not really looking to know a fix as I know I will have to bring it into the dealership. Just wondering if anybody has ever ran into the same problem or heard of this issue?

So I'm driving home from work. Got the radio playing the iPod. All of a sudden radio turns off... hrrr? okay...? Hit the radio power button, nothing. About a minute later, still driving down the road, suddenly my gauge cluster resets. Now everything is at zero/turned off point. So I'm going down the road with everything off.

Now I get "services TPMS system", "service Airbag system", "service Traction control" and about 3-4 others on the cluster, but nothing else. GREAT!

I'm about 20 miles from home. So I pull into a parking lot. As I turn in. I notice my turn signal on my passenger rear view mirror isn't working. AWESOME. I hope my brake lights are working...
K turn in without getting rear ended or anything.

Turn off engine. Locks didn't open when I hit park(like they always do), gauge cluster still kept the backlighting on.

Tried the power locks to unlock. Nope nothing. Tried mirror controls, no response.
I pop the hood and disconnect the negative. Let it sit for a min, reconnect. truck fires right up and everything seem to be back to normal.

Continue back on the road. About 10 miles later, same thing happens again. I took the backway home, so I'm on empty roads alone. So I just figure I drive this all the way home. So gauges go out again along with the radio. So I said fuck it I'll get this thing home. About 5 minutes later they all come back on & its back to normal.

Then all of a sudden I got this voice "Thanks for calling onstar, this is Jennifer, how can I help you?"
"uhh... wtf"
:rofl2:
I didn't even call onstar.
I had her ran a "diagnostic" anyways, which I knew would come back "okay" and it did.
So I got it parked at home okay. Gotta call dealership tomorrow. oh fun.

This isn't the first time this has happened btw(first time was just sitting in my garage). I disconnected the battery and it worked fine. This was like.. 5 months ago?

So... anybody ever ran into this before?
:suicide:

I just had something similar to this in my 03 Trailblazer. Rolling down the highway at 65 with the cruise control set, press the window switch and no more cruise control. Repeated this 3x to confirm. Then all of the gauges froze at random intervals. It got fun twice when it just shut down, but was able to restart with no problem. Trouble turned out to be that I had a battery cell going bad. Replaced the battery, no more problems.

I guess my battery is good? Truck starts up no problem. No indication of this problem until it hit. I could swap batteries to see if it comes back, but with the problem so few and far between, who knows if that fixes it.

I left the battery unhooked over night(just to clean out the system) and I drove it around & no problems. I called the dealership(two actually) to see if its even worth while bringing in the truck. It was running okay. I just drove it to work and no problems.
They said it would be hard to diagnose if its working okay(which I can understand). So they suggest next time it fucks up to not touch it and get it towed.

:blah:

I'd say you have an 09, your battery is probably good. But GM trucks do crazy things like that when the batteries are going out.

My dad has an 09 CC and he had to have the battery replaced under warranty, but he didnt have the same problem you had. they left for vacation for a week and when they got home went to start the truck and nothing, the battery ended up having some bad cells.

Mine did this early last year. My girlfriend went outside to start it and came back in telling me it wasn't working right even though it was running. I thought she did something at first but she swore she didn't. After it stayed parked for about 30mins I got back in it and everything was fine. Hadn't happened since either. Never could figure out what it might have been.

Just to clarify about the "not starting".
I would turn over the key, the dash would light up, but nothing would happen. Like the starter was getting no juice or something. Not like it was TRYING to turn over and couldn't. It would be like trying to turn over the engine without a battery. Just silence and nothing.

Sounds like everybody is leaning towards battery issues. Maybe I should swap it anyways.

I'm not so sure about the battery problem. Truthfully I experienced something similar in my 07 when i first installed my original iPod interface with the factory radio. My dash went blank, no lights, mirrors, ect... Anyway it was diagnosed by my local shop, had them pull that interface and replace it with my current one, no problem since. So, not sure about what you have added to your truck, but if this is a new radio with an on-star replacement interface, or a factory radio ipod interface it may be worth the phone call. Check with the dealership, many times if they find the fault in the aftermarket goods, they will make you responsible for the diagnossis and repairs (removal of the aftermarket goods).

Hmm that is a good point. I do have an ipod adapter on there. I've had it on there since the beginning.

Nothing has happened since I posted *knock on wood*

Hmm thanks for the info though.

From my reading i found that to be a problem with a few brands of iPod interfaces for these trucks. I tried a couple till I found one from soundgate that works really well, still tough to navigate the iPod on my non-nav radio, but the truck works now. I also have a few other devices i use also, one for ZUNE, the simple plug and play iPod part from soundgate also and they all work well, no problems have popped up that I can see.

I never had anything that bad, but my truck was completely dead after sitting overnight on two occasions. I never knew what caused it, but I had to jump start it from my red truck each time. Kind of funny that a 10 year old truck was helping to get a new, low mileage truck up and going.

Bump!

My 08 half ton is doing something weird right now

When I'm cruising and hit the blinker or break pedal it kills half the speakers then they come back. Or it kills the aftermarket radio (installed for a few years without issues) and then it reboots and comes back on with music playing

The other day it lit up the red air bag logo on the dash and made the temp and direction deal on the rear view mirror show some alien words :rof

And now while cruising (and not doing anything) the doors locks would cycle

I disconnected the battery and parked it last night so I will try driving it tonight and see what happens...

I mean, it can't cause my breaks to lock up..... Can it!?

I could handle it dying, but screeching to a stop would be nuts!!

Very good possibility you're gonna need a new BCM.
