I've been doing some research on the GS350 2007-2015 and a lot of customers state that their having BRAKING ISSUES,a lot of customers mentioned the BRAKE ACTUATORS,has anyone out here experienced any of these MAJOR BRAKING issues and I'm also wondering if this is the case why hasn't a CLASS ACTION LAWSUIT been brought against LEXUS, because as I've been reading LEXUS won't even properly fix the issue?????
