Maybe I have had to drive a lot of defective cars but in the 10 years as a driver 4 different cars I have owned have lost power steering ether momentarily or permanently and I never even worried about it.
If you cant safely operate a car without power steering or breaks, or you panic....I don’t know if you should be driving. No mechanical system is ever 100% reliable. Cars are designed to be operable with the loss of power to steering and breaks. It is just harder.
So you’re saying it’s fine with you that GM has a defective power steering system that they’ve recalled and replaced with non defective systems in some models but left the defective systems in other models?
