2021 Kia Telluride Transmission 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 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.

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.

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 .

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

I drove my brand new telluride off the lot with approximately 12 miles on it. About a month after having it I noticed the following: when entering a highway from about 20-25 MPH, the vehicle would not gradually accelerate allowing me to enter the highway. As I continue to press the accelerator pedal the rpms would eventually jump up and the vehicle would launch itself forward.

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.

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.

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.

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 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.
