Radio/tape Cd Player problems of the 2018 Toyota RAV4

Not soon after I leased my Rav4 the brakes started grinding as if I needed new brakes & everytime I went in for maintenance they said nothing is wrong with them & they look fine. The rotors are rusted just on the inner part on both rear rotors & my car is garaged so there isnt any reason why they should be grinding or squealing. It makes the noise when I'm in motion. Also the radio stations are complete static & I have had 2 different Toyota dealers look at it & they say nothing is wrong with the wiring but can't figure out why all my stations come in statically.

The line departure alert / steering assist buzzer is not working or not loud enough to be heard. Occasionally when driving for hours on freeways I may get drowsy, so I bought the new Rav4 and specifically chose a model with lda/sa hoping that it assists me. After driving over 1000 miles between the cities, I am completely disappointed with this feature. It supposed to alert me when the car drives over the lines with a buzzer and gentle nudge to the steering wheel. I cannot hear the buzzer and feel any action on the steering wheel. I went to the culver city Toyota dealer two times in attempting to have this problem fixed. Both times I have been told that the system works as designed. During a test drive with the master technician, with radio off, at speed less 50mph, so with the minimal road noise, I could not hear the buzzer. I do clearly hear the buzzer of the parking sonar or pre-collision warning. So this is at best useless feature, at worst it is a distraction when trying to make it work at a highway.
