Same with me. Have 14k miles and yet to feel any buzzing or vibrations. Only at cold start, which is reasonable.I have a 19 RL... I've been paying attention, but i have yet to feel anything that feel like the VCM kicking in...?
If it is working, I cant feel it. At this point I'm assuming that they have worked the issues out.... I have no plans to muzzle unless I start feeling vibrations etc that can be tied to the VCM system.
