Head gasket OEM Honda or OEM Toyota

Just from a bit of personal experience and a few friends stories, the 2ZR-FE. For a motor used in so many of their cars (2009-2012 Corolla and 2010-2015 Prius) you wouldn't think they'd be blowing head gaskets at all. I have the same motor in my Scion xD and blew the HG at 150k miles.

I'll toss in the 7M-GE/GTE. Pretty much guaranteed to have a failed head gasket due to under-torqued head bolts unless you caught it ahead of time. Usually happened at the back due to excessive heat at the rear of the engine.

I drove my 2003 Honda CRV with a blown head gasket for over 6 months. Drove it everywhere knowing it was on its last leg. The engine would go into “safe” mode often to protect the engine. That means i can’t accelerate past 60mph. Had to change the spark plugs once a month. Had to add oil and coolant every single time i drove it. Oil showed up in the radiator AND over filling the over flow. Finally gave out three weeks ago.

I just made a key to a 22 toyota corolla cross with 9200 miles on it and the head gasket was blown, was at an auto auction, the wreck wasnt that bad at all I was really surprised, I've made keys to 10x worse and didnt burn coolant lol

I have a 2010 with 218k miles loses zero oil but I lose coolant think I have a head issue. But I've put about 20k on the car just topping off coolant once a week. I would say the head gasket issue is pretty high I've never had a car with a bad head until now.

Mine went at 220k, 2015 Prius V. Fixed it myself but I had the tools/time/interest. If you’ve overheated already it’s probably warped the head, cheaper to get a new (used) engine, have them put a new head gasket on that engine before it goes it to ward off future trouble.
