2024 Kia Telluride Powertrain & Transmission Problems

Summary of Defect and Repair History My 2024 Kia Telluride EX AWD has experienced repeated and ongoing transmission failures. The failures include the vehicle becoming stuck in 5th gear, unsafe acceleration characteristics, and loss of normal drivability. Two transmissions have been replaced, and the same defect continues to occur. The vehicle remains at the dealership today with the defect unresolved. Repair Attempts and Days Out of Service 1 Transmission replacement 30 days Returned but defect recurred. A warning lamp (check engine) did illumiinate after the first transmission failure, however did not for the second nor third failure. Failure was confirmed by Kia dealership. 2 Transmission replacement 47 days. Returned but defect recurred. Failure was confirmed by Kia dealership. 3 Current repair attempt 24+ Not repaired. The vehicle has incurred three repair attempts and 101+ days out of service for the same defect. Failure was confirmed by Kia dealership. Substantial Impairment: Use, Value, and Safety 1. Impairment of Use  The vehicle has been in the dealership’s possession for more than three months in 2025, making it unavailable for normal use  Driving attempts prior to service demonstrated lack of shifting, hesitation, clunking, and unsafe behavior  The defect continues to occur despite repeated major repairs 2. Impairment of Value  A newer model vehicle requiring two full transmission replacement in one year and still malfunctioning has demonstrably reduced value  Transmission replacement history is discoverable and materially reduces market value 3. Impairment of Safety  Transmission failure compromises safe acceleration, speed regulation, and predictable power delivery  The failures occurred at low mileage, indicating a systemic nonconformity rather than normal wear, presenting an ongoing risk As a engineer with 20+ years of experience, I do believe the root cause is a wiring issue (e.g. shorted wiring harness), not a transmission failure.

The vehicle was parked(placed in park on gear shift) in a friends driveway, facing upward on approx. 15Deg incline with the engine idling. My wife exited the vehicle and walked around the front of the vehicle to the houses front entrance where she spoke briefly with the owner inside the front door. On leaving the house the car was gone from where it was left parked. My wife found that it had rolled up the driveway incline until it hit a couple of pine trees at the top end of the drive and stopped. She opened the door and found the gear shift still in the parked position at which point she entered the car, placed it in reverse and backed out of the tree branches and took photos. The incident was immediately reported to KIA America and the dealer. The vehicle has been at the dealer for 3 weeks now with no resolution, undergoing "testing". They say it is not operating the way it should be, but they have not been able to identify or correct the issue. KIA America has told me the issue has been elevated to KIA factory tech support. Other than scratches there appears to be no major damage. Photos show driveway, trees that stopped the vehicle and debris and scratches.

Transmission constantly slipping after driving and transmission gets warmed up. Vehicle continues to rev up and enter high RPMS before changing gears and then jolts the vehicle as changing gears. Also steadily leaking coolant fluids, have taken vehicle to the dealership as of now THREE times to have the coolant issue serviced. Repairs are still not complete to date.

When you are stuck in the snow and start to spin, the AWD kicks out and you cannot move. Very big issue for anyone that lives in an area that snow accumulates.

Vehicle was part of the NHTSA 24V077 recall for faulty valve springs and took into dealership in April 2024 and engine was not replaced as it was listed as ok. Subsequently took for other recalls and maintenance, each time the vehicle was released back. Took vehicle in for oil change in Apr 2025 and stated evidence of noise in rear end, repair records indicate spare tire loose so tightened and given back. Noise was still evident so I tightened and in mid August, noise got worse and could feel while driving. Took in 29 Aug 2025 for oil change and mentioned noise. At this point after 6 or more visits, Kia flagged the vehicle under 24V077 and directed engine change saying unsafe to drive. So they allowed me to drive 30K miles and finally replaced engine which was performing satisfactory. The rear end noise was determined to be rear differential which was replaced, noise remained, techline case opened, shocks changed, noise remained, Field engineer visit scheduled 6 weeks out then canceled with direction to change rear cross member which was changed, noise still there. Now existing case re-opened with request for another engineer to visit. More money spent in rear end repairs which noise started in April 2025, then the cost of engine replacement which has only 65 miles all by dealership. Vehicle at dealership since 29 August 2025. Not confident engine replacement is satisfactory as fuel pump also required replacement and the inability to fix rear end is keeping from checking engine replacement is fixed. Wife no longer feels safe ever driving this vehicle again. Furthermore, Kia put us at risk by failing to direct dealership to change engine in April 2024 and all subsequent visits before finally flagging. My guess is lack of new engines available and did not want me to wait so allowed us to continue to drive extra miles and addl time took out of state Lemon Law timeframe likely. All repair records avail on request. Demanding buyback from Kia of America

We bought a 2024 Kia Telluride and had it literally 2 weeks long with about 684 miles. My husband and I were driving on a major highway and suddenly we hear a noise and engine line pops up on screen. Car proceeds to literally shut off, the wheel locked up, and we barely made it to shoulder of highway. This was huge safety issue, we had cars honking and speeding by us at 70+. We called the Kia roadside assistance who didn’t get a tow truck there till 3 hours later. We don’t have anything paper wise yet from the service department . They called and said engine was seized and needing replacement. We are very concerned about getting new engine that could potentially do this again.
