My 2020 Kia Telluride experienced progressive and severe engine oil consumption that ultimately required a full engine replacement. Beginning well before the failure, the vehicle required frequent manual oil top-offs between scheduled changes, including on longer trips. No low-oil warning light, check-engine light, or oil-pressure warning ever illuminated to alert of critically low oil levels. In late March 2026 an independent service center replaced the engine oil filter housing and related gasket after an oil leak was observed; an axle damaged by oil spray was also replaced at that time. Shortly afterward the manufacturer issued a warranty extension covering oil-filter-housing gasket leaks on 2020–2025 Tellurides, extending coverage to 15 years/180,000 miles for that specific condition. Despite the housing/gasket repair, the excessive oil consumption continued. Several weeks later the vehicle lost power and broke down while being driven. It was towed to an authorized Kia dealership. Technicians inspected the vehicle, confirmed heavy oil consumption (noting the engine had been requiring large amounts of oil nearly weekly with no external ground leaks observed), and diagnosed catastrophic internal engine damage. They recommended complete engine replacement at a quoted cost exceeding $13,000. The dealership also inspected the oil-filter housing area under the recent warranty extension but determined the engine damage itself fell outside that limited coverage. The oil-consumption problem and resulting engine failure create a clear safety risk: sudden loss of power or stalling can occur without any dashboard warning, potentially while the vehicle is in motion on public roads. The failed engine and related components remain available for inspection. The condition has been confirmed by both an independent service center and an authorized Kia dealership. Similar oil-consumption and engine-damage reports have been widely noted among other owners of the same model.

I purchased my 2021 Kia Telluride S new, with only 22 miles from the test drive. XXX (approx. 53,000 miles, vehicle age 18 months): The transmission failed while I was traveling approx. 75-80 mph on a major highway in [XXX]. Upon failure, the vehicle suddenly lurched as if the brakes had locked or the parking brake had been applied, nearly causing us to strike our heads on the dashboard and creating a hazardous situation for other traffic. After the failure, the vehicle would only operate in approx. first through third gears and reverse, and would not exceed 25 mph. We were forced to limp the vehicle off a busy six-lane highway. XXX: Due to parts delays, the vehicle was not returned until November 2022 after the transmission work. XXX (approx. four months later): The vehicle developed engine knock and excessive oil consumption. Advised this may have been related to oil degradation while the vehicle sat waiting for parts. Since then, I had to regularly check and add oil between oil changes. Despite low oil levels, no oil pressure warning light ever appeared. XXX (exact date unknown): While opening the sunroof at a stop, a loud crack occurred and pieces of the sunroof track, plastic and metal, fell onto me and my passenger. The glass is intact but became partially stuck open without the track to guide it. XXX: The engine knock worsened and became a squeal while driving approx. 60 mph. The vehicle lost power, requiring me to turn on hazards and coast off to avoid accident. Dealership mechanic advised that the engine had thrown a rod and blown the oil filter housing gasket. The vehicle is currently at the dealership and available for inspection. Kia has denied coverage despite the failure of a component linked to excessive oil loss and a recently extended 180,000-mile warranty, even after the engine threw a rod following a sudden loss of oil pressure. The failed transmission has likely already been disposed of. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Loss of oil that is going out the heads and exhaust. This causes loss of power. Oil light doesn’t come on. This happened twice. Once in March and we took it to the dealership to have it fixed. Unfortunately, the issue wasn’t fixed and it happened again in August.

My 2021 Kia Telluride has developed progressively worsening engine problems without any warning lights ever appearing that may present a serious safety concern. Approximately two months ago, the vehicle began experiencing significant engine shaking and rocking. Maintenance and repairs were performed, and the symptoms temporarily improved. The engine symptoms later returned. The vehicle began making a noticeable ticking noise that progressively became much louder and occurred both while idling and during acceleration. The vehicle subsequently shut off after being driven to an independent mechanic. Multiple warning/diagnostic alerts appeared, and the vehicle would not remain running when restarted. The mechanic checked the engine oil and found it essentially empty. Approximately 4½ quarts of oil were added. The ticking noise continued despite the addition of oil. Later that same day, the engine developed a pronounced knocking noise that continued while driving. There was also a hot smell, and I had noticed discolored smoke coming from the exhaust. The vehicle is currently parked and is available for inspection. I have stopped driving it because I am concerned about an engine failure and the possibility of the vehicle shutting off or losing power while being operated. The vehicle has been maintained and I have documentation of its maintenance and repair history. The underlying cause of the severe oil loss and engine symptoms has not been determined.

I am reporting a safety concern involving my 2022 Kia Telluride EX with approximately 95,000 miles. The vehicle has experienced intermittent rough running, significant loss of engine power, stalling, and recurring check-engine warnings. During one incident, the vehicle started, sputtered, and shut off. The engine oil level was found to be extremely low despite the vehicle having received an oil change approximately 2,000 miles earlier. After adding approximately one quart of oil, the vehicle was able to start and remain running. The check-engine light subsequently illuminated and Kia Connect reported diagnostic code P000A00. The warning light has intermittently turned off, but the fault remained stored in the vehicle's computer and was later confirmed by a Kia dealership. I brought the vehicle to an authorized Kia dealership because of the oil loss and drivability concerns. The dealership documented that no external oil leak was found and stated that the engine was likely consuming excessive oil. An oil-consumption test was initiated. According to the dealership's subsequent documentation, after approximately 1,000 miles the engine was more than two quarts low on oil. During this process, the vehicle continued to experience drivability concerns including rough running/stalling and poor engine power. I am concerned that the vehicle may stall or experience significant loss of motive power while being driven in traffic. I routinely use this vehicle for commuting and transporting my family. Kia ultimately declined warranty coverage based on insufficient maintenance documentation. I am not submitting this complaint to dispute the warranty decision. I am reporting the underlying safety concern because the vehicle has experienced stalling/loss of power together with substantial engine-oil consumption, and the underlying mechanical cause has not been clearly resolved.

2025 Kia Telluride, rental vehicle, 29,450 miles at failure. Driving XXX W toward the [XXX] exit with my wife and two children (ages [XXX] and [XXX]), the cluster lit with simultaneous failures: electric power steering, electronic parking brake, ABS, stability control disabled, tire pressure monitoring, forward collision-avoidance, lane keeping, master warning. I photographed it. Nothing about how the vehicle drove had changed. At highway speed traveling straight, steering effort felt normal. There was no progressive degradation and no warning I could feel. I noticed a slight difference changing lanes for the exit. On the ramp itself, a banked turn taken at speed, the wheel required extreme force to turn. The loss of assist was undetectable until significant steering input was actually required, which happened mid-maneuver on an interstate ramp. I am a large, physically strong adult and forced the wheel through the turn. I do not believe a smaller, older, or weaker driver could have completed it, and a crash at that interchange seems a likely outcome for many drivers. Stopping on an interstate shoulder with two young children seemed more dangerous than continuing two miles to the airport exit, so I continued, with ABS and stability control also inoperative. The vehicle developed harsh, jerky shifting and audible clunking. In the rental return lot the wheel would not turn far enough to complete a tight turn. I shifted to reverse; the vehicle did not move, then shut down completely and would not restart. With the vehicle dead the front doors opened, but the rear doors and liftgate would not, and the windows were inoperable. My children were confined inside roughly 10-15 minutes at 86F until an employee climbed in from the front and released the rear doors from inside. The inability to open rear doors or the liftgate from outside after a total power loss is a serious defect in its own right.

System/Component Malfunction & Availability: The vehicle's electronic safety and engine control systems malfunctioned while driving at speed. This issue has occurred twice under identical thermal conditions, with the first instance occurring on 5/19/26. The vehicle is fully intact and available for inspection upon request. Safety Risk: During the first incident, a false dashboard warning triggered, but the physical engine remained running. However, during the most recent incident on 7/2/26, the defect escalated and the engine physically stalled while driving on the road in high 90-degree ambient temperatures. The stall caused an immediate loss of power and a complete loss of power steering assist, making the vehicle incredibly difficult to control and creating an imminent risk of a crash for my family and surrounding drivers. Dealer Confirmation & Inspection: Following the first incident, the vehicle was brought to a certified Kia dealership and left in their custody for 10 days for diagnostic troubleshooting. The service center stated they could not pull a hard diagnostic trouble code (DTC) and could not replicate the failure on a standard test drive. No other entities (police, insurance) have inspected the vehicle yet. Corporate Kia was notified (Case #26160914) but refused to authorize a specialized repair plan because the dealer could not replicate the issue. Warning Symptoms & Messages: There were no mechanical or performance warning symptoms prior to either failure. Both times, the issue began instantly with an audible cabin alarm and a prominent dashboard display message stating: "Engine Off! Shift to P or N, then start engine." During the first incident, the physical engine remained running despite the message, allowing us to safely pull over and reset the vehicle by cycling the ignition. During the second incident, under the same extreme outside heat (high 90s), the engine completely cut out mechanically, creating a severe stalling hazard.

the federal safety agency Vehicle Safety Complaint – 2021 Kia Telluride - VIN: [XXX] I am filing a safety complaint regarding my 2021 Kia Telluride. I purchased the vehicle on XXX, with approximately 124,000 miles. An oil and filter change was performed shortly before the sale. After about 2,000 miles/126K, the vehicle suddenly lost power and stopped. It was towed to a repair shop, where technicians found the engine oil level was extremely low or empty, despite no low-oil warning light appearing. The oil was serviced, and the vehicle was returned to operation. About 3,000/129K miles later, the vehicle again lost power and stopped in Ardmore TX. It was road side mobile mechanic found little to no oil and he refill the oil. After 100 miles/129.1K again same problem engine stopped and no oil. was towed to the same shop, where technicians found little to no oil and diagnosed severe engine damage requiring engine replacement. Mechanic informed there was no oil leak from the engine however, excessive oil burning in engine causing this issue. My concern is safety. On all three occasions, the vehicle lost power on the freeway at night while my family with two kids was in the vehicle. I believe excessive oil consumption and the lack of a warning before engine failure may represent a safety defect. I request that the federal safety agency investigate this issue and require Kia to review the vehicle’s engine design and warning systems.
