Seems like more transmission issues are popping up, if what's being posted in the Facebook groups is to be believed.

Obviously every car has issues, but I'd be lying if I said that this isn't starting to give me second thoughts about placing an order since putting a deposit down in December. I know everyone says "that's what the warranty is for", but this seems way more common than it should be. Warranty be damned, it still a headache and a pain to go through that entire process.

Anyone feeling the same, or am I crazy for feeling like this?

I'm a numbers guy. They have made over 40K C8's so far, which for a relativity expensive 2 seater sports car, that is a lot. To understand how bad these transmission issues are we would need to know how many? Is it .001%? .05%? 1%? 5%? etc of all C8's produced? Also keep in mind there are TSB's already out there that address some of the complaints (like jerky transmission). So of those how many require a full replacement?

And then you have the fact that most people don't post when their transmission is fine, you just hear from the problem cars.

LIke?

A lot of folks have never driven a DCT-equipped car, and are used to torque converter automatics, which are smoother. They may perceive problems that aren't.

The C8 Tremec DCT appears to be relatively reliable, although a small number have experienced issues, which software programming usually resolves.

Over 40K???

* 2020 - 20,368
* 2021 - 12,971 (as of yesterday’s report)

I'm only seeing 33,339.

Oh, I saw some numbers from the BASH event that said 19K+ 2021's, but I bet all those cars have not been built yet?

Not going to get much sympathy over here on CF :-0 It's funny you posted as I was thinking the same thing just last week as I was surprised at how many were popping up that were recent builds .... not the early ones.

I agree that out of the 30kish cars built so far, this represents a very very small fraction which is definitely inconvenient for the owner but maybe within acceptable limits for a new model/tranny Since people are always more vocal about complaints than compliments, it is more in your face but I don't seem to hear about these issues as often on my other expensive vehicles that are in the 60-90k range.

Hopefully the numbers (and posters) will continue to drop as I'm sure small tweaks are happening on the back end every time they learn something new.

I look at it this way, even out of warranty (if I keep it that long) will be lot cheaper than replacing a PDK on a 911.

JVi

Cheaper to fix a C8 than a 911 PDK but it won't be if the the DCT breaks 2x the frequency of the PDK.

It sure would be nice if the car had a dip stick for the DCT.
To keep tabs on the color and smell of fluid......

Had my 21 HTC since Dec 2020. Have 2000 miles on it now. I've done at least 20 launches and have been known to enjoy a bit of "spirited" driving. I also took the Ron Fellows course in Nevada in March. The 2020 coupe I drove, felt exactly like my HTC even though it was a Z51, which mine is not. In short: The cars at the driving school get the crap driven out of them on a daily basis. If the DCT in those cars have been holding up for 7000 miles or so I have no worries.

As a matter of fact I think the people that seem to have the most problems are those that have had the car for over a year now and still haven't gotten to 500 miles yet. A car like any machinery is meant to be used and not sit around. The worst thing you can do to a car is to simply let it sit rust and dry rot. My humble opinion and not that of the management.

A DCT is going to be expensive to fix or replace whether its the C8 Tremec or the Porsche PDK. There aren't many shops with the expertise to repair them.

tsigwing

or 10x or 20x, what's your point? There is not data to indicate that the C8's is failing at twice the rate of the 911, or is there?

Most people don't post about problems either. So if you are seeing a higher post on an issue, you can be pretty much guess there are more of these problems out there.

Red Mist Rulz

Still a lot of cars. How many transmission failures is "a lot." I'm sure they exist, but I doubt they amount to a very significant percentage of vehicles sold.
Actually, people are much more likely to post online to complain that to say "everything is fine."

Red Mist Rulz

And you have any data to suggest that will happen?

Didn't think so.

What I am saying is most people don't spend time on forums. If they have an issue they get it fixed without telling the world. Of the people who do spend time on forums yes they are vocal, but probably only make up 1% of the owners, if that.

If you've only driven a typical slushbox with a torque converter the shifts of a DCT are going to seem rough, i. e. crisp. They can also be somewhat jerky at slow speeds and when decelerating. Based on my experience with DCTs in BMWs and Audis it is normal. Software tweaks can help.

Not encouraging news if more cars are having problems, but would really have to see the actual number/percentage of cars that are involved.

The FB posts regarding transmission issues have been MY 21’s with low mileage. There have been 4 the last 7-10 days their dealerships are waiting for parts 2 are replacements. Mileage is below 2,000 miles one replacement reports 400 miles .
