And given the fact that hybrid engines last just as long as other engines lets me know that even that worry is unfounded.
Exactly this. I can’t be bothered to worry about other’s unfounded fears, that are based on theoretical damage scenarios, that have never been proven.

It’s simply sowing FUD, fear, uncertainty and doubt.

It's the 3rd gens with the issues not the 2nd gen. 2nd gen was basically bulletproof.

No idea what causing the HG failures, many theories but one of the most prominent is the fact that the water pump is electric and on the 2010-2012's they don't throw a code if the impeller detaches and the RPM of the pump increases beyond normal spec. According to a guy who owns a shop, 90% of the HG failures are accompanied by a failed water pump.

I replaced my wife's 2010 water pump pre-emptively at around 140k.

The other theory is heat cycles, because hybrids don't heat up once per drive, they heat up and cool down. Toyota may have tried to cut too many corners with the 3rd gen, who knows.

Another is coolant. People don't swap their coolant out enough and it turns acidic and starts eating the headgasket itself slowly over time.

Good news is Ford doesn't seem to have that issue on their uber-reliable 2.5l duratecs that power their hybrids including the Maverick.
I had a 3rd gen Prius. Engine pumped coolant into the oil and it seized at 185k miles. The car was worth $5k, and a rebuilt engine would be $2k, and Peddle.com offered me $3500 for scrap, so I sent it to the scrap yard and bought a new one without tearing down the old engine to see what failed. I didn’t know that head gaskets were an issue on 3rd gen Priuses, but now I’m pretty sure mine was a head gasket failure as well.

Quick google search says that the EGR cooler valve is to blame for the head gasket failures in Gen 3’s and that head gasket failures in Gen 2’s were caused by the water pump failures.

I would be more worried about the hybrid engine starting when you on the freeway and it starts from 0 rpms to 2400 rpms in a couple seconds with no oil pressure yet.
I don't think the hybrid engine has a pressurized oil tank to supply oil to the engine before it starts up.
At least when you first start the engine when its cold, it starts up and runs below 1000 rpms.
Hybrid starts and runs under 1000 RPM? - not at all never, except for the entire time it's going from 0 to 1250 or higher RPM, and it's under 1000 RPM in the less than 3 seconds I posted above.

Other cars?
Been a long time since I've seen a car just first started not seem to jump the RPM to higher than idle then slowly come back down - even when cold.

Thanks to this posting I've been eyeballing that heat gauge more than normal. Last night, after a 10-mile trip the needle had JUST reached normal operating temperature--and it was 70 ' F day and in "Econ" mode. I'll try it again toddy in "Normal" mode and see if that speeds up the heating process. Jeff
That has nothing to do with when the ICE runs - has to do with changing the responsiveness of the Go pedal and brake pedal and coasting regen rate.

So the most it would have to do with ICE heating up different - is you pressing on the Go pedal different - and causing the ICE to kick on more.

" Regenerate rate/effect is different (L is actually the highest) - but the amount regenerated is the same whether the mode caused it with coasting, or your braking caused it - as long as you stay outta brake dust, it's all a matter of which makes it easier for your foot and terrain and traffic. "

Oh contraire!! A "coast down" from 40 mph to (say 30) in ECO results in a shorter distance than "Normal" mode. And in "Slippery" it takes far longer. Try it.

Jeff
L - ever looked in the center of your shifter dial?

Exactly!
Like needing to do some ‘Walnut Blasting’ to the valves at 70-80,000 miles like one member mentioned. All horseshit from being a worry wart.

The sky must be falling for some people. If it’s not then they will find a way to worry.

For all the pearl clutching over the auto start/stop feature of modern vehicles of all and the worry that it's going to cause excessive wear, I remind folks that hybrids start and stop MANY times more without incident. People seem not to realize that modern engines are DESIGNED for this. And they run without incident for a looooong time. The only engines that have excess wear issues are those that are notorious for being designed poorly. And even then. It's not because of frequent starts.

video brought to you by mobil1?

I mean, I usually use mobil1 on my oil changes but I've never bought a hybrid specific one on purpose. I just look for the best deal on full synthetic.
Exactly! If hybrids required oil specifically made for hybrids, the manufacturer would say so.

Pretend you never saw this posting.Just drive. Don't try to make the needle do anything. Don't stress or change driving habits over a non problem.

He needs to forget that he ever saw this series of posts and just drive as he's always driven . All he's doing now is worrying over a non existent problem and "solve" it by now driving in a way than burns more fuel 😅. I wish my driving habits allowed me to get minimum gas engine operation and maximum efficiency. I wouldn't care how long it took for the temp to rise as long as everything works and there's no check engine light. People need to relax and let the car do what it does

My observation: most of the people who have the most complaints horror stories about the reliability of a Ford or Toyota hybrid are people who have never owned a Ford or Toyota hybrid. And most who have complaints about the reliability of a Ford hybrid versus a Toyota have only owned the Toyota hybrid and never owned the Ford hybrid. With the Ford Maverick hybrid the only consistent complaint isn't really about the hybrid system. It's just the battery drain that some experience

"require" and "benefit from" are not the same thing.

It's plausible that oil manufacturers figured out something that benefits the hybrid use cycle. Whether they succeeded or not is a matter of data, not of generalization (and I personally have no idea what the answer is!).

My opinion: the benefit is probably theoretical just like the problem is theoretical since there's no present problem happening. The real benefit is to their profits. Again it's my opinion. And my opinion is probably worth as much as you paid for it😅

Which major companies make hybrid specific motor oil?
Mobil One, Valvoline, Castrol, Amsoil.

Which ones don’t?
Motorcraft, Phillips 66 (makers of Motorcraft)

If I see some hybrid specific oil, I'll buy it if the price is equal to or less than the factory recommended oil . Otherwise, it'll stay on the shelf. 😅
