2020 Kia Telluride Engine

At approximately 94,000 miles, my 2020 Kia Telluride EX experienced a significant internal engine failure. The vehicle was properly maintained in accordance with the manufacturer’s recommended service schedule, including regular oil changes. A professional inspection required engine teardown. During inspection, the piston for Cylinder 6 was removed. The oil control ring was found to be stuck and would not move, with excessive carbon buildup present on the piston rings and piston crown. The cylinder walls and piston side skirts showed excessive scoring. According to the inspection findings, excessive carbon buildup caused the piston oil control rings to become stuck, allowing oil to bypass and resulting in damage to the cylinder walls. The inspector determined that the required repair is full engine replacement. This failure was not caused by misuse, neglect, or lack of maintenance. The vehicle has been inoperable and in the repair shop since approximately August 2025. An internal engine failure of this nature occurring under normal operating conditions raises concerns regarding engine durability and potential manufacturing or design defects that may affect other vehicles with the same engine configuration. Multiple owners of 2020 Kia Telluride vehicles have independently reported similar symptoms of excessive oil consumption, internal engine failures, and the need for major engine repairs or replacements at comparable mileages, some documented in NHTSA complaint records and owner forums. I am submitting this complaint to document a potential engine defect and to support investigation into similar failures.

My vehicle was consuming what I thought was a good bit of oil, I had an oils consumption test done, at 1000 miles it was 1 qt low, they said that is normal. So I drove away, another 1000 miles later my engine blew while I was driving, blowing metal everywhere! Left me sitting on the side of the road and Kia is saying it is not a known issue!! No lights car on indicating low oil or engine light.

My 2020 Kia Telluride has been serviced repeatedly for what has been described as an oil pan leak. My car has stalled out on multiple occasions and at one point wouldn't go above 60 on the highway. This is a know issue with 2020 Kia Tellurides, but the repair solutions are not solving the problem. My car stalled again and is idling rough and will now be serviced again for the same problem.

The vehicle is experiencing excessive oil consumption between oil changes, requiring frequent oil top-offs well before the manufacturer’s recommended service interval. No external oil leaks were identified when the vehicle had approximately 91,000 miles. At approximately 118,000 miles, the issue was identified during normal operation and routine maintenance, at which time potential engine-related concerns were noted. Excessive oil consumption raises concern for internal engine wear and the risk of sudden engine failure while driving, which could create a safety hazard. The vehicle has been taken to an authorized Kia dealership and is currently undergoing diagnostic evaluation, including oil consumption testing. At this time, the cause has not been fully determined. No warning lights were present prior to discovering the low oil level.

The argument for the warranty claim to be honored and the work to be completed is as follows. Kia Inc may not want to take responsibility for the engine. They may want to shy away from their duty by claim negligence on the part of the owner. Kia will ask the car owner to produce every receipt and service record you can scrape together just to prove that one was not done at an “authorized” center of some sort. Or they will argue the distance between intervals of oil change down to the smallest of detail to claim you abused the engine. An engine they know has a flaw. An engine with a ring flaw across multiple lines, years and models. That in multiple lawsuits they have in fact taken responsibility for and lost in cases so they are aware of the issue. But my argument is not necessarily these things. My argument is the oil warning light. That light is the real danger when combined with this fatal engine flaw. For a **3.8L V6 gasoline engine** (like that of the 2020 Kia Telluride) using **SAE 5W-30 motor oil**, you can theoretically determine the oil loss level that would trigger a warning indicator based on the overall oil capacity and typical safety standards. Oil Capacity and Warning Indicator Calculation Specifications of My 2020 Kia Telluride according to Anthropic AI. - **Oil Capacity**: 6.9 quarts - **Typical Safe Operating Level**: Generally, engines are designed to alert drivers when oil levels drop to about **1 quart** below the full capacity, which is critical to maintain proper lubrication. Oil Loss Threshold- - **Full Capacity**: 6.9 quarts - *Warning Threshold*: -*Safe Level*: 5.9 quarts (6.9 quarts - 1 quart)Safe Oil Level - The warning indicator would typically come on when the oil level falls to approximately **5.5 to 5.9 quarts.This range ensures the engine continues to operate safely without risking damage due to inadequate lubrication.Key Aspects of FMVSS 101 Regarding Oil Pressure Warning Lights.

EXCESS OIL CONSUMPTION

Oil consumption is excessive causing the vehicle to stall out, exhaust smoke and loose power. Upon several recommendations from the service shop, money has been dumped into repairs that has not resolved the issue. Now, I am adding oil every other week with no oil leaks. I am afraid I will keep dumping unnecessary money into this issue; however, I am more concerned I may eventually stall out on the interstate, highway, or unsafe area.

Car is burning over 2 quarts of oil every 1000 miles with no leaks, stalls at stop signs and lights. Engine needs to be recalled. No warning lights.

Cars burns over a quart of oil every 1000 miles. No oil light comes on on ever.

For some time, I was noticing that my 2020 Kia Telluride was consuming excessive amounts of motor oil - at least one quart per 1000 miles. I have had my car serviced regularly by a certified reputable mechanic and scheduled oil changes and other required service every 5000 miles. At around 69,100 miles the check engine light appeared and I immediately took the car in for service. I was advised that the spark plugs and valves were heavily carbon fouled. The spark plugs needed changing and the valves needed cleaning. It was also necessary to replace the coils. Total repair bill was $2008.84. I was advised by my mechanic that excessive oil consumption is a problem with KIA automobiles and after researching the issue myself, found this to be the case. Some engine design issues, most likely with oil leaking past the pistons into the combustion chambers, causing fouling. I have learned that ultimately, the pistons and valves will become fouled again, the engine warning light will reappear and possibly, the engine will break down - hopefully, not in a distant place without knowledgable service. The new car warranty for my KIA was 100,000 miles but since I bought it used (I am the second owner) the warranty was reduced to 60,000 miles. I filed a complaint with KIA Motors and asked that they simply extend my warranty to 100,000 miles but since there is no pending recalls for this problem, my request was denied.

Issue: Oil consumption/ low oil pressure indicator or check engine light did not go on. Was driving kids to school and on my way home I heard a loud rattling sound. Pulled over and had it towed. Shop said it didn't have oil, it was dry as a bone. We do regular oil changes every 5k miles and there are no oil leak spots on driveway or in garage. No oil light came on, no check engine light. Hoping this didn't damage my engine as I am at 110,000 miles.

Around Dec 13 the cooling fan started running by itself while the vehicle was in the garage for a few hours with the engine shut off, so, engine is cold.. What we do in this circumstance is starting and shutting the engine, that takes car of the situation until it happens again, sometimes right away or a few hours later or next day. I can't identify a relay that controls the fan. So, at this point we don't know how to resolve this problem.

On [XXX] , my wife heard a rattling noise while driving. I verified the rattling noise on [XXX]. On [XXX], I researched online and there are a lot of 2020 Telluride owners that experienced the same issue. They mentioned they had no oil in their cars. I checked the oil that morning and confirmed my wife's car had no oil. I reviewed the manual and checked the oil again according to the instructions in the manual. The car still registered no oil in the dip stick. The car did not report any warning lights. There was no engine light or oil pressure light that came on at any point in time to indicate there was no oil in the engine. Per the instructions in the manual, I drove the vehicle carefully to the auto part store. I purchased and added 6 quarts of synthetic blend 5W 30 oil. After that, the rattling in the engine seized. I sent a text message to Kia in Alpharetta, GA. I spoke with Izzy and explained the situation and requested an appointment to have an oil consumption test performed. She advised that the oil consumption test had a $440 cost and consisted of performing a series of oil changes over the course of a specified time to determine how much oil the vehicle was burning/consuming. She said I could call consumer affairs and I asked her if she was referring to Kia consumer affairs or the national/federal consumer affairs. She verified it was the national/federal consumer affairs and provided me with this number to call 1-888-327-4236 which actually belongs to Kia's consumer affairs hotline. Izzy advised that I had pending recalls in my car and asked why I have not brought the car in. I mentioned that I live in Ball Ground, GA and the nearest Kia dealership to me is the one in Woodstock, GA. However, I stopped taking my car there because I previously took the car there to get the oil changes done and each time I did the car would have a nail in one of the tires a couple days after the service. I lost confidence in the dealership. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

High oil consumption

I am consuming excessive oil consumption and the oil consumption tests have failed twice. This usually leads to driving and hearing noises and the car shaking which could lock up the engine and or cause a safety concern if locks up while driving and sudden stop.

The vehicle began burning oil around 61,000 miles, shortly after the 5-year/60,000-mile powertrain warranty period ended. The issue was confirmed by an independent mechanic, who identified leaking lower engine seals and excessive oil consumption. The mechanic advised that the engine will likely need replacement due to internal seal failure. This condition presents a potential safety risk if oil levels drop unexpectedly, leading to engine seizure or loss of power while driving. There were no dashboard warning lights or messages prior to discovering the problem; the only symptom was an oil smell and the dipstick reading consistently below normal levels between changes. The problem has been confirmed by an independent mechanic. The vehicle has been regularly maintained according to the manufacturer’s service schedule. The manufacturer has declined to offer assistance, citing warranty expiration and second-owner status, despite the failure occurring only 1,000 miles past coverage and appearing consistent with a latent manufacturing defect. The vehicle and documentation remain available for inspection upon request.

For a while now i have had to add extra oil about a quart every so often (didnt chart mileage )between oil changes and I thought its just burning some oil. Last few months it went up to adding 2 quarts and recently I had to add 3 quarts of oil and I had just checked it 2 weeks ago. There is never a light or any kind of notice on dash panel about low oil. I have a epiletic daughter that requires a safe vehicle to get her to the hospital. So this is a real safety concern. I have been reading this is problem with Tellurides. Because of the oil consumption problem tellurides have been stalling while driving. This could be a life threatening situation with my daughter not to mention for anyone driving the vehicle. The dealer will not do an oil consumption test since I'm at 113,000 miles. I paid $40,000.00 for a quailty vehicle. It should not have these kind of problems. KIA manufacurer said call the local dealer, so its just a run around Please help us figure this out.

Oil consumption- I have had to keep oil in the car to top off my oil in between oil changes. It will get low before I can make to another appointment and start shaking or making a loud noise when driving or braking. Oil consumption test says I’m burning 2 qt /1000 miles. Checking online and different forums this is a know issue for these models of vehicles

Vehicle engine is using 1-2 quarts of oil every month or so. Vehicle only has 85k miles. Engine also has a rattle/tick when accelerating. I believe this is due to the excessive oil usage.

Kia replaced oil filter adapter and now it burns through excessive amounts of oil. 3qts over 1000 miles. KIA wanted to do an oil consumption test but by the end it would have been out of warranty. Engine replacement would then not be covered.

Plastic oil filter housing cracked causing all oil to leak out. If not noticed would have blown engine while driving. Brought to dealership and not covered under warranty

My 2020 Kia Telluride consumes oil.at an alarming rate. About 2 quarts for every 1000 - 1500 miles. It currently has 125,000 miles.

History of engine randomly lurching/ hesitation when shifting. Have brought car in when it stalled out while driving, or at light. Largest problem now is oil leaking excessively. KIA has not been forthcoming on their history with this issue on 2020 Tellurides. Have been dealing with this the past couple of months and needed to bring it in for 'checks'. Service tech said that ½ Quart of low oil after 1000 miles was not enough for KIA to flag; told me to come in at oil change time. He said I did not need to worry as it was still covered under 100,000 warrantee. After checking it myself after driving another 1000 miles, I found that it was low. I brought this in for immediate concerns. I was told to 'wait' as my Service Tech was not there that day. He called me the next day to tell me I should bring in when I can so they can write up an 'approval ticket' for KIA. I brought in the following week. Again he was off. I spoke with another tech who told me it was low 2 ½ Q of oil - this was a week later. I now have to wait for KIA to 'approve'. I was told this could take a week or longer.. I need my car. I asked for a rental and was told I may have to pay for it. This is frustrating and disturbing. I am told by other tech that I will probably need a new engine and I should not drive my car until it is addressed. This car is 4 ½ years old and has less than 70k miles.

Vehicle burns oil, current mileage at 169k. User manual indicates 7500-10000 miles between changes, I am original owner. Dealership service set for 5k intervals since purchase and done on time. At 99k noticed noises from engine, light rattling but couldn't replicate and couldn't pinpoint at dealership service. At 112k noticed burning oil and rattling noises when accelerating from stop. Changed to 3k oil change intervals, began using premium fuel. 1quart of oil at 0-1000 miles from oil change (had a consumption test at dealership and confirmed "normal" at 112k), sub sequential mileage burns more than 1quart between 1k intervals, can easily burn through 4-5quarts between 3k oil changes. Oil smells slightly like gasoline closer to oil change time. Outside mechanic confirmed rattling as detonation. Concerns of oil not "burning" but mixing with fuel either through oil vapors getting through PCV valve and diluting fuel octane causing rattling. Knock sensor suppresses from causing engine damage, but still happens. Fuel may be getting into the oil, not sure how, but wouldn't explain detonation. No codes, no other issues. Only check engine light since rattling noticed at 99k was failing O2 bank 2 sensor which was replaced by licensed mechanic with OEM parts. The amount of additional oil maintenance and changes were not disclosed on expected maintenance costs sheet posted on vehicles, nor is it communicated in the users manual. Personal opinion is the additional maintenance between changes is unreasonable, and oil isn't "burning" but leaking into the combustion chamber.
