Nothing but the AGM accessory battery has failed on that car.
My wife's car, with 170K, still has the factory original flooded Honda battery that is now 8 years old........
I had motor mounts fail on my Prius, within about a year of purchase. Also, it has more rattles and clicks than I like.
FYI, my battery failed at about 80k miles. Other than buying at the Toyota dealer, the only 3rd party replacement that I found was an Optima battery ($147 at streetsideauto.com
with free shipping).
If you find a lower price replacement, even flooded, let me know because I will need to replace my wife's Prius battery. However, note that the battery should have the little tube outlet for venting hydrogen out of the passenger area. The Optima does have that.
