Intellilink Malfunction

[Kerrville15]

While going on a trip a couple of weeks ago, my navigation stopped working, my bluetooth wouldn't work either so my phones wouldn't connect or anything, and my backup camera wouldn't come on. Don't know if this is related, but after stopping at a stop sign the Yukon kind of stuttered before it took off, and then after a little hesitation it took right off & was fine. I tried shutting the car off a couple of times thinking it would just reset everything with no luck. So after I got to my destination the car sat overnight and everything has been fine ever since. Anybody else had the issue or have any thoughts?

I have a three week old Tahoe--2015. The exact issues are showing up in my vehicle. On the first call to MyLink support I was told--
1. With the vehicle running, turn off the entire system by holding the radio volume button in until the clock shows on the screen.
2. Turn off the vehicle.
3. Get out and lock the doors.
4. Wait three minutes and reenter the vehicle.
5. Start it up.
6. Turn the system on using the radio volume button.
I explained that this happened at 65 MPH on I 35 and if it happened again I would be calling back.
I followed the procedure.
Everything worked.
The next day the exact thing happened. I called MyLink and basically gave it to them.
They called my dealer.
I am now awaiting a call from the dealer to bring it in for service.
Of note--the voice command system only works every so often. It loves to call random people in my phone book rather than the specific one I requested.

Update--

The dealer did a "hard reset".
The negative battery cable was disconnected and left off for about an hour.
Everything seems to be working.
Fingers are crossed----

failed--

Back to the dealer. The screen went black three times yesterday.

What was the resolution for your issue?

 

[BobMc]

It has continued to fail after software updates. No physical parts have been replaced or repaired. The vehicle was at the dealer's on 28 September and again on 30 September after multiple failures.
The dealer is now awaiting a software update from GM.
This is not making me happy as I have been advised to be ready to use my iPhone or bring a GPS for navigation support on my 4,000 mile trip starting on 6 October.

To date we have had the electronic com module and the rearview mirror assbly replaced. Too many updates to count. Awaiting a call from Onstar to our dealership regarding the unresolved issue. Two months of ownership, four trips to the dealership and one week out of service.
Edit: forgot one dealership trip.

 

[BobMc]

Nine weeks of ownership.
Five trips to a dealer.
Two days out of service.
