At around 107,000 miles, we started hearing griding/whining noises from the engine compartment. After multiple inspections from 3 different auto shops a Toyota dealership confirmed the transmission and transfer case had failed and needed to be completely replaced. There were NO warning lamps, messages or other symptoms besides the griding/whinig noise prior to the failure. After the Toyota dealership diagnosed the issue, we stopped using the vehicle until Toyota could make the necessary repairs for the vehicle to be safely driven. The Toyota dealership made the necessary repairs that we paid for on 10/28/25.
