Do I have to pay for car repairs I didn't authorize?

Shops sometimes perform full repairs or replace extra parts without calling to provide a price or ask for permission first. This traps you with an unexpected bill you cannot afford, making it difficult to dispute the charges without ruining your relationship with a mechanic who knows where you live.
