I have a 2003 GX 470, and about a month after I had the dealer change the battery that went dead, my instrument panel started doing strange things. My tachometer will intermittently go out, and read "0". I can also sometimes hear a mechanical sound, like a clock winding in that area.
My warranty just expired about a month before this happened. any idea what it is and what it cost?
BTW, I'm normally a fan of Lexus reliability, but this vehicle has had a lot of problems.
