Re: Hybrid battery failure
I'm surprised at hearing about your early traction battery failure at 78,000 miles. Your Camry warranty and maintenance guide should tell you the warranty on your battery. The new one is guaranteed for a year from toyota. If you were 2 or more years till the original warranty is up, then the new battery will be warrantied for that period of time.
Your service-person should be able to give you the exacting details.
The hybrid system for the '12 TCH shows 96 months or 100,000 miles whichever comes first. California warranties the traction battery for 120 months or 150,000 miles.
The powertrain, engine, transmission and axles are warrantied for 60 months or 60K miles.
I have heard of used toyota traction batteries on Ebay for $300 to $500. Some fellow has a business rebuilding traction batteries by replacing the few weak cells and then repeated testing to make sure of it's overall quality. His batteries cost about $1850 exchange and come with a years warranty.
