So I drove the prius from TX to Las Vegas and all of a sudden warning lights came on and the car died. It is 2010 with 7500 miles on it. After getting it to the dealer (it eventually restarted), I was told the water pump was kaput. They replaced it under warranty of course, but I was out my car for 3 days - they had to get the part in. I'm starting to worry if this car is a lemon. This may be premature, but what can I say. It has been in shop several times (due to weird rattles) and now this! Egads! Any thoughts/ideas?
