Thanks Lee , sadly the HHC was passed well over 1 year ago. " expect the worst -you will never be dissapointed ! "

good idea John , In hindsight , I wished I had tested that before the flat-bed took it away, but like I mentioned at the beginning of this topic, I am green to Hybrids and didn't want to mess with anything, for fear of making it worse.

John , thanks, Lexus checked my car's history, and said as it hasn't been serviced by a main dealer in the last 5 years, and hasn't had the aforementioned HHC, the Hybrid battery "may not" be covered.He seemed supportive, and indicated that all is not lost..............we shall $$$see !

Peter , thanks, it's the Hybrid battery. sorry , totally new to Hybrids, my 11 previous cars were "old-school" !

Thanks John for your replies, Yes , I realize how expensive this fix could/will be. My local garage did it's mot & service, but as they are not Hybrid - trained , they couldn't do the Hybrid Health check, and the car is 11 yrs. old without warranty...will have to see what Lexus discover in the diagnostics. Thanks again.

Hello everyone, my first posting here , so hope I get the format right ! Yesterday , after several years of fault-free driving of my GS450h , the engine management light came on, but the car continued normally. I drove it for 30mins. Several hours later , it started ok , everything appeared normal ( apart from the said engine mgmnt light) ,Then I heard an odd noise from the boot, and the exclamation triangle came on with the associated "check hybrid system" warning message. On the Energy/Consumption middle main display- 3 blue bars were indicated, flow arrows were moving around the engine/battery/electric motor/axles as normal, apart from no directional arrows out of the battery .I pulled over. Nothing appeared untoward at the battery site, or the other control box areas in the boot. I continued for 20 mins. 3 bars became 4 - then 1 ..... panic ! then the dash lit up like a xmas tree ! - engine died on me . A road-side recovery guy put diagnostics on it and said "the battery is not keeping its charge -it must be the alternator " - This car , I believe doesn't have one ! ??? Many other faults came up -not surprising as hardly any juice in the battery....I have sent it to my local Lexus$$$$ dealer , any thoughts ?? new battery ?? Thanks for taking the time to read this.
