2023 Lexus NX 350H

[warrken52]

Bought my first Lexus for retirement after all the positive reviews and test drive.The problem I have encountered is a flat Battery after I haven’t used the car for a few days and the last time was only a couple of days ago while I had the doors open when fitting door sill protectors.Lexus advice was, I need to use the car more often which wasn’t much help .The car had only covered 1k miles and wasn’t expecting issues so early on in my ownership.My conclusion is either the 12v Battery capacity isn’t high enough or there is a Battery drain problem . The only drain from what I can conclude is the interior lights .Your comments would be appreciated.Thanks.

There must be literally thousands of posts here about the small 12v Battery running flat.

A quick read through the site will explain. Many members (myself included) have made the same mistake.

Long story short - the 12v Battery is tiny. Turn the car on if you’re going to be working in it for anything more than a minute or two.

Get Yourself a Noco Battery pack I Have the GB40 For that very occasion keep it in the Glove compartment Rather than the Boot..great advice Here... BTW...Love your Car...Amazing !! Well Excluding the 12v Battery..!!!

Yes I bought a Noco GB40 and as you mentioned and it’s  a god send.I have never had to jump start a car for years when I ran old cars and never did I think I would have to jump start a car which cost nearly 60 grand.I’m at the moment a very unhappy Lexus owner.
