I heard that the NA rotaries in the FB and FC RX-7s are actually decently reliable as long as it's been taken care of, while turbocharged FC/FD are the issues. RX-8 had to compromise a lot for emissions and so it had its share of issues as well.

They are fun cars if you take care of them and can get over the gas mileage(which is worse than a Corvette's). And honestly, even without rotaries, Mazda has a lot of problems to solve. They need to figure out like how to market their products properly...

But heh, at least rotaries won't have valve spring issues!

First and second gen RX-7's, I did not have major issues with but to your point it is a very hands on experience. You have to check the oil after every spirited drive and everytime you fill up with gas (which is a lot). And you just don't question adding several quarts a week or month depending on driving frequency. Unfortunately most people don't maintain their cars that way and so lots and lots of issues. My FD (twin turbo) RX-7's were also very high maintenance and while I did not have issues I was accustomed to checking and adding oil almost daily.

By comparison the LT1 is a much easier engine to maintain Not that I don't check the oil on my car regularly, but certainly not daily or even weekly. My C7 was very solid, no issues with any major component. Actually no issues at all except for some substandard paint, but paint issues plague just about every manufacturer now due to environmental concerns.

I don't know. Failing apex seals or broken valve springs? Well, at least you can still drive home with the failed apex seal without damaging the engine, I guess. Problem is, one is going to require an engine rebuild while the other is just replacing a valve spring after you remove the valve cover.

That means my new 21 ZL1 1LE, built on August 8th... that I haven't even picked up yet could have bad valve springs.... AWESOME

My LS3 had one valve spring replaced under warranty and another broke just over a month ago. When the second one broke I paid for all of them to be replaced as I'd like to keep this car forever.
If you have a broken valve spring replaced under warranty I'd suggest paying to replace the other 15, if you plan to keep the car for a while. I tried to make the case to have them all replaced when the first one broke to no avail. I was actually pretty pissed when the second one broke but the dealership isn't reimbursed for replacing parts that aren't broken so I kind of get it from their side.

What's confusing is for the C8 they seemed to highlight replacing all the valve springs, but for all the other vehicles affected it is to just replace the broken one (s). Odd..

Wow just dodged this one (I think). Car was built on 9/21 or 9/22 this week.

They say to replace all the springs on the 6.2 L87, LT1, LT2 and the LT4

In fact, just 2 simple issues over that time that were promptly taken care of via warranty. It's really sad. The Corvette is Chevy's most premium vehicle but reading all of the ticky-tack problems and issues they've had with the new C8 proves my point. I'm so happy that I didn't even try to obtain one. I know some of the issues have to do with the first model year thing but they can't even get the stitching straight on the dash and seats. If you want people to pay for a premium product, you must produce a premium product.

Bullshit. Every car company has had problems. Every. One....

I do it all the time!! Lol.

In 1966 I bought a new ss396 Chevelle. I had to carry a roadside valve spring repair kit because the springs broke frequently. At least they were easily accessed back then.
ALL manufacturers experience parts problems. Hell, some tires even go flat from time to time. Not too often but it happens.

I had a 2010 that had some sticker lifters. Until the car warmed up one hell of a knock. Didn't show until 15k miles in. Was out of warranty at that point cause if had it for 6 years.
