No, wow, manufacturing defect? or would we not like you when you are angry?
Well, most of the break is clean, but part of the crack is dirty, so looks like it may have been developing over time. Just the sudden stress of thrusting my foot down was obviously too much for it! Although the shop looked impressed, they did say it wasn't the first one they've seen!

How old's the bike? Has it done a lot of miles?

Ouch! I do find I'm checking everything on it lately - but something unexpected will always evade detection until it fails! The bolt securing the rear brakes to the frame came loose a few weeks ago - the only warning I had was the brake lever juddering when I applied the brake.

People do a lot more than that on a Brompton. I've seen one on a 600km audax (600km in 40 hours) and I believe there are always several on Paris-Brest-Paris (1200km in 80-90 hours)

My front brake assembly fell to pieces not long after buying it. A proper strip down and rebuild at home & its been fine ever since. I do minimum 15 edge of the Pennines miles a day on mine in all but proper snowy weather & I even spotted Rose Bikes (IIRC) offering 16 inch snow tyres but I think the ground clearance would be a problem picking up the grinding paste gritter spray and snow sludge so readily.
On the few niggles people report: I do wonder if Brommy are working at full tilt to grow and meet the demand over the last few years and that final touch of QC has slipped a tad, but shops are taking them on bombproof reputation & trust. A quick bit of home TLC seems to be the thing to keep them as good as public preception.

My Brompton dealer tells me Brommies usually come out of the box ready to go and few require much adjustment.
But I think you could be right about Brompton taking their eye off the quality control ball.
These days they seem more concerned with style, boutique shops and marketing in general.
Ramping up production of any niche product often seems accompanied by a dip in quality, so if there is a problem, Brompton should have seen it coming.

That's what happened to my first M3L. I had removed the seatpost and noticed the break from the inside at exactly the same place.
