2021 Kia Telluride

The 3.8L Lambda II GDI V6 engine suffered catastrophic failure at approximately 102,000 miles. The root cause is excessive oil consumption documented by an independent repair shop well before the 100,000-mile powertrain warranty expired. At 81,207 miles, during a routine oil change, the mechanic checked oil level before draining and found nothing on the dipstick. Only about 3 quarts drained from an engine with 6.9-quart capacity, meaning nearly 4 quarts were consumed since the last change. This finding repeated at 88,408 miles, with the shop documenting it was the second time oil was critically low. Both events occurred within the powertrain warranty. Original invoices are available for inspection. At no point during ownership did the vehicle display any warning — no low oil level indicator, no low oil pressure warning, no check engine light — despite oil levels falling dangerously low on multiple documented occasions. The absence of any driver alert while the engine operated with less than half its required oil is a serious safety deficiency. The engine failed on while driving with passengers including three young children, causing complete loss of power and requiring an emergency pullover. Loss of engine power at speed creates serious crash risk. The vehicle was serviced at an authorized Kia dealer at 60,449 miles where a 60K service, multi-point inspection, and recall SC243B were performed. The dealer made no mention of oil consumption, did not reference TSB ENG222 (addressing excessive consumption across multiple Kia engine families), and did not perform an oil consumption test. Kia Consumer Affairs refused to submit a goodwill claim and closed the case, citing incomplete oil change documentation — despite the defect being documented within warranty. Excessive oil consumption in 2020-2021 Tellurides appears systemic based on numerous owner reports describing the identical pattern: extreme consumption, no dashboard warnings, and eventual engine failure.

This car keeps burning excessive oil. I am on my 3rd oil consumption test each time it burns 0.75q in 1000 miles. The dealer states that that is not enough oil. My mile 3000, there is no longer oil on the dip stick, and we start the process all over again. This car has been burning oil that doesn’t even meet a standard oil changer interval since the cars had 70,000 miles on it. It now has 94k. After reading multiple online forums, it seems like anyone who has a 2020-2021 Kia telluride has this problem, and Kia refuses to acknowledge the his problem.

2021 Kia Telluride experienced sudden engine failure at approximately 120,000 miles. The failure occurred without any prior warning. There were no oil warning lights, dashboard alerts, or other indicators of low oil or engine malfunction before the engine failed. After inspection, the mechanic found no oil on the dipstick and discovered metal flakes in the engine and oil filter, indicating severe internal engine damage. No external oil leaks were identified that would explain the loss of oil. This suggests a potential internal engine defect or abnormal oil consumption without warning to the driver. The vehicle has been regularly serviced and properly maintained according to recommended maintenance schedules. There was no neglect, missed oil changes, or failure to maintain the vehicle. This sudden and unexpected engine failure creates a serious safety concern. A loss of engine power while driving, especially at highway speeds or in traffic, could significantly increase the risk of a crash and place the driver, passengers, and other motorists at risk.

Cooling fans running continuously after the car is turned off, which drains the battery. The dealership has identified that this is due to a faulty fan relay that will need to be completely replaced. The battery has been replaced once and the issue continued indicating that it was not a battery issue. The car ran out of battery in a busy location and caused risk to the passengers that were then exposed to busy traffic. The car has been inspected by repair specialists at the Vaden Hyundai Service Center. There were no warning lamps, messages or other symptoms before the problem began.

After owning this Telluride for a year the engine started stalling. I took it into the nearest Oil change company, and they informed me that the oil was completely out and dry. I always stay up to date with my oil changes, so this was a huge shock. There was no light that ever came on stating an oil concern and there was no light that came on even when the engine stalled. This company sent me directly to Kia stating they have seen this several times with this vehicle and they have oil consumption issues. I went to Kia and they had me do the oil consumption test. When completed they stated I was within the "standard" oil consumption levels. I asked why the car didn't even have an oil light or engine light come on as a warning and they had no answers for me. Had a light come on I would've taken it to be looked at prior to having the engine stall on me which was a major safety issue. Fast forward, I ended up and purchased another car and gave the Telluride to my husband. I drive a lot for work and he doesn't, so it made more sense to help with the oil. We are now having to put at least 3 quarts of oil in it in between oil changes. And he has still experienced the engine puttering. Both times with our kids in the car, steering becomes difficult and he has to pull off the road. Once he turns it off and restarts, it seems to be fine. Another mechanic told us that they anticipate a recall to come out with the 2021 Telluride soon since they have already recalled previous years for the same issues. It is absurd to have to put in 3 quarts of oil in between oil changes. The fact that no warning lights have ever come on is safety concern. The car randomly stalling is a safety concern. Kia needs to do something about this before someone gets injured.

Component/System Failure: The engine and lubrication system appear to be malfunctioning. The vehicle has repeatedly experienced sudden engine shutdown while stopped at traffic lights and during low-speed operation. The dealership has identified oil leakage involving the oil pan and oil filter housing and has indicated there may be an internal oil leak within the engine. The vehicle is available for inspection upon request. Safety Risk: When the engine shuts off unexpectedly, the vehicle loses propulsion in active traffic. This creates a risk of rear-end collision and prevents immediate maneuvering out of traffic flow. The loss of engine power while stopped or moving at low speeds presents a serious safety hazard to myself and surrounding drivers. I am concerned that the suspected internal oil issue may lead to catastrophic engine failure while driving. Dealer Confirmation / Reproduction: The issue has been reported to the dealership multiple times beginning in January 2025. The vehicle has undergone multiple inspections and repair attempts, including partial fuel injector replacement, battery replacement, and an oil consumption test. The dealership has acknowledged oil leakage and has stated that replacing the oil pan gasket and oil filter housing may not resolve the suspected internal oil leak. The defect has not been permanently corrected. Inspection by Manufacturer or Others: The vehicle has been inspected multiple times by the dealership. The matter has been escalated to Kia Corporate for review. No police or insurance inspections have occurred, as no collision has yet resulted from the stalling events. Warning Lamps / Symptoms: During each stall event, the check engine light illuminates along with multiple dashboard warning lights. The stalling first began in January 2025. Oil-related concerns and possible oil loss were reported during prior service visits. The condition continues despite repair attempts.

On 12/24/25 the vehicle experienced the very same issue, on the highway, with my family in the car, coming from Christmas Eve festivities. The car decelerated and NO cel (check engine light) ever came on. when transporting to dealer, the car began rough idling like it wanted to die, but still no CEL. At this time, I am told there is a need for a new engine but no supporting documents or other diagnostic documentation has been shared with me and KIA at this time is refusing to resolve the issue under the powertrain warranty and the car is still under 80k miles (powertrain is until 100k) Additional Info: on Aug 5, 2025, the vehicle, with no warning lights or CEL present, the vehicle decelerated on the highway, putting me and my family in imminent danger (large truck behind us who narrowly missed hitting us) and after about 10 min the CEL came on. the vehicle would not drive above 45mph. Once the car was stopped, the CEL went off and the vehicle was diagnosed as failed high-pressure fuel pump, OCV harness, and solenoid, along with accompanying lines/gaskets/plugs and seals. After the repairs were done, I reported rattling noise to the dealer within 5 days of picking up the vehicle, when I had to bring it in for an axle joint replacement (aprox 8/12/25).

The checked engine light came on with Code: P219C00. Vehicle was taken to the Kia Perris dealership for maintenance inspection. This happened after the vehicle had to be taken back to dealership for an oil leak post oil change service. The issue has been reported by multiple owners on Reddit. Seems like a manufacturer issue that should be addressed.
