decide on whether to risk driving an unsafe vehicle to the service dept or to continue waiting for Kia to contact me.

I am filing this complaint regarding a 2016 Kia Sorento, VIN [XXX]. The vehicle suddenly broke down while my [XXX] daughter was driving in [XXX] and was taken to Sooner Kia in [XXX]. The dealership diagnosed the engine as seized and stated that it failed because there was no oil, requiring engine replacement. We dispute that conclusion. Within approximately five minutes of the breakdown, my daughter checked the oil at her father’s direction, and the level appeared normal. A mobile mechanic later inspected the vehicle and also reported that the oil level was normal and appeared clean. Sooner Kia now claims the engine was “bone dry” and that lack of oil caused the seizure. We have requested documentation showing how much oil was found, whether any oil was drained, what testing was performed, what internal damage was identified, and what evidence proves that oil starvation caused the failure. We have not received documentation establishing the cause. This is concerning because NHTSA previously investigated loss of motive power involving 2016–2017 Kia Sorento vehicles with 3.3L Lambda II engines under PE23-019. Kia later created extended warranty campaign WTY035 for certain related failures. Please document this complaint and review whether this engine failure may be related to those known issues. We are being asked to authorize an expensive engine replacement without evidence supporting the dealership’s conclusion.

Incident

Aug 30, 2026

On or about XXX, my KIA Sorento LX FWD Auto 2.4-liter engine with an approximate mileage of 36,000, began having drivability problems, none of which occurred before that date. On XXX the vehicle was serviced at Ourisman Chantilly Kia (VA051) for a Voluntary Emissions Service Campaign (SC340) THETA II 2.4L GDI ECM S/W Upgrade. Records reflect that it was a Theta II Emissions Logic Improvement 250A21R1 0.3 M/H. This was a voluntary campaign from Kia America, Inc., [XXX]. Failure to have this performed, as cited from the Kia Corporate Headquarters, could nullify warranty/warranties. What ensued was a vehicle that stalled, seized, hesitated, and/or jolted at low speeds that had the potential to cause severe injury or accident. Uncontrolled rough accelerating and seizing is a serious complaint, and the causation can be linked to the dealership performing the voluntary recall where the vehicle was purchased on March 15, 2015, in [XXX]. Further, this vehicle has a full and complete record of all repairs and symptoms, which includes, and is not limited to, maintenance, Service Campaign, Service Action, Recall, and Product Improvement. This vehicle, included in a class of vehicles with a history of potential engine failures, has a Lifetime Engine Warranty extension coverage included in PI1802 Y/Z Engine R&R Warranty Bulletin 2020-26 and PI1802W/X Warranty Bulletin 2018-10. Therefore, when the records were reviewed for the initial Voluntary Emission Service Campaign recall code SC234 completed in 2022, along with my former NHTSA Complaint Number XXX submitted electronically, an apparent history of obfuscation relating to material safety concerns emerges. KIA America, Inc. sold this Kia as a five-star safety rated vehicle. It now makes me feel uneasy with its defective drivability.

I went in a few months ago for a routine oil change. My car has had zero operating issues since I had the engine replaced around 5 years ago. They told me that I need to have a voluntary emissions update performed, so I gave consent. (The letter I received a few days later referred to it as "Voluntary Emissions Service Campaign.")On the way home, it seemed to drive rougher. I figured it was relearning some of the basic operating values. The following morning, it idled rough and then when I began driving, it would lurch forward irradically for the first one or two minutes of driving. I called the dealership and they insisted that it was coincidence. They said they will look at it, but there would be a charge. I have noticed a pattern since then. During normal driving, it is now smooth. It only happens on cold starts. Allowing it to idle elimiates the issue. However, it continues to idle rough on cold starts. If I drive it after it warms up, however, it does lurch forward. After this, it drives normal. Today I went in to the dealership for another oil change and asked about it. They continued to insist that it was impossible, but that I could leave it overnight and pay to have it looked at with the understanding that the two cannot be related. The safety issue is that it will literally make the car lurch forward when barely touching the gas. If this continues to worsen, it will cause a wreck. It has not been formally inspected, but I can provide dash cam footage.

While I was driving, my 3.3 V6 engine on my 2016 Kia Sorento seized up with no warning. There is no visible oil on the dip stick, although I have changed my oil routinely. There has never been visible oil outside of the engine or on the ground. I never had any warning light come on. I believe the engine burns an extreme amount of oil, which is putting people in a dangerous situation and financial hardship.

On Saturday the 18th of July, the car was fine, on Sunday 07/19/2026 got ready to take car to regular scheduled oil change and it was making a blown engine noise, the rod had failed, Safety issues where the people at oil change could have had a rod thrown out the bottom of the engine, or my car could have failed in the middle of the road causing an accident. No warning signs, no limp mode, no engine light, no noted metal in oil on previous oil changes. Inspected at Kia, does not meet any recall warranties, however service manager at West Hills Kia stated this is in an internal engine failure and should not have happened with our service records and care of vehicle.

I recently took my 2016 Kia Sorento L to the Kia dealership for the Emissions update recall. The next day when I started it up and put it in drive, it started jerking hard when I was trying to speed up (going from first to second gear). I had to stop and then slowly push the gas so it wouldn't jerk so hard, then it finally switched gears and was smooth. Ever since it's happening only at the first cold start up of the day, and have sluggish acceleration throughtout the day. No lights on or codes. I took back to dealership twice and they said they couldn't replicate it and so they aren't sure, but it definitely still does it (anyone riding with me notices before I even mention it).

I took my 2016 Kia Sorento to the dealership for an emissions service update as a result of a service bulliten (SC340) After recieving the car back, the transmission acts unpredictably and the throttle is erratic. This happens when started cold and continues until the engine reaches temperature. It did not do this previous to the update. It is a safetey hazard and almost caused a collision. The throttle response was sluggish, it hunted for gears and as a result I was unable to safely merge into traffic endangering myself and other drivers.

(Transmission and motor) I had taken my car to the dealership on XXX for recalls and all the signal were fine before going there. They took my car back to do the recalls and my son and I waited . Once they were done we left closer to closing time is noticed there was a burn mark on my dash board that wasn’t there before the recalls. Going forward on the way home. We were waved down by a man stating that my signal and brake light weren’t working . So that next day we took my car back to the dealership to see what happen, why all the sudden different alerts were coming up. They had the same mechanic relook at the car and a when finish 31/2 hour latter was told I needed a new transmission, costing $7384.94 which I don’t have . They charge me $179.00 just to confirm what they said about needing a new transmission. I was devastated and confused why I wasn’t told that the day before. So a few days later I took it to another machanic to see if the could see why the lights weren’t working and he ended up putting new bulbs in and got them working but also he put it in a diagnosis machine 2 of them and couldn’t get a reading at all and said I should take it back to find out why he couldn’t get a reading. I was so frustrated at that point I just was upset! I then had a friend of the family mechanic look at it and he said it wasn’t the transmission it was a knock sensor that I needed so I ordered it. When I called him to install the knock sensor he was too busy to do it and it had already been a whole month of waiting so I reached out to a place in Cumberland RI to see if he could install the knock sensor had it towed there and he kept it for three days and said it was a transmission computer and he tried two of them and neither of them worked and charged me $150 for that I was humiliated and crying , I went there to have my car towed home seen him while waiting for the tow truck to come he said I needed a new transmission and now a motor, crying again.

Car completely stalled while on the freeway with no warning, no engine lights, nothing….luckily we were going downhill and were able to pull over to the side safely. Still owe 6k to the finance company but mechanic claimed I needed a new waterpump…after being changed and charged the car still wouldn’t turn on despite the new waterpump….and a bunch of new obd codes showed up & now I need a new engine. After a lot of research I’ve learned this car is notoriously known for many recalls and overall complains…..I wish I had done research before buying it, now I’m in debt for a car I can’t even drive

May 28, 2026

At 116 miles, the engine blew and I was informed it would need to be replaced. I purchased a used engine from the same year of vehicle because Kia said it would not be covered since the vehicle had passed the 100,000 mile mark. I spend over $5,000 to get this engine and have it installed by a licensed mechanic. This second engine has now also blown leaving me without a vehicle as a single mom with a child who has a medical disability. Kia does not have a recall on this engine, which is clearly faulty. There is no way for me to come up with the funds to replace this engine for a second time and is something that should not even have to have to be figured out. I have been in touch with multiple mechanics who say the only way to repair is to replace as it would cost way more to try to rebuild. Kia should stand behind this as they know it is an issue.

While driving my vehicle the engine seized one day, i brought to the kia service center where they took at apart and the dealership claimed Kia should replace the engine under warranty as well as known issues with these vehicles. Corporate Kia denied the claim sent in by the dealer. And sent me a bill for the cost to replace the entire engine.

I bought this used with 113,000 miles on it. Within the first year, I had to fix AC,oil leak and alternator. I also had to replace the transmission which gave out completely. Then about 14 months into owning this vehicle, the engine light came on, and I suddenly could not maintain speed. I was lucky I was not on the main highway where I would have been hit from cars behind me. KIA refuses to fix/replace the engine because it is out of warranty. I believe this is too many things that have gone wrong to not be considered defective. I now have to cut my losses and get a different car.
