Searching through C&D looking for it, all I found related to heat management on the non Z06 is... https://www.caranddriver.com/reviews...-drive-review/ Quote:
I have way more faith in Corvette than BMW. BMW hasn't made anything I have any desire for/interest in/desire to work on since they moved to turbos. By more easily serviceable I meant the engine is easy to access from above-- routine maintenance, such as valve cover gaskets, spark plugs, coils, etc will still be easily accessed (with some caution not to mar the paint). Compared to a Boxster/cayman/911, with no topside access and turbo components adding complexity everywhere, should be a cakewalk. Or, put differently-- the car is set up so that Chevrolet dearerships will be able to work on it!

I'm not sure this qualifies as 'a few teething issues'. It's easy to picture the Vette people coming out to defend that this was just one car, that blah blah blah. Mags have had the E46 and E9X and somehow neither of those has had vanos/subframe/rod bearing issues. https://www.caranddriver.com/reviews...-test-wrap-up/ Some choice quotes Let’s get this out of the way up front: The litany of breakdowns suffered by our long-term 2014 Chevrolet Corvette Stingray Z51 (C7) was simply appalling. But the dry-sump oiling system included with the $2800 Z51 package could not prevent the engine from self-destructing. It grenaded at 6000 miles, when we rolled onto a local chassis dynamometer to meas*ure the LT1’s power at the pavement. The engine started to eat itself before we could begin the testing in earnest. Other drivers agreed, chiding the seven-speed for its chunky engagement, propensity to pop out of lower gears, and the difficulty in navigating the tightly spaced gates. Although we had fitted excellent Michelin Pilot Alpin PA4 winter tires, the Corvette struggled in the deep freeze of our Michigan winter. In sub-zero temps, the LT1 V-8 could take up to 12 seconds of cranking before firing, which surely contributed to the starter motor dying at 21,000 miles. Shortly thereafter, the brain of the Stingray’s heating-and-air-conditioning system began shutting down intermittently—in mid-January—and needed to be swapped. The C7’s axle seals began leaking lubricant at 25,000 miles. Frigid winter weather probably aggravated this failure. GM was in the process of installing more-durable seals in production, and the improved parts supplied to our dealer cured the issue. But it’s worth mentioning that neither our long-term 2014 Jaguar F-type V-8 S nor our 2014 Porsche Cayman S, which both suffered through the same awful winter, had any problems dealing with the cold. We’ve experienced little if any trouble with the later Stingrays we’ve driven and want to think of our test car as a first-year anomaly. The latest Corvette is an amazing performance bargain, and it still pained us to hand back the keys. But the reality is that this Stingray failed spectacularly, and its 17-month evaluation was a test of our patience as much as it was of the car itself. We can forgive some of its troubles because the C7 is the type of machine we’re happy to still have in our over-regulated and increasingly automated world. But we won’t forget this experience anytime soon. And about the regular Z51 C7 overheating, it was in Edmunds, my bad. Sometimes I confuse both mags. Here's the link: https://www.edmunds.com/chevrolet/co...g-checkup.html https://www.edmunds.com/chevrolet/co...tain-road.html Which mates up perfectly with what I read in the Vette forums when I was thinking of getting a C7 Z51 instead of the E90 M3. The first condition in my mind for a car to be considered an option is for it to function. The QuattroFormaggio may drive like a dream and yadayadayada, but as it cannot function without breaking down then it's not a real world option. So we can talk about fun to drive and EPS and turbos and whatever, but a car has to be able to function. I couldn't care less how engaging something is if it doesn't work. |

Why do you think the edmunds corvette is a Z51? Neither of those links mentions it being a Z51? (Z51 being relevant as it adds almost all the important cooling for hard use)

Ive had a number of Corvettes. GS, multiple Z06, etc. C4, C5, and C6. Then I got into Porsches because VAG has the best interiors in the business.
I never had a single substantial problem in 16 cumulative years of track use, autoX use, heads-cam-headers-in-the-driveway, daily driving, etc etc. As a reference, Ive had this M3 for 20k miles and Ive replaced the rod bearings, transmission seals, an oil pan, several sensors, and (in my opinion) the front calipers needed replacing with aftermarket after the second track day. The C8 with Z51 will be an incredible bargain and faster around a track than any stock BMW, but the interior will likely make me sad. Also, if you have to wonder about 911s, then I can't explain it to you I love what I have and I am always planning the next one. They are just simply superior cars. |

https://www.edmunds.com/chevrolet/co...roduction.html I don't think the Z51 package is relevant in the very least. They did not overheat while running slicks at a track day. They overheated after 8 turns in a 'mountain road'. Again, a car needs to function. Overheating after 8 turns is solidly in the 'nonfunctioning' spectrum of things. You should not need beefed up cooling to withstand driving on mountain roads. But my philosophical qualms are unnecessary as the car indeed did have the Z51 package. Yes yes, I know it's a suuuuuper common failure on the E9X... so common in fact that neither C&D nor Edmunds, nor Motortrend have blown an E9X engine... or throttle actuators, or crank hubs in the F8Xs they've had... but these guys blew their vette's engine. Apparently deburring is really hard to figure out especially when making an engine that's brand new... oh wait... Car and Driver blew two Z51s if I remember correctly. Please don't ask me to post the links. It is a waste of time. Before telling me that Z51s do not overheat people should have done their homework. It does seem like the GS is the sweet spot in the Vette lineup and functions correctly. By the time it came out I was too turned off at the idea to pull the trigger Last edited by SYT_Shadow; 08-02-2019 at 06:26 PM.. |

I suspect the list of people that think that (a) the LSX/LTX is unreliable or (b) the s65 is reliable... is very short.

I suspect only the Porsche GT/Turbo variants have better reliability than Ms. Their base models are known for disastrous oil starvation on high lateral G applications. Ah the flat 6 engines...

But that's what 100k plugs are for. Definitely looks like they expect you to reach everything important from the bottom. You're not getting access to much from the top without standing in the golf club/lawn chair/car show/zaino/gold chain/trophy compartment behind the engine AT LEAST THERE'S A MOT@!6*)(Q36!##6$!6$iING DIPSTICK

Also, I forgot to add in the the expenses of owning my S65 the $300 extra I spent on adding a dipstick. At one point I had an old Chevy C10 truck and a Volvo V70R. One of the cars in my driveway had wheel bearings that only lasted 30k miles, and it wasn't the 50 year old one made of soft iron. The dipstick thing reminds me that my 1968 Chevy C10 had a dipstick. |

You were lucky! Our V70R ate a left rear wheel bearing at 14k miles. ...and that was the 2nd V70R since the first one Volvo bought back from us due to all its issues they couldn't fix. The 2nd one lasted 11 months before we sold it with 16k miles to get rid of it and Volvo for good shortly after experiencing ABS ice mode on dry pavement trying to stop hard going over a bumpy road.

Bumping up this thread, I saw my first c8 today in real life... a white one, I was in awe of it's presence, coupled with the praise it's received In today's media I'm very impressed, I want one... had anyone driven one yet? Thoughts?

Lots of quality control issues popping up in online reports: wavy dash stitching, seat material buckling, panel gaps, chipped paint due to wheel liner screw being too long, trans leak, failed DCT...
