3008 Allure 2019 Model Gearbox Failure

While parking the vehicle in the morning, the gearbox malfunction gave a warning to get the vehicle repaired.

I stopped the car and started it again.

I extended my warranty for 2 more years with 50.000Km.

Can this malfunction be taken care of under warranty in the vehicle 40,000?

Also, there is no sound coming from the rear speaker in my vehicle. Is this fault also covered by the warranty?
