Service stabilitrak to electronic freakout

Has anyone had an issue similar to this?

 

I was driving up a mountain on my way back to Vegas from LA today. Halfway up the mountain I start getting random service stabilitrak messages. My power inverter starts popping in and out. I figure its a glitch and it'll resolve itself. As the messages kept disappearing a half-second later. Further on, the messages get a little more often and I got the power steering assist reduced message. From there, I decide to pull over when I find a safe turnout. Soon as i find one, I hit the emergencies and let the people pass me as the turnout is on the left. Make the left and then everything goes haywire. Truck starts flashing the screens and power is on and off. Doors unlocking and locking and basically everything is like jump starting left and right. One more thing, while driving up the mountain at 35-40 mph, the cruise control randomly turned itself on and set it to 73 mph. I turned it off and kept going. Reset the truck by turning it off and back on and it got me home the next 300 miles. I had the power steering message once before a month ago and just assumed it was a fluke as it seemed to resolve itself. I'm going to the dealer on Friday.

 

So, I'm just wondering if anyone has experience anything like this and how worried I should be.

Could be a bad battery or a bad ground. I would check the battery cables first, then have the battery tested.

Check your battery. There will be a date on it. Most batterys last 3 to 5 yrs. nin the new cars im gonna day 3 cause of all the electronics. Svc stabilitrack came on in my camaro after i got a mis cyl 2. These new cars are weird. Check your battery first.

This is a known issue!! Check out my post on page 4. I recently traded my truck in for a '16 so my headache is gone. They "fixed" the issue after 3 weeks of having my truck, replacing both battery cables (which the negative now gets grounded in a different spot) and replacing the entire fuse box.

Yeah I'll be taking it to the dealer soon. Makes me want to unload the truck because it locked the steering on me.

I had a similar occurrence. I had warnings from almost every system in the truck come up. Turned the truck off, some warnings came up again, truck was running fine. i started to drive and realized that none of my gauges were working, no speedo/tach, fuel etc, the radio worked though. Happened to be in town where the GM dealer is, parked it in the service bay and told my story. Started it up and everything worked. They looked at the stored codes and reprogrammed (bcm/pcm? some kind of cm module). Has worked since-30000km. Was a warranty issue with no fuss at all.

Dealer says my HIDs are "misinstalled" causing avoltage drop. Somehow the two wires one to ground and one to positive on the battery are doing that. I'll just put it back to stock and see what they say if it happens again.

Further update. The service advisor that said it was misinstalled said that it caused a voltage drop. However the printout from the service tech stated that they couldn't recreate it and all the grounds seem to be ok. Also they noted that the aftermarket ballasts have a possiblity for causing that and that everything seems to test fine. They unplugged my hids from the battery at any point.

    • This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.  
    • 2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.  
    • Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
