The system that I believe to be failing has to do with electrical components of the 2017 Chevy Tahoe. It has completely lost all power two times while driving this vehicle. In both instances, mine & my children’s lives were at risk including those who could have hit us. If anyone had been behind me as I was turning and the car shut off mid turn, it’s possible we could have been hit by a vehicle(s) going 50+ mph. It’s available to you to be inspected if needed. The vehicle has been evaluated by a mechanic who says he cannot find any specific ‘problem’ but did have to turn off multiple error codes. The chevy dealership thinks it may have to do with the remote start antenna. This has not been reproduced by a dealer or service center but it has been reproduced by myself when I attempted to drive the car again after the error codes were turned off. I also have confirmation of this happening to another person who owns a 2017 suburban and after servicing the car they continue to have issues. They were entering onto a highway on the on ramp and their car completely lost power and stopped- I would hate to see what could have happened if this was on the highway itself as it could have had the potential of lives being lost. The only warning messages I have seen had to do with servicing the remote start, which has never worked for us despite having it worked on prior to purchasing the vehicle. There were messages about stabilitrack the first day this incident occurred but not the second time that it occurred. Both times the car will turn back on after about 5 minutes but it’s as if the cars system was completely reset (clock at 12, radio setting default, etc). The fact that I know of one person with a 2017 Chevy that this has also happened to, I believe an immediate recall should be initiated as I will not be driving this vehicle until there is an answer to save our lives and others on the road.
