Recently posted about a 2022 Genesis G70, where the radiator nipple was broken off near the cap. Well, I've not yet repaired it because it is almost certain the Genesis of Round Rock shop broke it. Background:

-Car was purchased from Avis last October, still within manufacturer's warranty today
-Quickly took it to Genesis of Round Rock for multi-point inspection where no issues were found
-Until a few weeks ago, no repairs and only service was two oil changes, and not at the Genesis shop
-A few weeks ago, noticed some oil under the car, took it back to Genesis of Round Rock
-Genesis identified a timing cover leak and repaired under warranty
-Genesis calls after the timing cover repair, saying they "noticed" the broken nipple
-Genesis claims they did not break it and suggests it was like that from Avis or an oil change shop
-No chance it's been driven that way for long without overheating
-YouTube videos show the fan cowling must be removed to repair the timing cover leak
-AAAND...the fan cowling attaches to the coolant reservoir hose two inches from the broken nipple!

So there's no way to prove they broke it, but the background info shows they almost certainly did. I've spoken to the service manager and he's pushing back. Strategy advice? Is Genesis Customer Care going to just back the shop? Small claims court? Other ideas? I'm furious with Genesis, but don't want to waste time on a lost cause.

The sequence of disassembly to perform the repair is what you should be citing to the service manager if you haven't already and also reiterating that there was no coolant leak or overheating prior to their work of the timing cover.

Agree with the above that you should escalate this to Genesis directly if the dealership does not correct this. Genesis is certainly able to pressure the dealerships into making things right, I know this from our dealings with our local Genesis dealer.
