I apologize for the problems you are experiencing with your vehicle. Please keep us posted on any information after you have visited the dealership.
Thank you,
Caron, GM Customer Service
Thank you for your response. I would definitely recommend taking the vehicle to the dealership even if only to have the vehicle diagnosed. Can you email me (SocialMedia@GM.com) your VIN, current mileage, concerns, and contact information? I look forward to hearing more from you.

For the past week. Every morning (below or near freezing point) when i start the SUV i will get the service vehicle soon and passkey flashing icons or other times the car interrior console and exterrior lights flicker. But throughout any of those symptoms i will still be able to run the vehicle normally (other then mentioned symptoms). The vehicle's motor behavior stays constant (knock on wood).
Sometimes the door locks will try to relock every second. If i unplug the negative current from battery (nothing changes with positive connector) wait for 30 seconds and replug it it will work fine all day. But the next day i'm back to square one.
Thank you for any help
Battery in tip top shape....SUV starts with no problem (starter turns fast)
(update) once the suv was heated up the problems stopped.
Here where the symptoms.
truck very warm interrior:
lights flicker
doors keep trying to relock over and over
passkey warning(once or twice)
0 and -2 degres celcius:
passkey warning
abs and awd warning
-2 and lower:
all of the above but never all at the same time
While searching the internet i came across i site explaining the problem with the earlier BCM's. That BCM'S for the rendezvous that had earlier version than GMAB410C had a faulty microprocessor that would give out when the ambiant tempertures would go to high or to low (hot summer day or cold winter).
In my truck i had version GMAB400D. So seeing as all my problems were connected to the bcm i ordered one off ebay(made sure it was a later version) cost 195$ with shipping and duties and 69.99 +tx to get it programmed from dealer.
This morning was a cold -9 ( -18 with chill factor ) and it started no problem with radio and all.
Btw. From my personnal experience if your radio is stock original and it locks the faulty bcm will keep locking it no matter what trick you do from the unplug battery.... pop fuse.... and even the unlocking of the radio ( right seek + 5 and then power)
Hope this can help someone save alot of $$$
