I sold my prius, but i'm not leavin.

not really love it (altho I do love my legend), more like I've grown to accept it......when my traction battery goes (out of warranty of course), I'll take it on the chin and pay for its replacement....

 

One thing I looked at when i bought my prius is how much used parts were on ebay and car-parts.com that usually tells you how often they break or just wear out. I was pleased to find that used traction batteries, inverters, transmissions and pretty much every other part for a gen 2 prius is dirt cheap this tells me that the prius is very reliable and as long as you can find one that has been well cared for it will last a long time. I hate to tell you this but you kia is worth half what you owe the second you drive it off the lot the prius on the other hand GAINS value as fuel prices go up and hold their value period. To me I'd rather own a vehicle that holds its value and take the risk that something might break rather than taking a huge hit in the wallet the second I drive it off the lot.

 

OPs decision was motivated by anxiety rather than statistics, but that can be said about anyone who buys a warranty.

Prius has a remarkable hedge against nasty dealer costs: PriusChat! EVERYBODY who is cost averse in car ownership is wise to learn how to maintain the car for healthy long life and DIY simple repairs. That in conjunction with independent shops for the rare inverter or battery repair/replacement makes the car, as Corwyn points out, the frugal car.

Eating depreciation on trade-in every 100k miles when a warranty runs out is not a smart money move.

BTW, if anybody is interested, the 10yr/100k warranty OP mentioned is a limited powertrain one. Details are here: http://www.summitplacekia.com/images/pdf/2011_warranty.pdf
And frankly, worrying about rare expensive future repairs in a Prius but buying a car with sub-standard safety features and crash test results would not be my first choice in ways to limit my anxiety.
