NHTSA Complaint #11430861 — 2009 VOLKSWAGEN JETTA

this is the third time i've had issues with the power steering briefly failing on this car. The first time, several years ago, it was related to the ABS recall, and it was replaced. It also failed when the alternator was going bad. Now the steering light flashes, it makes a beeping sound and the power steering fails briefly. It's not showing codes. I see from reading the vw TDI forums that this is fairly common problem. It's very frightening and I think there needs to be some kind of backup system on these cars so that the steering doesn't fail, potentially causing a lethal accident, whenever some related sensor goes out. Shouldn't they be completely separate ? Thank you
