If it's a metal fitting into a plastic housing IT WILL CRACK AND BREAK IT.
First rule of plumbing and piping, plastic screws into metal, metal does NOT screw into plastic. You have two materials of differing strengths, and the plastic WILL yield to that metal fitting, boom, coolant jacket cracked, battery on fire, people will die and it'll be totally metal.
Another example: When you change the transfer case fluid on a 2007+ Ford Expedition or F150, if you aren't careful when you put the drain and fill plugs back in, to the proper torque and no more, the steel tapered thread drain plug WILL split the aluminum transfer case wide open and now you're out thousands.
That's metal to metal. Even high pressure plastics like Schedule 80 threaded fittings will crack like an egg if you screw a brass fitting into it even a in/lb too much.

I'm glad fivepointeightnate stated the obvious before I had to.

That's actually true in many cases, and it's for a good reason: who wants to do your own work when you're paying already for someone else to?
And by that I mean most leases on high-end cars include ALL maintenance for the life of the lease. You're already paying for the dealer to replace your wiper blades, change your oil, even vacuum and wash it in some cases. I know a local dealer that even picks your car up at your house for service and leaves a loaner. That's in the lease price. You get a worry-free automobile for 3 years, then you upgrade to the newest one. It works out for the dealer because then your 3 year old 36k mile used lease, which they hold the records of all on-time maintenance on, gets sold at a premium as a 'Certified' pre-owed car by the dealer.
With cars like BMW for example, this makes the most sense, because with their maintenance schedule you'd be on the hook for thousands + in just routine maintenance yearly on top of the high monthly payments. Congratulations on having your car for a year, it's due for it's "Service II", that'll be $7500.
It's why used BMWs from individuals can usually be purchased inexpensively (relatively) because they deferred all that scheduled maintenance that makes it drive so well. Been there.

Wait, PAUSE...HOW did the nozzle get broken in the first place? If it was someone that didn't know what they're doing, well, that's on them, I have little sympathy.
If it was a garage that screwed up and broke it, they're liable to PROPERLY fix it, that's why they're bonded, insured, licensed, etc and I have little sympathy.
If the nozzle just broke on it's own, on a otherwise working vehicle under warranty, I'd expect the dealer/car company to warranty it, and I have little sympathy.
Without knowing how the part broke, or who is to blame for breaking (and if negligence was involved), I'm leery of immediately blaming the manufacturer.
If you put antifreeze in your crankcase because you don't know what you're doing, that's not the makers or dealers fault, is all I'm saying.
I support right to repair, but only when the repair is competent.
