2021 KIA TELLURIDE Power Train Problems

Component/System Failure: The engine and lubrication system appear to be malfunctioning. The vehicle has repeatedly experienced sudden engine shutdown while stopped at traffic lights and during low-speed operation. The dealership has identified oil leakage involving the oil pan and oil filter housing and has indicated there may be an internal oil leak within the engine. The vehicle is available for inspection upon request. Safety Risk: When the engine shuts off unexpectedly, the vehicle loses propulsion in active traffic. This creates a risk of rear-end collision and prevents immediate maneuvering out of traffic flow. The loss of engine power while stopped or moving at low speeds presents a serious safety hazard to myself and surrounding drivers. I am concerned that the suspected internal oil issue may lead to catastrophic engine failure while driving. Dealer Confirmation / Reproduction: The issue has been reported to the dealership multiple times beginning in January 2025....

The vehicle decelerated in the highway, from about 70mph to 40mhp with no warning, no check engine light, and no previous symptoms, sounds or other indicators. The vehicle was brought to the dealer who advised the high pressure fuel pump went bad as well as the solenoid and OCV harness, causing oil to be forced through the harness. KIA refused to cover the repairs at 74k miles and it was fixed at the owner expense, even after KIAs long history of failed high pressure fuel pumps in many other models. We were in the fast lane and were almost hit by a semi, who was thankfully able to move over at the last minute, narrowly averting the deaths of both my children, myself, my nephew and brother at aprox 4am.

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...

The oil filter housing is made of plastic and it cracked causing a major oil leak. There were no warning lights on the dash. Our family had just gotten into the car to visit family for Thanksgiving. I ran back into the house to get something and when I came back I first saw a large puddle of oil where the car was parked then I looked at the car and could see oil streaming out. At first I thought the filter or the oil drain plug had come loose. We had our local mechanic look at it and he said it was a common problem they see with plastic housings instead of metal. We called the closet KIA dealership and they said it was a known problem but KIA has not issued a recall. I searched online and found many complaints. If I had not noticed the leak we...

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...

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.

Vehicle transmission has been slipping and Sutter since around 30k miles. Dealer has test vehicle and agrees but will not repair due to no codes in PCM or ECM. Vehicle stalled almost causing another vehicle to clip rear of vehicle. Issue is getting worst.

I’ve taken my vehicle to Kia a few times about my transmission sputtering and the first time they told me I needed a transmission flush, I paid $250.00 to have it done just to have it continue to happen and every time I bring it there they say they aren’t seeing or feeling anything. It’s still doing it. Also I opened my sunroof and it hasn’t been used much since I bought it in 2022 and now it’s stuck open. Took to the dealer just for them to tell me I have to pay $140 diagnosis fee and my warranty most likely won’t cover to fix it. I purchased the platinum bumper to bumper warranty!

Vehicle surges when at a stop. Normally RPM run about 500, when the vehicle surges the RPM's jump without notice to 1000 or more and the car acts like a race horse wanting to get out of the gate. Heavy pressure on the brake is needed at all times when stopped at a light, for a turn, at a stop sign. This started around 82K miles and was reported to the dealership. Dealership could duplicate issue and no codes were thrown. Again reported at 89.5K, 91.6K, 99.6K, 103.5K with same response from dealership. Contacted KIA and received a case number in case the issue is a warranted situation and is uncovered after 100K mile warranty expires.

I was driving and stopped in the center lane and the SUV would not move. I was left in an unsafe position. I was there about 10-15 min and got pushed out of the road. I turned the suv off and on a few times with no difference in response. I let the suv sit there about another 5 min and was able to move the suv and the problem has not occured today but it does seem to be shifting a little hard and have noted that recently. I saw something online about NHTSA ID numbers 11425571 and 11354498. that might be relivent but I was trying to to find more information on those.

There is an ongoing problem with the AWD coupler on every model year of this vehicle and other KIA/Hyundai AWD vehicles. The problem occurs at lower speeds (35mph or less) while turning, and/or when starting from a stop turning either left or right. The vehicle produces a binding or slipping feel in the rear wheels along with a clunking noise from the rear of the vehicle. This is dangerous because the vehicle loses traction/power when its needed most during slit second decisions. Many of these couplers are failing early in the life of the vehicle. Mine is at 27K miles, however I believe the problem started long ago, closer to 15K miles. Kia knows about this issue but has failed to come up with a reliable solution. This is four model years now with the same issue. Kia has released TSB after TSB on this, and even recalled it early...

Vehicle has a vibration at 60-75 miles per hour. It's a rhythmic vibration that you can feel in the gas pedal and sense in the front of the vehicles drivetrain. Kia has a TSB about this issue. Kia TSB 099. But our vehicle is past the 60k mile warranty period that would protect it. Kia knows that some cars manufactured between the start of production and February 2021 have this issue. They know which production lots of the affected parts have the issue, yet they refuse to make it a recall issue. Anyone who is unlucky enough to lapse the warranty period is such with a detective part that Kia is fully aware of. The issue is so difficult to diagnose, I had to go to two dealerships to even get an answer about what the issue might be and that the warranty will not cover it.

As I was driving down the highway in the rain, my check engine light came on and I was unable to accelerate my vehicle over 30mph and the speedometer stopped working. I was turning onto the road I live on, so I was able to make it home. I then shut my car off and turned it back on about 5 minutes later, and that issue was no longer happening. I had an upcoming appointment for an oil change at a Kia dealership, so I told the dealership about the issue. They told me that they hooked their computer up to the car and it was showing that there weren’t any issues showing and the only way that they would be able to see that there was an issue is if the vehicle was brought in while it was malfunctioning. Also, the mirror function on my vehicle where the side...

At around 40,000 miles my Telluride start to have issues shifting at low speeds and when cold. By the time I hit 50,000 miles it was happening all the time. It began sputtering almost everyone I accelerated causing it to hesitate on highways. After two trips to the dealership they said I need a whole new transmission. My car is only at 56,000 miles and is no longer considered driveable until it is replaced which of course, the part is on back order.

We were driving the car and it began lurching unpredictably. It was difficult to maneuver safely. It is now 3 weeks past that time and my Kia has been at the dealership this entire time. The dealer says that they cannot do anything without checking with Kia HQ and each time they do, Kia has them run another diagnostic.

I DROVE MY BRAND NEW TELLURIDE OFF THE LOT WITH 11 MILES ON IT. BEFORE I GAINED SPEEDS OVER 50MPH MY VEHICLE WOULD JERK AS IT CHANGED GEARS AND THE RPM INCREASED. AFTER I STOPPED AT STOP SIGNS OR RED LIGHTS AND THEN BEGAN TO ACCELERATE AGAIN, THE CAR WOULD JERK, THE ENGINE WOULD REV UP AND NO ACCELERATION WOULD HAPPEN. IF I KEPT PRESSING THE GAS, EVENTUALLY THE CAR WOULD JERK AGAIN, CATCH THE GEAR AND DRIVE. THIS HAPPENED EVERY SINGLE TIME I WOULD STOP AND GO AGAIN. OVER SPEEDS OF 50-60MPH I DID NOT HAVE THIS PROBLEM.

WHILE DRIVING THIS VEHICLE AT 65-70MPH A HIGH-SPEED LOW-TONE OSCILLATING VIBRATION CAN BE HEARD AND FELT AND CONTINUES THROUGH 75MPH.

THE VEHICLE STARTED VIBRATING WITHIN A MONTH OF THE PURCHASE AT SPEEDS BETWEEN 60-80. SEVERAL TRIPS TO KIA WITH KIA TECH LINE AND THEY DENY THE VEHICLE HAS AN ISSUE. THEY SAID THE VIBRATION MEASURED WITH A PICOSCOPE WAS WITHIN THE NORMAL RANGE. AFTER FIGHTING WITH KIA CONSUMERS, I TOOK IT TO A DRIVESHAFT SPECIALIST FOR AN INDEPENDENT DIAGNOSIS. THE FINDINGS FROM THE DRIVESHAFT SPECIALIST WERE QUITE ALARMING AND IT'S OBVIOUS KIA IS TRYING TO HIDE THE PROBLEM AND FORCING CUSTOMERS WITH THE SAME PROBLEM TO LIVE WITH IT. DRIVESHAFT SPECIALIST TOLD ME THIS PROBLEM WOULD GET WORSE AND AFFECT OTHER AREAS OF THE VEHICLE. I HAVE BEEN FOLLOWING A KIA FORUM AND THEY ARE LITERALLY HUNDREDS OF TELLURIDE AWD'S WITH THE SAME PROBLEM. YESTERDAY I TRADED MY VEHICLE OFF AT A $6K LOSS SO I DID NOT HAVE TO DEAL WITH THE HEADACHES AND KEEP FIGHTING KIA. THIS IS...

THERE IS A KNOWN ISSUE WITH TELLURIDES AND HYUNDAI PALISADE VEHICLES RIGHT NOW WITH EXCESSIVE VIBRATION WHEN SPEEDS REACH 55MPH - 70MPH. KIA CONSUMER ASSISTANCE AND DEALERS ARE NOT BEING HELPFUL. THEY ROAD FORCED BALANCED MY WHEELS AND SENT ME HOME...I TOLD THEM IT'S NOT FIXED AND NOW THEY WANT ME TO TAKE IT BACK. THERE ARE MULTIPLE PEOPLE ON FORUM/MESSAGING BOARD WITH THE SAME PROBLEM. KIA REPLACES DRIVESHAFTS/AWD COUPLERS ON SOME WHICH RESOLVES THE ISSUES BUT IGNORES OTHERS. THEY NEED A TSB TO FIX THIS UNIVERSALLY. THIS PIECEMEAL APPROACH HAS GOTTEN THEM IN TROUBLE WITH NHSTA ALREADY.

THE STEERING WHEEL AND SEATS VIBRATE WHILE DRIVING BETWEEN 60-80MPH. THIS IS A KNOWN ISSUE ON TELLURIDES AND PALISADES THAT IS FIXED BY REPLACING WITH A PROPERLY BALANCED DRIVESHAFT. HOWEVER THE DEALER REFUSES TO PROCEED AND KIA CONSUMER AFFAIRS HAS BEEN DIFFICULT TO WORK WITH.
