Hi there,
Really sorry I’ve not responded before now. I have only just seen a email from the group chat this morning. Basically we rejected the first Q3 due to this issue. The replacement has been fine apart from only one occasion on just over a year where the message came up. I really do think this was because of the car being fairly new and I presume the battery wasn’t charged enough as others have said. The old Q3 kept coming up with the message quite frequently. I do hope you get yours sorted. Please feel free to ask any more questions.
