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.

Incident

May 2, 2026

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

My vehicle has an oil consumption problem that the dealership and every other Kia dealership knows about. They are Facebook groups about the Kia Telluride oil consumption problems. I’ve had my vehicle in the shop countless times and it’s cost a lot of money. It now needs a new engine along with every other Kia Telluride on the social media groups, complaining about the oil consumption and their engines going bad and needing replaced. The dealership refuses to replace my engine because there’s no recall.

I have a 2020 Kia Telluride that I bought brand new from Kia. I have performed regular maintenance on the vehicle and performed the repairs required by any recalls. When my vehicle surpassed 75k miles, the vehicle started having issues with excessive oil consumption. I had my vehicle serviced at 75k miles with the oil changed. When my vehicle was passed 79k miles, the vehicle started stalling, piston misfiring, and engine started vibrating. I took it into the dealer, and they performed diagnostic tests. The determined pistons were working fine but my oil level was very low. This was around 4k miles after my oil change. Kia requires oil changes every 7500 miles. I had the dealer change the oil. Once again, when my vehicle was approaching 4500 miles, the vehicle started to vibrate, piston was not filing properly. I checked my oil level, and it showed very minimal oil on the dip stick. The oil level was well below that was needed for the engine to properly operate. I put closed to 5 quarts of oil to get the engine to the oil level it needed. I am concerned that the excessive oil consumption can lead to the vehicle stalling on the road resulting in collision with other vehicles resulting in bodily injury or harm. According to Kia the oil consumption is fine. How is consuming 5 quarts of oil in 4500 miles fine when the manufacturer states oil changes are required every 7500 miles? The engine itself has a capacity of 6.9 quarts. At the rate my engine is burning oil, I would need over 7.2 quarts of oil to drive 7500 miles. Additionally, having an engine continuously operating with low oil would result in engine damage and thousands of dollars in repairs. The problem I am having in my vehicle is experienced by thousands of Kia Telluride owners. It's the same problem Kia has had in the past with other models. Kia is trying to avoid repairing their defective vehicle and placing the burden on the consumer.

My 2020 Kia Telluride completely stalled on me on my way to work. The vehicle was not smoking and it seemed like it went on accessory mode. I had the vehicle towed to Kia Dealership in Perris to get it checked out and was told by Olivia that no codes were read when doing a diagnostic and that my engine seized. I had purchased an extended warranty through AGWS. AGWS reached out to me to request the vehicle service records which I emailed over as Subject: [XXX] to [XXX] Today March 21, 2024 we receive a call from Olivia stating that my warranty will not cover the cost as they're claiming that we failed to service the car. Our vehicle was services as advised and stated using the appropriate Synthetic oil. I was informed that they would be breaking down my engine to see where it went wrong as there were no codes read. They also stated I had to pay for the engine breakdown $200 per hour and it would most likely take 8 hours (According to Kia). Now, I've gone on many online forum and many people have experienced this problem with their 2020 Kia Tellurides all under 75,000.00 miles. I contacted Kia Corporate as well but that got me nowhere. I don't understand how these vehicles don't have a recall as of yet for these seized engines. I also don't understand how following the oil recommendations for oil changes is suddenly considered "Lack of service". No one is willing to work with me and suddenly it's my fault that I bought a faulty vehicle. Thank [XXX] I was able to putt to the shoulder of the freeway safely as this is my family vehicle where I drive with my [XXX] and [XXX] . Please investigate as it could be a possible recall.

Vehicle went on accessory mode while driving on the freeway. No codes were read at dealership and now they're claiming its a seized engine. They will not help me out and are claiming my extended warranty will not cover the cost due to the lack of maintenance on the vehicle. Mind you, I did my oil changes as expected using the recommended synthetic oil. Why hasn't there been a recall on this vehicle yet for the danger this creates as this is my family vehicle where I drive my newborn to and from his daycare and appointments. We are very lucky we were able to pull the vehicle to safety and to the shoulder of the freeway before an accident occurred.

For the past year at least I've had check engine light come on and turn off before being able to get in for a diagnostic. Along with the entire engine shutting down while idling, parking, turning. Whole electrical system failure. Can't move the steering wheel. Have to restart the car and it takes a few tries. Sometimes the car will be off and will not start back up for a while.

My check engine and oil lights have come on more than once around the time of needing an oil change. During that time, the engine bucks, and the RPM revs high and low. The Kia Service Dealer, both times, stated that the light was coming on because the oil was low. The first time they replaced the spark plugs as a precaution, since the check engine light state miss-firing. That didn't fix the problem, because the light came one again right before the next oil change was needed. And this time, the car actually stalled out at a red light. They said the oil was really low the second time. I asked where the oil could be going. They said it wasn't leaking that they could tell, and that Kia says its ok to lose about a quart every 1000 miles. I don't agree with that, especially with a 4 year old car. So I had another family member drive the car while I followed, and sure enough I saw black smoke coming out of the tail pipe. So, the engine is burning the oil. On top of all this, I noticed that the screen (which they just did a software update on) right side compass keeps appearing suddenly and then disappearing, without anyone touching the screen. Then I noticed yesterday, after I parked. The Emergency Brake turned out all by itself, without me pulling the button up. The red light indicator came on also, then turned off and on and off. Lastly, the forward movement button on the driver side button doesn't work, which I thought was supposed to be repaired as part of the last recall. All in all, I am afraid to drive this car because I think the engine or seat is going to catch fire at any moment.

My 2020 Telly has a random vibration. When it appears it can be felt throughout the vehicle. Just as quickly as it appears it disappears. Mostly felt with acceleration/when changing gears (right after). Also there have been a handful of times I've attempted to go from a stopped position or pulling into traffic and the car just sits there. It does not rev or increase rpm's, it does nothing. Then after about 2 seconds it will just calmly go as if I had just pressed on the gas. This is very scary when it happens while pulling into traffic or attempting to cross over traffic... Because when it does start to go you are now 2 seconds behind where you should be and I was almost hit. Had a similar issue with my Tucson and Hyundai fixed it ASAP.. it was the transmission clutch. Also having an issue with my CV axle/joint/boot. It's leaking but it is not broken or cracked etc. It's just leaking and spitting greas/fluid all over the wheel etc. Trying to find a part for it that is not at the dealer is not easy but the dealer wants 400 just for the boot (not installed). This is ridiculous and price gouging. Check the Kia forum and you will see many people with these same complaints/concerns that need to be addressed BEFORE someone gets hurt. Having your vehicle not go while pulling into traffic is SERIOUS.. fix it Kia! I have 2 shops that have confirmed there's an issue, felt vibration, picture of leak, instead what's up with the transmission AWD but is believed to be driveshaft/transfer case related. 64,440 miles currently. Issues started at 62,261.. also I contacted crown Kia(st. Pete FL) regarding windshield replacement because I have a crack that is growing after repair. I have the letter (customer and dealer regarding cheap glass "Goodwill repair" and they knew nothing about it. I produced the letter and have heard nothing from them. Dealerships hate doing anything that won't bring a dollar. KIA FIX MY ABILITY TO SAFELY GO IN TRAFFIC PLEASE. SAVE LIVES PLEASE NOW THANK YOU

My vehicle is having issues with its digital readings of the temperature and gas miles. I went to get 25$ in fuel yesterday. When I got to the station I had 75 miles to the gallon on the monitor. After adding the 25$ the analog meter changed but not the digital. I had a similar incident in the summer with my temperature Guage reading 84 degrees when it was actually 103 degrees outside. It did however pick back up later in the day but now I'm concerned because there's other drivers reporting the same issues on the telluride forum. I also just had a recall fixed on my vehicle about 2 weeks ago that was an electrical problem as well.
