GMC Sierra 2500 Mirrors

These mirrors vibrate with the slightest of bumps on the road, and seem to exaggerate them, making it very unsafe for driving of any sort. Getting onto a highway and merging with traffic was a challenge as the cars behind me bounced up and down, causing it to be difficult to guage their distance and speed. Absolutely horrible. The mirror has a warp to it as you get near the edges, so it is not completely flat. The motor to control it to the left doesn't seem to go far enough, whereas moving it inward to the right goes further than needed, almost becoming a vanity mirror for looking at oneself. That's a bit of a stretch, but my point is that it's useless to have it go so far inwards, when it stops at a point that is almost not far enough outwards.
