But to be honest, if I lived in a large city where parking may be difficult, I would not have a C8 as a daily driver. I am lucky to live in an area where I have no real concern driving around in my C8.

My newest vehicle is a 2014 Mazda 3. It has never had software bugs, despite the fact that it has the tech package and super capacitor. My wife's vehicle is a Lexus hybrid. Again, never a problem.
Consistently throughout the years, Toyota/Lexus and Mazda have ranked at or near the top of manufacturers rankings for most to least overall reliability. GM is always among the lower half.

Why don't you tell the truth and just admit that you are one of those types that hates everything "American" and just knows that everyone else in the world does it "better" ??? Japanese cars? BETTER! European cars? BETTER!!! Korean cars? BETTER!!!
Any device with millions of lines of code has bugs. Whether you want to admit it or not.

I used to hate everything about American cars until……….the C8. Now I naturally keep an eye on GM vehicles. I’m very impressed with the Blazer (petrol & electric versions). My neighbor has a Silverado High Country and it’s hella plush. I went on a ride and didn’t want to get out of the truck

I’m not sure how a sticky for real world C8 problems turned into a manufacturer discrimination thread
Now with that said, I’ve had a wide variety of makes and honestly GM has surprisingly been near the top and I have no reason to choose one or another brand.

I was a long time Porsche owner. Ordered a 2022 C8 because I truly dislike the Indigo group who bought the two local Porsche dealers and combined them. Since the purchase the whole feeling at the dealership has changed. They are generally very arrogant as a whole and treat you like they are doing you a favor selling you a car and servicing it. They also built a new Ferrari dealership right next door. Life’s too short to deal with that kind of attitude just to have a car. Porsches are good cars but I have choices where I can get my C8 serviced. Sam

2024 C8 of the Year Finalist - Unmodified
Ridiculous. I've had one Corvette out of the five I've owned - a C6 - that I would consider problematic. I realize there are thousands of C6 owners out there with zero problems. My other four Corvettes have only needed normal maintenance in the 30+ years I've owned them.

The problem is newer vehicles are exponentially more prone to issues, so comparisons with the past are not really valid IMO. But talking about the present, and the DCT in particular, even BMW shied away from those even on M cars, due to the extra complication, lack of reliability, and most importantly, the newest torque-converter autos shift just as fast, while being dead-stone reliable. I drove one, and couldn't even tell it wasn't a DCT, and I owned a PDK Porsche not long ago. So not sure why GM decided on a DCT, especially from a newcomer, knowing there would be a lot of issues the first few years. Porsche still uses it, but the ZF is miles ahead of Tremec, due to 15+ years of being in the market (vs 3+). Plus a lot less maintenance requirements (officially, every 120K miles, or 12 years). Hopefully GM/Tremec made other changes for '24, along with the new case, to improve reliability. I'll be watching for that.

Good luck finding a torque-converter auto transaxle for a mid-engine configuration with enough gear sets...then out of those, if there are any, find one that can handle the torque of the LT2.

And that has the input shaft on the bottom and output shaft on the top to allow lower mounting of the engine/transaxle.

The worst ever car I bought was a Toyota Corolla. We bought it new, I think a 1986 or 1987 model. The car was the last year they were carbureted and the engine never worked right, but that was not the worst problem. The windshield was not glued like it is now on most cars, there was a rubber gasket around it but it was apparently not supported at the bottom so it slid down over time by about an inch such that there was a 1/4" gap at the top with the roof so that rain entered under the roof. It sounds incredible but that happened almost immediately and we dismissed it and only realized the damage after the warranty period was out. The entire roof and A pillars started rusting from inside, bubbling the paint and it rained in the car. We got rid of the car after 3 years for a song.
I believe they were made in Mexico.

Consumer Reports has consistently ranked GM well below average for reliability throughout many decades. Toyota/Lexus has always been among the top three. Our 2006 Lexus RX400h, which is not simple, technologically by any stretch of the imagination, is now over 18 years old and has never had a driveability issue related to mechanical or electronic failure - not one. We really are spoiled, especially by its reliability of electronics. Yes, this is also just one example, but I can assure you that no Lexus forum has an issues folder that is anywhere near as lengthy as this one.
But we all have choices and thus risk in whatever we buy. Good luck with your C8. I honestly hope you don't go through what I did with GM products..

I once read about a 100 years old man who smoked cigarettes, yet lived a good long life.

The thing is that this model has only been around since 2021.

Other configurations are: IS lineup for 2024. IS 300 grades come with a 241-hp 2.0-liter turbo-4 and the choice of rear- or all-wheel drive. IS 350 grades come with a 311-hp 3.5-liter V-6.
$41,235 for the IS 300, at $44,410 for the IS 350 F Sport Design, and at $60,020 for the IS 500 F Sport. The most expensive grade is the IS 500 F Sport Premium, which starts at $64,520. All figures include a $1,150 destination charge.

My daughter had a Lexus. Biggest POS I have ever seen.
At least they put the BIG L on the front for LOOSER.
Finally lemon lawed it and she got a Chevy Malibu. Sold it with 160k miles. Still see it driving around.
