What 788 owners told NHTSA about the 2017 Kia Sorento Plug-in Hybrid

I was driving and heard a loud noise. The car started to hesitate and was making a knocking noise. I pulled over and had it towed where I was told it was a rod bearing failure and I needed a new engine. It had 130,000 miles. I have been reading online and found a lot of vehicles with the same engine as mine where this has happened and there are no recalls. Engines size 3.3L V6. Right now the car is sitting. I still owe on it and can’t afford to have it fixed. The oil was changed regularly. It was changed four weeks before this happened. No warnings.

I was driving our 2017 Kia Sorento 2.4 liter, on I-94 in Detroit, MI when suddenly, the vehicle would not go over 50 mph when the engine suddenly lost power on Friday 11/28/2025 ..We towed the vehicle to the Auto Repair Shop a few days later. On Tuesday 12/9/2025 the Auto Repair shop contacted us and said that their was plenty of oil in the vehicle but Cylinder 3 misfired and there is a loss of engine compression. Auto shop says cylinder 3 failed and now only 3 cylinders are now working on the 2017 Kia Sorento now mileage is now 94, 971 miles. I have not taken it to the dealer yet because even though there was a class action lawsuit, the Auto Repair shop has informed us, as well as other information online, that the dealer will sometimes try to avoid replacing the engine. I did contact the dealer on 12/10/2025 and informed that we do have maintenance records and have the vehicle towed there this weekend, however, my initial conversation with the Service rep did not sound promising to date.

To Whom It May Concern, I am the owner of a 2017 Kia Sorento (VIN ending in [XXX] ) and have recently experienced excessive oil consumption with the vehicle. The engine is losing approximately 2 quart of oil per 1000 miles, with no visible external leaks or exhaust smoke. I am aware that many Kia vehicles equipped with the 2.4L GDI engine have been affected by issues related to piston ring defects, which can cause abnormal oil consumption and, in some cases, premature engine failure. I also understand that Kia has issued recalls, service campaigns, and extended warranties on similar models and engines. I am requesting the following: 1.Confirmation of whether my vehicle is included in any recalls, service campaigns, or warranty extensions related to this issue. 2.A dealer inspection and oil consumption test to formally document the problem. 3.Information on any coverage, goodwill repairs, or warranty extensions available if my vehicle is determined to have this defect. I respectfully request your assistance to resolve this issue promptly. Please provide me with any relevant documentation or service campaign numbers in writing for my records. Thank you for your attention to this matter. I look forward to your timely response. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My 2017 Kia Sorento is experiencing significant engine issues, including excessive oil consumption and ongoing oil leaks. The Kia dealership initially told me I qualified for an oil-consumption test that could result in a free engine replacement if the results met the criteria. After inspecting the vehicle, they refused to perform the test because they said it was ‘leaking too much oil,’ charged me $600 for a gasket, but the vehicle still leaks and burns oil. Now the dealership claims the engine is not covered and wants $5,000 for a replacement, despite previously stating testing could qualify me for a free engine. This appears to be a common issue with Kia GDI engines and a safety concern due to risk of engine failure and fire. I believe Kia is improperly denying required testing and coverage, and I request NHTSA review this pattern. I included the invoice fr the gasket repair and pictures from the oil change I got last week showing pictures of it still leaking oil despite the repair at Kia.

I am reporting a serious defect involving my 2017 Kia Sorento 2.4 Liter GDI engine (VIN [XXX] ) At approximately 84000 miles, while still under the powertrain warranty, I brought the vehicle to the dealership from which I purchased it (Hutchinson Kia in Macon GA) due to engine hesitation and abnormal performance. I was initially told the engine might need replacement, but the dealer later claimed the issue was only a relay/software problem and performed a software update (likely the KSDS knock sensor update) At approximately 94000 miles, the engine suffered a SUDDEN CATASTROPHIC FAILURE while driving on the interstate, The failure was abrupt and created a dangerous situation in traffic. The Vehicle is now inoperable. The engine is equipped with the THETA II GDI engine, which has a documented history of bearing and connecting -rod failures, fires and sudden engine seizure. KIA is refusing to cover the failure, even though the symptoms began during warrantly and the KSDS update was reportedly completed. This appears to be consistent with the widespread THETA II engine safety defect previously investigated by NHTSA. The sudden failure of the engine posed a significant safety risk to myself, passengers and other motorists. I am requesting the NHTSA review the incident and evaluate whether KIA is properly honoring required safety-related engine replacements for Thet II GDI equipped vehicles. Thank You.

I am reporting a serious engine defect in my 2017 Kia Sorento. The has failed and presents an ongoing safety concern. The issue is while driving on the interstate, the vehicle began shaking violently, started making a knocking noise and the check engine illuminated. The RPMs also began spiking so I slowed down and got off at the next exit. Now every time I start the vehicle it continues to shake, knock and cannot accelerate properly -- the RPMs climb as high as 5000 with very little power. This is a clear safety hazard and makes the vehicle unsafe to operate on public roads.

Often, Service Managers like [XXX] from Kia University Dealerships will unlawfully charge you for diagnostic tests or other unrelated issues that should be free or try to persuade you to purchase repairs as a condition for completing the free recall work; however the repair is a standalone obligation, and the we should have the right to decline any additional, non-recall-related maintenance that the service department might recommend. Seven (7) months ago, I spoke with a Kia customer service agent that informed me that there may be another recall or another Product Improvement Campaign coming regarding my 2017 Kia Sorrento; therefore, please be on the lookout for issues with your vehicle and the engine. Therefore, when I took my vehicle to the Kia Dealership on University Drive “Which I had been going to since I purchased my vehicle” and informed them my engine light was just on, the gentlemen informed me that they needed to see the engine light on before they could input the Product Improvement Campaign/Recall. I ask the gentlemen why is this situation different, usually they just install the part and I just move out. Once again, I was informed they had to see the engine light on before they could install whatever they needed to install. Between the seven (7) months, I drove the vehicle to Kia and just before I got there, the engine light would go off, they still would not install whatever I was informed needed to be installed. I offered for them to take the vehicle and take it as long as you need to in order to get the engine light on, I was informed they did not have enough space in there shop. I started taken pictures that showed I was right around the corner from the shop; often three (3) minutes from the shop, they indicated they would have to emulate the engine light on before they could install whatever needed to be installed. Finally, after never pass seven (7) months, I was able to get the 2017 Kia Sorrento to the dealership and the first thing [XXX] info INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1) My vehicle incurred catastrophic engine failure. The engine stopped running suddenly. It does not crank over. It is available for inspection. It does not run. 2) I am thankful that no one was injured and that the vehicle did not catch fire. 3) There is a safety-related defect in certain 2017 Kia Sorento vehicles. 4) My vehicle was towed to the house and has not been inspected. 5) There were no signs of leaking oil or oil burning. No dashboard lights came on to signal overheating or low oil level. No check engine light ever appeared.

Engine burns oil excessively and Kia has this marked as a known issue. The oil is leaking inside the engine around the pistons and into the combustion chamber. Because the engine is direct injection, it now has to go through a combustion cleaning every time this happens at $700 a pop plus diagnostics which makes it over $900 every time this happens. Happens so often that it won't even get to the milage for an actual oil change to be due. Kia refuses to do anything until the connecting rod or connecting rod bearing fails and I have a complete engine failure. I feel like that is very dangerous and could cause serious harm to myself or others if I have an engine failure and cause an accident.

Prior to the below incident, my vehicle was driving normally. Oil levels were normal, and there were no warning lights. In June 2025, I was driving on [XXX] during morning rush hour. As I approached a traffic light at the end of this 3-lane expressway, the engine suddenly stalled. I rolled up to the red light. When safe to do so, I left the vehicle to stand on the side of the road so as not to get hit. I had the car towed to a local repair facility. Repair shop looked at the vehicle and determined that the engine was seized. They then checked for TSB's and discovered that Kia had, in some instances, extended the warranty to 180,000 miles and 15 years. My vehicle had 142,000 miles. I then had my car towed to the closest Kia dealer in Hickory, NC. The dealer initially indicated it was possible my car would be covered by the extended warranty, but they needed to run pressure tests to determine the cause of the engine seizure. Over the next 2 weeks, I called the dealer repeatedly, but they had no update for me. After about 2 weeks, they told me that my vehicle would not be covered by the extended warranty, and a new engine would cost me $15,000. I then called Kia Customer Care, and the representative told me there was nothing they could do. I asked about an appeals process and was told there is none. After I returned from vacation in early August, the Kia dealer contacted me and requested that I pick up my vehicle. I drove to the dealer and called a tow truck to bring it to my home. I rented cars at my own expense from the time of the engine failure until I bought a new car in mid-August. Shortly thereafter, I arranged to sell the Kia to a used car dealer for $1,500, far less than I would have received with a healthy engine. At that point, I needed to get the car out of my garage. While cleaning out the car the night before it was to be picked up, I opened the hood and found that the engine had been left disassembled with parts lying all over the place.

I came to this website because it was suggested to me to look for a recall. While there is an active recall with my car, the interesting part to me is the fact that the issues I'm having with my car match a recall for the same model as mine, just a different spec. To me that seems odd, I'd have the same type issues... I was wondering how to get this examined.

On July 25th when I started my car , 2017 Kia Sorento, to leave work, it made a horrible knocking noise when it was starting, but once it started the noise stopped, no alert lights came on, so I drove it home 7 miles and parked it for the weekend. When my husband and I took it out again on Monday, July 28th, we had driven under 10 miles and gotten up to 70 miles an hour on the toll/express road, the check engine light started flashing as the power produced by the engine drastically declined and acceleration seemed capped or limited. We were able to safely exit the toll road without causing or being involved in an accident. We drove it 6 more miles home and parked it. A week later we had it toed to a Kia mechanic who confirmed that the engine had been using oil, had metal shavings in the oil and the rod bearing had failed. The engine would have to be replaced. Once the engine was replaced, it was determined that the turbo had also failed on the impeller side and would have to be replaced. We did not take it to a dealer. We had both components replaced by a Kia mechanic at our own cost.

It’s been a month since I did an oil change. However, while I was driving the car, I heard a noise like the engine had no oil in it. I stopped and after 15 minutes I checked the engine for oil when I discovered that the engine was empty. I then checked for a leak and there is no leak detected. I took it to a Valvoline to get an oil change. This is when I discovered that the engine is burning the oil. This is most likely to happen due to a manufacturing problem. I am submitting this complaint and would like to have an investigation done on that matter because it is a safety concern when a car keeps burning oil without any leak detection.

Engine seized with zero warning lights, cautions, check engine lights, or low/high indicators. It started knocking and was driven 3 miles to our mechanic who said it was a failed engine. I called the Kia dealer who recommended I tow or drive it to the dealer. ~3 miles from our house, less than a mile from the dealer the car lost all power. We had it towed. The service manager chastised me for not towing but also told me irregardless of how it arrived that the engine was no longer functional. It is out of warranty w/ 143,000 miles but without any indication of a problem how was I supposed to mitigate any risk. From the start of the knocking until the engine failed it was less than 6 miles. The mechanic had to put 3 quarts of oil in the car and it still failed on the way to the dealer. I get regular oil changes and have never been told it’s running low on oil. I’m asking that somebody please look into this issue. Thank you. R/ Aaron

This 2017 Kia Sorento with the 3.3L V6 Lambda II engine appears to have had possible rod bearing failure or connecting rod failure. This vehicle has 107,987 miles on it when the incident happened. 2 hours into a drive on the highway, the car began to sound like it had a possible exhaust leak, however this was followed shorty by knocking which prompted us to pull over and just as we made the shoulder as the engine quit and began to smoke heavily. Went to quickly open the hood and the smoke died down in about a minute. Most likely due to the oil hitting the exhaust from the hole the rod left in the block. There were no oil lights or other indications that anything was going to happen prior to this. The vehicle has been maintained meticulously with all maintenance items. This vehicle is available for inspection. Let me know if this needs to happen prior to KIA getting ahold of it. Our entire family was in the car (5 people including our dog) and we were at highway speeds when this happened. Fortunately we were able to get over just before the engine blew. Also fortunate enough to open the hood fast enough to get it cool before it started a fire. We are going to take it to the dealer for inspection, however both the dealership and Kia Customer Care said this is not currently under any warranty for engine failure. I have yet to inspect myself to take pictures from under the car, so no inspection has been thoroughly performed. As previously stated, there was no warning lights, the car did sound like it started to have an exhaust leak no more than a minute or two before the knocking started.

On 8/16/2025 my 2017 Kia Sorento experienced major engine failure which resulted in loss of power and severe engine misfiring. I submitted a warranty claim with full maintenance documentation to Kia cooperation but was denied coverage on 8/27/2025. This denial is improper because 1.The engine type is covered under recalls and/or the Kia Engine Class Action Settlement, which extends coverage to 15 years / 150,000 miles and my vehicle currently has 94423. 2.I complied with all maintenance requirements and have already provided numerous records. 3.Engine failure presents a serious safety hazard and has been widely reported.
