The article fails to mention how well the battery packs still functioned up to the 218 and 341K marks, It'd be interesting to know if there was a 2, 3, 5? mpg drop in fuel mileage the last 10, 20, 50K miles etc...

Published failure rates by Toyota is 0.003% to date or 1 in 40,000 cars... By comparison, many cars exhibit a 1% failure rate of their automatic transmissions

With more than 100,000 Honda hybrids on the road, the automaker told Newsweek that fewer than 200 had a battery fail after the warranty expired. That’s a 0.002 likelihood. Toyota says its out-of-warranty battery replacement rate is 0.003 percent—or one out of 40,000 Priuses—for the second generation Prius.....

Far more Prius have been crashed and totalled than battery failures. Since Toyota has a bounty on the batteries, they have far more returned batteries than needed for failures.. They have had for decades remanufacturing programs with certified and warranty quality for expensive parts available through the dealer network e.g. engines, transmissions, starters, alternators, air conditioning compressors, etc. Those parts are available at far less cost than new from factory parts.. I've bought a few over the years for my long out of warranty Toyotas e.g. 220-270K mile vehicles... They have a similar program for traction batteries...
