I had a 2004 Honda Civic
I had a 2004 Honda Civic Hybrid and I've found the author's statements relating to the HCH to be 100% accurate. I cannot speak towards the Insight or Prius. When my hybrid battery started dying, the 12v lost its charge and the car would not start. I had to have the battery pack replaced around 115k miles at a cost of around $1800. The CVT needed to replaced at 95k miles - thankfully I had the extended warranty which covered that. I have a friend who also still has a 2005 HCH. Her CVT was replaced around 105k miles. When my second battery pack started failing again around 150k, I got rid of it and traded it towards a Chevy Volt, which has been an awesome vehicle.
