He probably only has the stock 14 speaker system. Those additional 2 subs you have under the seat would certainly hide any squeaks

 

Sure, not a problem.

 

Same issue. But it’s so benign I can barely hear it and can’t replicate it on demand. Sometimes the slightest bump will cause it and, yet, I can’t make it squeak by hitting the lane divider bumps (some of those are aggressive) or hitting the brakes.

It’s not intrusive enough to be heard over normal radio volume so it’s more of a gnat bite than a real problem. But I know it’s there sometimes so it irks me.

 

One thing that may be playing a role (at least in my C8), Is that the "BUZZING" is most prevalent first thing in the morning, when the interior of the car is cold (under 40 degrees). Once I have driven around awhile, it tends to go away, and in the afternoon, when the car has been sitting in the sun all day at work, the dash never buzzes on the way home. I think the heating of the interior by the sun, is causing whatever gap materials to "buzz" or rattle, to expand and close the gap.

I guess that if the buzzing really bothers me, I can move to Hawaii....

 

Or turn off the heat.

 

There is an axiom that applies here, that affects engineering, QC, and time to market. There is a significant pressure to produce NEW models because the consumer always wants the latest and greatest, and sometimes greatest just means "NEW DESIGN". They even use this in their marketing slogans, "The ALL NEW Acura MDX!" Ohh crap, I gotta have the ALL NEW one!
You can produce a product that has meets only 2 of the 3 axiomatic principles: cheap, good, quick.
There is a lot of pressure to produce new models quickly, and they also have a lot of pressure to make them cheaply for mass produced vehicles, so that means it is very hard to make them also very good. Everybody likes to mention how good the japanese cars are, but I have owned toyotas and had some significant issues.
My daughter has an audi, that car is full of issues. You would think that with the evolution of that engine, they would have had enough time to work out the design problems.
My mother bought a BMW Z4 that had an electrical gremlin that even the BMW dealers couldn't figure out. (she took it to several shops). I am an EE, so I managed to figure it out and get it fixed, but it was a PITA and was a complex issue because it involved TWO components with issues and a CAN BUS between them.
I think the C8 is suffering from QC related issues from this because they designed/built this thing relatively quickly and the price is much less than comparable vehicles. (I believe Tadge said that the ONLY part on this vehicle that carries over from previous designs is the DOOR LATCH!) All things considered, I think GM did a great job for a mass produced car.

 

Just got a 2021 Red Mist coupe. Bought from a flipper with 4 miles on odometer. Getting to know the car - I see a few dots in the paint on hood that are similar to what you are reporting. The dots look like they live below the clear. Were you able to polish them out? Thanks for any advise you can offer.

 

Congrats on your car, mine is a 2021 Red Mist also. The problem looks like it lies below the clear, base and whatever epoxy coating the factory uses down to the substrate during tooling or installation. This would be an unnecessary fix for a problem most people cannot see. Body work would include matching the metallic content of the paint, this would be tough to blend with the opposing panels. Very important to maintain the cohesiveness of the paint job because it looks almost like a metallic / candy from the factory. Even if you could buff it out, factory clear is notoriously thin and you will cut it down to the base quickly without experience or a good DA sander...and you will be sorry. As its on many new Corvettes, my advice is to enjoy your almost perfect car and look past this minor imperfection.

 

I am less concerned with this problem than I am the regular wear and tear that I will produce by driving the car often. Scuff marks on rocker panels, door panels, etc. I suppose these are just plastic bits though and can be ordered/replaced.

 

Presuming that BGA shuts down, for among other reasons to allow its employees time to attend to home, family and personal matters in the wake of the tornados, I wonder if that respite might allow its non-tornado path contractors to attend to "problems" that the relentless pressure to deliver to BGA on time prevents. I'm thinking of Tremec, in Wixon, MI - maybe a one-month break in BGA production will allow it to:

(a) produce transmissions for all those C8s waiting at dealerships for a replacement; and /or

(b) dive into its design and/or production processes to identify why its transmissions are failing and make corrections mid-year for when BGA production resumes.

 

Bowling Green got slammed by these tornadoes. At a time like this who cares about a car?

 

Lifted from the Mega-Tornado thread:

Stop. Humans are fully capable of cognitive dissonance - holding two disparate thoughts simultaneously. That means one can feel terrible for the victims of tragedy while simultaneously contemplating how said tragedy affects them. This is a Corvette forum, obviously by definition people come here for information about - guess what - Corvettes. Anyone who doesn’t admit to thinking about how it affects them is lying, and that doesn’t make them callous, cold, evil, or indifferent to suffering.

 

I'm sorry. I'm not one of the humans who would look at the damage in Bowling Green to houses and wonder "how long will it be before they get back to building C8s so I can get my car?"

I am retired. I'm a Mason and serve as the Secretary of my Lodge. We hold fundraisers to help the needy in our community. I am also a Shriner and serve as the Treasurer of my club. We raise money to fully support the Shriners Hospitals for Children. Shriners Hospitals for Children is a network of 22 non-profit medical facilities across North America. Children with orthopedic conditions, burns, spinal cord injuries, and cleft lip and palate are eligible for care and receive all services in a family-centered environment, regardless of the patients' ability to pay.

Cognitive dissonance doesn't apply to me. Sorry.

 

I find it very hard to believe that the only thoughts you've had today, or the only thing you have done today is related to the horrific tragedy in Kentucky. What has happened in Kentucky is horrific, so please don't take this the wrong way. Many of us are retired and give back to our communities. It is a very sad and tragic day and my thoughts and prayers go out to all those affected by the tornado.

But at the same time, I can't not wonder what has happened to my car. You see mine was built nearly 6 weeks ago and was on QC hold for 5 weeks due to the wheel issue prior to being released this week. Since I am not picking up the car at the dealership, I paid in full 5 weeks ago and have already paid taxes and registered it in my name. However, I was told it hadn't shipped yet, left wondering what might have happened to it especially since I already own it. Then, about an hour ago I received a call from MacMulkin saying they got word from Jack Cooper that it has in fact shipped. However, when they tracked the truck it shows that it left the plant, headed north and then circled back and returned to the plant. Both MM and I are left scratching our heads as to why the truck returned to the plant.

In the end, I truly feel sorrow and pain for all those affected by the tornado and hope for the best for all involved and their families. It is a very sad story indeed. But at the same time, I can't not wonder what is going on with my car especially since I already own it. Had I not paid for it yet, I wouldn't care as much as I do.

 

The Shriners is a worthwhile organization and your service to others is inspirational.

On this most difficult of days in Kentucky, I note that you are taking the time to read, and post in, a Forum dedicated to Corvettes, and specifically, a thread about Corvette problems that has nothing whatsoever to do with the disaster unfolding in Western Kentucky. With due respect to your laudable public service, please spare us your judgment, we who acknowledge that we are humans who can hold different thoughts and emotions simultaneously. And you might broaden your perspective to understand that BGA is an economic engine that feeds its employees, its vendors and their employees, and countless other businesses supporting the above. Wondering about when and how BGA gets back on its feet is part and parcel of worry for the entire community. Judge not lest ye be judged.

 

That wasn't the only thing I did yesterday. As I posted I'm the Treasurer for my Shrine Club and the night before we held a fundraiser for the hospitals that netted over $20k. I get pretty busy after nights like that but I do check my email.

I too wonder why Jack Cooper can't get your car to you. If it was loaded on one of their carriers maybe the weather was the cause of the driver turning around. I have no problem with people whose cars have been built and are sitting on trailers wondering about where there car is and when - not why - it will get on the road. Maybe by the time you read my reply you will know the answer to that question and can update us.

I didn't judge you. I said that using cognitive dissonance in a situation as horrible as what happened in Bowling Green would not apply to me and I posted why. If it applies to you and you don't have a problem with it that's your prerogative. I don't have to answer for you and vice-versa. You did judge me however by suggesting that I "broaden my perspective." Read post #179 in this thread and let me know if my perspective passes as good enough for you: https://www.corvetteforum.com/forums...tornado-9.html

 

Sure does. You've got your head on straight in my book. Carry on and God bless.

 

Thank you!

 

All you have to do is take a look at the reliability tables in the annual auto issue of Consumer Reports. Compare all the American auto company vehicles and then all the Toyota vehicles. You'll quickly note that there is no comparison.
Are Toyotas double the cost of comparable in size/features American a vehicles? No, not at all so you really can't justify poor quality because of cost. The most reliable vehicles by German manufacturers is Porsche. They placed 9th. BMW is in 12th place.
Have you ever wondered why GM had to recall all of their Bolts? They are finding that some of the battery packs are catching on fire. GM did not make the batteries but perhaps they rushed the Bolts out to customers clammering for electric cars.
Mazda and Toyota (1st and 2nd place) make good, inexpensive, and highly reliable vehicles. GM needs to learn a thing or two when it comes to quality.

 

Dave, these are unassailable points, well articulated. But what is your point? That Toyotas are more reliable? Given - no contest. Yet you have nearly 20,000 posts over many many years on this Corvette forum. Something must have drawn you to overlook the well-articulated shortfalls of the brand. Why are you still a Corvette guy? I'm not attacking you, I promise. Something Chevrolet or GM has done has made you a Corvette guy, and presumably something they are doing today is keeping you a Corvette guy. What is that thing that helps you overlook the quality gap?
