1.Component/System Failure: The issue involves a recurring failure of the oil pressure switch, which is part of the engine-??s lubrication monitoring system. This malfunction has resulted in an oil leak that subsequently damaged a major wiring control harness and the associated control module. The affected components are available for inspection by an authorized service center. 2.Safety Risk: The oil leak poses a safety risk by potentially compromising the vehicle-??s engine performance and electrical system integrity. While there has been no direct incident of injury, the malfunction increases the risk of unexpected vehicle failure, which could endanger the driver and others on the road. 3.Confirmation of the Problem: The recurring issue was initially diagnosed by an authorized dealer. After the first repair under warranty, the same problem reappeared, and an independent service center later confirmed that the oil pressure switch was leaking excessively. This repeated diagnosis supports the conclusion that the component is defective. 4.Inspections Conducted: The vehicle has been inspected by both the authorized dealer and an independent service center. Additionally, the previous repair under warranty was conducted with oversight from manufacturer representatives. There has been no involvement of the police or insurance representatives regarding this incident. 5.Warning Lamps or Symptoms: There were no specific warning lamps or error messages that appeared before the failure. The primary symptoms noted were poor acceleration and unusual engine noise, which first appeared shortly before the issue was identified as an oil leak.

[XXX] the engine on my 2017 Kia Sorento seized up due to severe oil leak. There was a recall earlier in the year for oil pressure gauge which I had replaced. This seems to be a common problem in Kias as there is the class action law suit for this very problem however my car does not qualify but after reading many forums this is still a common problem in Kias that are not covered in this class action. I am now left with an inoperable car and nothing to show for it. I have been in touch with Kia Corporate with no help, lawyer, Office of Attorney General and MyCarVoice.com. Hoping you all can add some advice or answers. Thank you. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Urgent Assistance Needed: Engine Issue and Warranty Dispute Since September last year, the engine warning light has been consistently on. Whenever I took the car to the Kia dealership, they merely mentioned that the system was -??too rich-?? and assured me it was not a concern. Instead of addressing the engine issue, they recommended replacing unrelated parts such as the air filter. When I took the vehicle to a local mechanic, I was informed that the engine was not in good condition, causing the oil to burn quickly, which indicated an engine problem. However, the Kia dealership did not acknowledge this issue. On February 7th, while driving, the vehicle began shaking violently and making unusual noises. I immediately brought it to the local mechanic, who diagnosed that the #4 cylinder valve was burnt. The following day, on February 8th, I brought the car to the dealership. They mentioned that the engine might need to be replaced and promised to contact the warranty company for approval. They initially seemed optimistic, suggesting that the replacement could be covered under the warranty. However, two weeks later, I received a response stating that the warranty would not cover the repair. Despite multiple attempts to contact Kia headquarters via email, I have not received any response. Upon further investigation, I discovered that my vehicle is part of the Theta II engine recall. Kia had publicly announced a lifetime engine warranty for vehicles with this issue. However, now that my engine has failed and requires replacement, they are refusing to honor this promise. The estimated cost for the engine replacement is $8,000, and I have been told that I am responsible for the full amount. I kindly request your immediate assistance in resolving this issue. I believe Kia should honor its commitment to the lifetime engine warranty for the Theta II engine vehicles. Thank you for your prompt attention to this matter. I look forward to your response.

While on vacation the oil light came on (just had it in for maintenance, told them it was using oil but no sign of leak, they told me it was fine to go on vacation, that there was no problem) we put oil in but then engine light came on. It was Saturday night and warranty co. had no emergency phone number. Got to Hotel, Monday was towed to Repair Shop was told after they inspected the car that we had to replace the engine. Warranty Co. replaced the engine a MONTH later with a used engine. My car was not on the recall and should of been. KIA did not answer any calls or emails. Also I am still paying for it. I had a lo of problems with the warranty co, luckily I kept up with the maintenance on it, because if I did not they would never replaced the engine, but now I have to worry about it happening again. Also my car is in Arkansas and we live in Wisconsin.

My vehicle started leaking oil from the engine from an unknown location. I took it to the dealership for them to diagnose the cause of the leak which is under warranty. The dealer refused and did not honor the warranty. Now my car is immobile

While driving the check engine light came on. I could feel the vehicle losing power despite giving it gas & seeing the rpm's rise. While looking at the dash board to see if there any other indicators the check engine light started flashing followed up by the oil light and another light (can't remember what it was). I pulled off the highway and the vehicle was shaking while running before cutting out. It would not restart and I had it towed to the dealership. The dealership attempted to diagnos however all they can tell me is cylinders 1 & 3 will not hold compression, the engine needs to be replaced & despite only having 82K miles it's not covered by Kia. The vehicle has been meticulously maintained at the dealership.

Vehicle up to date on oil changes. Driving down interstate and vehicle just stopped without warning. Message to contact a dealer popped up. When diagnostic put on vehicle shows camshaft and crankshaft bad. No oil on dipstick AT ALL. Oil light never came on showing low. Never seen oil in garage so no leaks. Sensors showing misfire were changed along with spark plugs and coil packs. Codes never cleared. Car is not drivable but has been well maintained and up to date on everything. After researching I have seen multiple pages and pages of the same exact complaint on same exact vehicle. There is a recall for certain 2017 kia Sorento 3.3L V6 engines but shows mine is not affected although my vehicle is the exact same as the recall and having exact same issue as the recall. I would like this looked into and a explanation for the engine issue with help on fixing it through Kia. This is a good vehicle never gave ANY issues at all, nor gave any warnings on the issue that caused it to stop running.

like many other kia owners I have a Kia Sorrento and after 6700 miles started running into problems with oil consumption. I have Toyota extended warranty because I am second owner and wanted some type of coverage. Kia knows there are problems and giving customers run around plus higher insurance premiums. second time over 5 days my car is being evaluated I have done 3 oil changes since March 2024 I did get engine oil switch fixed did own oil consumption test which Toyota did not except because it was not Toyota or kia dealer that did it. I would sue them on my own or geta new car if i could afford it. I love the car for size and smoothness of ride but they are failing their customers.

Engine Oil Burning 2-4 quarts of oil in less 1000 miles.

I have noticed that there is some il leavking from the car. My independent mechanic was sevivign the vehicle and has informed me that the head gasket has a leak and that this is a common problem with Kia Sorento 3.3 from 2017. I have taken to a kia dealer and they onfromed that there was only a leak from the oil pan which is not possible as i have seen the leak coming from higher up the engine. I have informed Kia USA and they have deferred to the warranty that i purchased. The small print thati was not made aware of was such that buying the vehcile used the manufacturere was only liable for the first 65,000 miles. I purchase an extended warranty and power train and engine were not covered. As such I am lookign at some point to a failing engine or a bill for 3 to 4k. Kia know of this issue and have done nothing to put this right before the issue happens

I was driving down the road and my car shut off. It would not restart at all. I just had my state inspection and a new oil change on November 11. There was no light on the dash at all. They had to tow it to kia where it has been since the 25th.

I have been having excessive oil burning for months. When I took it to the Kia dealer, this was a known issue. They told me I'd need to continue to regularly top off my oil (way over the recommended amount) or risk my engine blowing. Just over the warranty at 102,114 miles the car seized. The repair shop diagnosed it as a valve/cylinder head issue, but the engine has not been working as it should since long before before the 100,000 warranty mark. It is documented at my Kia service center. My car is useless, not even drivable now. This is a known issue (the burning of oil) and Kia isn't upfront about this issue. While there was a class action lawsuit for other engine issues in this model, there is no accountability for the issues we face. My car is worthless and at only 102k miles. I've taken great care of this vehicle, but it is poorly made. [XXX] lists 339 complaints about the 2017 Sorento's engine, with engine failure being the most significant issue. I feel I was taken advantage of by trusting Kia that this was a solid investment. The cost of repair is $5,000-10,000 depending on if the 5k does the job - it was suggested that the repair doesn't always work without a full engine rebuild.

Driving down the interstate to pick my children up from school and all of a sudden the car made a weird bubbly grinding sound and stopped accelerating. I had to pull off and park as the car would not go any further. My vehicle has had regular maintenance and oil changes since I purchased it. I had in fact just put a full quart of oil in it. The first mechanic stated that there was metal shards in the oil. In between oil changes, I have to add several quarts of oil because it seems to just disappear. There-??s no oil leak yet the oil would be almost completely gone not even a full month after a complete oil change. My car has currently been sitting at the Kia dealership for a lot now waiting for repair. I paid for the extended warranty yet. Kia is dragging their feet and won-??t even offer me a rental car while I wait for my car to be repaired, no one returned my calls. No one updates me on what-??s going on. I am fed up.

While driving my vehicle going up a hill, I all of a sudden had a loss of power and heard a bunch of noise. I had to pull over as well as possible while people were speeding past because the noise turned out to be a piston rod blew apart causing catastrophic engine failure

- Northern Cambria, PA, USA

Heard light knocking coming from engine compartment while on a trip. The knocking become louder while driving home on County Roads. Knocking was very loud when I reached a populated area. While attempting to get to an auto store the vehicle drove very slowly and then a huge plume of black smoke discharged from the rear and front of the vehicle. The car stopped on an entrance ramp and would not start again. I had the vehicle tow on a flat bed tow truck to a vehicle repair shop in our hometown. This was on a Tuesday after normal business hours. The following morning I took the key to the shop and explained what happened. The shop called me later the same day and told me the engine was blown and not salvageable that there was a hole in the engine. I am in the process of looking for a new car due to the unreliability of installing a rebuilt engine. There have been several documented cases of KIA engine failures. I do not know if this has been reported, but I would like a record of this failure reported and documented. Thank you.
