I own a gx470 ( bought 2 months ago 1200 miles )
Today while merging on a ramp, i noticed VSC ( both lights) came on as well as engine light.
I also noticed that the vehicle became sluggish as though it wouldn't move. I had to call roadside assistance and tow it back to the service centre. I will keep you posted. I sure hope no one here experienced anything similar.
