Hey guys, just a update here.
I went back to Tesla service center today and they finally found the problem.
The problem was the driver’s seat sensor.
The car thinks theres always someone sitting down.
Seat belt alert was always on. The technician showed me a trick. When you punch the seat a few times the sensor deactivates then everything works perfect even the walk away lock.
They created a work order for a new seat it should arrive in approx one week.
