Hi, Lexus family.

My RX kinda in good condition, but i started to notice that at low speeds 10-20Mph while I'm accelerating i hear the engines sound how its accelerating, but along with it i can hear another acceleration sound, like a sound of electric motor. its going along with the engines acceleration sound but kinda couple seconds behind.

What is that?

 

Mine makes a very slight whining noise from the speakers. Listen to the speakers to see if the noise is coming from there.

 

okey, i will check. but its kinda acceleration sound which going along with engine sound

 

your noise from your speakers is comin even if radio/Cd player is off?
