Default Rework, before shipment

Do all corvettes come off line ready to be shipped. What if they are not perfect. How do they get "fixed up" ??

I can tell you how it used to work, which I'm assuming still works this way.
Any problems discovered while going down the line are fixed on the line if possible. Once off the line, a couple of tests are run, such as the watertight test. Random vehicles are chosen for short road tests as well. The cars are then put on a two week quality hold at the plant before shipping. If any problems are discovered in assembly, this gives a two week inventory that can be "fixed" at the plant before shipping. Then the cars are sent out.
This is the way BG used to operate according to all of the plant tours and R8C's I've done with C6's. I would assume it's still this way.

A QC sheet follows each car down the line. Anything that is not fixed is noted on the sheet. At the end of the line, any cars with uncorrected items get pulled aside and go into the repair bays to get the problem fixed.

Not sure about the 2 week hold. They definitely do that for NCM deliveries, but my C6 was at my dealer 3 days after it was built. There have been some reports on the forum of people getting their C7's delivered less than 2 weeks after build (although certainly not those shipping by rail).

I think you're right that the two week hold is not part of the deal. Everyone is in a rush to get that new Stingray.

The best you can get is a Global Customer Audit where the car is flagged for detailed inspection after it rolls off the line.

I think the two week hold only applies to museum delivery cars.

Sorry, I don't know what a global customer audit is..I assume visual inspection is one thing, paint match, pane to panel, panel fit, etc.,) but is car put on lift and inspected ,running, for noises, is tranny run through its paces ? are a multitude of checks performed, is car ready to "fly"?? Is mileage ever put on the meter for testing, and if so is it removed befor shipment.?

if it's shipped by rail, than it gets a 4 week "hold" in some rail yard, somewhere.

At the end of the assembly line, the car goes through a lighted tunnel where they look for visual defects etc, then it is started. All the various functions are checked by a worker in the car(lights, wipers etc). They drive it across some rumble strips onto a chassis dyno where the running function are checked, then through a water spray . If the car fails, it is moved to a repair area. If it passes, it is moved outside. Some of the cars moved outside are selected for a more through driving test around a course at the plant. The amount of space inside for simple repairs is limited, so if there are a bunch of cars that need minor repairs, they are temporary moved outside.

If there is a serious mechanical problem that affects many cars, they are normally trucked to Jack Roush in Michigan for repairs and then returned to Bowling Green for delivery to the dealers.

There is a calibration process at the end of the line where the car is run through different speeds and loads while the computer, transmission, etc. are calibrated.

3 to 30 miles depending on the QC testing.and NO it is not removed!

Personally I'd rather have a few miles on mine from the factory and know the car was thoroughly checked out. The factory is a much better place to fix any minor issues than your local dealer..

Yes, a very small number of cars are selected for a QC/test drive. About 25-30 miles or so. Mileage is not "removed" before shipment. Rolling back mileage completely illegal.

Mine was built 3/13, then confirmed independently by CSX to have arrived and left the New Boston, MI rail yard on the 20th.

They have a few quality control checks along the way but not a lot. Everything depends what defect they find. Basically the line never stops moving. If any tech finds defect they can pull the help chain if they can't correct. That CAN stop the line but at least send help fast. They also have a place or two they can pull a car out of line to fix or study. Usually defects are fixed after though and really except the bright lights for paint and some electronic checks in a booth like sort of dyno , except 45mph, that check emissions etc. They do that just after the first start-up right after the car goes though the filling station there aren't lot of additional checks done by "other" people. They do all models at any time including mixed colors...like a rainbow of Vettes...



My memory is a few years old on the exact sequence but it most likely hasn't changed very much on assembly sequence. Its really amazing, a tiny little lady was installing ls3's and ls7's back to back and never sweated.

My car came off the line and went to 4D00 hold for some reason. Customer Care told me it was likely a last quality check. My guess is that it involved some kind of fix, or adjustment. The car was out of hold 2 days later so it must not have been a big deal. I ordered a stinger stripe and wondered if the hold might have been for that. I don't think they do striping on the line.

Stinger stripe held me up about a week. Chevy tracking lost all connection to the car for that week and the answers I kept getting upon inquiry were unbelievable.
