Stabilitrack Light and quick loss of power after hitting bump

About a month ago I was pulling into the hospital, my son was sick, we were looking for the ER entrance, going about 10 MPH and didn't notice 3 speed bumps all in a row, 12 inches apart. Hit them at around 10 and obviously it gave the truck a good shaking.  The truck turned off and the service stabilitrak light came on. I turned it back on and everything seemed fine.  I thought it was weird but was preoccupied.  (my son was/is fine)

 

anyway but to yesterday I had forgotten about this incident and was driving down the road and hit a few patched potholes, nothing major but it jarred the truck a little and for a split second I felt like I lost power steering and the service stabilitrack message came and went very quick.

 

Do I have a loose sensor somewhere?

 

Could this have to do with the EPS recall?

 

thanks,

I would take a look at your battery cables and make sure they are both tight and in good condition. I know the negative cable can cause problems like this.

My 2017 2500 had the Stabi message come up and the dash went dark while I was plowing and hit a bump with the plow this past weekend.

I have not. I went about a month with nothing happening, then I drove over a railroad track and had the message flash real quick and I think the steering got tight for a split second.  I need to get under there this weekend to see if a speed sensor is loose.   I also need to hit the dealer for the power steering software recall flash, not sure if that has anything to do with it.

So Sunday I found that the negative battery cable was loose. I tightened it and figured that was my problem. Car was fine yesterday, even when I hit the railroad tracks I cross on my commute, but when I drove over them today the same thing happened. split second loss of power, stabiltrack light, radio resets to 87.7 FM, all my presets disapear then 2 seconds later they all come back.

 

I am now wondering if it is a ground wire

Glad your son is okay...yeah sounds like a loose ground somewhere and you might even want to re-check the battery terminals again.

I know there is a problematic ground wire under the dash near the speaker on the drivers side, but is there a large ground wire somewhere in the engine compartment near the battery?  anyone know the exact location?

Emery, I'm having the same problem you had. Did you ever figure out what the issue was?

My 2015 Tahoe does this same thing over big bumps. I found this thread and he even included a GM Service advisory on the ground wire on the driver side dash, it's deep in the corner under the windshield. I did it yesterday myself and it wasn't a major issue. The insulation was exactly how they said it would look like. Dash went back on no problem as well. Here is the link with all the info you need and make sure this applies to your year/model vehicle. This guy did major homework and really provided all the info to get the job done.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      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.

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      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.

      Active Grille Delete

      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?
