Enjoying my relatively new 06 V a lot. Still getting to know it. Found the power steering fluid low (about 1/2 way up the cold mark when hot). So a system that shouldn't leak is low, makes me worry - haven't had a chance to eyeball for leaks. Has anyone dealt with power steering leaks? Found just a couple stories on old threads. Second question, is the GM power steering fluid recommended anything special? Normally I wouldn't have even thought about that, but then there is DEXCOOL...
