I have had no hybrid issues with my GS or the Prius that it replaced. The Prius I had for 10 years 128,000 miles, and in that time the total repairs amounted to one front wheel bearing. The Prius uses exactly the same battery modules as the GS, but 28 of them instead of 40 in the GS. 

 

Thanks John, will be picking it up at 1 tomorrow, hopefully all goes well!

The batteries in the hybrid system do not require that they are used regularly they will hold there charge for months if not years. The 12 volt battery if the original will be at the end of it's life. It sits in the LH side of the boot. The dealers will have you believe it is special, but this is not the case. It does have a temperature sensor on it, but this can be removed and fitted on the top of any suitable size battery.

With all the electrics in the GS450H including the DVD player on the front screen a battery with as high an amp hour (AH) should be used. Minimum 75 AH ideally 90 AH.

If the battery is weak and the car left standing strange fault messages can appear on screen, and the car refuse to go to ready mode. The 12 volt battery is not used to turn over the engine. The car has no normal starter motor, and no normal alternator. These functions are done by the motor/generators in the transmission.

Thanks for the reply John

The dealer Battery check should highlight any issues including the 12v Battery yes? 

Have you had any hybrid issues with yours?

 

Hopefully getting one on wednesday too 

Just worried about the Battery life/issues, car has a full lexus service history including Battery checks and will have a Battery check when I purchase it 

I do very little driving and the car will have 60k miles 

What are peoples thoughts? Should I take the car for a long drive every week to help out the hybrid system or is it necessary?

How common are failures  of the hybrid system
