"Maybe that is why Sanyo has limited supply..."
 
Check your facts. Sanyo doesn't supply HV battery for the Prius.
 
"If the batteries are that reliable then, I wonder why Toyota spent the extra money to make them modular, so they would only have to replace the failing module."
 
Panasonic EV made 7.2V modules to get around licensing lawsuits. Ovonic(I think) only license out NiMH technology to produce small cells. They reserve the right to make large cells for electric vehicle development. One way for Japanese battery manufacturers to get around is to make and sell small modules. Hybrid car manufacturers buy those modules and form a bigger pack. Ability to be able to replace bad modules is a side benefit from that lawsuit loop hole.

"Toyota makes great cars, and has BILLIONS of miles driven on their cars. If their engineers say 150K is a good lifespan for the battery pack, WHO ARE WE to doubt their engineering expertise?"
 
Some people do. They would question why anyone would spent extra for green technology, while for them, spending more $$ for performance is perfectly acceptable. They don't care what comes out of the tail pipe if certain type of engines make great low end torque. They question how long the battery pack would last but not how long the oil supply would last. They would question environment impact of the battery pack recycling but not the whole car itself. They don't question spending $$ for bigger and more powerful car either. They don't care realiability of a car as long as the car is more than they are used to. It is sad but true.

Once again I'd like clarification. Isn't the hybrid battery manufactured by PANASONIC and not SANYO for the PRIUS? Who makes Honda's battery? While we're at it. What about the FORD ESCAPE Hybrid? Also, isn't the mother company MITSUSHITA? (excuse the spelling)

This is one of the lawsuits that was settled to allow the use of the NiMH technology in hybrids.

Yes, you are correct. Refer to msg#81 for more info. You can visit below link for confirmation.

Yup. Ovonic filed the lawsuit anyway. I believe Panasonic EV could of fought it and won but it would delay Prius and other HSD car production. It was the best interest for Toyota to settle it ASAP. Maybe that's how Ovonic took the advantage of the unexpected 04 Prius demand.

"Lets get the facts right ..... The coverage IS 8 YEARS OR 100,000 MILES on the Hybrid Drivetrain."
 
I believe that Cailifornia mandated 10 years and 150,000 miles. 8/100K is the Toyota warranty.

That is the way I understand it. My question is if the car has a problem in CA at 125k miles. Will the State of CA force Toyota to fix it. The car is required to get AT-PZEV rating, that it maintains the same level of emissions for that 10 yr 150k miles. So if the battery or electric motor or ICE dies it will not maintain that emissions level.

Toyota will honor the warranty; it is part of the cost of doing business in California.
