GR86 Flat battery after being parked for 2 days

Mine has been left for a week here and there and started ok each time. It does sit on the CTEK quite frequently though.
 
Hi, Exactly the same issue with mine, (same reading as above) and no doubt due to car being sat for several months pending excuses and delivery to dealership. Worst still is the ongoing poor service. I know issues happen but it how they are dealt with. 3 days chasing dealer and still no reply !

I’ve left mine two weeks before so I was very confused. Plus other cars I had/have are fine with being driven less than this.

Ongoing at the moment?

Doesn't fill me with much confidence. Hope they do the right thing and just replace them 🤞

I must charge my jump pack, thinking about it!

For other members concerned, suggest you toggle to the battery voltage display. If it jumps frequently between 12v and 14v you may have similar battery problems pending. Had to chase again today, and drop car back to dealer on Friday. Hopefully they put new battery in for me. Will keep you hosted.

From what I read that’s due to the smart alternator.

I got fobbed off saying their test showed the battery is good. I’ll probably get a jump pack to have about in case it does it again. But not too happy, they also washed my car after I asked them not too :(
 
Btw: Here in Germany we discovered, that our minus cables were not attached properly to the starter batteries on some cars.
 
I was away for the whole month. Had my 86 parked outside on driveway for 30 days. No CTEK change or anything.
Started first time. No issues. Battery readout 14V.
All you guys that have issues with starting after car not being driven for few days have bad battery or issued with cabling as Kosh stated above.
 
I collected my car Thursday and I know it has been at the dealers for 3 weeks so guess it has been standing most of the time. Drove it straight home so it has done 12 miles in total so far. Thought I would check the battery via a cheap lidl charger, it was saying 13.1 volts and there was one bar showing on the charging part (out of 4) so have left it charging since around 11am, just checked and it still charging showing 3 bars now. It started first time and didn't show any signs of struggling but I am just charging it as a precaution as it will be standing most of this week prior to spending next week having film applied.
 
Ongoing at the moment?
In fairness to Marshalls after speaking to the service manager they were pretty good. Dropped car in on Friday, and within 30 minutes was away, with new battery fitted. Hopefully others with cars from batch 1, (that were left idle for months) all get new batteries too if required. Good luck.
 
I came out to my car on Monday to drive it, and found it unlocked, and with absolutely no power. I ended up forking out on a Noco Boost Plus (GB40) via Amazon to bring it back to life.

For ref, I think mine arrived in the UK around October/November and sat around until my January pickup, and I've only managed ~400miles so that probably hasn't helped, but when it was started I did notice the boot was popped - I suspect that the button got pushed in my pocket (a common occurrence) and the open boot may have helped drain the battery?

Perhaps I should also invest in a leather key fob cover to avoid future accidents?!

It's possible that if the boot was popped, then the boot light was on perhaps? I think it comes on as soon as the latch is released. In which case, depending how long it was sat, that might have been enough to drain the battery.

The fob buttons do seem very sensitive for sure. It certainly worries me when I get to my car to find it car fully unlocked 😱
 
I left the car in garage for two weeks. Connected the battery yesterday to CTEK but it won’t recognise being connected and doesn’t start charging 😦

This can happen if the battery is very low, the charger won't 'see' it.
Some chargers have a 'force' mode to get around this issue, or you can put another good battery in parallel for while to get it charging.
Alternatively, use a non-intelligent charger to bring the voltage up.
If the battery stays very low for any length of time it will likely knacker it.

I tried another mains powered charger, but it had disclaimer that “jump starting” only works with voltage above 7.5V. And it didn’t work.

Can these cars be safely pushed out in neutral? As last resort I can jump start it off my other car.

Or just leave it until tomorrow and call Toyota? Would they even do anything or tell me to get AA? 🫠

Pushing is fine. Personally, I'd connect another battery up , leave it for a short while and it should take a little charge, then connect the charger. A cheap multimeter is a useful tool.

I wouldn't be trying to jump start it that way, only recover the battery back to a usable level - bear in mind this might take a fair amount of time
If it's any kind of 'smart' charger it probably won't deal with a very low battery.
Personally I'd take the battery out and try and get it back to something like normal - if it won't then it's knackered.
Can you measure the voltage of the battery? As Tim said, get hold of a multimeter.
Beyond that, probably the AA, if it covers 'at home' breakdowns.
 
I’ve got to admit I completely forgot about the AA membership included with the car.
I gave them a call on Monday and a lad with his charger showed up an hour later.
He told me the car’s battery is only drawing current at 1 Amp meaning that it’s probably knackered.
I didn’t switch off the engine and instead drove straight to Toyota. They wouldn’t take what the AA guy said and just said they would check the battery and leave it on charge on their “industrial charger”. Next day I was told it’s all a-okay and ready to pick up.

I hate arguing and I don’t drive the car much, so I’m just waiting for it to happen again really at which point they will have to order a new one

After a short drive home, here’s the battery gauge going between 13-14V. During the drive I saw it go up and down, but when parked it only went up while revving.
