Mine is like that but I just ignored it. At 25000 miles, I have very few complaints about my 4Runner.
My biggest is the exhaust fumes through the rear window. I wish there was an easy fix (reroute the exhaust???).
I have a 2003 4Runner Sport (V6) and hear a "POPPING" sound when I make a sharp right hand turn (on the left side of the truck).
Is that the XREAS system or is something broken? Doesn't do it on left hand turns.
