2020 Kia Telluride

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.

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.

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.

We have had multiple issues with this car. First the pearl white peeling off on hood and above the windshield. Second CV3 axles boots leaking on our vehicle and multiple others at the Kia dealership. Third burnin oil even with good maintenance records. 3rd sunroof won’t open or close now for no reason at all. 4th back seat now attempts to fold at random times. Even with our kids in the seat. 5th oil housing leak. 6th CEL comes on and off randomly causing it to run rough. 7th screen is now to have issues of not working right. We’ve had to pay out of pocket for multiple things. Including the paint. We’ve spoken to service department and common issue they don’t see why it’s not a recall by now. Dealership is no help. Beware

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 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.

Vehicle manufacturers have certain basic rules and procedures that must be followed. When a vehicle manufacturer sells a vehicle, it has a duty to ensure that the vehicle functions properly and safely for its advertised use and is free from defects. When a vehicle manufacturer discovers a defect, it must explicitly disclose the defect and make it right or cease selling the vehicle. When a vehicle manufacturer provides a warranty, it must stand by that warranty. I believe Kia has breached its duties and rules as follows. Specifically, these Class Vehicles (Tellurides and Others) have malfunctions regarding their incorrectly manufactured piston oil rings which can result in engine damage and failure, and even potentially cause a fire known internally and secularly as an ("Oil Ring Defect”). Now, I purchased this car in January of 2023. Based on Kia’s active and persistent promotions touting the quality of its vehicles and my partners admiration of Kia vehicles, we considered Kia a quality company with a strong reputation for producing reliable vehicles. In addition to Kia's reputation through its marketing and promotion. We decided on the 2020 Kia Telluride because we believed it was a high-quality vehicle, after a salesman convinced us that the vehicle was highly reliable and came with great technological features. Since purchasing this vehicle it has only taken the vehicle to the certified dealership for its routine maintenance as recommended by both the vehicle alert system and the Service Department at Courtesy Kia. However, through all our consistent visits to dealerships, we had never been told of any recalls or defects related to his vehicle’s oil ring system. Since 2015, KIA has designed, manufactured, distributed, sold, and leased the Class Vehicles with this problem. As discussed earlier and in more detail below, the Class Vehicles contain a defect that causes a serious safety concern. The unresolved defect with the Telluride engine is an attack on owners.
