How are the above two engines reliability , performance , etc. in late the model Toyota Highlanders ? Any engine concerns or noted issues to be aware of ?
 
Well, this all depends on the specific model year. Are you considering NEW or Pre-Owned?
The Toyota Highlander is among the most reliable vehicles you can buy and Toyota hybrid engines take that reliability up a notch. However, no vehicle is without an issue here & there. Not a problem per/say but an occasional mishap.

Some Toyota 2.4L 4 cylinders had oil burning/blow-by due to the low friction(and sticking) piston rings as do most car manufacture's who are using low friction piston rings. Some engines use oil and some pollute their oil with fuel.

Most Toyota's are a safe bet but good maintenance & condition is everything.

The 2.4 in question is the new turbo 2.4T that Toyota is using.

I haven't heard too much negativity about it, but the engine is fairly new. It is a pretty stout built engine though, but time will tell. The 2.4T in my Tacoma is a solid engine, although is configured a little bit different than the transverse version. There are a couple cases in the Tacoma where the oil filter and or housing wasn't situated correctly and dumped all its oil resulting in a destroyed engine, but that is rare.

The 2.5L hybrid is also a solid choice. That combo is in a whole bunch of Toyota's right now.

We will not know about the long-term reliability until someone puts 150+k mi on a 2023 which is probably at the earliest the end of 2026.

At an avg speed of 30 mph, that is 1700 hrrs/yr or 32hrs/week of driving. A daily round trip commute of 4hrs is only 20hrs/week. Lol

There's bound to be some medical carriers or the such that will rack the miles up very quick.

Can't really compare the Highlanders 2.4T to the Tacoma/4Runner's 2.4T as there is too many differences to make an even comparison. I'm betting with proper maintenance both will be fine.

Isn't that 2.4T engine used in some Lexus models prior to the Tacoma from like 2021?

Yeah im not sure if it’s the exact same one but a 4T has been the in the Lexus GS for years. The pairing in that vehicle has never received good reviews but I’ve not read a single complaint on the engines themselves. I’ll say this, I’d gladly have a GS 200T while everyone else writes undesirable reviews on it.
 
I was initially looking at a new Highlanders in February 2023 when I ordered my Rav4 Hybrid. They were more than I wanted to spend with some bells and whistles added plus the 3.5L gas engine. The used 3-4 year old ones on the lot coming off lease were only acouple grand cheaper then the 2023s. It was a NO BRAINER!! I wanted something economical/reliable/safe but in my price range soo just went with the loaded Rav4 Hybrid and "very" happy I did. I am content what the 2.5L Hybrid does in my Rav4. Its no performance engine -- built for economical reasons along with safety in mind from Toyota. I accept that, personally -- I would not like this engine in a Highlander do to the added weight. Its ALL about contentment and nearing 20K on my engine -- routine maintenance and so far so good.
 
Like a few posts above, too early to know for sure. I have reservations of long term for my usage (200-250K) miles. I'm also skeptical of that engine pulling a large and heavy vehicle. THis is on my list for new purchase in 2026,

Not considering a turbo engine if I can help it as I don’t need it . The Highlander Hybrid appears to be a solid choice though from thread comments .

Good points - I would think the 2.5L hybrid would need a “boost” up from the RAV4 to account for the Highlanders added weight ?

I wouldn't be too concerned about the turbo motor. I can watch the boost gauge on my truck (they're probably very similar in weight) and under normal circumstances it hardly ever needs to go under boost. I doubt it's stressed. But, I can respect personal preferences. I like turbo motors myself, so I guess there's some bias.
