Power Steering Light On problems of the 2016 Jeep Cherokee

Vehicle loses power while driving, engine shuts down, steering locks and the dash lights up with a message that says put vehicle and "park" and then select desired gear. I have two small special needs children. This has happened 3 times in the last two months. I keep my vehicle up to date on maintenance/service. I read over 100 people's exact same complaints on line. It doesn't make sense that I am paying a car payment, have less than 45,000 miles on a less than 3 year old vehicle, and having these kind of safety concerns. We have one vehicle, limited means, and tons of therapy appointments. Today, my car died with no warning on a busy road, gives me approximately 10 seconds to pull to safety before there is no speed/ability to manuever the vehicle. It is ridiculous that the risk is so high, and the number of complaints listed on line show a serious issue with this among hundreds of vehicles by Jeep and nothing. The dealerships/service continue to make comments like "we were unable to replicate the issue". To be specific: driving at about 25 miles per hour, straight following a right turn. . . . Lost power. Lights went on the dash, message above appeared. It took two tries to restart to get me out of the middle of the road.
