Formentor hybrid dead after software update
Curious if anyone here has had a similar experience. I got my charging flap replaced at the dealer last week under warranty. They told me while it was in, that there was a software update due on the car. So I had it done. No problem.
Came out to the car the next day and it was totally dead. No unlock, no hazard lights, no start. Nothing.
Cupra called out the AA who found the 12V had drained down to 3V.
They’ve taken the car back to the dealer now to fault find. I discovered my dashcam (which has been in the car for six months, and always shuts off with the car) stayed recording until 3am the day it came back from the dealer.
Is this a known fault? The 12V system usually always turns off with the car, but for whatever reason it now seems to stay live and kill the battery. It’s never done this before until this most recent update.
