Engine failure on a 2017 Grrr

[Spoolinfool]

If you have warranty I think there's nothing to worry about but those without warranty should purchase some form of aftermarket warranty since the engine is so expensive. It maybe pure speculation but at one point more than 5 used Nc1 engines were available on ebay which have since dissapeared meaning people have been replacing engines we just dont know for what circumstances they are being replaced.That combined with the fact that acura parts websites do not show the nc1 engine short or longblocks available for purchases makes me wonder if pmc is holding all inventory to fulfill racing program and warranty cases first.

I don’t understand your reasoning that the ones for sale disappeared because they need new engines?
Maybe they were sold instead?

Yes, Im thinking the used ebay motors were bought to repair cars that weren't under warranty or had warranty that was voided because any car under warranty would have had a new crate motor come from pmc instead.

So people or pmc are buying up used nc1 for parts to replace engines for other nc1?
can look at the carfax to see where they went if a new owner registered them if not then maybe you theory is possible.

Think I’ll be staying stock. Had a modified GTR that was fast but frustrating. Gradually blew it up. Rod and clutch. I run all seasons and drive busy roads, so it would only be project / ego anyway. Kinda pissed me off when a supercharged ram truck was hanging with me on straight line though. And impressive.

Curious how much were those eBay motors?

They were around 8 to 15k depending how complete. Bare long blocks were around 8-9k and complete accesories like oil tanks and turbo were closer ro 15k-20k. At one point they had a few with transmissions still attached for around 36k to 40k .

There are a couple on eBay now. ~$7.5k and regularly dropping in price. Interesting to note that there are very few differences in part numbers from 2017 to 2021 as they relate to the JNC1. Differences I could find were the VTC oil control solenoid valves, transmission synchro sleeve/hub, and secondary fuel pump/sender (which is a known point of failure in early models). It would seem that whatever modes of failure the earlier engines have succumbed to were either isolated incidents or maintenance related, or all JNC1's are at risk for the same failures.

I think they are generally reliable atleast the mechanical parts.The only parts I heard failing were oil system failures and headgaskets in tuned cars driven hard.

I agree, I still cannot under why people try to heavily modify these cars.

Also how "common" is this?Science of Speed stated they have already done a motor swap from catastrophic engine failure for a customer and the dealership today stated there have been 10 different NSX's this year that have gone to numerous dealerships so far that have had engine issues all with the same symptoms..

WHAT? This is the first time I am hearing about 10 NSX's with engine issues. Dealers will cay anything, so im not sure how credible this information is.

For a power plant that has undergone a decade of development and also in nearly identical form competes in professional motorsports, I am doubtful it is failing with noteworthy frequency. I would however like to know more about the common modes of failure, should that information become available.

Guys I have a 2017 Acura NSX with 59k miles on it.. She has always had oil changes done at the local Acura dealership... I have owned the car for 3 years now and had no issues other than a leaking left axle.. There has been no modifications done to the car. After driving it the other day it sounded like a big clunk came from the rear of my car and all ignition lights came on, it would not even let me go in electric mode. It got towed to the dealership and they have looked at it for the last week and have told me the engine has seized!!!!! WTH !!!! Where do I stand with Acura on this?? The car does have a prior rebuilt title from a small front end collisions 5 years ago when she had 11k mile on it and way before my time.. I just don't understand why a NSX with plenty of oil and regular service would have catastrophic engine failure.. I'm really sad right now
Please help on any advise
