Is there a known problem with the Peugeot 5008 electronic handbrake?

I have a 2016 Peugeot 5008 automatic that was stored for three months over the winter. I took it for its first drive of the year yesterday, but as I was pulling away the parking brake fault light appeared on the dash. From what I can find online it appears to be something to do with the rear brake pads and disks. It doesn't appear to affect how it drives or stops, I was wondering if this is a problem with these handbrakes and if it would be fixed under warranty. I don't live near the dealer where the car was bought and I never had any dealings with my nearest Peugeot dealer, so I'm not sure how to go about getting this fixed.
The electromechanical parking brake will have clamped the rear pads onto the discs and since both have metallic content there will have been some rusting between them. It could be that a bit of heavy braking cleans this off. If you leave a car standing for extended periods it's best to leave it in gear with the parking brake off so this does not occur. If the light stays on, book it into a Peugeot dealer to get checked. If the brake discs self-clean through driving then all that might be needed is to clear the fault codes from the ECU.
