Well the battery was dead again. So I guess you can now tell that I only use the Lexus on weekends. Most of the time I drive my supercharged bimmer. Anyway, took the battery to Autozone and waited for it to get tested. 15 minutes later, battery was SHOT. What after market battery would you guys recommend? I know it is still under warranty but If I have to pay a pro rated value, I might as well get an aftermarket battery. I'll find out for sure Monday when Bob Baker Lexus service department opens up.

 

Finally got the chance to take the GS300 to Bob Baker Lexus today. Testing resulted to a failed battery load test. After my first cup of coffee, battery was replaced for FREE with 18 month replacement warranty. Car was washed and I was back on the road in no time.
