2021 Kia Telluride: complete transmission failure

Filed Sep 21, 2026 · Engine, Transmission · OH

I purchased my 2021 Kia Telluride S new, with only 22 miles from the test drive. XXX (approx. 53,000 miles, vehicle age 18 months): The transmission failed while I was traveling approx. 75-80 mph on a major highway in [XXX]. Upon failure, the vehicle suddenly lurched as if the brakes had locked or the parking brake had been applied, nearly causing us to strike our heads on the dashboard and creating a hazardous situation for other traffic. After the failure, the vehicle would only operate in approx. first through third gears and reverse, and would not exceed 25 mph. We were forced to limp the vehicle off a busy six-lane highway. XXX: Due to parts delays, the vehicle was not returned until November 2022 after the transmission work. XXX (approx. four months later): The vehicle developed engine knock and excessive oil consumption. Advised this may have been related to oil degradation while the vehicle sat waiting for parts. Since then, I had to regularly check and add oil between oil changes. Despite low oil levels, no oil pressure warning light ever appeared. XXX (exact date unknown): While opening the sunroof at a stop, a loud crack occurred and pieces of the sunroof track, plastic and metal, fell onto me and my passenger. The glass is intact but became partially stuck open without the track to guide it. XXX: The engine knock worsened and became a squeal while driving approx. 60 mph. The vehicle lost power, requiring me to turn on hazards and coast off to avoid accident. Dealership mechanic advised that the engine had thrown a rod and blown the oil filter housing gasket. The vehicle is currently at the dealership and available for inspection. Kia has denied coverage despite the failure of a component linked to excessive oil loss and a recently extended 180,000-mile warranty, even after the engine threw a rod following a sudden loss of oil pressure. The failed transmission has likely already been disposed of. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

After receiving a Kia‑issued transmission control module (TCM) software update, my 2021 Kia Telluride experienced a severe and dangerous transmission malfunction while descending a high mountain pass in Colorado. When I attempted to downshift for engine braking, 3rd gear completely disengaged, causing the vehicle to accelerate uncontrollably downhill. None of the lower gears would engage or hold as they had prior to the software update. This forced me to slam on the brakes and ride them continuously down the mountain, creating a serious loss‑of‑control hazard and risk of brake failure. Downshifting is essential for safe descent on steep grades, and the vehicle’s inability to do so created an extremely dangerous situation. The issue was duplicated by the Kia dealership technicians, and Kia field engineers have confirmed awareness of the problem. Despite this, Kia Corporate refuses to authorize transmission replacement or reversal of the software update, leaving the vehicle in an unsafe condition. This is a critical safety defect involving gear disengagement, loss of engine braking, unintended acceleration, and brake‑dependent descent control. The vehicle is unsafe to operate on mountain roads, and Kia has declined to perform the necessary repairs.

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.

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.

Had a new transmission installed in February 2022. Now, beginning March 13, warning lights come on to check blind spot and forward collision systems. About 10 seconds after the car lurches violently. This has happened at full speed on interstate which is a huge risk for injury/death. I have video of this phenomenon.
