NHTSA Complaint #11582675 — 2023 KIA TELLURIDE

I purchased a new 2023 telluride-SX in April 2023. For the first time since owning the vehicle, I used the Snow Mode during the snowstorm on 14 March 2024. I then used it again on 15 March 2024. I experienced a serious problem on both days. When I stopped at redlights, I tried to accelerate as I made a turn. I lost all power, and the car came to a near stop, nearly causing an accident by being rear-ended. I quickly switch to the Eco Mode and the power returned to the car. I took the car into Arapahoe KIA, CO service department on 8 April 2024 for an oil change/tire rotation AND to address the issue with the Snow Mode. The Technician said the issue I describe would happen if the snow was deep.(?) I explained that the roads were nearly bare. He then said that they would look at it. He later said that they could not duplicate the malfunction in the Snow Mode and to bring the car in if it happened again. The KIA service department is the only place that supposedly inspected the car for the issue described above. There were no warning lamps, or messages, or other symptoms of the problem prior to the failure.
