I have a 2006 GX470. After stopping at a light/stop sign etc, I feel a jerk. It usually happens when the A/C is on but I have occassionally felt it with it off. It does not happen all the time but happens enough to be concerned. I have the drive train warranty still left but not sure if that is my issue. Is it an engine issue, a/c issue or possibly a brake issue since the it will do this occasionally without the a/c on? Any suggestions would be appreciated.
Thanks
John
