Computer Failure problems of the 2018 Jeep Wrangler

This is the second time the vehicle has experienced a total computer failure while it was being driven. My fiance' was driving this time and lost power steering, brake assist, as well as the ability to shift gears or even turn off the engine. As before, indications are a complete failure of the can network - multiple cels and error messages, from fuel low to tpms fail to electronic start stop disabled to check shiftier, as well as a loss of power steering and the engine going into limp mode. The first time this happened I was doing 70mph on the freeway. It occurred at night, thankfully, as it caused me to swerve between lanes during the sudden loss of power/steering assist. If it had been during rush hour, I would have hit another vehicle. This time the computer failed while in a parking garage. Thankfully it occurred after turning into a straight away as my fiance' took the entire length to stop due to the loss of breaking; she blew through a pedestrian walkway and could not stop and, if it had happened during a turn, she most likely would have hit a car or hit the edge of the parking garage. Both times we were very lucky that we did not have an accident that resulted in major damage or a fatality. Jeep has found 2 electrical wiring problems so far with this Jeep and obviously there are additional wiring defects present in the vehicle.
