I believe if it was a true issue with passkey system it would indeed not start (or if it did, it wouldn't stay running). If you have sunroof, any chance it was leaking and allowing mositure to go where it shouldn't?

everything is sealed tight. Today tempertures were a couple degres above and it started without any problems.
#19 of 26 still going
Oct 29, 2013 (5:23 am)
this morning... minus 5 celcius and vehicle is going crazy...no way of stopping other than unplugging battery. When i replug and start it i get....passkey warning...or...flickering lights...or...back door opened.
(update) once the suv was heated up the problems stopped.

In lieu of any other ideas (and if it seems to run ok for now) I have thought that may or may not work (still thing about possible mositure thing). In my Pontiac version there are two doors (one on each side of center console where shifter may be). You could remove these doors and run heater on full (blower on high) with heat directed towards floor for a couple days and see if it changes anything. Wouldn't cost you anything but warm toes

waited for another cold day for the problems to return. This morning it was minus 5 outside and truck flickered alot. So shut it down..went in the house and got my heat gun and heated up the area were the bcm and fusebox is located. No more flickering at all. Still have the radio problem. I can unlock it using "right seek" + 5 button + power button. But will relock about 10 seconds after playing radio and all.
#23 of 26 mecanic scan
Nov 11, 2013 (1:30 pm)
my mecanic put it on obd2 senson and gave a code in the bcm that he said can't be "P026C". He tested all wires that came back nice. So he suggest changing BCM. So i ordered new one on ebay and waiting to see if that is the problem.
#24 of 26 becoming frustrated with this tire issue
Nov 17, 2013 (5:07 am)
I bought my 02 about 5 years ago and I have had nothing but problems with the front driver's side tire. 4 days after purchasing I had it back to the dealer bc the sound I questioned during our test drive had not gone away after they serviced it before I took ownership. It sounds like a loud thunk when I make a right hand turn or drive over a man-hole cover and I fear the whole tire is going to fall off. I took my Rendezvous back to the dealer about once every 3-4 months during the first 3 years I owned it bc I purchased the best extended warranty that was offered - surprise that most items still were not covered. I have replaced the shocks and the compressor to the stabilizer 2x (once with the help of GM)- and now the car is scheduled to back into the shop this week for the same problem (which the Buick dealer told me is a known issue in this vehicle). Two days ago every light on my dashboard lit up and they have not turned off. The radio LOCKS about once a month -luckily I was able to locate the fuse to reset this issue (dealer wanted $85 just to look at it!). I have not had AC for 3 years and now the heat is working poorly as well (it takes 25 minutes on defrost to clear the slightest bit of frost) and my fuel gauge has stopped working. I love this car but the mechanical issues are getting to be ridiculous!

Try locating the fuse to the radio. In my Buick the fuse is in the panel on the passenger side and it is the next to last fuse on the right end of the lowest row. My dealer wanted to charge me $85 to even look at the vehicle the first time this happened about 3 years ago. My radio goes into LOCKED mode about once every month or two so paying the dealer price would have gotten expensive pretty quick. Hope this helps.
#26 of 26 ok here we go
Nov 28, 2013 (7:11 am)
ok so after over a month and a half of having the truck i finally fixed it.
Here where the symptoms.
truck very warm interrior:
doors keep trying to relock over and over
passkey warning(once or twice)
0 and -2 degres celcius:
abs and awd warning
-2 and lower:
all of the above but never all at the same time
While searching the internet i came across i site explaining the problem with the earlier BCM's. That BCM'S for the rendezvous that had earlier version than GMAB410C had a faulty microprocessor that would give out when the ambiant tempertures would go to high or to low (hot summer day or cold winter).
In my truck i had version GMAB400D. So seeing as all my problems were connected to the bcm i ordered one off ebay(made sure it was a later version) cost 195$ 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 $$$
