I have 2600 trouble free miles on my NSX since Dec. of 2017. I have an annoying rattle in my dash/windshield pillar area. Some day I will take it in to be fixed. I had the gas tank recall done. I was told 1 car had a tank issue and Honda decided to recall over 700 cars to change out the tanks. My car was a late enough build that the faulty rad caps and upper brake light issues had already been resolved.
But, with regards to reliability, consider the following:
In 2014, Porsche issued a recall for 785 GT3"s for complete engine changes because there was a threat that the cars could catch fire and burn to the ground. Later in 2015 and into 2016 more cars were recalled for engine replacements because they were blowing up. Valve train issues I think?
McLaren...... Based on what I have heard and researched, perhaps the most unreliable supercar on the market, if not ever. Their problems are well documented. Matt Farrah's comments are interesting, the electrical systems are suspect, and lots of them have caught fire..... At the Formula 1 gran Prix of Austria a couple weeks ago a McLaren was doing hot laps on the track and it caught fire. Luckily the track workers were able to get the fire put out. Brutally fast cars with less than impressive styling, but I wouldn't own one if you gave it to me.....
A buddy of mine bought a brand new 2018 Audi RS3 last year. $65K, and a great little car. After 3 months the car wouldn't start. After 2 months at the dealer, they could never get the car to start, so Audi America decided to take the car off his hands and give him a new 2019..... 3 months later, the car finally has arrived at the local dealer where it sits in it's shipping wrap while Audi tries to figure out how to swap titles......
And other British cars?? Aston Martin?? No thanks......
My son owned a BMW. It was out of warranty and it broke, or leaked, or fell apart on a monthly basis. It was a piece of shit..... German technology at it's best.
I hear Ferrari's are more reliable than in the past. But I personally could not afford a $350K car much less the $20 K per year to maintain it. I suppose that if you can afford the car's cost, then you likely can afford the maintenance....... There is an adage that says to never buy a first edition car. Wait for the following years after the manufacturer has had a chance to work out the bugs. Maybe this is true with the 2017 NSX. As someone said earlier, there seems to be no issues with the 2018 and 2019's.
Part of the reason I ended up buying the NSX (aside from the $43K discount) was the "perceived reliability" of a Honda product..... When it comes to reliability, based on the above examples, I'm not sure the NSX is in the top 5 unreliable cars..... ALL cars are overly complicated and expensive to fix. There have been "fears" of the cost of replacing a blown NSX engine out of warranty..... Is it any more than what you'd pay for an out of warranty Ferrari or McLaren??? This is why you rarely see a Ferrari with more than 10K miles..... I had circumstances that allowed me to buy an NSX, and I have to say that I have had a great and unique experience thus far...... It's not a car for everyone, but something different, unique and low production......
