2025 Chevrolet Silverado 1500 drivetrain & axles problems

My 2025 Certified Pre-owned, 10 day old truck with approx. 6200 miles, was parked and I was unable to shift into reverse (as if in neutral). I put the truck in drive and entered the highway. About half a mile later, multiple warning lights appeared and the truck slowed, unable to shift out of gear. Luckily, there was a dealership a few miles away so I drove the truck there slowly and on the shoulder as much as possible. Upon inspection at the dealership, they told me that the valve body needed to be replaced.

The contact owns a 2025 Chevrolet Silverado 1500. The contact stated that while driving at an undisclosed speed and attempting to accelerate, the vehicle was stalling. The message "Transmission Service" was displayed on the instrument panel. The dealer was contacted and diagnosed the failure as a shifter assembly failure. The vehicle was not repaired because the part was not available. The manufacturer was not made aware of the failure. The failure mileage was approximately 15,000.
