StabiliTrack - Losing Power
 

Our 2015 Chevrolet Tahoe has off spontaneously flashed a StabiliTrack warning in the midst of all electronics flashing and will lose power. Literally happened to me over the weekend with my family in the vehicle driving 70 mph down the highway at night. Please HELP!

Welcome to the forum,
There can be many causes of the Stabili-Track error and the vehicle going into "limp mode" GM built in the limp mode so that the vehicle can still be driven at a slower speed to get you to a safe(r) place, the alternative is to have the vehicle completely shut down, no one wants that.
Get the vehicle scanned for codes, the generic response of the Stabili-track could be any number of items from a throttle body, to a throttle position sensor in the accelerator pedal... Get the the codes and we can address from there.

The dealership has had the vehicle for a week now and claim the car is not giving a code. So although the car did this on 5 separate occasions, the car is not recognizing any codes. Its as if it is a hard reset button happens.
