HTC roof issue

According to AI , lol. HTC Corporation is a Taiwanese consumer electronics company, best known for its innovations in smartphones and virtual reality (VR) technology. Founded in 1997 and headquartered in Taoyuan, Taiwan, HTC initially gained prominence as a manufacturer of smartphones, including the first Android phone, the HTC Dream (T-Mobile G1). 
Just to clarify, the first two oil changes as well as the first TX service are included in the purchase price. And perhaps you might want to reach out to @Mr.Corvette for a very good deal on an extended warranty. If you haven’t done so already of course. Highly recommended. And blogs for the most part are questionable information at the best. Depending of course.
There is no official published failure rate for the C8 Corvette convertible top (HTC) mechanism. However, online owner forums and discussions indicate that while failures are reported—such as cable issues, sensor faults, or the top not operating as expected—they are not extremely common. Many owners report no problems at all, especially in newer models.
When issues do occur, they often trigger a “Service Convertible Top” message and require dealer attention, but these seem to be relatively isolated incidents rather than widespread failures. In summary, while the mechanism is complex and some failures have occurred, there is no evidence of a high failure rate at this time.
There is no official statistic from GM, but forum discussions suggest that less than 1% of C8 Corvette convertibles experience cable failures with the hardtop convertible (HTC) mechanism. Reports of cable issues exist, but they appear to be relatively rare compared to the total number of vehicles produced.

Happy, your close with what you said here. DCT at 12,000 and the first transmission fluid change is required at 72,000 km OR Every 3 Years whichever comes first. The GMPP maintenance plan covers both after the first free DCT filter change is done at 12,000 km within 2 years on a 2023 or 3 years on a 2024-2025 model year car. GM sent a letter out in November 2024 to remind C8 owners of the maintenance schedule requirements to maintain your factory warranty.Hello Swaite, welcome to CCF!
Blogs, Smogs, Here in Canada we change our DTC filter at 12000km. and we get it done free of charge.(this little winking guy means I am joking)
All humour aside Swaite, there is no reason that you need to change all the transmission fluid at 12000km, it is only a top up of displaced fluid from the DTC filter removal. Full transmission fluid change is not required until 36000km.
I am sure there is a BLOG somewhere on the internet that states this. Do you actually own a C8 or are you just C8 bashing for the heck of it?
This is exactly what the engineering team told me when I asked them about the failure rate. Great answer!
Much much lower than the failure rate of Trumps policies, lol .
Exactly, 1313 days to go!

You lose almost all your storage space with a coupe and the top stored in the back. That’s why I bought a HTC and love it. IMO the aesthetics were much nicer too in the HTC. I love all vettes enjoy your ride.
Very true. For me in my climate, the HTC didn’t really make sense. Case in point. At 6,065 km I have yet to remove the top, lol. Probably too lazy . Not that we don’t get lots of warm weather. One of the sunniest places in the country actually.
I have had my Coupe for almost 5 years. Drove with the top off once. Wore a hat to protect myself from sun burn. What is the purpose of having a Mid Engine car if you hide the engine. Oh yeah, the people that install plastic covers on the engine bay and then stage the HTC to see it at shows lol...
LOL...I've had both, and there is no comparison...HTC is so much more enjoyable, and when it started raining yesterday, I must say, pushing the button at an intersection was pretty convenient... I don't believe most buy the C8 because of where the engine is located, we don't really have a choice, it just happens to be in the back....
Jack,
When you trade in for the ZR1-X, where will your cooler go, should you decide to take the roof off?
For myself, I trust that the engine is still there - I don't need to see it.
Totally disagree! I bought it for that exact reason. A mid engine sports car! Always wanted one. Had many performance front engine cars. They don't compare.
THIS!
Personally I prefer the look of the coupe, especially from the rear but of course to each their own. Always nice to have choices.
They both have pluses and minuses. I had no choice. They only had coupes when I ordered mine. lol
