Warranty Hybrid components Prius III

Hello Prius Fans I’m very interested in the new PIII. But I’m a bit scared off now. The new warranty services in Switzerland for the hybrid components are only 100’000km or 5years, with the PII that was 160’000km and 8 years. That’s almost a third less warranty time. What do you think? Was this shortened because the used components are mature, which I can not imagine, or after 5years there were some problems with the PII with which T oyota can then earn more money in the future? Greetings Roger
