GS450h unanswered questions battery life
#32
I thought I should add a note to this thread - I had to replace the hybrid battery in my recently purchased GS450h at 88,000 miles. It sat unused for 4 months on a car sales lot due to COVID and both batteries seemed to suffer as a result. Lexus does warn about this in the manuals. I guess, as with all batteries, that long periods without usage (and the inevitable slow discharge) will kill them. I was hoping that some usage would help the hybrid battery recover but after two weeks I was still getting P0a80 codes frequently.

For a traction battery to become so low it cannot start the car, assuming the 12v battery has enough juice, the dealer has a special charger to charge the traction battery. If the cells are not balanced within a certain range it could be why they replaced it. Other companies can load balance them or at least try to. Dealers only want to sell things new.

It is a 2010 so it was on me. I went with the Green Bean as it has a transferable lifetime warranty. Several months later the car is running well so no complaints now my pocketbook has recovered!

It was $2400. I found several other options that were cheaper and seriously considered replacing individual modules myself. But in the end, the warranty seemed to be worth the extra outlay. It was a tough call though as I found an option for $1700 but only 6 months warranty.

In Singapore's tropical heat, hybrid batteries fail much faster. My 2009 GS450h had its first hybrid battery replacement in 2014 at around 50,000 km ie age 5 years(previous owner) and again this year 2020 at age 11 at 115000 km.
I've owned it since 2014. It's worth it for me to replace the battery since buying a brand new car with the same hp and features would cost me around 260,000 USD with Singapore added taxes and GST.
