My 2011 GMC Terrain while driving 45 miles down road the lose of power light came on and the car immediately slowed down causing me to almost have a accident. The car would run but shake real badly. I stopped the car and turned off for 5min and restarted and was able to make it home but had to do this at least 3 times getting there. I don't know what is going on, but I do know I almost lost my life in the process. My car seems to burn aiot of oil too here lately, like its drinking water.
