C7 Rated Much Worse For Reliabiltity Than C6 and C5

So the sampling changed suddenly from 2013 to 2014, which just happens to coincide with the model changeover to the C6 to C7? The sampling changed so much that the reliability rating went from the top rating of Excellent which had been holding for years to the bottom rating of Very Poor?
Certainly there is going to be some statistical variation, but statistical variation can't account for going from the top rating to the bottom rating. It would not have held steady at the top rating for years, and then at the bottom rating for years if there was random statistical variation.
Unfortunately, GM management is probably making the same kinds of excuses, and that's why their quality is falling.

I like the rating they gave to the '03 C5, but I've never been a big follower of CR when it comes to vehicles.

M7 is solid as heck But the C7 is in it's final year so a little late to be whining about it's reliability.

I posted this info here a while back and was thoroughly flamed with idiotic 'CR is a libtard publication, eff them' and 'my C7 is solid as a rock' commentary.
1.) CR is the only entity that's ever done a study regarding reliability of ANY size sampling on this car. There's probably something to it, if you have two friggin brain cells to rub together and you can think OBJECTIVELY about it for two minutes.
2.) Your individual anecdotal experience, positive or negative, is not relevant.
3.) Cars in general have become SO much more reliable than 20+ years ago, that I'd argue that even though C7s may indeed be far less reliable than the average 2018 or 2017 new car, they are still probably far MORE reliable than ANY car built c. 1998 including the C5. In other words, the worst car today might be as good or better than the best car of a prior era, so C7s are overall VERY reliable cars in the big picture.
WHY do people here get angry and defensive when GM is called out for making cars that are sub-par by 2018 standards? Not by some hostile editorial board, but by CR's survey results from subscribers who bought the car @ retail. It is what it is. Maybe if GM hears this, they'll make their cars better. If that happens, we all win, including GM. But this idea that this is some pinko commie plot to tear down GM is preposterous. I love the C7, kudos to GM for making such a great car. Now it would be nice if they stop making face palm gaffes like the A8 tranny on these sleds.
After the spectacular job they did with the C7 development and production, Tadge's team shouldn't be undermined by stuff like the A8 fiasco. I'm sure there are suits inside GM that get this, even if some hot headed C7 owners don't.

I was looking at the Consumer Reports Reliability ratings for the C7 vs. the C6 and C5, and the results are startling. Before everyone groans about it being Consumer Reports, the results are based on actual users, not their editorial staff. The C5 had a Very Poor reliability rating in 2000 (steering wheel lock, active handling faults, piston slap, leaking batteries?), but was quite reliable near the end of the run. The C6 was even more reliable in the early years than the C7, and went years with their top reliability ratings after that. Meanwhile the C7 started off with a Very Poor rating, and in five years has not improved at all. Below are the overall reliability verdicts.
2000 C5 = Very Poor
2001 C5 = not available
2002 C5 = Average
2003 C5 = Excellent
2004 C5 = Excellent
2005 C6 = Good
2006 C6 = Good
2007 C6 = Average
2008 C6 = Excellent
2009 C6 = Excellent
2010 C6 = not available
2011 C6 = Excellent
2012 C6 = Excellent
2013 C6 = Excellent
2014 C7 = Very Poor
2015 C7 = Very Poor
2016 C7 = Very Poor
2017 C7 = Very Poor
I checked some other Chevy models. The Camaro reliability has sunk like a rock down to Very Poor with the 6th Gen. The Cruze is in the toilet. The current generation Malibu is going down. The Impala is up at least. My gut instinct is GM is not focusing on quality like they used to. GM has some work to do.

When did GM ever focus on QUALITY

It's one magazine- Consumer Reports. They accept no paid advertising. Their auto reliability ratings are based solely on a survey they send to 400,000 of their 3.2 million (print) and 3.8 million (digital) subscriber base. Any auto reliability data is provided by people who actually own and drive the cars they are responding about.

Okay. fair enough.
How many of you (Corvette owners) have eve been polled by these guys?
NOT me.

I promise, I'll fill it out next year and give the C7 5 Stars.
I pay like $30 annually for their magazine and I find that the info I get from that saves me more than that in making smarter purchases on big items and other info I can't get anywhere else. You have to take their ratings with a grain of salt, but the demonization that goes on here for that organization is 10x more skullfarked than the dumbest **** CR ever did.

I have been polled, multiple times, and I am not currently a subscriber. I did subscribe a few years ago but never did renew my subscription. I am surprised they keep asking me to participate in their surveys. In fact I did one of their surveys about 2 weeks ago.

Do these surveys ask about actual mechanical problems the car has had, or do they get into nonsense like the size of the cup holders, the fuel economy, or how easy it is to use the infotainment system?
The C7 won't hold a Big Gulp, the fuel economy sucks in the city (when compared to a Honda Fit) and the infotainment system is difficult to use if the idea of a "touch screen" scares you. Clearly, the C7 is crap.
For those of us who live in reality, it's a pretty amazing car.

The degree to which half the people here act as if CR conducting this survey and reporting the results is akin to spraying graffiti on the Sistine Chapel ceiling is remarkable. I hope you're all more secure in your own manhood.

If you ever subscribed to CR you probably stay on their mailing list and get those surveys forever. Do your friends here a favor, reply to the survey and check all the right boxes so some of them don't stroke out. That's what I'm going to do. Maybe the two of us can drag the C7 score up a notch and the people here can friggin relax.

Consumer Reports is not to be confused with science in any way. There is no randomization, there are no controls, and they do not reveal sample size. On top of all that, they use terms like “excellent” and “very poor” to hide the fact that the best cars are separated from the worst cars by something like 1 malfunction per 1000 cars.

I've known about Corvettes getting bad ratings from CR on reliability for a very long time. Never stopped me from buying two of them, and it certainly doesn't keep me up at night. And I've had two, count 'em two issues in nearly 25K miles of C6/7 ownership: the C6 needed an alternator and a new battery right after I got it (it was an 8 year old C6 with 20,000 miles on it, the first owner never drove it, the battery kept dying, so that's predictable) and my 2017 C7 needed a windshield washer fluid pump after 8000 miles, the dealer replaced it under warranty in one day. Not exactly stuff that worries me.
That windshield washer fluid pump issue on my 2017? You have GM cars going up vs. Toyotas, Hondas and Subarus that HARDLY EVER BREAK. So of course they're not going to do as well on those surveys. But 99% of Corvette owners won't have that problem. It's just that 99.8% of the other brand owners don't : ).

I have not been surveyed.
I owned my 2014 Stingray 3LT, Z51 7M for four years and two months. I had no issues with the car. I never had any troubles with it, other than having to fill the tank slowly. For a GM product, the fit and finish was very good.
My 18 Grand Sport 3LT M7 is to new to say, only 750 miles on her.
First one was good enough I bought a second.

of the 3+ million, how many are actual C7 owners versus people who heard from a guy who heard from a guy?
