  1. Our drain wasn't caused by the lumbar support. The diagnostic report showed there was a parasitic drain from the onboard body control module which was discharging the vehicle when it's switched off. Alternatively, it could have been the body control module also powers the audio module which is another item that can sometimes have this parasitic drain problem.
  2. I didn't know that lumbar support would cause a drain. Isn't it 'just padding'? --- We had the car about 4 years and it wasn't an issue before. The drain was so 'strong' that a new battery was reduced to 43% of its life within 2 months. Not using the car for a day or more resulted in the battery being so flat that we couldn't even lock the car with the button on the key, but had to do so manually. We have now sold the car. We got less for it because we declared the fault but that's only fair. 🙂
  3. We've got the same problem with our 2008 IS250. The battery and alternator are fine, so we had an electric specialist come and have a look. We learned that there's a parasitic drain from the onboard body control module which is discharging the vehicle when it's switched off. The body control module also powers the audio module which is another item that can sometimes have this parasitic drain problem. Either way it needs repairing or replacing and 'regular' garages don't seem to have the software or coding skills needed to fix it. So it will have to go to Lexus & that's going to cost a lot! 😞 Has anyone managed to remedy the problem? If so, how and how much did it cost?
