This vehicle is unsafe due to a violent side to side wobble in the front end much like the Jeep death wobble. This happens constantly anywhere from 30mph - 70mph usually after hitting a small bump or when turning hard. The turning aspect is where it has become very dangerous on slippery surfaces as the car then slides out. I live in the mountains where this is a normal occurance. I am actually afraid to drive this vehicle any longer. The dealers have confirmed the issue, but states that GM does not have a fix for this as of now. I have heard this is affecting only the AWD Terrains and equinox platforms. GM has been unresponsive trying to get an answer or getting this fixed. The car has been into multiple dealerships several times for this same issue and has been happening since the car turned about 2400 miles and has been happening more frequently since then for the past 6000 miles.
