Filed Nov 9, 2026 · Engine, Fuel system · OH

When i am driving the vehicle about 20-50 MPH sometimes it jerks for no reason. I just got a full synthetic oil change and after 800 miles it was down one quart of oil. The dipstick went from full to minimum. Also the chack engine light turned on. The vehicle only has 80K miles and has had regular oil changes

I am reporting a serious safety concern involving my 2020 Kia Telluride SX with approximately 129,000 miles. The vehicle began experiencing delayed starting followed by a very strong gasoline odor. I also heard a hissing sound that continued after the engine was turned off. Due to safety concerns, I had the vehicle towed to a repair facility rather than continuing to drive it. The repair shop subsequently confirmed a significant fuel leak with gasoline spraying and pooling underneath the vehicle, reportedly extending from the front toward the rear. I am extremely concerned about the potential fire hazard this condition presents especially because I had been operating the vehicle before discovering the severity of the leak. I am requesting that the federal safety agency investigate whether this fuel-system failure represents a broader safety issue affecting 2020 Kia Telluride vehicles.

My engine failed from burning oil, even though the car has been maintained its whole life, 14 documented oil changes, roughly every 5,000 miles. • Jiffy-lube shop found the crankcase completely bone dry, only 4,344 miles after the last oil change. No reading on the dipstick. They added 6 quarts. Engine was knocking before and after. • No oil warning light ever came on, and no low-oil warning, just a check engine light and the knocking. • Towed same day to an independent shop. They found code P0524 (engine oil pressure too low) and say the internal noise is probably a rod bearing. Engine needs to be replaced. • The car goes into limp mode while driving. On the highway it dropped from 60 mph to 20 mph in live traffic with no warning. I couldn't safely get to an exit. • That's about 1.4 quarts per 1,000 miles, Kia's own bulletin ENG222 calls 1 quart per 1,000 excessive. • The car is not drivable, hasn't been repaired. This happened around 3 months after purchasing it second hand. Lots of other 2020 Telluride owners are reporting the same oil consumption problem.

Oil burns too fast causing oil changes to be required by every 3000 miles

Took my 2020 kia telluride for emission software update after being notified by the the dealership. Two days later my check engine light keeps coming on and off. I called the dealership and the said to bring it in only if the light is on. The next day my engine light once again keeps going on and off but now also my battery light keeps flickering on and off as well. My car is also slow to idle and when going slow speed my steering will shake. Also when I first start my car in the morning by RPM needle goes up and down as well as my a/c blow strong and then low matching rpm needle. My car seems to pull on hills it feels as there is not enough power to make it up the hill and my car also shakes. My car was running perfectly fine before I took my car to the dealership for this emission software update.

I had my most recent oil change on 2/20/26, and on 5/2/26 , the check engine light came on and I heard a knocking sound. I checked the dipstick and it was below the “low” mark. I hadn’t driven 3k miles yet!! I had to purchase 2 quarts of SAE 5w 30 oil to put into it. My vehicle is consuming more than 1 quart per 1000 miles.

While driving on a highway at approximately 50 mph, the vehicle suddenly lost acceleration without warning and was unable to exceed approximately 10–15 mph. This created a dangerous situation requiring immediate maneuvering across multiple lanes of traffic to reach safety. At the time of the incident, the check engine light was illuminated. Diagnostic trouble codes P0191, P2177, and P2179 were later identified, indicating fuel pressure irregularities and air/fuel imbalance. The vehicle was inspected by a dealership, which diagnosed a purge valve vacuum leak and faulty high-pressure fuel system components. The repair required replacement of the purge valve and high-pressure fuel system components. The failure involved components within the fuel/propulsion system and engine systems, which are controlled in part by the electronic control module (ECM). This resulted in a sudden and unexpected loss of propulsion while driving at highway speed. Prior to the incident, there were issues with refueling, including difficulty filling the fuel tank when near empty, indicating a potential developing issue within the fuel system. This condition created a significant safety risk due to the sudden and unexpected loss of vehicle speed in active highway traffic, increasing the risk of collision.

Description of Defect: My 2020 Kia Telluride experienced catastrophic engine failure and excessive oil consumption, which is a known issue for this model year (to the point that I had to sell it just 1 year after I bought it). The vehicle consumes oil at an alarming rate without any dashboard warning lights, or low oil pressure indicators, leading to sudden loss of engine power and potential stalling while in motion. This failure occurred at 93,200 miles, well before the expected service life of the powertrain. Safety Risk: Sudden engine stalling or power loss while driving at highway speeds creates an immediate risk of rear-end collisions and leaves the driver without power steering or braking assistance. The lack of any 'Check Engine' or 'Low Oil' light prior to the mechanical crisis meant there was zero opportunity to safely maneuver off the road before the vehicle became disabled. Furthermore, excessive oil consumption in this engine type has been linked to potential fire risks under the hood. Failure/Incident Details: Despite following all manufacturer-recommended maintenance, the vehicle suffered a major [Engine/Transmission] failure. Kia America has acknowledged the failure but refuses to provide transparency or assistance, despite Technical Service Bulletins (TSB SA428 and TSB 089) existing for these exact powertrain issues. This represents a significant safety defect that puts my family and other drivers at risk.

the car burns through oil at an absurd rate- no warning and then shakes when coming to a stop, then completely stalls and shuts off at stop lights and stop signs. I was stuck in an intersection with my two kids in the car. the car stinks of gasoline and does not seem right. Kia dealership claimed to have fixed the oil issue for over $350 and yet I still have to get frequent oil changes and top offs. NOT safe! I have read countless tings about this happening to Tellurides- especially 2020 and 2021s... my engine is probably ruined and Kia is doing nothing!

Engine light continues to come on and the vehicle sputters a lot while driving, it seems like it doesn't want to go. I have to give it more gas like I'm pushing it and when breaking the left front wheel wobbles when I'm trying to come to a stop I have to hold the wheel extra firm
