2020 Kia Telluride: check engine light

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

Kia Tellurides produced between Feb and Dec 9, 2019 had software issues related to the torque converter solenoid pressure (too low to securely mate torque converter clutch) and over-sensitivity trouble code P0741, which indicates torque converter clutch slip. Kia fixed this software issue for the remainder of 2020 production, starting Dec 10, 2019. Kia also issued TSB TRA089 in April 2020 to reflash the transmission control unit (TCU) but would only do this on vehicles with an active check engine light (CEL), rather than reflashing all affected vehicles with proper TCU firmware. Many customers, including myself, were unaware of the clutch damage that took place as a result of outdated TCU firmware and drove our vehicles with constant micro-slip events, which prematurely wears out the torque converter clutch. This is why there are so many torque converter failures on 2020 Kia Tellurides between 80~120k miles. I now have a 2020 Kia Telluride with 126k miles built on Dec 6, 2019 (3 days before the TCU firmware was fixed), and my torque converter is slipping badly. It is now a safety concern because the vehicle is unpredictable and may or may not properly engage the torque converter. The torque converter must now be replaced and fluid flushed; however, metal shavings also have negative impacts on the transmission and could require a full transmission replacement. This issue is not normal wear and tear. It is a known clutch slipping issue that Kia chose not to address until customer vehicles break down catastrophically. Now owners are on the hook for expensive torque converter and transmission repairs, while this expense could have been avoided with a TCU reflash that Kia knew about for nearly 7 years - since Dec 10, 2019. After this date, vehicles came stock with updated TCU firmware that applied sufficient clutch solenoid pressure to prevent constant microslip events and premature torque converter clutch wear out.

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.

The contact owns a 2020 Kia Telluride. The contact stated that while driving approximately 15 MPH, the vehicle hesitated to maintain automotive power. The check engine warning light was illuminated. The vehicle was previously repaired at a local dealer for an unknown recall associated with an engine oil leak. The vehicle was towed back to the same local dealer where it was diagnosed and an engine flush was suggested, and the contact was informed that six fuel injectors needed to be replaced as a possible repair. The manufacturer was made aware of the failure, and a case was filed. The approximate failure mileage was 109,000.

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.

Vehicle experienced significant drivability issues including shaking/clinking at speeds over 50 mph, check engine light, and reported two-cylinder misfires. Engine oil level was critically low, not registering on the dipstick, requiring approximately 2 quarts added to continue driving. An independent mechanic inspection found excessive oil in Cylinder 2 and assessed that oil was likely leaking past the piston rings and burning, recommending a bottom-end rebuild or engine replacement. Kia dealership (Sunset Kia) inspection subsequently found a score mark in Cylinder 6 and two external oil leaks (oil pan gasket and oil filter housing). Kia approved goodwill repair of the external leaks only, after which I was instructed to drive approximately 1,000 miles for a follow-up oil consumption test. After that period, the dealership confirmed the engine was still consuming oil beyond the external leaks. Kia Corporate took approximately three weeks to review a goodwill request for engine replacement, ultimately denying it. During this three-week period the vehicle remained at the dealership, and I incurred over a week of out-of-pocket rental car expenses due to no loaner vehicle being available and no transportation assistance offered. The vehicle has fewer than 100,000 miles. I am concerned this reflects an internal engine defect (oil consumption/piston ring or cylinder wall issue) affecting the vehicle’s safe operation, given the drivability symptoms (shaking, misfire, near-zero oil level) that initially prompted this investigation.

A continuation from my last post. I brought my car back to the dealer.The worker came out to inspect my car and he lifted the hood and he said I had a loose negative battery cable and that I had the wrong battery in my car. He said that might be the cause of the flickering lights.My car was at the dealership for three days before I was called to come pickup my car.He stated they found another service update that my car needed P0471 and that cleared my check engine light and the battery he said once again I have the wrong battery in my car and they were only able to tighten the negative cable so much.I explained to him that it was the correct battery because I went to Walmart where the battery was purchased and they auto manger printed out that paperwork that shows it is the correct battery for that car.Then he had me sign for my car and I left.While driving home my battery light stared flickering again.So I called him and said I thought you were able to tighten the negative cable to the battery. He then said they did the best they can do because it is the wrong battery.After he got off the phone all my lights on my dashboard lit up.My car seemed possessed.My steering locked up and brakes were not working.Scared and crying i called him back and was telling him what was happening to my car.He said once again it was due to battery. Crying I said I'm scared what do I do?He advised me to put my car in netural and try to pull off to the side.I explained to him that I was on the freeway in 5pm traffic my hazards, signals and brakes aren't working.I then asked him what do I do once I can stop the car.Do I bring it back to the dealership? He said the only thing they can do if i bring it back is to have me buy a new battery.At this point the car completely turned off.I was able to roll off the freeway then my car stopped completely violently as if someone slammed the the brakes.Now they want me to buy a new alternator and transmission.Car had no issue before taking it in.

Vehicle experienced catastrophic engine failure while traveling approximately 70 mph on a highway. I heard a loud popping noise and immediately lost power. The vehicle would no longer accelerate normally and I was forced to pull over. White smoke was visible from the engine compartment, and a large amount of engine oil leaked from the vehicle. This failure created a safety risk because it occurred at highway speed, resulting in sudden loss of power while traveling with surrounding traffic. The vehicle required towing and could not be driven from the scene. Prior to the failure, the vehicle had exhibited symptoms beginning around May 11, 2026. A check engine light illuminated and an independent mechanic diagnosed a cylinder 3 misfire and replaced the ignition coil. Following that repair, the check engine light returned. Additional symptoms included stalling at idle, knocking noises from the engine, and intermittent oil pressure warning lights. The vehicle was subsequently inspected by an independent mechanic who diagnosed a thrown connecting rod with damage to the engine block, including a hole in the engine near the transmission area. The mechanic advised that the engine requires replacement. The damaged engine is currently available for inspection. The vehicle has not been inspected by the manufacturer. No injuries or crash occurred, but the sudden engine failure and loss of power at highway speed created a significant safety concern.

I own a 2020 Kia Telluride currently with approximately 91409 miles. The vehicle has a repeatable transmission issue during acceleration, most noticeable around 40 mph when the transmission shifts. The vehicle shudders/hesitates/jerks and does not accelerate smoothly. This creates a safety concern because the hesitation occurs during normal acceleration and could affect merging, passing, or maintaining speed in traffic. I brought the vehicle to Vision Kia of East Rochester, 201 East Linden Ave, East Rochester, NY 14445 on 2/4/26 at approximately 88067 miles. The Kia service manager/technician duplicated the concern during inspection/road test and stated that the issue is related to the torque converter damper clutch. However, I was told the dealer would not repair the vehicle unless a warning light/check-engine light comes on. No warning light is currently illuminated. I am reporting this because the transmission defect has been observed by the dealer while the vehicle is still under warranty, but no repair has been authorized. I am concerned that the condition may worsen and could cause delayed acceleration or unsafe drivability.

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.
