I am at least equally sure that is not the case. Until you can point to other batteries that last longer, you guess is baseless. And Toyota's history of making cars that last *way* beyond the nominal warranty should speak for itself. As to why, my guess is that Toyota prefers to grow its customer base rather than leach off the ones they have.
I'm going to follow this thread. As the owner of both a new 2015 and a 2006, my 2006 had a battery failure at 54,000 miles this year in March. I bought the car used in July, 2014 with 44,000 miles at a Toyota dealership. The dealership where I bought it was the same dealer who serviced it and sold it to it's original customer new in August of 2006. Mint condition, no dings on the side, no chips on the front, no scuffs, scrapes, or scratches. Headlights crystal clear, interior perfect for the tan color. No wear signs or stains whatsoever. It was like a brand new car. I was surprised the battery failed so early, and so was Toyota. So even though the car was literally just outside of the "years" part of the warranty, Toyota paid for half of the repair, and I had to fork over $1,300 last March. I was just happy they did what they did. I'm interested to see how my G3 will do. I'm at 1,400 miles now.
That is was a well looked after car, rather than an abused one. Though at the mileage I don't think an abused car was likely to fail.
Nonsense. The kids I see driving like idiots and road racing have very nice looking cars. It is part of their obsession with cars.
But this is a 9 year old car with only 54k miles. Sounds like it was looked after and doted over to me. I imagine the owner was retired, rather than in their early 20's
I'm not so sure that light, and/or intermittent use of the traction battery is a Rx for good health. And honestly, this thread is just one more example that shows that the battery is affected more by time than by miles. I will say though that now that OP has a new battery in what very well may be an otherwise pampered vehicle, he has a fine car to keep for the next decade.
Good story. I think you also qualify for a spot on my other thread about Toyota Goodwill Warranty discount cases: HV Battery Goodwill Warranty Listing - Toyota Prius USA | PriusChat
Yes, I just assumed that since it was in such great shape, and had such low miles (driven an average of 5,000 miles a year!) meant all would be well for a long time to come. But I think the battery was affected by the time aspect.
I have 2010 and I am super close to 100k, I did take an extended warranty that for 48,000 miles or four years will cover the battery completely but I don't think I'm in end up using it
