2009 Lexus GS450h w/90500 miles. I enrolled full-time in college to reset life and parked my car to save money. The car previously gave me not a second of a problem... now I have a strange light on, only to be told that my high voltage battery needs replacing due to the lack of usage. Since the verdict, I try to drive the car at least weekly and notice the energy in the high voltage battery fluctuates but depletes when the car is idle. How long will the battery sustain at this rate? The dealership tried to scare me into trading, but not an option... they quoted a replacement for a high voltage battery at 9k. I found a battery online for 3k but cannot afford it at this time. Your help is really appreciated.
There's no saying how long it'll last but it's definitely going out that's the problem with hybrid cars even for three grand you're getting a rebuilt one that might last a year or two when you pay almost 10 you get a new one that's why I tell people not to buy hybrid cars in the first place they're very expensive to maintain as they age
