I had the same issue with my 08 Infiniti G35x. Had to end up pulling the fuse to the over head lights and electric seats. Issue solved. No problems since. Hope this helps someone.



G35 X for about 3 years now and it's a certified preowned car. I absolutley love it but lately have been having some issues with the car. The car has about 45,000 miles on it and the battery has compltely died on the car a few times after not being driven for a few hours. I.e. went to a driving range, hit a bucket of ***** for a few hours, came back to the car to have the battery be dead. I would get a jump and the problem wouldn't occur again for another 12 months or so.

But recently it's been a bigger issue. About a month ago, I found my battery compeltely dead after sitting there for a full day and tried a jump but didn't work. Checked the volts and it was down to about 2.50 V so ended up replacing with a brand new one. I switched my tires over from winter to summer ones yesterday and the car was driving fine at about 7 PM. Then went to turn on the car this morning around 6 AM and battery is completly dead and voltmeter is showing roughly 7.60 V.

Any one else having a similar problem at all? Could it be the TPMS? (since the winters didn't have the sensors, then again I dunno how to explain the times this has happened with the TPMS sensors on my summer tires). Also, I should mention that the radio has been acting wierd latetly. The frequency seems to switch automatically and sometimes goes back to the station I was listening but not always. Couldn't this be an indication of a electrical problem with my radio and the possible cause for a battery drain?[/QUOTE]
