"Engine failure" More like coolant failure. I think you are overreacting a bit. While I'm beating down, one more..
DO NOT remove the coolant cap when the engine is hot!!!!!! It is under pressure and over boiling point, you can scaled your self and get steam burns. Both very bad.
Really, the issues you have are in many post here. It has almost nothing to do with how you are driving your car. Either the water pump failed, or one of the changeover valves failed. Both sadly are kind of normal.
You should also be under warranty, so it should just be annoying that this happened.

Only reason I opened the coolant cap because I was (improperly) advised by my client who’s father ran the largest supplier of heating components for high end exotics. He suggested I look at the coolant levels. I was very careful with it, and once I cracked the cap and saw steam coming out I let it air out. But still, stupid.
I just got a call from the dealer. Their conclusion was that my coolant cap went bad... I find this hard to believe but will monitor it. If it happens again, it’s likely one of the options you mentioned above.
Also, mine is a 2017, so I’m out of warranty as of July last year. Which is why I was having a bit of additional concern when the dealer calls me and says they are running a compression test on the engine.

Love this response. Agreed, overreaction.

We all can get a little crazy when the car does something stupid. Yes, it CAN be the cap, but I would keep an eye on it, and carry some spare water for a while just in case.

Just took mine to the dealer at the same mileage 2017 4S. Have been watching a leak since ~3K miles, but it has been very very slow; pink residue, and an occasional hanging drop. Never anything conclusive on the ground.
Have since bought a few water pump and bench testing the seals and vacuum capabilities, as well as dyno testing the functionality of the engine's vacuum control of the pump. Will be posting some data soon.

I have a late build 2019 (it was my dealer's last 991.2 allocation AFAIK). I want to do a mild tune on it but this issue has held me back with 2 years left on warranty (and I don't believe APR pro-rates their warranty tune). I ask them to check this every time it's in. I had it in a few months ago for a frunk latch recall and they put it up on the lift for me to show all was well (they have been great to deal with). The tech shined his flashlight up to the side of the water pump and said "you even have the upgraded xxxxxx" (I missed what he said). So, I'm hoping this one holds up.
Good luck getting your repair and please post final verdict...

I am almost two years into ownership on my '17 C2, bought as CPO from the first owner at a dealership. So my OEM warranty runs out in August, but I have two years till '23 on the car but still. There are a couple unexplained service visits on the Carfax that may or may not be a WP recall service. For sure "at the moment" there's no pink on the floor, and I check the water level religiously cold once a month.
OP - good luck with your car. Hope it is fixed soon.

To catch a leak before full failure you need to look on that left side pipe area as opposed to on the ground. It's likely to drip on those adjacent parts before being enough to reach the ground. I would assume almost all 17, 18's, and probably many 19's will experience the failure. It shouldn't involve engine issues unless someone runs the car hot. I'd be dubious that a bad cap could explain it when it's such a documented failure.

If you look at the water pump failure thread, there doesn't seem to be any revision that solves the issue. Speaking with a local Porsche specialty guy, he tells me this issue has been around for many generations. I have a brand new latest revision pump we've been bench testing, and it does not hold very much vacuum before the seals leak

I swapped out the water pumps on my E46 every 60k; they were just consumables like the thermostat and accursed expansion tank.

damn...,more reason to get extended warranty on this car then... was on the fence since my 981 of 6 years was pretty much trouble-free and had nothing but cheap fixes...

I bet it only fails at 1-2 times for the life of the car. Part should be better as time has gone on. Maybe some of the 19's won't have the issue at all? Curious if any 2019's have had a pump go down?

I don’t have any hard evidence, but taking a cursory look at the 992 forum it’s pretty clear that this still has not been resolved.
I wish I could get away with running my business this way.
