it  FL2 MY10 TD4 GS traded in at 2 years

And there's why I love this forum  FL2 TD4 GS 60 reg Facelift - so many issues
2019 DS. Terribly unreliable.
Sold DS for a 2021 Mitsubishi Outlander PHEV. Fingers crossed....
Sold Outlander for a 2014 SD4 SE Tech because I’m mental
Now greatly regret selling the Outlander. MPG of the FL2 is atrocious and so are the fuel bills. Fun though 😎
Couldn’t afford the fuel bills so back to an older Mitsubishi Outlander PHEV. Significantly better than I remembered it to be…

Hi, for the rear 12V power outlet if its no working first check the fuse which is located in boot ( 15 FA6 ) if its still not working change the power outlet its very cheap available on ebay, amazon 3-5 pound and very easy to install plug n play. and if you are using only for charging mobile choose the usb socket instead of power outlet and usb plug .

Great info on this thread. Boot not working, and only one of the two front ones.

Failing that i have 3 months warranty.

I have the same problem. Both fuses seem to be OK, yet there is no power to either the cigarette lighter socket in the boot or the rear of the 2 between the seats

Check for corrosion on the relevant fuse, or replace it if not done already, as sometimes a fuse looks ok but isn't. Hyundai Ioniq 5 Ultimate. The family car.

When my boot socket stopped working I somehow confused myself and missed changing the correct fuse.

However I discovered this thread which helped me understand how the fusebox worked (and how fragile it could be)

Mine was only a fuse, so my advice would be double check that you have the right fuse, FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)
FL2 Metropolis SD4 Auto 2014 2017- (16k - 77k+ miles) (MY2015)

Checked the fuses in the boot and when I removed and replaced FA6, the socket started working again!!!

The bad news is that I tried that with FB10 for the boot socket and still no power getting to the socket. 12V at the fuse, so maybe a faulty socket?
