Our Traverse has had this problem mainly on the highway but it has also happened on our gravel road going 30 mph. The Traverse will all of a sudden display "engine power is reduced, it will say service traction control, service stabilitrak, traction control off. " during one of the times, it happened the steering column also locked up. The engine shakes enough that it makes the muffler shake when this happens. The dealership claimed they found a memo from gm on how to solve the problem. We just spent $690 to get a new fuse block and terminal installed. Supposedly there had been water damage/corrosion. Our Traverse has never been submerged in water. This problem is very dangerous and Chevrolet needs to be held responsible. Having our vehicle all of a sudden reduce power has lead to several almost accidents, especially when the steering also locked. This problem is very similar to a problem described in recall 14515 which did include 2009-2014 Traverses. According to Chevrolet my VIN is not part of that recall. I think this issue is similar to the recall but different.
