2021 KIA TELLURIDE Engine Problems

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.

Bought the vehicle in February. The vehicle is burning oil too fast. In 1 week 5 qts. I don't drive much as I work from home. Kia dealer wants thousands of dollars. I paid for extended warranty.

I purchased the 2021 Telluride (former owner of a Sportage, Rio and Sorento). I have our local mechanic handle maintenance and service. After paying $1,400 for a tune up to address misfiring, we quickly concluded the transmission was shot and my engine was burning theough every drop of oil before it was due for a change. I went to Kia of Des Moines, since it is covered under a 200k/20-year warranty. They replaced the transmission under warranty, I shared my mechanic details for records, and they told me they were going to do an oil consumption test. They sent me on my way, asking for me to return after 1,000 miles. I did (and then my car began shaking, but we thought it was due to snow conditions) and they quickly said, "Yes, it is an issue!" My Telluride burned through almost 2.5 quarts of oil in 1,000 miles. I left on 12/15, being told they would have direction from Kia corporate on next steps and acknowledged I need a vehicle loaner during repairs (single disabled mother, who has to travel safely). I did not hear back, chasing for updates. Yesterday, Steven text me saying I would need to authorize $1,600 engine tear down fee in order to confirm issue. I asked for Denny, the manager to contact me. I also called Kia Care, who said it is up to dealer. I am seeing so many issues with Tellurides burning oil. And, I do not have $1,600 to make my vehicle safe - that amount would make me sacrifice my home or another necessity. Google said to fight it and to submit a form to you also. I have to fight this because I have no other choice than to sell an organ. I will stock up on oil to keep filling it so my engine doesn't blow up, but have incredible fear of being stranded and not being able to get my vehicle towed or us home safely. If there is anything you can assist with, I appreciate it. I just found out my parent's 2023 telluride is burning too much oil too - they haven't got the $1,600 sticker, but I know that amount will wreck them also.

First there are holes in the block from a rod bearing coming off. It was leaking oil and started on fire. There are many recalls and law suits regarding this matter and we shouldn’t be on the hook for putting a new engine in.

On 11/01/2025, while traveling on the highway traveling at a speed of 80mph, my vehicle suddenly would not accelerate beyond 60 mph. I managed to exit safely, but this created a dangerous situation for both me, my daughter and other motorists . The next day, Firestone inspected the vehicle and informed me the engine contained zero oil—yet no oil light, check-engine light, temperature warning, or sensor alerts were triggered at any point. There were no visible oil leaks, suggesting internal oil consumption, which I had reported to Kia in October of 2024. On 10/21/2024, I paid $3,300 for a flywheel/ignition repair at a Kia dealership. When I dropped off the vehicle for that repair, I specifically reported abnormal oil consumption and requested it be checked. Kia did not diagnose or remedy the concern. The combination of: -Complete oil loss -No warning indicators -Sudden loss of power and inability to accelerate -Occurring at highway speed constitutes a critical safety defect. Drivers cannot take preventative action if the vehicle provides no indication of catastrophic engine failure until it is already occurring. This defect exposes drivers, passengers, and surrounding motorists to severe risk of collision or injury. Additionally, the dealership later provided a Carfax entry simple stating "car maintenance" on 10/22/2024. No record of what was repaired, indicating inaccurate or incomplete documentation. I am requesting that NHTSA: -Review this incident as a potential engine safety defect. -investigate whether other 2021 Kia Telluride owners are experiencing similar catastrophic oil -loss or lack of warning indicators. -Assess whether current recalls adequately address this failure pattern. -Determine whether an additional recall or investigation is warranted.

1. The engine consumed oil to where it soaked up all the oil in the engine likely as part of a piston ring failure. We have had it at the shop for the last 9 weeks, and cost to replace engine is $10,500 and because extended warranty explicitly wrote this out of the contract as this is a known issue and Kia has stated as such, but not a recall yet so nothing they will do to help. It is available for inspection, but we need the car back so likely not going to drag on much longer. 2. Yes, as no warning lights on the car came on, nothing out of the ordinary other than it just started acting weird and I took it in to get looked at, and was told there was no oil in the engine at all and this is known issue and engine is blown and we have to pay out of pocket to fix. This is extrememly alarming as we have 3 small kids that ride in that car daily and could have caught fire or broke down on the road at any point. 3. We have been told repeatedly by Kia and the extended warranty provider, JM&A, this is a known issue and many cases have been reported this year alone. 4. No, just the Kia dealership where we bought it. 5. There were no warning signs at all. No low oil light or notification came on at all leading us to believe there was a major problem.

Inspected by Kia for 2nd time due to vehicle suddenly shaking, overheating and turning off. First time fluids were low and replaced, kia stated should be fine but then while driving on the highway this past week same dangerous problem happened again suddenly where my vehicle started abruptly shaking making it hard to control, alerted overheating and immediately shut off. This time Kia diagnosed this issue is being caused by multiple hoses and seals failing due to degradation and leaking in multiple locations. Kia’s diagnostic repair inspection states heater core hoses(all), valve cover gaskets,Radiator Hoses upper & Lower, and other seals or connecting components are all leaking and need replaced. Have read online and communicated with other owners of the telluride in which many state same complaints of similar or same problem, therefore this seems to be a very common issue, a safety hazard and concern, not to mention a costly repair that seems to be a quality or manufacturing issue that may need to be evaluated further.

We own a 2021 Kia Telluride which we bought new, have changed the oil as expected and had the 100,000 mile check completed. It now has about 116,000 miles and has been a great and safe car, until now. On a random trip home, traveling on a busy highway, we had to pull over because we suddenly lost power. Our children were in the car and this was very dangerous on a very busy highway. We had it towed to our local garage and was told it was down 3-4 quarts of oil which wrecked the engine and we would need a new one! There were no warning lights for the engine or the oil at all. We are currently having the engine replaced at our very hefty expense as we have no other choice. I see this is quickly becoming an issue with the 21 Telluride and I hope that Kia will do something about it!

On or about December 2024, we noticed a hesitation or sputtering in the performance of our Kia. I contacted Ancira Kia who reviewed the vehicle, which displayed no warning lights. Since they couldn’t duplicate the issue, nothing could be done. On or about [XXX], the vehicle’s cooling fan engaged on its own while parked in the garage and revved up extremely high. This was the second time this had happened. Ancira Kia couldn’t duplicate the problem although they mentioned another customer was experiencing the same problem. A few days later, I was advised to bring the vehicle in for a sensor replacement. So far, the problem hasn’t recurred but I won’t know if it’s fixed until it never happens again. On [XXX], while traveling from Del Rio to San Antonio, TX, we stopped at a rest area. There were no warning lights visible and no performance issues noted until this time. When we started the vehicle to leave, we noticed a slight knocking that went away when we put the vehicle in drive. After our next stop, we noticed the knocking noise again when we started the vehicle and the noise dissipate when we drove. After the next stop the noise appeared to be louder so we decided to stop for lunch and let the vehicle cool down so we could check the oil. When we checked the oil, we saw there was no oil marking the dip stick. I took the vehicle to Ancira Kia who also found no oil marking the dip stick. The engine was ruined and needed to be replaced. None of the Telluride’s warning systems illuminated. No check engine or oil pressure lights lit up. This is a catastrophic failure of the Telluride which placed my husband and I in severe danger. We could have been injured and possibly killed had the engine seized while we traveled on the highway between Del Rio and San Antonio, Texas (150 miles). My vehicle is meticulously maintained at Ancira Kia. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Vehicle (2021 Kia Telluride) at ~94K miles received CEL P000A for (Camshaft Position - Slow Response (Bank 1)). Personally checked the oil before taking the vehicle to the dealership and there was very little oil, below the "L" line. Vehicle is burning oil fast, which more likley than not cause the P000A CEL. Vehicle would go im amd out of not being able to accelerate. Dealership wants me to pay diagnostic fees for them doing absolutely nothing other and resetting the code and conducting an oil change. Vehicle is a CPO which has a 10y / 100k mile warranty which seems like the dealership is trying to prolong until vehicle is out of warranty to diagnose it correctly. Engine is burning oil and needs to be replaced but the dealersbip wants to play games with customers.

Rear shock failure for the second time. This time in under 9 months. Front crash detection constantly goes off in cold snowy weather or rain. engine issue is frequent popping sound in exhaust and causing dirty oxygen sensors

The contact owns a 2021 Kia Telluride. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The contact stated that the check engine warning light had previously illuminated; however, the warning light then turned off independently. The vehicle was taken to the dealer where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 63,000.

Mileage: 63,000

I am reporting a serious and ongoing electrical and transmission issue with my 2021 Kia Telluride (VIN: [XXX] ). The problem began under 20,000 miles and has continued intermittently for years, progressively worsening. My vehicle is currently at ~99,600 miles and under extended warranty. The key safety concerns include: Transmission Lockout: The vehicle intermittently becomes stuck in Park and will not shift, even with the brake depressed. No-Start Condition: The vehicle will randomly become completely unresponsive—no dash lights, no infotainment, and no engine start. Electrical System Failure While Driving: Multiple safety systems fail mid-drive, including: Loss of power steering and air conditioning Random activation of ESC, TPMS, Collision Assist, Blind Spot, and Parking Brake warnings Infotainment screen turns off while in motion Component Failures Due to Electrical Shorts: Both the radio and the backup camera were diagnosed with shorts and had to be replaced under warranty. Brake Lockout Post-Shutdown: The brake pedal becomes very firm and the vehicle will not restart until hours later. Most concerning, my wife and children have been left stranded in the disabled vehicle on multiple occasions due to these issues. The car has been in the shop several times — around 50,000 and 80,000 miles — but no permanent resolution has been found. This is a clear and escalating safety hazard. The failures affect critical systems while driving and leave the vehicle unpredictably disabled. Kia has been made aware and an escalation is underway, but I am filing this report to ensure the NHTSA is aware of the pattern and potential danger these failures pose to others.

I recently brought this 2021 kia telluride used from a local dealership with 103,000 miles and everything was great , until yesterday i notice that when coming to a stop the car would sputter i thought maybe it was just a one off because i recently got recall work done at a kia dealership and they checked over the vehicle and everything was fine. so this morning im driving to work and it happens again so i check the oil and its completely empty i've went less than 3k miles on this oil change something needs to be done no warning to lights

The last two times I have been due for an oil change my car has been completely empty. It is 4 years old and burning 4/5 quarts of oil between oil changes. Yesterday for example, my oil notification came on, today I start my car and my engine light came on, check the oil and nothing. Put 2 quarts of oil in it so I can make it to the mechanic tomorrow. This should not be happening on a 4 year old vehicle

Excessive Oil usage to the point of no oil on dip stick yet engine doesnt alert to low oil or pressure. Engine started sputtering and stalling which is why we even checked. Oil changes are done on normal basis. This seems to be a common complaint on the Internet now that I am looking into this. This car is 4 years old and should not be having engine trouble.

March 7th my engine light came on while pulling out, in reverse, of a parking spot. My engine light also turned off on March 7th later in the day. Between then and now, it came on and went off a few times, but my car seemed fine. On April 1, the light reappeared again while backing out of a parking spot. My car was not working like normal. It was shaking a bit and seemed kinda stuck, but also very slowly moving in reverse. Shaking stoped once I put it in drive but the engine light stayed on. I took it to my mechanic and the code given was “internal engine failure”. He told me should be under warranty, so I called the dealership. Service guy told me no active recalls and also that I was outside of the warranty. I have 118,800 miles. Vehicle is less than 4 years old. I am waiting to hear back from my mechanic as to how much repairs should be. I don’t know if he is thinking I need a whole new engine or just a part.

What component or system failed or malfunctioned, and is it available for inspection upon request? While driving the vehicle, it intermittently hesitated during acceleration until there was a very loud popping and banging noise, it was sudden and very loud. We experienced a complete and sudden loss of power. The car then proceeded to send off nearly every alert on the dash, and threw a code which was P061B. The engine blew out, the oil pan was fractured by ejected connecting rod (visible from underside). How was your safety or the safety of others put at risk? When the engine blew out in the fast lane, our physical safety was at risk due to the immediate loss of control and power, the inability to merge, and stopping next to the center divider in a high-traffic area. In the car were my wife and 3 kids. Psychologically, the fear and panic of our family being stuck, the stress of making quick decisions, and the vulnerability of being exposed to fast-moving vehicles added significant pressure. In that moment, our family was left utterly helpless, fearing for our lives in the face of an overwhelming, life-threatening crisis. Has the problem been reproduced or confirmed by a dealer or independent service center? The car is currently at a Kia service center in Santa Rosa, Ca. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? UNKNOWN, the vehicle is at the service center in Santa Rosa, Ca. The vehicle was also inspected by a local mobile mechanic. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no alerts, warning lamps, or messages, the car did experience some hesitation during acceleration but it was intermittent.

While driving under normal conditions the engine started making a weird sound. Shortly after the power steering wend out and the dash, lights and infotainment system went dark. The engine shut off completely and will not go back on. This is after bringing the car in for continuous issues and always being told they are resolved and the car is fine.

My engine started jerking when stopped. Then the electrical started acting up, like the windows wouldn't roll back up. Then the engine just shut off while I was driving.

Engine oil pan gasket and oil filter housing have failed shy of couple hundred miles of manufacturer warranty

I am the original owner of our 2021 Kia Telluride and we follow the manufacturers recommendations and ensure our oil is changed every ~10K miles. Our Kia was recently serviced at Nationwide Kia in Timonium Maryland in April 2024 and had the oil changed. As I was driving today, [XXX] the Oil Pressure Warning Light came on. When I pulled over, I checked the dipstick and it was below the low level. I immediately put in 5 quarts of oil and the light remains on. I contacted Kia and will be taking the car in for them to assess; however, I am urging that a recall for this issue is addressed. This is a common problem that others are having as well. This could have caused significant issues as I work in the inner city of Baltimore and breaking down would not be a good thing for a [XXX] Please ensure Kia does the right thing and issues a recall for this issue.

Car was being driven when it began to slow down. Pulled over and smoke was coming from under the car. Car would not start again. Once at dealership, found there was catastrophic engine failure due to a rod that put 7 holes in the engine. Also, car was low on oil despite an oil change less than 60 days prior to this incident.

Since November 2023, the car's engine has been burning oil. There are no leaks in the driveway. On January 8th (87,000 miles), I took the Kia Telluride for service at Mission Viejo Kia for a Check Engine light. They said the car had low oil and indicated that the cause was a leaking oil housing. They completed an oil change and added new oil. On February 19th (90,000 miles), the AC drain was clogged and water was entering the passenger side inside the vehicle. In addition to this fix, Mission Viejo Kia noted that the oil level was down to 1/2 quart. This was only 3000 miles since the last oil change. On April 6th (95,000) completed another oil change at Ramona Tire, where I was getting new brakes. They did note very low oil. June 24th (96,600 miles), the Telluride started rattling and stalling at lights. Upon inspection, Mission Viejo Kia determined it was due to low oil again. July 9th (98,000 miles) I inspected the oil dipstick and saw barely any oil. I took it to Mission Viejo Kia and it is currently awaiting direction from Kia Corporate for the next steps. This was only 2000 miles after the most recent oil change. There was no oil leaking in the driveway. My research has shown that Kia Tellurides and other Kia/Hyundia are experiencing rapid oil consumption. This eventually could lead to engine failure and catalytic converter failure. Class action suits have been filed and dismissed recently. My 100,000 mile warranty is coming up. This complaint is to document the issues I have been experiencing for any possible future action.

My car started having an oil leak on [XXX] of 2023 which is the date reported to Mark Martin Kia. They replaced the oil pan on [XXX] 2024 and said that the issue was fixed. I drove it home, and the next day oil was still coming from my engine. I took it back and they said that the housing was what was leaking. The tech told me that 10k parts were on backorder so I'd have to keep putting oil in until the part arrives. Over a month went by of me having to pour oil in. [XXX] was when they fixed it. [XXX] my engine is no longer functioning. Major nock. Needs replaced! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Excessive engine oil usage. No low engine oil level. Engine overheating.

My wife had placed our two children in the car in their car seats. She attempted to start the vehicle by pressing the brake and the starter button. Though all the dome lights and other normal electrical items were on at the time, as soon as she attempted to start the car, it instantly went dead. There was no power to anything, and all the interior dome lights did not work. No matter how often she attempted, she could not start the vehicle, even with accessory mode. It was almost as if the battery had been suddenly removed from the vehicle. At no point was the car moved outside of park. My wife removed our two kids from the vehicle, and shortly after, they were secured in our other vehicle; without my wife being in the Telluride, the car turned on itself. All interior lights were on, and the car was functional. She found that while the radio was on, the HVAC that had been on was now off. In addition, the fuel performance reset to zero. She turned off the vehicle, and we could not reproduce the issue. From a safety perspective, this was very unnerving as it involved our children in our car, but also that the car started on its own after five minutes. If we were not at home and the car could have been running in the garage without our involvement. All regular maintenance and satisfaction of recalls had been completed by a Kia-authorized dealership before this event.

While at a red light after exiting the highway, the vehicle lost all power and functionality. The car was in drive, and the brake was pressed in. No buttons had been pressed to shut down the vehicle. I had no power and no ability to restart the vehicle. I placed the vehicle into park and attempted to turn on my hazard lights. Unfortunately, there was no response from the vehicle, and though I was interrupting traffic, I could not provide any visual indicators to oncoming traffic. After moving the vehicle into park, I was unable to move the car into neutral. After approximately five minutes, without the brake being pressed or any button is pressed, the vehicle turned on its own. I was able to move the car into drive and continue to function as expected. Prior to this, I had used the vehicle to drop off my kids at daycare (which required turning on the vehicle, driving, and turning off the vehicle). This event occurred roughly 40 minutes after a mix of highway and city driving. From a safety perspective, this was very concerning as I had no way to indicate to other drivers that my car was not driveable. Fortunately my children were no longer in the car. I was very concerned that not only the car lost all power and functionality, but was more concerned that the car started on its own. I was also concerned that if I had not moved the car to park and somehow it turned back on if left in drive what potential damage could have been done to me, another vehicle and potential injury 30K service and all recalls had been satisfied prior to this by an authorized Kia dealership.

When starting in the cold (approx 30 degrees F or less), the Kia has a very high pitch squeal. The sound appears to be coming from inside the engine and is NOT a pulley or slipping belt. There is a lot of discussion about this issue on the web, and Kia has not issued any resolution to any of the customers who have complained and taken to dealers. This link is not my car but is the same noise - if necessary, I too have my own video I can share. https://drive.google.com/file/d/1-68J5bocqVxzPLIDpabmgd_St6CMoxky/view Note: Dealer was able to replicate, and has a video of the issue from us, but has stated that they do not know how to fix.

On cold mornings when the temperature falls below thirty degrees, the car emits a loud screeching noise from the area of the throttle body. I had the belts and pulleys checked at my last oil change (two weeks ago) and they were fine. It it’s distinctly coming from the area of the air intake and throttle body. The high pitched squeal will last for about 10 seconds and stop. By the time the vehicle gets to the dealer, it has warmed up or the temperature has gone above 30.

As I started the car, it began to shake and shudder while idling. And the check engine light turned on. I could smell the unburied gas inside the car.

021 KIA TELLURIDE, FEBRUARY 13, 2021. TEMPERATURES ARE SINGLE DIGITS OR BELOW AND GOT WORSE AS THE WEEK WENT ON. STARTED THE ENGINE AND A LOUD SQUEAL OR WHISTLING NOISE CAME FROM THE TOP OF THE ENGINE. LAST ABOUT 30 SECONDS THEN SLOWLY STOPS. ENGINE ALSO STARTS TO SOUND LIKE IT HAS MORE POWER ONCE NOISE STOPS. BEEN GOING ON FOR THE LAST 8 DAYS. BELTS AND PULLEYS SEEM TO BE WORKING FINE AND CANNOT SEE ANY ISSUES. SOUND LIKE IT IS COMING FROM UNDER THE ENGINE COVER BUT DO NOT WANT TO REMOVE COVER CAUSE TOO COLD AND DO NOT WANT TO JEOPARDIZE WARRANTY STIPULATIONS. CONTACTED MIDWEST KIA IN WICHITA, KANSAS. SENT THEM A VIDEO AND THEY THINK IT IS A VACUUM LEAK OF SOME KIND. MIDWEST KIA SAID THEY CANNOT REPORT IT TO KIA UNTIL THEY CAN SEE THE CAR BUT WE ARE 2 HOURS AWAY AND CANNOT GET OFF WORK TO TAKE IT AND NEED OUR CAR FOR WORK. I OWN A MORTUARY AND HAVE FUNERALS AND MY WIFE IS A TEACHER AND CANNOT GET SUBSTITUTES DO TO COVID. I SAID BASED ON MY RESEARCH IT SOUNDS LIKE INTAKE MANIFOLD. ON THE KIA FORUMS, MANY PEOPLE EXPERIENCING THESE VERY COLD TEMPS ARE EXPERIENCING THE SAME NOISE AND ENCOURAGED ME TO REPORT THE ISSUE. I FEEL IT IS COLD RELATED AND HOPE KIA LOOKS INTO THIS PROBLEM. THIS ONLY HAPPENS WHEN THE CAR HAS BEEN SITTING FOR SEVERAL HOURS. IF WE USE IT OFF AND ON WITHOUT SITTING TOO LONG THE NOISE DOES NOT HAPPEN. CAR RUNS GREAT ONCE THE NOISE STOPS.

MY ENGINE LIGHT CAME ON ON THE FIRST COLD MORNING. WHEN THE ENGINE LIGHT CAME ON, IT STARTED SPITTING AND SPUTTERING AND IDLED FUNNY. I SHUT IT OFF.
