From what I've seen on these forums, with good maintenance the most common major failure is the hybrid battery, usually between 150-250k (age factors into this greatly - if you can put 300k on a Prius in 5 years, the battery will likely last, but a 2004 model with only 120k is still likely to fail).
But your Prius’ battery will only run optimally for so long, and it’s important to know the factors that can affect its lifespan. For starters, the distances you travel can affect your battery.

However, ten-year warranty periods of ten years or 150,000 miles of service are now the norm on some Japanese-made hybrids, one example being late-model Toyota Prius vehicles. Moreover, manufacturers in the U.S. domestic market are legally obliged to transfer and honor the balance of hybrid battery warranties. This requirement means that if you
