Same for me too. What kind of alternate universe are we in where an almost new Toyota can't be counted on to start and the dealer just shrugs and says that is normal?
Again, easy for me to say since I still have my 3rd Gen, but if it were experiencing this, I’d start looking into a lemon law claim. See what you need to document and so forth, state specifics can vary.

Just because somebody at the dealer says something, that doesn’t necessarily mean it is Toyota‘s official position. Make some noise. Get their attention. TV news consumer advocate if you have one. Open a lemon law claim to make it official and elicit Toyotas official response.

All properly functioning cars and trucks should keep the 12v battery fully charged. Failure to do so drastically shortens the life of the battery, as well as creates a safety risk when you can’t trust the vehicle to start anytime you need it.

I have owned so many Toyotas that I am not very familiar with lemon laws, which I guess needs to change. I know some lemon laws state that the dealer has to correct the problem in three attempts or 30 days out of service. But what happens when the dealer says the truck is actually fine? They can't fail to repair a vehicle which they say is working properly, right? Maybe this falls more under a class action lawsuit? I know there are a fair number of hybrid owners in this same situation and Toyota does not seem to be doing anything about it.

Completely agree on the battery. This may be how Toyota designed it to work, but that doesn't change how batteries work and the 12 volts in hybrids can't last very long. I guess they determined that they would last through the warranty and after that it is the customer's problem. I will hope to get around that with an Optima yellow top and I already bought a jump pack to make sure I can get it running. That seems pretty lame for a halo truck but maybe that is all we can expect from Toyota these days. If I were you I would hang onto that 3rd gen.

Has anyone in this discussion had their truck actually not start? Until that happens I don’t see the issue. I’ve left my truck for weeks (maybe a month?) and it fires right up.

Yes. I have and others have as well.

Well I have a 24 TRD Sport Premium and had battery issues.

First time died I was using the bed inverter with truck in ACC for literally 5 minutes to print a document off a printer I had plugged in, truck wouldn't start.

Then I left the truck in my garage for 3 days while on a trip. Truck wouldn't start. I took it into the dealer and they "tested" the battery and said everything was fine "it probably just needs to be charged". I then took it home. Left it on my charger for a while. It was working ok until the first cold snap hit us. Dead again after just sitting over night. Then died every time I turned it off.

I ended up replacing it myself. This is what I put in it based on one of my customers (Midas) that took care of me.

Battery issues seem to be fairly prevalent with many having good luck getting them replaced under warranty. I got tired of the BS and do not have time to leave my truck for an entire day for them to "we can put our lead mechanic on it and have him do some deeper testing" (WTF Toyota)

Your battery may be different for the Pro Hybrid.

That is one of the things that is confusing. Why are some trucks fine after sitting for a while when others go dead overnight? I think it is clear that deep discharge batteries are needed in the hybrids, but they come with normal lead acid batteries. Then when they fail Toyota sometimes avoids the warranty claims by denying that there is anything wrong. I charged my 12 volt to 12.85 volts with a charger but after a week of driving it daily the battery settled at its usual 12.2 volts.

It seems that most hybrids keep their 12 volts at a very low state of charge, and that definitely means a short life for the 12 volt battery. The ICE is started from the traction (hybrid) battery, so if the truck turns on it is going to start. What is really bad IMO is not that there is a problem, but that Toyota insists that new trucks which fail to start are functioning correctly.

From what I understand - again I'm armchair quarterbacking and YMMV - if the dealer claims something is normal, and you've documented repeated attempts to get the dealer to fix the issue, one would get a diagnosis from an independent mechanic documenting the issue as abnormal and the dealers refusing your attempts at resolution. This then would be the basis for the LL claim. Chance of success would vary due to different state laws.

In this instance, don't get distracted with the "doesn't start" stuff. Focus on the charging system failing to fully charge the 12V battery. When the dealer says "oh the battery just needs to be charged" or they say "you need to keep a jump pack ready" or "put it on a trickle charged" that's all supportive evidence. Couple that with an independent mechanic confirming that achieving only 50-60% state of charge is not "normal".

While a deep cycle battery may help, it still doesn't solve the core charging issue IMHO. I'd keep being a PITA to the dealer. Build up the count of days without the truck / number of service visits. Again real easy for me to say since I have a couple nearby dealers and a funcar to drive if I had to leave the truck at the dealer - most don't have that luxury.

And yes, I'm thinking to stick with my '17 a while longer. I was all eager to go to a 4th gen hybrid earlier, but this issue and some other things are very concerning.

I'm going to push back on the idea that deep cycle batteries are needed on the hybrids, and instead suggest that some portion of the hybrids are failing to keep the 12V battery fully charged. A deep cycle battery would merely mask the underlying faulty charging system.

I would also push back on the assumption that what the dealer says is Toyota's corporate stance. I think in another thread we had the diagnostic info from TIS that suggests the 12V battery should be getting fully charged. Challenge the dealer to show documentation that 50-60% charge is actually normal and they're not just saying that to make you go away.

The part I find interesting is we have a few people here with the issue, but I'm not seeing much mention on another forum. This further suggest that some portion of hybrids have a faulty 12V charging system, and only a subset of those are then noticing the impact of that.

I agree but a deep cycle battery will probably keep my truck running and I am not ready to move on yet. I don't want to sell my truck until I get past the first couple of year's big depreciation hits. This combined with my truck being in the transmission failure VIN range probably means that I will not keep it in the long run anyway.

Yes, the charging system is obviously not working as it should, but since virtually all dealers tell their customers that the trucks are fine, I think that is Toyota's corporate answer. What the service writer told me was identical to what other dealers have told other customers. They didn't have my truck long enough to diagnose the charging system or the battery, they just trotted out the corporate lie.

I talked to Toyota Brand Engagement and they said that they can only help when the dealer says that your vehicle has a problem and they can't fix it. If your dealer says it is working as intended it is up to you and possibly your lawyers. I will take the same approach as @goin2drt, and come up with my own solution.
