I have a 2 months old regular 12 V battery, but the same thing happened with my Lexus400h (TCGrace)
Check system, check hybrid system, check vsc system, check system etc. so I'm !Removed! off and regret to buy this POS.
I had a wonderful Nissan Altima 2003 brand new when we've purchased it. Just gave it to a friend with 288,000 miles still running well and never ever had to do anything with that great car, only change the oil, oil and air filter...
Lexus my A....
