My wife and I rented a 2025 Expedition Platinum Max with 15000 miles on April 2,2026. Engine started knocking about 1/2 mile from car rental lot and received a “low oil pressure” warning message. Immediately shut off engine. Checked oil level ok. Tried restarting a few minutes later. It restarted and went into gear but generated the low oil message soon after. Not impressed. My 2001 has the original engine and trans and runs smooth and quiet.

Sadly I have to more look at the fact that it's a rental and who knows if in 15k miles its even had an oil change. we very rarely hear of completely dead 4th and 5th gen motors. that much i can be positive about.

Then I'm sure you know these forums are often filled with 2/3rds complaints (just like my history on here) and if there were lots of these motors just flat out dying at 15k miles, we'd hear about it. But hey, Toyota is still replacing motors for essentially that outcome, guess maybe it's too early in the 5th gens to find out.

failed oil pump?
I understand that you are an experienced auto mechanic, but I probably wouldn't base the reliability of a car on a rental.
Furthermore, the 3.5 Eco has been out for over 15 years, and has never been associated with low-mileage failures to my knowledge.
The 3.5 has indeed had some issues during its evolution, but third generation is pretty darn bullet proof.
That being said, things happen - we had a Mercedes Sprinter van purchased new and meticulously cared for diesel that whole engine failure at 25k miles. Luckily Mercedes did a full engine replacement, never heard cause but again - defects do occur in these amazing power plants we see in use…

I totally agree!
Years ago, my new Pontiac Grand Prix developed an engine peep at 50 miles. My Cadillac Fleetwood Diesel needed a new motor after 5000 miles, my Ford F-150 pickup developed a bad tranny after 2000 miles, My Lincoln Mark VIII lost all suspension after 500 miles. They were all purchased new. I can keep going
95% of my new and used, 1–3-year-old cars and trucks have been perfect or near perfect. My '25 Platinum has an adaptive cruise control issue and passenger retractable running board knock, that will need service.
My point is every vehicle manufacturer has some lemon vehicles or at least vehicle issues. That's one reason why many people choose to buy a used low mileage model. Most of the time all the headache malfunctions are repairs. And if 1 year old with 12,000 miles, it gets a longer warranty, (Still 3 years 36,000 mile and 7-year 100,000-miles powertrain warranty with 6 years left), compared to 5-year 60,000-miles powertrain.
