At what mileage does the timing belt need to be changed?

stay the hell away from P-TUNE!!!!!!YOUR CAR HAS A TIMING CHAIN,NOT A BELT.if it's the 2.4L......NOW if it is the 3.5L 6 cylinder,then yes it does have a timing belt and should be replaced at 105,000 miles normal driving conditions and 60,000 miles in severe dusty driving conditions.THE TIMING CHAIN ON THE 2.4L 4 CYLINDER SHOULD LAST THE LIFE OF THE CAR,UNLESS RATTLING,MAKING NOISE OR BREAKS!!BUT DON'T LET P-TUNE TOUCH IT!!!if they told you that your 4 cylinder,2.4L 2009 accord needs a timing BELT,then what is wrong with this picture?STAY AWAY FROM P-TUNE!! if your car is running good and the check engine light is not on,then you don't need to take it to Autozone or anywhere else.just drive it.
