Prius Hybrid



they are EXCEPTIONALLY reliable by battery standards - the batteries will probably last around 10 yrs..the problem is that cars last more than 10 yrs (decent ones)..every prius in its lifetime should se 1-2 battery set replacements - and at the current costs for new ones, that's really tough to swallow.

recall that the prius hybrid hasn't been around long enough for the batts to start failing in large #s yet..give it another 3-4 yrs for the data to come in.

yes, today, that is true..but in 3-4 yrs, when the batts begin failing in large #s, that will change..my hope is for a nice aftermarket developer to get in the game with those batteries.

Fortunately, there are plenty of salvage batteries available for very good prices. Furthermore, battery technologies are improving and prices are going down. Also, there may be a fairly simple way to refubish battery packs by replacing electrolyte in marginal cells and rebuilding replacements. Think of it as the battery equivalent of rebuilding an engine. The technology is not that hard.
However, if you are risk adverse, just sell the car before the battery fails. Do let me know how much your asking.

Depending upon the price of gas, you may get it.

How do you come up with the estimate? Toyota has stated they chose the NiMH over LiIon because the NiMH has no specific life limitations. Like the Edison cell, they could theoretically last centuries. Theoretically, of course, because they are in a vehicle that tends to bump along the road. But so far (and the Prius has been sold for 10 years in Japan) the rise in battery failures that would signal trouble has not yet been seen.

hopefully you're right. but they warrant the battery for 8 yrs, makes me believe it has a 10-12yr life.

The basic warranty on the car is 3 years, so does that mean that the car has only a five to six year life? The engine and drive train are warranted for five years; does that mean that their lives are only seven to ten years?

no. but batteries have fairly predictable lives depending on cycles and ambient temp.....far different from knowing, when, for ex, a transaxle will crap out..

And that has absolutely *nothing* to do with the length of the warranty, despite your surmise that they are related to such a tight degree.

Oh, I almost forgot; in some states, the battery warranty is for 10 years. Does that mean that it has a 13 to 15 year life?

Isn't it amazing that the exact same battery can have different life spans based on local legislation? ;-)

However, she and many others here have a lot of group experience with the NiMH in the Prius application - empirical data trumps theory every time. Science, you know.
Some more you should know about the application: in operation the battery is forced air cooled with air from the passenger compartment. The handful of failures - representing around 0.1% of the Prius sold - and the associated DTCs to date suggest mechanical failure of connections within individual cells, and have not taken on any pattern related to years or miles in service. 2001 models in the US regularly make it to the 200K mile mark on the original hybrid battery. (Michelle et al know all this.) The smart way to bet is that few Prius cars will face battery replacement during their useful life. That has been the experience so far and I don't see any reason that should change.

What theory? He doesn't have a theory; he doesn't even have a hypothesis. He has mere speculation.

I'm suspecting that you're wrong. I'm also suspecting that you don't realize that the relationship between the length of a warranty and the expected product life is tenuous at best, if at all. best you keep quiet about this.

I agree completely. The 2001 and early 2002s had a handful of design problems (mostly covered by extended item-specific warranties now), while the later 2002s and the 2003s were really solid. The 2004 redesign introduced a few more problems that were addressed in the '05s and '06s. The '07s and on to the next redesign should be paragons of reliability. There will probably be lemons, but Toyota does a great job of keeping those to a minimum.
It's worth noting the 100K mile / 8 year hybrid system warranty for the benefit of those worrying about surprises in the hybrid system. Few people have had to take advantage of the hybrid system warranty.

You don't need to know how the hybrid system works. Just drive it! Remember to put gasoline in, and follow the regularly scheduled maintenance guide ( http://smg.toyotapartsandservice.com/ ), and you'll be fine.
Consumer Reports has continually placed the Prius in its top picks list for both a used car and the reliability lists. http://autos.msn.com/advice/CRArt.aspx?contentid@23544
powertrain is warrantied in the US for 5 years/60,000 miles. the hybrid system is warrantied in the US for 8 years/100,000 miles (which includes the hybrid battery pack). If you live in a CA-emissions state, the AT-PZEV Prius' hybrid battery pack is further warrantied out to 10 years/150,000 miles. Warranties are NOT pro-rated, but full coverage.
Remember that Toyota had the first production hybrid on the road - the Toyota Prius has been out in Japan since 1997 for the 1998 model year. It was first introduced internationally in 2000 for the 2001 model year. In 2003 (for the 2004 model year) the car underwent a redesign (compact sedan to the current midsize hatchback, a better hybrid system, etc.). Toyota has since put this newer hybrid system on the Harrier (Lexus RX400H), Kluger (Highlander Hybrid), Camry Hybrid, Lexus GS450H, Alphard Hybrid, and Estima Hybrids, with plans to put it into more models in future years.
You'll get way more information asking Toyota Prius owners: http://autos.groups.yahoo.com/group/toyota-prius / http://autos.groups.yahoo.com/group/Prius-2G / http://www.priusonline.com / http://www.priuschat.com /

the car is reliable with one flaw - it runs much of the time on batteries that have an 8yr, 100k mile warranty - after which replacement is around $7,000..so, if you can drive it for about 75k miles and sell it...........should be very reliable/economical.
