Hi all, First post here.
I have a 2006 rx400h purchased with 30k miles 18 months ago. We drive the car a few times a week and regularly on weekends.
The 12V SLI battery was dead 6 months ago, I figured it was 5yrs old and time for a new one, so i replaced it, this worked for 6 months.
One month ago the battery was again dead. I Had the car jump started and drove it for a day, the next day it was dead again... bought a trickle charger, took battery out and charged it in our house overnight, it then worked for a day.. and then was dead again. I took the battery (6 months old) into Kwik fit, they gave a free replacement. 3 days later the new battery is dead as well, repeat cycle of jumpstart, drive, trickle charge, etc... dead each morning.
Took car under AA 5-star warranty to a local garage, they looked for 4 days, alternator fine, battery fine, they cant find a problem.
Have now booked to take it to a lexus for them to look (of course its dead so will need to jump it to get it there). and now its not covered under warranty.
A quick search shows a history of these electronics problems with some ghost draining the battery overnight... but why all of a sudden after 5 years of no problems and a new 12V battery? I cant believe that a 'luxury' can needs to be trickle charged with a solar charger each night... never seen a range rover or an X5 with this problem
any help or advice would be appreciated. I'm getting tired of spending my nights unhooking the battery to bring it in for charge, then the mornings putting it back in so my wife can take the kids to school (parked on public street).
HELP!!!!
