Not alway, sometime the Censor wire right next to Rotor get old and weak can cause the light Symbol pop up, but before doing anything else, Please check your tire presure just like brother above mention. i have 2008 Yukon Denali Sporty. once in a while i saw this light pop up, but all i do is, just hit the reset botton that's all. and the light will disppear... Oh by the way, this is very good advice......
