I have a ‘17 GMC 1500 Sierra Denali and I’ve recently started getting some error messages.  First, a couple weeks ago I got an error pop up on my info screen stating “Action Require - Open Then Close Driver Window”.  I rolled down the window and had to manually roll it back up by holding the button.  The one touch up wouldn’t work the first time.  The 2nd time I tried it worked ok.  Was ok for a few days but them came back later that week.

 

Then there was this past weekend.  Got the window error again, rolled window down like before.  Was in a long line at the dump with a load of yard trash to dump when suddenly I got a “Service Brake Assist” error come up on the dash.  Hit the dismiss and continued on my way.  However, every time the line inched forward the brakes were very touchy and grabby when coming to a slow stop. Got the truck emptied at the dump and proceeded to continue on with some errands. 

 

Once home I was checking emails & found two “Advanced Diagnostics” emails from OnStar.  The first stated that there was an “issue with the Antilock Braking System in your 2017 GMC Sierra”.  The second one was “an issue with the StabiliTrak stability control system”.  Both emails stated “Please service your vehicle within 7 days.”  

 

Just dropped off the vehicle at the dealership for them to check it out.  hopefully I’ll hear back from them in the morning.  

 

Anyone have similar issues all come up at the same time?  What was done to fix it?

Are you still on your original battery?

The open window message pops up for me when I leave the battery disconnected for a while. The other messages are similar to my experience in a suburban with a bad battery and corroded ground cable and grounding location. Replacing both, I never had the issue again. Good luck. Hope the dealer sorts it out.

actually yes, its still on its original battery.  Being the truck is only 2 1/2 years old, wouldn't have guessed that this could be a battery issue. 

 

Truck is at the dealership now and they're working on it.  When they call back I'll ask about that if they don't bring it up first.

Pretty sure they will say the battery is fine, I would replace it before the summer heat just to be safe.

 

Not sure why that is always the dealerships response, the batteries are almost $200.00 for these trucks, looks like they would want to sell more of them.

That was it...  dealership replaced the battery under warranty.

Good to hear, like having a new truck again.

Update...  Still getting the “Action Required - Open Then Close Driver Window” message at times.  Happens about once every other week or so.  Also noticed that the volt meter on the dash does not vary as much as it did in the past.  Almost always just a little above 14 on the gauge.  Once in a while it'll drop a tiny little bit below 14, but never down in the 13.0-ish range as it did in the past.  Anyone else experience this?

Any updates? Did this get fixed?

I occasionally see service stabilitrak after starting. Once in awhile get a service safety restraint system. 
 

3/36 warranty is up March 2021. Local GMC dealer just shut its doors...

    • Have considered installing a DC to DC charger in your camper to replace your isolator?  
    • Common failure.  You need to replace the fuel door housing.   The painted cover transfers over to the new housing.  To remove the old one there is 4 spots where you poke the plastic to release it.  
    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?
