Another item to consider is the design of the battery pack. Ford's design is to use row upon row of D Cell sized battery cells. If a cell or cells go bad all you have to do is replace the individual cells, not the entire battery pack.
 
Sure batteries cells will degrade over time, and at some point it may be more practical t replace all the cells (or most of them) with new fresh cells for optimum performance, but the point is it's your choice and you don't have to if you don't want to.
 
Time will tell, as I have over 41,000 miles on my '06 which I got in May of 05' I'm going to hit the 100,000 mark long before I hit the 8 year mark I'll let you know.

"he HVBattery is warranteed for 100,000 or 8 years minimum and the 8 year history of the Prius indicates they will last much longer"
 
I think the jury is still out on that one. There have been reports of high repair costs on some of the Gen 1 hybrids. The Gen 2s have only been out since 2004.

yes, everyone agrees that repairing/replacing the traction battery component is expensive.....(at this moment in time)
......the point is, what has been the failure rate?, how many batteries have failed and why? did the design really change substantially between Gen1(2) and Gen2(3)?
 
If the basic NiMH concept was flawed.....we would have seen a much higher rate of failure as the Prius design reaches 8, 9, 10 years old. I think a jury verdict doesn't need to wait until the design is 15 years old to decide if the NiMH HV Traction battery has a useful life that is comparable to other automobile components.

I wasn't speaking of just the batteries, but rather of all repairs associated with the hybrid propulsion system. In particular, the multifunction displays have had some issues. The hybrids are very complex vehicles, even compared with today's more complicated ICE only vehicles.

Yeah, I spoke to a friend last weekend who had a first gen Prius. 2 years ago it broke down (he didn't explain what happened). To fix it would have been $9000. So he just bought a new Prius. Not sure how 'economical' this was.

the same effect it has had on all of my non-hybrid vehicles....it reduces FE by a few gallons or more....

Cold weather makes almost all components run inefficiently. All fluids (engine oil, brake oil, tran oil, steering oil, engine coolant, etc) become more heavier at low temperature than at normal temperature because fluid density changes with temperature. Therefore, initially, engine runs at higher rpm to warm up powertrain and catalytic converter at expense of fuel economy. The engine rpm will drop as coolant temperature reaches preset temperature (~70 C). The only way to save some fuel in winter is to park car in the garage over night.

2008 Ford Escape Hybrid Mileage Not Good by jstelter
Jan 12, 2008 (6:30 pm)

I recently purchased a new 2008 Escape Hybrid. After 2 month of driving, I am greatly disappointed with the gas mileage. I have tracked my gas purchases, noted the mileage, and the average mpg is only 23.6 mpg. This average is for essentially in town driving. I live in Illinois and it currently is winter. But to lose over 30% of the stated "in-town" mileage estimate is unacceptable. Furthermore, I drive the car like an 'old lady', ie: slow acceleration, coasting to stop signs, etc...
 
I am planning on having the vehicle checked out by the dealer. My next step will be sending a formal complaint to the Regional Manager for Ford.
 
Anyone else having a similar experience? Be careful if you are considering buying this vehicle.

Your mileage my vary but I'm still averaging just under 29 mpg (after the metric to US conversion) up here in the wintery Rocky Mountains of Alberta -- this despite cold temperatures, reasonable amounts of snow and/or ice and the occasional use of my heated seats or defroster.
 
Have also reduced fuel inefficient items such as the roof rack cross bars, interior cargo cover (quite heavy) and other unnecessary items.
