NHTSA Complaint #11466857 — 2018 CHEVROLET TAHOE

My wife was driving everything was working fine until a message came on the dash "steering stopped Drive with care" she was mid way in a turn to get on highway when this happened if I wasn't in vehicle to grab the wheel my wife would have ended up in a wall or worst case in the canal next to 95 with my 4 year old in the car. The vehicle is currently at a chevorlet dealer in Greenacres Florida and they say the electric steering gear has stopped working.. this seams like a very unsafe system as when it stops the steering wheel is very stiff more than a old car with no power steering. I think this needs to be investigated yesterday as someone could die from this if it hasn't happened already. As of right now I no longer feel that this is a safe vehicle for my wife to be driving
