2025 Kia Telluride Transmission Problems

Your 2025 Kia Telluride's transmission failed to hold the vehicle in Park when parked on an incline at just 3,903 miles, causing the car to roll freely despite the gear being engaged. The parking pawl (the mechanism that locks the transmission) was activating but not actually securing the vehicle, creating a risk of unintended movement. The dealership verified the problem during a test drive and determined the issue was internal to the transmission; a complete transmission replacement was needed to fix it.

Issue: Engine stall & loud tapping/grinding noise Vehicle only has 1,100 miles and has stalled about 5 times when slowing down to about 10mph & then accelerating again. Issue has also happened when going about 3mph & then accelerating. About 10sec stall & then vehicle takes off. Several of the stalls happened even though the Auto/Start switch was engaged to disable feature since I thought maybe a bad switch was the issue causing the stalls, but stalling happens with it on & off. Another issue engine makes a tapping noise when in gear & accelerating up to about 1200rpm. Issue has been getting louder since purchase. At 1100 miles started car & pulled into garage after vehicle set for about 2hours (75F outside), upon doing this the engine sounded terrible like there were a handful of marbles in the engine, super loud sound, at this point made appointment with dealer, but they are so backed up vehicle can't go in for service for about 2 weeks per no loaner car available until then, since it can take up to 1 week to get looked at. Will update with their findings but looking at form pages & You-tube videos it seems like the ongoing engine tapping complaint resulting in an engine replacement & maybe part of the 2024 recall Valve Spring breaking resulting in the loud marble sound I am hearing. Car stalling is a major safety concern since a few of the stalls happened when pulling in front of traffic going 60mph.
