2019 AUDI SQ5 Steering Problems

First, the tail lights malfunctioned randomly. Both tail lights were out due to some software error that eventually resolved after a week. Thankfully this was covered by Audi, and there is a redundant tail light system in place. The error just suddenly came up and all main tail lights and turning signals failed. This could have ended terribly as i was driving at night. An additional issue is the power steering also randomly failed. This is probably my biggest issue so far. The vehicle has 37k miles, and the power steering randomly went out while driving. This could have been catastrophic if i wasnt on a small road. In winter this could have easily caused a crash either to the terrain around me or another motorist. Issue has been diagnosed as electronic steering rack failure. For both these issues there were 0 symptoms just a sudden loss.
