Hello my name is Richard I own a 2014 Stingray.
I am new to this forum but, wanted to let everyone know about an issue my 2014 Stingray had and was repaired.
I picked up my Z51 automatic ...back in September, my car is one of the first 700 cars delivered.
Everything was fine for the first 480 miles but then, I started to notice a rattling noise when I was idling.
The noise was loud enough I could hear it with the top in and widows up.
I took the car in to my local dealer and after a few hours I was told although they could hear the noise...nothing was loose.
I was then told there just have not been enough Stingray deliveries to know if the problem was normal or not normal or if anything could be done to solve the issue..
I contacted Chevrolet customer assistance and explained my problem, Chevrolet was very interested and quickly move me up the channels.
I was contacted by the Service manager who let me know an engineer from the Corvette plant would be coming to Florida to listen to my car.
I asked the service manager if he could forward a short video to the engineer so he could listen to the problem before he arrived.
Below is a copy of my video.

Then I received another call from the service manager as a part had been sent from the plant .....would I come in?

when I arrived he walked me over to the garage to show me the part....to my surprise it was about 6 feet long and 2 feet around.
He told me the part was a Driveline support torque tube.
I am not technician so, to put in simple terms this part contains the driveshaft wrapped in a tube sorry I can not be more specific then that.
Feel free to do you own research.
I did not want to post anything until after the repair which is now done.... (two days) and many thousands in warranty repair costs but the noise is gone.....
at least for now. Since this issue did not happen right away I will have to wait and see.
I hope this helps someone who it hearing a rattling noise that was not there before ...you are not crazy GM may have an issue.
I would be glad to provide repairs orders,(as well as names of people with-in the service department that can be called) to the administrator of this site as proof this is a genuine issue.

Do you have headers.......if so they are warming up

 

Thank you for sharing this info and the video. They will be helpful to many. Hopefully your car is trouble free from now on.

 

Z51 7spd
Well a month ago I got a service rear end message pop up on the dash. I took it to the dealer & found out npt the low oil level problem but differential isn't locking.
They called GM & was told to replace the differential computer & the hydraulic pump. After that it worked fine for the last month but I just got the message again. I will be calling the dealer tomorrow & keep you guys informed.

 

Man...Sorry to hear this! Were they able to tell you anything about the failure mode for the first e-diff, like mechanical failure or ECU issues? Good luck and keep us posted, please add an entry into the E-Diff thread.

They thinking electronic but replaced pump too just in case. But threw code again so weird. Car still drives fine just might be spinning one tire more then it should.

 

I am also new to the forum and my name is Gerry
I was asked to re post this to get in the correct Thread.
Picked up my LT2 convertible C7 Dec 30. Drove it about a hour and lost voice control button on steering wheel blue tooth to my phone makes a loud clicking noise and drops my cell call... Navigation voice makes a loud clicking noise also when giving turn commands.. XM/FM radio stops working and seems to reboot about every 10 min. Random reboots to corvette screen. Sometimes the clock time changes back to 12:XX and then goes back to the correct time Dealer told me to remove all HD radio stations and try... turn off HD setting It made no changes ... They said Chevrolet says its a software problem.. And they are looking for a fix ... No resolution date provided... So my troubleshooting past tells me this could be a combo hardware software problem and they have been messing with it for the past 3 months... I will be on the phone Monday calling GM and expecting some one to give me something other than it's a software problem. I will try to update with anything I get back from Chevrolet.

01/08/14
Update I have been on the phone with GM support and they say that they are still working on the problem .. They did get back to me this morning and they have a software download that might improve my problems and I will take my C7 in tomorrow and they will download it for me.. I am not happy with the Chevrolet and how they are handling this. They say it is software and will not replace my nav system..
I say if it's software provide me with a fix.. or start troubleshooting the problem.. I still think that this could be a hardware issue and they don't care to come out with it now.. I say if you have a H/W problem
admit to it and get on with a fix.

I would like to suggest the the factory look into this problem in the diagnostic testing that they run after the car is built.. might be the RC but that's only a WAG on my part. BTW the battery reset corrected my problems after factory support requested Dealer do this.. they also updated with new software after 2 weeks. That's not to say that this is the total fix for the problem and root cause needs to be found but this is a Workaround. I will have to see how long it lasts but 505moters reports his power reset only corrected his problems since early November.

 

Good luck gsafre. Hope your problem gets fixed quickly and finally.

 

Thanks Gerry!

 

Does anyone know how the infotainment software update works? Does GM push update thru on star or we have to manually download updates and how do we know when they are available?

From my understanding, the dealership needs to flash the rom.

 

At this point it is dealer only. I have read where a dealers service dept. told an owner that it may take up to two hours to do. I wish I understood why it would take this long to accomplish?

edit: It seems that the 2 hr. figure was because the dealer had issues with the download. It appears it should only take a 1/2 hour or so depending on the individual who is doing the re-flash.

 

I took Scarlet in for an update a couple of weeks ago. Not sure if she needed a refresh or not. The process did take a while and I was told that the update must be initiated and completed serially, module by module. My originally delivered software (VIN in low 4000s) must have been ok since I didn't see any changes following the update. The software (or processor or both) remains rather slow...changing radio stations, media sources, driving mode changes, etc. Not a big deal, I guess.

 

Jan 7. New to the site and first post. I have about 2000 miles on my C7 and a few problems.
1- Oil leak at the reverse light switch on manual tranny. Switch replaced.
2- Right steering wheel control inoperative intermittently and no blue tooth connection: Bulletin #PIC5948. I am told software is being created but not yet available. The bulletin didn't say anything about the following, my emergency brake also released when I started the car during this problem. So it may be connected? Everything is working correctly at present, but keep it in gear when parked.
3- Instrument panel brightness too low. Chevy has a fix for this, but I haven’t gone back yet for the software update.

Two questions....are there Technical Service Bulletins or recalls on the C7's? Do dealers normally contact owners if there is a Technical Service Bulleting, such as the low differential fluid issue? Thanks,

 

Check the My Chevrolet web site If there are any recalls or bulletins for your car, thee should be there.

 

No recalls yet. Some owners are reporting that their dealers contacted them about TSB's, but many find out about them on forums such as ours first. We try to establish the correct TSB numbers and if owners contact their dealers service dept. they specifically ask about a given TSB. Your VIN will enable your service rep. to check to see if your car is included in any TSB's.

Has anyone had any issues with the back up camera getting blurry? Mine seems to blur anytime I back up into my driveway and/or garage. My husband thinks it may have an autofocus that is getting fixed on the pavement lines or something. If we stop and let it sit there for a minute the picture will clear up but as soon as we start moving again, it blurs.

 

I can't imagine an autofocus feature being part of the camera since it's always pointed at the same angle and fixed point. I'm wondering if the backup lights may be "blinding" to camera, especially if your driveway/garage floor are coated with a light color and/or reflective surface. I know that may be reaching. My driveway is surfaced in very light blue. I will attempt to replicate your problem tonight. BTW, this only happens in your driveway/garage?

 

Any change you're getting exhaust condensation onto the camera?

 

Doesn't the focus have to change? What about when you are backing into a garage/parking spot, and get closer and closer to a wall? Does it get blurry, or refocus? I wish I could experiment, but I don't have mine yet.

 

Tzmama, have your husband stand outside your car while you sit in it waiting for the camera image to clear up. After it is clear, don't move your car. Just sit there, but have your husband approach the car from the rear holding a big poster board or something large enough for the camera to have something with a varying distance to focus on. In that test, did the camera blur again or not? In this way, you can see if the car itself moving is causing the blurring, or if the relative motion between your car and the "wall" is causing the blurring.

If it blurs when your husband approaches with his fake "wall", then you know it is likely a focus issue with the camera. At that point, the dealer can probably help you.

If it does not blur in the test above, turn off all the electricity in your house (if you can do that safely and not cause a big headache). Then try to move your car as described in your first post and see if it still blurs. If it does not blur with all the electricity in your house off, you will surely not like the answer.

Good luck!

 

I tried to replicate the problem without success. Strong possibility I could have been wrong and there is an auto-focus capability. That would certainly make sense. If things don't improve, and the suggestion in the previous post doesn't yield any positive results, you might as well ask the dealer to take a look. Frankly, the quality of the image on my screen isn't as good as my 07 Nissan but I do get enough resolution to make it effective. Good luck. I look forward to hearing how the issue is resolved.

 

Thanks guys. I'll try that when my husband gets back in town. I'll let you know how it works out.

 

Haven't had a chance to try what was suggested but wanted to update. We have had some warmer days and I haven't noticed the issue happening. Makes me think that the person who told me it was the fog from the cold air hitting the exhaust possibly causing this issue is probably correct.

Chip, I am confused. I had mentioned two problems, the infotainment and a/c and it seemed you implied flashing would take care of both problems. Yes/No? My a/c cannot make up it's mind whether to cool me or do nothing!

 

I noticed the same thing. The auto climate feature does not really seem to work well. When I drove the car home from the dealership last week in the rain, the windows continually fogged up when the climate control was set on auto. The system would cycle the a/c on and off. Taking it off auto solved the problem.

 

I'm now officially in the screen flicker club. 1500 miles VIN less than 2000. Waiting til feb to see if it's a software glitch or new screen to fix

must be the day for bugs. I have the m7 and had my seat set to auto return to preset when you get back into the car which worked fine, I switched it back to manual so I could hold down the 1 button to pull my seat forward, worked fine the last two days and today when I hold down the button my steering wheel clips down a notch and nothing else, guess I'll go back to auto until some of these software bugs are fixed.

Kinda same thing with passenger side mirror, when I had it enabled for reverse to drop down worked fine for a bit, then stayed down so I had to disable the feature when backing up.....ah to be a beta tester....Love my vette though.

Anyone else and having the screen flicker problem could post their battery voltage when having the flickering. I don't know if this has anything to do with it but two times my screen is gone crazy my battery was at 13.9 or 14 and most the time it's at 15 or 15.1
