Local dealer just ordered a replacement radio for my new C7! Every 3 minutes the system shuts down and reboots. Steering wheel controls completely quit working. Dealer called corvette hotline and Chevy told the dealer to not work on the car. Chevy said they would send new radio out right away. Has anyone experienced this?? Has not over shadowed my infatuation with my new car... Just let's me hear those amazing exhaust notes even better!!

The radio not working is a known issue. Mines at the dealer as I type getting a replacement. Not sure about the steering controls, though. The engine in this car could catch on fire, nearly killing me and I'd still love it haha

JC; Let's not dismiss this radio bug as only a "known" issue. It should not be a topic of conversation on this, GM's flagship.

Are you being facetious ? I actually can't tell...

I actually had to have my infotainment screen replaced but since then it has worked great. I dont know if thats the radio issue folks are talking about.

 

[Chip]

JC; Not at all. A lot of times issues get short shrift because they are "known" about. They should not be there in the first place.

 

[JCobalt]

I was just informed by the service dept that it could be a loose connection on the harness, which means, in the future, the techs will have to check that before they just swap out the radio.

 

[Chip]

Will they have to pull the dash apart?

Ok I see what you're saying, my apologies.

 

[Chip]

None needed, good luck with yours!

I didn't ask, but the service advisor told me that Chevrolet said to check the wiring before the do a full replacement. I guess dealers were just changing them out without knowing the exact cause.

So I started this thread and I will follow up.... I traveled to California for 5 days. When I returned home I hopped in my C7 to head to work. To my surprise the battery was dead. 5 days of sitting killed the battery???? So.... I plugged in my charger for about 12 hours. The car fired with no problems and then guess what, all of my infotainment problems were fixed. My system no longer resets every 3 minutes, all of my steering wheel controls are now working, and there is no more popping noise while in Bluetooth mode!! Weird.... I called my local dealer (who still has no allocation for a C7 and yet can't believe I bought one else where ) and told them it was working fine now and I do not want them tearing into my dash to fix something that seemed to fix itself with a dead battery. Strange things but happy it is working!

Did killing your battery fix your problem and keep it fixed..? I have almost the same problem but the dealer is telling me not to take out my battery.. they have my car and I am not happy..
So after almost 10 days disconnecting the battery by the dealer cleared this problem.. This should be only used as a workaround and the Root Cause needs to be looked into by GM. It should be used to relieve the pain of Stingray customers.. Drove 200 miles this weekend no problems and they have said that GM will have future Software for this problems.

We have seen that the simple act of disconnecting one lead from the battery will sometimes clear up a lot of the infotainment problems on a short term basis, but GM is working on a (hopefully) permanent fix. Keep us posted!

We all know that the cars today are pretty much computers with an engine and wheels. Essentially what you have done is rebooted your system by having a dead battery and recharging it. Also I've seen where weak batteries can cause computer issues. Computer chips need voltages within certain specs, i.e. most microchips have 5v DC running to them, if this voltage gets too low they can act up.

disconnecting one lead will not always clear the car as the capacitors still hold electricity that can continue the fault. Leave it disconnected over night and yeah, probably....but GM techs use a "global reset" on the cars which is pretty standard in the industry for a quick reset. To CTRL-ALT-DEL the car, you disconnect both batt cables and touch them together for 10 secs, wait 10-30 sec and connect them back one at a time. Also, as said above, any bat voltage below about 12.1 (or erratic voltage) can lead to "phantom faults", like many have found when they get the "service rear axle" fault, and found it was a loose neg batt cable...

all this can be corroborated by asking a GM tech.... (verified with a master tech I know)

I won't ever know if the problems with mine loose cable since they are replacing the unit. With mine the info screen would flash another image on the screen and the steering wheel buttons would go dead.

 

[Rkindred]

Mine has been working fine I drove to Dallas checked into a hotel. Got up the next morning and the screen is completely black. Nothing tried restarting the car and nothing

No screen issues here but speaker in passenger side Door shutting off and on. Also making really loud popping noise. Gonna take it to dealer next week. Anybody else having this problem?
