Nobody has been able to figure this out.

2010 Altima 2.5 4cylinder w/CVT. Catastrophic engine failure due to overheating. No warning. Clueless as to the cause.

I'm a high school teacher with a 2010 Nissan Altima 4 cylinder w/ CVT that currently has 150k miles.  Nobody has been able to give me an answer to something that happened to me 1.5 years ago.

The "Service Engine Soon" dashboard light was on two years prior to the incident, I took it to my local mom-and-pop family run shop we've been using for many years, they find an EVAP code.  They do a smoke test for 2 hours.  No detectable leaks.  Change gas cap just to be safe.  They said to just live with the check engine light being on.  One year later I'm driving down the highway, the engine starts grinding and I have a catastrophic engine failure at 125k miles.  Tow it to the same shop. They say the engine overheated and I need a new engine.  They install a used engine for $3800.  Everyone thinks I let the engine overheat, but there was no change in the temp gauge, it did not go to hot, no other lights came on, no indication there was an overheating problem.  Nobody can explain what happened.  It has bothered me everyday since because I am not so oblivious that I wouldn't notice my engine overheating.  Any ideas what happened to it?

By the way, the "service engine soon" light is still on to this day, with the second engine in it.

I already did. I have a 2018 4Runner TRD Pro. I use the Altima as a daily driver and I baby my 4Runner, I love it so much. I need to get it undercoated though, I know they're notorious for rust. Thanks for the reply sir.

nissan makes junk these days, period. Never buy another, I don't know if it overheated and broke or more commonly they just break internally, then they overheat. Chicken or egg thing. Get a toyota next time
