I have a brand new 2017 Traverse that has less than 3000 miles. When I'm on the freeway and use the cruise control the warning light for traction control comes on and says it needs service. Then it proceeds to leapfrogging so bad that I have to pull over and shut it off. I have had it in to the dealership and they said it is a sensor and supposedly repaired it and sent us on our way. The very next day it did the same thing. NOT fixed!! I'm concerned that this is a recall worthy problem after reading all these similar situations. Worries me to be on the hwy and having this out of control problem. Going back this week to the dealership that is forty miles away. Inconvenient when I have a low mileage lease.
