Transmission Shudder problems of the 2023 Kia Motor Telluride

My 2023 kia Telluride sx prestige x-pro is experiencing multiple powertrain and safety defects beginning at approximately 48,000 miles. The vehicle is well maintained per the manufacturer schedule. Issue 1 - transmission shudder: the vehicle has a pronounced shudder and stuttering through the drivetrain during normal driving, especially under acceleration and load. This began at approximately 48,000 miles and has progressively worsened. Symptoms are consistent with torque converter clutch failure documented under kia TSB 089 (dtc p0741) and service action sa490. Issue 2 - intermittent limp mode (safety hazard): on multiple occasions the vehicle enters limp mode without any warning while being driven on public roads. When this occurs the accelerator becomes unresponsive beyond approximately 30 mph. The vehicle cannot accelerate regardless of throttle input. The only way to restore normal operation is to pull over, shut the engine off, and restart. This creates an extremely dangerous condition on highways, during merging, and in heavy traffic. My wife is the primary driver and no longer feels safe operating the vehicle. Issue 3 - instrument panel blackout: the instrument cluster intermittently goes completely dark while driving, leaving the driver with no access to speed, fuel level, warning indicators, or turn signals. This vehicle also has multiple open safety recalls including sc296 (engine valve springs/fire risk), sc303 (intermediate shaft/loss of drive), sc316 (power seat motor/fire risk), and sc347 (door trim delamination). A recent emissions recall was also received. Problems first reported at approximately 48,000 miles. Current mileage is 86,793. A case is being opened with kia consumer assistance and warranty service has been requested at the purchasing dealer. The vehicle is within the 10-year/100,000-mile powertrain warranty.
