ERROR CODES on App, but not dash

You should've been a comedian, instead of a film critic!!!
Interesting that they put a data logger into the car, I wonder why they never offered to do that with my car. I had emission failures, dynamic mode failures, all-wheel drive failures, you name it. I also took pictures of the warnings, however the service advisors never showed any interest in them when I told them about it.
Good luck and hopefully your problems will get resolved.

Steering is Rack & Pinion. Please see https://nsx.acura.com/explore/engineering under “Body/Suspension/Chassis”
(have to admit, I thought it was some hi-tech system. But it *WAY* isn’t.)

It uses a bird on a wire system.
More error messages. Frustrating.
Happened again. Received even more error messages on the App, but not on the dash. This is cause for concern, because it’s the same chronology of events that lead me to have to call a flatbed and get towed to the dealer.
Does anyone else else ever get error messages like this on their NSX App or dash?
If these messages are are intended to convey an air of seriousness and immediate concern, then....mission accomplished.

I’d really love to see this too. When someone throws down a whole paragraph of them being a real rocket scientist and all that to add some weight to their statement, surely they must know what they’re talking about right?
OP, not to derail your thread with this silliness, but you’ll want a seat in the peanut gallery for this. It’ll be a good one. Because I really 100% do in fact know what kind of steering system the car uses. My job is not rocket science. My job is knowing how this car works. Speaking of which, hopefully your car is at a dealer and they are figuring out the root cause of your Christmas tree of warning lights.
’Master, thanks for your concern. I ran it hard yesterday, and I’m going to stop by the dealer today to upload the telemetry. But so far, no reply at all from Marysville as to why my dashboard lit up with a half-dozen serious error messages, and why I lost power so abruptly.
Unrelated, but I’ve got to share this with the group: When I absolutely STOMPED on the binders prior to corner entry yesterday, I noticed that the transmission up-shifted from 5th to 2nd in just two shifts, placing me in 2nd at the apex at about 5,500 rpm....PERFECT to power-slide off the corner. And it did it in a way that didn’t upset or change in any perceptible way the brake pedal feel, or the angle of attack, or the weight distribution, or the steering.
Can the transmission physically do that? — up-shift three gears in two shifts? If it can’t, then it’s even MORE amazing, because the three shifts must have been performed lightning-quick.
Either way, that transmission is just stunning!!
I agree with you on the transmission...... Absolutely amazing how it shifts and functions..... It's like the car intuitively knows what you intend to do. I suppose based on throttle and brake input, the computer can figure out what is next..... I have not yet been on the track but have plans to do so in the next few months. Looking forward to see how it all goes.
Pretty cool to have a car color named after a racetrack corner (130R). Hey, Acura: Make a “Corkscrew Silver”.

Marysville has no answers yet because Marysville is awaiting answers from Japan.
Depending on what state you live in, you may qualify to join DOC to rattle-can your car yellow.
Reasonable Repair Attempts
You must allow the dealer or manufacturer to make a "reasonable" number of attempts to fix a substantial problem before your car is considered to be a lemon. Usually, you must meet one of the following standards to be protected under a state lemon law:
If the defect is a serious safety defect—for example, involving brakes or steering—it must remain unfixed after one repair attempt.
If the defect is not a serious safety defect, it must remain unfixed after three or four repair attempts, though the number varies by state.
If the vehicle is in the shop a certain number of days—usually 30 days in a one-year period—to fix one or more substantial warranty defects, it may fit the definition of a lemon.

And yellow is supposedly a new color for 2020.

I feel like something got lost in translation from your service advisor. There’s is no reason ever I’d call “Marysville” which I assume they mean the PMC, to fix a mystery problem with the NSX. I would be calling Torrance where the auto engineering techline is.
But you had a ton of warning lights on, took it to the dealer, they scanned it, and got absolutely no codes? That just does not compute for me.
Do you have a JB4 box installed in your car?
‘Master, I can only tell you that my Dealer technician (an NSX Specialist) said he “reached out to Ohio.” In fairness to him, maybe he was just saying that as some form of shorthand, so as to placate an only-slightly-informed Acura consumer....?
No modifications whatsoever. All stock.
I learned two valuable lessons from owning a Jaguar XJ8-R: (1) ALWAYS take pictures of the dashboard error messages, in case anyone challenges whether any dashboard error messages actually ever appeared; and (2) don’t own a Jaguar KJ8-R.
From my posts above, you can can see all the errors on my dash. After I got towed to the dealer, they said that no error messages AT ALL we’re stored in the car’s brain. None. Not one.
I’d love for you to look carefully at those error messages, and tell me what you glean therefrom. I don’t know what to make — if anything — from either the absence or the presence of those little idiot icons and idiot lights in conjunction with the actual messages.
The most concerning issue, though, was how VIOLENTLY the steering shook after I lost power and pulled over. I never shut off the engine or took it out of gear. I did, however, try to switch from Sport+, to Sport. That’s when I got that “Dynamic Modes Unavailable” message. As I eased up to speed (trying to limp to a safe pull-off spot), the steering shook badly, and it got better/worse with speed. I only managed to go about 22mph — anything over that speed, would’ve shaken the fillings out of my molars.
I have run it HARD since then. No problems. Of course, there shouldn’t BE any problems on a “Ready for the Track on Day One”, brand new NSX.
[I have to say: The way this car slides so utterly predictably, and the buttery-smooth way it just ‘melds’ back into full traction...if this were a Huracán, I would’ve wrapped it around a tree by now.]

Unfortunately, since about 5 years now, the our vehicles work this way now. When a malfunction is detected in a particular system and triggers a code to store in that respective control module, other control modules on the network see that there is a problem in another system, and then those control modules set codes. Codes only to indicate that there is a problem in another system.
So here’s a hypothetical scenario. A small piece of debris finds its way into the air flow sensor. A code is set in the PCM for fuel trim. Soon enough, another control module on the network sees there is a fault with the PCM. More often than not, the first control module to tattletale is the electric parking brake. Then usually the SH-AWD cries wolf next. And electric power steering and ABS/VSA usually raise their hands too. The end result is a dashboard that’s got a ton of lights on. When someone like me connects the Honda Diagnostic System to the vehicle and scans all the systems, it will show me the fuel trim code for the PCM, then the codes stored in the other systems all essentially say PCM malfunction.
That’s why I find it odd that absolutely no codes were stored in your vehicle. There should have been plenty. Even if most of them said nothing other than there was a problem in another system. A warning light comes on? A code gets stored for whatever system that light is attached to. It’s not an absolute though. There are ways that all the codes could be wiped out. If the 12v battery completely died for an extended period of time, then all the control modules would have had their memories cleared. This would have able to have been checked by the inspecting technician by seeing if the OBD monitors had been reset. Another possibility is that there is a communication issue that is interfering with the CAN network. Which is why I asked if you had the JB4 tuner, as I know it can potentially hinder CANbus communication.
Really? It happened to my car on multiple occasions, and an owner in NY I think just got his car bought back because of the same issues. I too, like the OP always took pictures of the messages to show the dealer. Oh, all this happened before my current fiasco when the car had less than 3000 miles on it.
Something is amiss with these cars that the service departments on the local level aren't able to handle. Another reason why this car is not something to be owned after the warranty expires. And it's the main reason why I would never think of modding this car. Not even different brand tires. Acura installed the new Conti 6 in December for me and I haven't put even 75 miles on them.

I can diagnose and repair these cars just fine whether there’s a warranty or not. As I said in your Napleton’s thread, not all dealers and their NSX techs are the same. An unfortunately for you, you’ve managed to find a couple of incompetent ones with your situation.
Based on your experience, and seeing threads like this, one might think these cars are overly sensitive, way too complex for their own good, rolling disasters waiting to happen that apparently need PhD level mechanical engineers (but not rocket scientists maybe...still waiting for that guy to reply) to understand how they work. While they are built very different than other Hondas, it’s still just a car. Other high line brands (M-B, Porsche, Audi, etc) make vehicles with just as many computers on board if not more and require just as much competence if not more to work on them.
And plenty of NC1 owners have not only thought about modding their car, but they’ve gone ahead and done it. Quite a few cars out there now with downpipes on. Gotta be at least 100. Lift systems, engine tuners, and now methanol injection setups are out there too. Those are all jobs not for the faint of heart, yet I believe there still is only one case (that AHM knows about at least) where mods may have caused problem. So there is obviously people out there who know what they’re doing with this car.

You and one other NSX tech seem to know your stuff. It’s too bad someone like you wasn’t available to fix my car. I’m glad people are able to get more power out the car, but I don’t have spare money laying around to replace a $75k engine if it blows up. Furthermore, the quest for more power is a terrible addiction. Been there, done that. Now I’m a recovered addict. OEM is fine for me. Right Jinks?
I’m going to ask my tech about this. But no, the battery was st all times 100%, and no mods whatsoever.
The tech is with you: It’s really a mystery as to why no error codes were stored in the brain.
I also agreenwith with you that there’s lots of ways that a single (and relatively minor) error, can cause a cascading effect, and bring in, as it were, other non-malfunctioning systems to also report errors.
I cant wait to update you, once they give me a solid answer.
I do have some advice for you, but you’ll have to PM if you haven’t blocked me already.
