2020 Kia Telluride

My 2020 Kia Telluride EX experienced a sudden engine shutoff / loss of motive power while driving in traffic. The vehicle stopped in the roadway, would not immediately restart, and restarted later after sitting. This was not normal stop/start operation, the car shut down. No low-oil warning appeared before the event. I am also aware of multiple similar owner reports online describing high oil consumption, stalling, and lack of warning in 2020 Tellurides, but this complaint is based on my own direct experience and concern. It was scary and life threatening!

2020 KIA Telluride failed oil consumption test. Available for inspection upon request. A vehicle running on no oil will cause an engine to seize putting myself and others at risk. Confirmed problem by KIA. I have documentation of 3 oil consumption tests performed on my 2020 KIA Telluride at the dealership. Inspected at dealership by service department. No warning light to indicate low oil or to check engine. Stuttering and stalling of vehicle at stops caused me to bring in the car to KIA.

Engine has a Pcv valve issue that causes oil to leak from seals and burnt through the pistons causing loss of oil, engine damage and possible engine failure while driving. This could cause vehicle to lock up and possible cause an accident especially at freeway speeds. There is no low oil indicator or check engine light that comes on to let driver know that the oil is low

Engine oil is disappearing in my 2020 Kia Telluride. This has been occurring for an extended period of time ( Since 2020) Early on, I was not driving frequently and did not immediately recognize the severity of the issue. However, about a year ago, when my work required significantly more driving, I began noticing that a large amount of oil was missing between checks, at times approximately half of the engine’s oil capacity. I initially suspected the plastic oil filter housing, which can crack or leak if it is over torqued during oil changes. To address that potential issue, I purchased an aluminum oil filter housing and had it installed. While that repair resolved one concern, it did not stop the ongoing oil loss. At times, when I check the dipstick, there is little to no oil registering, indicating the engine is operating on residual oil. When I remove the oil filler cap, smoke is visible coming from the opening. There are no signs of external leakage, no oil on the ground, and no oil leaking under the engine. This strongly suggests the engine is consuming oil internally. This is a serious safety concern. If the oil level drops unexpectedly while driving, the engine can suffer sudden damage, lose power, stall, or fail without warning. Because I regularly travel for work between Florida and Georgia, including highway driving, I now carry bottles of oil in the vehicle and feel compelled to monitor and top off oil frequently out of concern that the engine could fail or stall while driving, potentially leading to a crash, injury, or loss of life. Based on my research, I understand I am not the only Kia Telluride owner experiencing this type of abnormal oil consumption or unexplained oil loss.

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.

I am the original owner of a 2020 Kia Telluride with 48,409 miles. My wife purchased it new. It has never been sold or transferred. It is fully covered under Kia's 10-year/100,000-mile Powertrain Warranty. What component failed and is it available for inspection? The engine is consuming excessive oil due to failed internal components—likely the piston rings. This has fouled the spark plugs and caused active misfires on cylinders 1,3,4,5. Codes: P0300, P0301, P0303, P0304, P0305. Kia acknowledges this defect in TSB ENG222, which defines consumption over 1 quart per 1,000 miles as abnormal. The failed components remain in the vehicle and are available for inspection. Has the problem been confirmed by a dealer? Yes. [Dealer Name] confirmed the misfire codes and excessive oil consumption. Despite being original owners with an active warranty, they refused to cover the repair. The advisor said they "only cover internal engine parts"—which is exactly what is broken. We were sent home with a flashing check engine light. Has it been inspected by manufacturer or others? No. Only the dealership. Kia Corporate has not inspected it. How was safety put at risk? A solid check engine light means active misfire and risk of sudden engine stall or seizure. Other Telluride owners report complete power loss on highways and intersections—no acceleration, no power steering, no power brakes. My wife and children drive this car. I fear for their safety every time they start the engine. Were there warning symptoms? Yes. Two weeks before the check engine light appeared, I noticed a slight shudder during acceleration that gradually worsened. The light came on solid, then began flashing within days. No oil light appeared. No other warnings. Kia advertised a 10-year/100,000-mile warranty. At 48,409 miles, they denied coverage for a known, documented defect. That is not a warranty. Not true. I request an investigation into the 2020 Telluride 3.8L engine. Thank you
