I didn't engineer the thing, so I don't know what parameters it needs to release the rev limiter, but it's right there in the manual. I don't know what else to say lol.

Dude, it’s not a cold start issue.
ive been able to replicate this issue in a variety of different conditions, recently after I drove the car hard for an hour, when the temp was 60 degrees outside, 70 degrees, and when it was cold outside. It’s literally random and HAS NOTHING TO DO WITH COLD START PROTECTION. Even when the car goes into gear, literally no power for 3-5 seconds before it kicks in. That’s not cold start protection, that’s a defect.
and no, I’m not revving the car within 30 seconds after startup as per BMW picture you posted. this happens randomly even after the car is warm and started up for several minutes.
We’ve got about a dozen people here complaining about the exact same issue on their brand new cars, how in the hell do we start getting Toyota’s attention to address this issue?
im Not taking this to the dealer again. Even if they replicate the issue they are going to tear my brand new car apart trying to figure out the issue, which they will never figure out. No thanks!

One more thing to add — for those experiencing this issue, if you have not already done so, call Toyota corporate and OPEN A COMPLAINT TICKET. Save the number for future reference. That’s probably the only way we can get Toyota’s attention, assuming they don’t have someone browsing Internet forums looking for consumer complaints around quality issues.

"DEPENDING THE ENGINE CONDITION" It doesn't say cold start, that was a(n) (logical) assumption.
Read what it says. I magnified it for you.
Maybe it's to let oil or coolant circulate, who knows. Like I said, I didn't engineer it so I don't know the parameters. But obviously you do
You can open a million tickets, it's in the manual, and therefore a properly designed function. Not a defect.

I need to check my user manual for that for my 2020. I have never experienced this problem."DEPENDING THE ENGINE CONDITION" It doesn't say cold start, that was a(n) (logical) assumption.

I could see toyota/bmw limiting the power and rpms if the engine was cold and not started for over 12 hours. What I don't think would be normal is if the engine was at operating temperature already then starting the car and having no power. There would be zero reason for that. The oil is hot and thin so it will get to all needed lubrication areas very quickly.
Coolant flow I'd highly doubt that being a reason to keep the car from reving. Flow would be established in the critical areas of the engine within 1-2 seconds. Also I would think if it had some sort of mechanical failure for coolant flow it would pop up a code.
What I would be interested to see is what all the sensors are reading before starting and during running to see if anything is reading out of parameter. Also knowing what electronic control modules are tied together that manipulate your fuel and spark timing.
I'm not a b58 engine expert, but I do work on heavy equipment that cost more than 100 times the price of this car. It's amazing what one bad sensor, one bad connection, or improper ecu configuration can do.

Ah now I’m seeing what you’re talking about."DEPENDING THE ENGINE CONDITION" It doesn't say cold start, that was a(n) (logical) assumption.

Lofl. You’re literally going to bat on ambiguity on behalf of Toyota. You don’t know the engine condition they require. Your assumption is as good as anybody else’s. You’re taking liberties with their verbiage. Dude. Wow.
It’s a problem that at the very least needs clarity.
Cold start, warm start, issues abound. Lame.

Jesus Christ you're thick.... How much more clarity than written in a manual do you need??? A phone call from Munich? FFS. Be happy your car works as it should.

Yeah it’s everybody else misconstruing the two sentences in the manual you take as end all be all.. Jesus.
Done w you. You don’t know what the hell you’re talking about. You’re happy with your car. Move on and stop contributing when you have nothing to add.
Let the rest of the adults talk it out and get clarity.

Happened to me twice. Seems random
BUT, each time i had been working on something with either hood open for long time or drivers door open long time.
My older m3 i still have is really picking about hood open etc
Some old BMW code floating in there i am guessing

I do not want to become part of this argument and I have not experienced this on my 2021 yet. Only had it a few weeks though. However, I'm curious. Is this a problem only in that we are not able to rev the engine while sitting in park (or neutral as well I assume) or is anyone experiencing problems where you can't get any power once under way?
For me personally, I never have and can't think of a reason I would ever want to start my car and immediately rev the engine. Cold start, warm start, makes no difference. Just not something I would ever do. I think it's entirely possible if my car's ECU was doing what the manual says, I would not notice it. I start the car in my garage. It idles for a few seconds while I put on the seatbelt, get car play going, etc. and then I slowly (often just on idle power or at most barely any gas) back out and down the driveway. It's then another probably 30 or 45 seconds of slow acceleration out the to the main road. The car has probably been running for two minutes or so before I really have to give much gas at all. By that time even if this "protective program" had been running it should have ended and I probably wouldn't realize it was happening. However, if I had no power and it wouldn't rev once I needed to get on the main road and into traffic, that would be a major issue. Has anyone had such an issue?

If your car was experiencing the issue you would not have the ability to drive it regardless of how easy you are. I’ve never attempted to put mine in drive and drive off after I’ve seen this happen but I highly doubt you could if the problem was there. It has a complete lack of power and ability to rev. The op in here posted videos that show the lack of power.
I’m not running to Toyota just yet. I’m perfectly willing to think it’s protective programming in the car or some combination of something I’m doing, and honestly I hope it’s me lol. Again I’ve only had the car a week and it barely has 300 miles. It’s just the manuals explanation does not explain what it’s doing and for how long. Also in my case the car has always been in park and operating temp.

in my case i did not attempt to rev cold. never have. Both times car was already warmed up and i had been messing with something and a friend or someone came by and wanted to hear how it sounded. even when warm i am not a red line guy. just a couple blips to 4500 was my intention. both times the hood and or door was open.
never had it be a problem when i have wanted to actually drive somewhere.
