Hi all,
Hope someone can help with this?

Only had the car since July last year with 44k on it.

I have a Carley OBD scanner and run a scan about 3 weeks ago, one thing came up was battery health, said battery health is very poor 65%, so I got new one,
So then last week when it got cold, went to start the car, nothing, used a jump pack, fine, then it has been on and off since, sometimes come out of work and will start other days it won't?
Then today, went to my car at lunch, pushed the remote to unlock her and the rear came up but did not unlock car, tried a couple more times then it opened?
Then tonight, came out of work, went to car unlocked it, but no lights, mirrors still folded in but door unlocked, got inside, no lights inside, put key in turned it, nothing, turned it again and starts up no problem???, also I get out of the car and the spoiler is up by maybe 1cm, but I am unable to get it to up or down by the button inside, then whilst on the home the light came on the button and I could move it and down.

I change all the small bulbs in the car to led's, like the footwell, boot and number plate, maybe they have Messe up the electrics?

Only ever had Fords before the RCZ, love the looks and the drive, but not a good start to ownership, just worried now that ill go out in her and can't get home.

Any help would be appreciated

Battery control module will cause these issues & they do fail on the Zs

Wow that's amazing if it fixed all your issues. I wonder how many people go down a rabbit hole chasing solutions for electrical problems and it's only the circuit board on the module! Such an easy cheap fix!! Keep us posted if it keeps working to fix your issue @ZerokoolRCZ
BTW mines still fine since I did the same fix. (y)
