I've been ignoring the check engine light on my 2001 Prius for awhile, because I've had to pay too much too often for not screwing my gas cap on tightly enough, and assumed that was the problem again. But, the news is far more ominous. Though the car works perfectly, the dealer tells me that I need a new computer, which runs over $2700. I've got 106,000 miles on my darling car, and haven't had to spend much beyond many tires and basic maintenance, so maybe I shouldn't be so stunned, but I am. I was aware that I might have to cough up for a new battery at some point, but hadn't planned on this. Any counsel? Since I'm not seeing any trouble so far, can I keep driving for a few more days, weeks, months? What do I have to watch out for? The mechanic says one day it just won't start. Has anyone have this problem? Money might be easier to come by in a few months, so I'd sure like to wait, but don't want to be stranded somewhere away from home.
