Yes, I was playing on the PC and the Mako was parked on a slope so that could be why. I did get strange things happen in places where the Mako would flip over or sometimes suddenly jump up if you tried to go up steep slopes or very rough terrain. Figured it was because I was trying to make it do something it could not handle...
I think that was the bigger prob I had with it. At first it was fun rock climbing in that thing, but the new wore off after the third planet. The scanning in ME2 makes it a little easier, but even that can be tedious after a while. But there has to be some type of exploration involved. I just think it should be done with a flying transport. A real flying trans, and not that hovercraft thing they tried came out with in ME2.
