Hmm.. I read through the service history the poster has at a link on the forum
mentioned above and it seems that it is a bit "MORE" than just a rattle that
this person had with their Z06.

Doesn't seem so much that the car was messed up (granted there were alot of
problems with the car) but several dealers that provided substandard service on
the vehicle. It seems that they didn't know what they were doing when they
fixed the vehicle.

This is the service history they posted (seems pretty complete with Chevy
invoice numbers, etc)

2001 Millennium Yellow Corvette Z06 Service History AS OF JANUARY 9, 2002

they were obtained from GM suspension engineer Michael Neal and supplied to
Performance Chevrolet. The trim height adjustment was not performed correctly.
The technician had the front adjustment bolt all the way down on the front
passenger side and the front adjustment bolt all the way up on the front
drivers side. He was instructed that the bolts should be even. It took him
ALL DAY to accomplish this procedure that should have only taken 2 hours MAX.
He was instructed that the car needed to be realigned after the procedure. The
technician claims he did a NON COMPUTER alignment (WHICH I DID NOT REQUEST AS
STATED ON THE INVOICE) He did not align the car correctly and the steering
wheel was over 3 degrees off center to the left.

the other gears were still difficult to shift into including reverse.

They told me that the front end would have to be removed from the car to

complaint/ 5th dealer presented complaint)



I was told that they replaced the #2 compression ring and the oil expander ring
on all the pistons of my engine per GM Service bulletin 01-06-01-023.



I do not know if this repair was successful. I will be keeping a DETAILED log
of the oil consumption of my vehicle if any from the today’s date.



2. Transmission is difficult to shift, including reverse and pops out of
2nd gear sometimes. (4th complaint)



I was told that they vehicle was road tested and they indeed verified that my
vehicle was difficult to shift and popped out of gear. They removed the
transmission from the vehicle and found:



The 2nd gear synchronizer was damaged.

The snap ring on the 2nd gear assembly had failed.

The reverse gear synchronize was damaged.

There was a leak at the final drive unit.

There was a leak at the output shaft.



They replaced the 2nd and reverse gears and synchronizers along with the shift
fork and seals.



I was told that these problems were probably caused by SIR WALTER CHEVROLET’S
(RALEIGH, NC) failure to properly repair the transmission back in January 2001.



3. Slow drip LEAK of oil out of vehicle (Appears to be coming out of the
rear differential or transmission. (1st complaint)



I was told that they discovered that there were leaks at the final drive unit
and output shafts. The seals were replaced. I was told that this probably was
caused by SIR WALTER CHEVROLET’S (RALEIGH, NC) failure to properly repair the
transmission back in January 2001.



4. Suspension making clunking noises. (2nd complaint)



I was told that this was address while the transmission and differential
assemblies were removed from the vehicle. I was told that they cleaned and
inspected the mounting surfaces and fasteners for the REAR suspension members.



When I picked up the vehicle I went to the vehicle and pulled it up and
immediately heard a creaking and clunking noise in the suspension when I came
to a stop. I went back into the service department office and asked for the
Chris Kimball, Shop Foreman and explained to him the problem. He asked me to
go on a test drive with him so that he could hear the problem himself. We
drove around the parking lot of Performance Chevrolet and he heard the noise
and said “I didn’t hear that on my test drive.” He asked me to pull the
car back around to the service department. After waiting an additional 20
minutes, I was told that they had to re-torque the front suspension cradle
bolts as they were loose. Something was said to the effect that they probably
should have done that anyway after they 1st road tested the car.



I have not yet road tested the car sufficiently to determine if this problem
has been corrected. I will be driving the vehicle to determine whether or not
this problem has been fixed and will not reoccur.



I was told that the original problem was probably caused by SIR WALTER
CHEVROLET’S (RALEIGH, NC) failure to reassemble the suspension components
when the performed the transmission repair in January 2001.



5. PAINT AND BODY PANEL CRACKING ON REAR LEFT QUARTER PANEL. (1st
complaint)



I was told that my vehicle has a fracture within the body panel on the left
rear quarter panel. I was told that this would be repaired under warranty as
it was obvious that this fracture was not caused by anything hitting the
vehicle from the inside or outside and was apparently caused by the body panel
being DEFECTIVE.



THIS PROBLEM WAS NOT CORRECTED!!!



I was told several times during the repair of my vehicle and upon picking it up
that Performance COULD NOT complete this repair on my vehicle. When I picked
up my vehicle, I informed my service advisor, Scott Lewis, that GM still had 4
CALENDAR DAYS to complete this repair. I asked him where I was to take the
vehicle and who and when would they be completing the repair. He stated to me
that HE DIDN’T know.



I informed Mr. Lewis that I was prepared to take the vehicle wherever GM
directed me to take it for this repair to be completed. I told him that I
wanted to do this and wanted to be sure the GM had the opportunity to complete
this repair before the expiration of the 15 calendar day final repair attempt
period. He again stated that HE DIDN’T know.



6. Rear facia is warped on Passenger side. (1st complaint)



I was told that they compared my rear facia to other Corvettes on the
Performance Chevrolet lot. I was told that all the vehicles have comparable
rear facia variances. I was told that sagging in my rear facia was normal.
While I was waiting to pick my vehicle up, I looked at all the other Corvettes
on their lot and NOT ONE had a rear facia that was sagging and not symmetrical
on both sides. My rear facia sags and IS NOT symmetrical on both sides. I
offered this information to Performance staff was GIVEN NO EXPLANATION!!!



THIS PROBLEM WAS NOT CORRECTED!!!



I have photographs of other Corvettes with the same rear facia as well as my
2000 Corvette and that these vehicles DO NOT exhibit any warping or sagging
instead they are symmetrical on both sides. I also compared my rear facia to
all the other Corvettes on their lot and NOT ONE had a rear facia that was
sagging and not symmetrical on both sides. My rear facia sags and IS NOT
symmetrical on both sides Due to this, I do not feel that the sagging/warping
is NORMAL.

transmission repair that was performed by SIR WALTER CHEVROLET (RALEIGH, NC.)

the brake cables.

has been corrected. I will be driving the vehicle to determine whether or not
this problem has been fixed and will not reoccur.



8. Deck lid rattles. (2nd complaint)



I was told that the compartment separator attachments were loose and rattling.
They tightened the attachment points.



I have not yet road tested the car sufficiently to determine if this problem

9. Alternator makes squealing noise sometimes. (1st complaint)



This problem was intermittent as had not occurred for some time. They
attempted to duplicate this problem and were not able to. There has been no
reoccurrence of this problem.

I was told the rim was scratched by the (incorrect) installation of the wheel
weight by the FACTORY. The weight came off during a repair by Sir Walter
Chevrolet and a new one was installed by Sir Walter Chevrolet during a previous
service visit.



THIS PROBLEM WAS NOT CORRECTED!!!



I had shown this to Mr. Ricky Edwards, Service Manager at Sir Walter Chevrolet,
and that he told me that they would replace the affected rims under warranty



11. Mufflers rattling. (1st complaint)



I was told that they were unable to duplicate this problem. I informed them
that this problem was intermittent. They stated that this problem was probably
caused by SIR WALTER CHEVROLET’S failure to reassemble components during the
transmission repair in January 2001.



I was told that this problem was corrected during the reassembly of components
during the transmission repair performed on this visit.



At this time, it appears that this problem has been corrected.

This was replaced. I was told that this was done as a “GOODWILL GESTURE.”



13. Memory feature sometimes will not work. (1st complaint)

they inspected the memory system and power seat operation and no fault was
found.



THIS PROBLEM WAS NOT CORRECTED!!!

the key, the seat either does not move forward or instead moves backward
forcing itself into the rear gas tank wall



14. Excessive fuel consumption during highway cruising in 6th gear **16-18
mph average at 60 – 70mph**. (1st complaint)



I was told that they tested for this problem by driving the car approximately
14 miles and checking the instant average fuel consumption on the DIC. I was
told based off of this (INCORRECT) test, it was determined that there was NO
excessive fuel consumption.



Given the instant average on the DIC can vary from 1MPG to 70+ MPG within
seconds. THIS IS NOT THE GM PRESCRIBED MANNER TO TEST FOR EXCESSIVE FUEL
CONSUMPTION.



THIS PROBLEM WAS NOT CORRECTED!!!



15. Front console cover distorted and misaligned. (2nd complaint)



I was told that the console cover was warped. They replaced the item.



This problem has been corrected.



16. Brake rotors starting to warp. (1st complaint)



I was told that the rotors had excessive thickness variation that caused
pulsation when braking. The thickness variation has .005 on the left rotor and
..006 on the right rotor.



Both front rotors were RESURFACED.



It appears that at this time, the problem has been corrected. It has been
reported that a reoccurrence of this problem CAN happen after a REFUFACING
repair. I will be watching to see if this problem reoccurs.



17. Car has vibration at upper highway speeds. (1st complaint)



I was told that they found no vibration at 65-70mph. I was also told that the
alignment correction that was performed most likely would correct any problem
that I may have been experiencing.



18. Tires excessive uneven wear due to incorrect alignment. (1st complaint)



I was told that the tire wear was normal.



19. Alignment and steering wheel position not correct. (4th complaint)

Z06 Screen variances. I was told that defect in my Z06 Screen was normal.
While I was waiting to pick my vehicle up, I looked at all the other Z06
Corvettes on their lot and NOT ONE had a defective Z06 Screen like mine is. I
offered this information to Performance staff was GIVEN NO EXPLANATION!!!



THIS PROBLEM WAS NOT CORRECTED!!!



I have photographs of other Z06 Corvettes with the same screen and that these
vehicles DO NOT exhibit this defective condition. This defective condition was
brought to my attention by Donald Creech at Sir Walter Chevrolet and I in turn
brought it to the attention of Mr. Ricky Edwards, Service Manager at Sir
Walter Chevrolet. Mr. Edwards informed me that if I desired, he would have the
screen repaired/replaced under warranty and that it was a warranty issue.
Also, while I was waiting to pick my vehicle up, I looked at all the other Z06
Corvettes on the Performance Chevrolet lot and NOT ONE had a defective Z06
Screen like mine is. I offered this information to Performance staff was GIVEN
NO EXPLANATION!!!



Due to this, I do not feel that the defective condition of my screen is NORMAL.
