I have a 2017 Silverado that started displaying  "Steering Assist is reduced Drive with care" and "Service Stabilitrak" in February shortly after the vehicle rolled over 60,000 KM.  I brought it to the the dealer and the first two visits were covered under warranty, but did not resolve the issue.  Went back two more times and spent approximately $1000 and the issue went away for a couple of weeks and the issue returned.  I have also had a case open with GM regarding this issue as it appears to be a common problem based on the numerous web searches i have done.  I would recommend anyone with this issue to put a call into GM and complain.  I would also be interested in hearing if anyone had this issue and made it go away.

Welcome to the site.

 

Can you give more details on what was attempted to be fixed, what repairs were done?

I will post what was done in the next day or so once i find the details.  I did recently buy a bluedriver code reader and the codes that were pulled are as follows:

 

Power Steering Control Module Codes

U0428 CURRENT/HISTORY/MIL
Invalid Data Received From Steering Angle Sensor Module


U0415 CURRENT/HISTORY
Invalid Data Received From Anti-Lock Brake System (ABS) Control Module


U0126 CURRENT/HISTORY/MIL
Lost Communication With Steering Angle Sensor Module


C0544 CURRENT/HISTORY/MIL
Brake Pressure Sensor "B" Circuit/Open

 

Anti-Lock Brake System Codes

U0077 HISTORY
Control Module Communication Bus "E" Off


U0126 CURRENT/HISTORY/MIL
Lost Communication With Steering Angle Sensor Module


U0428 HISTORY
Invalid Data Received From Steering Angle Sensor Module

 

U0151 CURRENT/HISTORY/MIL
Lost Communication With Restraints Control Module


U0452 HISTORY
Invalid Data Received From Restraints Control Module

 

Human-Machine Interface Module Code

B127E HISTORY
No description available

 

I do know a sensor was replaced, there was a loose wire and they replaced a wiring harness.  After the wiring harness was replaced, it worked great for a couple of weeks and they started acting up again.  This issue was first reported when i was 500 KM past the warranty.  I shall post more details once i find them

Any updates? Did this ever get solved?

I am happy to report that it has been resolved.  In the end it was a series of loos wires between two junction boxes.  Details of what was done are in the attached photos.   The first two visits were free and covered under warranty.  There were two visits to the dealer that were not reported...the first one they found nothing (which i had to pay for) and the other one they determined the problem was with the steering angle sensor at a cost of $2000+ to replace (diagnostic charge i had to pay for....did not pay proceed with this repair)  my wife was pissed and posted a negative review on the dealers facebook page which prompted a call from the general manager, followed up with a call by the service manager.  this resulted in the final visit which was covered by the dealer.  the steering sensor was not replaced, but instead the work listed in the picture label "gm final fix.jpg"  I have sense put about 2000 km on this vehicle on highways, back country roads, rough roads and the sensor has not come back on.  I had also opened a case with GM with the issue as well, which is not tottally resolved yet.  will post more on that when i have more info.

My 2016 GMC 1500 SLE has been in the shop 4 times now due to Stabilizer issues, lost of steering, etc.  They replaced all the cables and some box that sits up top of the battery.  All cables to the steering gear and some control module last time for not communicating.  Now it's back in the shop as of last Tuesday for not starting, lost of steering, etc.and I won't be getting it until this coming Monday.  This is an ongoing issue with all the vehicles that share the 1/2 ton chassis, Chevy and GMC. (2014--2018) Yup, I also have an ongoing claim with GMC as it being an unsafe vehicle.  Twice I have narrowly missed other vehicles when the steering goes south.  

 

What gets me is we, the consumer , has to pay thru the nose to have these issues fixed.  I myself put the truck up on my lift and went thru several of the service bulletins.  But my GOD, these trucks today have more sensors than NASA does on the Space Shuttle!  I have actually talked with several salesmen that actually traded their vehicles in and "Let someone else pay for the repairs!"  Not encouraging is it?  But we will see what happens on Monday next!

Hi I’m curious what was done and if your truck is fixed? I’ve had mine into the dealer now three times and they can’t tell me what is wrong with it.

    • So after reading the reveal from Chevrolet, I kept asking myself...why did the trim levels change?   Here are the official ones:   Work Truck (WT): The quintessential fleet truck, built with durable, easy-to-clean interiors for commercial or utilitarian use. Custom: A stylish, road-oriented trim that adds a more refined appearance, standard dual exhaust, and modern exterior styling. Custom Trail Boss: An entry-level off-roader featuring a 2-inch factory suspension lift and 34-inch mud-terrain tires on a budget. Silverado: Serving as the new base consumer truck (replacing the previous LT trim), it comes standard with the Z71 off-road package when equipped with 4WD. Trail Boss: Steps up the off-road hardware with the 2-inch lift, 34-inch tires, monotube shocks, an exclusive off-road hood, and more premium interior options. ZR2: The flagship off-roader. It boasts 35-inch mud-terrain tires, Multimatic DSSV dampers, front and rear electronic lockers, forged carbon-fiber interior accents, and an available hardcore Bison Edition (co-developed with AEV). High Country: The pinnacle of luxury. It replaces bright chrome with modern satin chrome, 22-inch wheels, premium leather, real wood interior trim, a panoramic sunroof, and an exclusive front-passenger touchscreen. As others have stated, why would you want a Silverado - 'Silverado' - wth?? LT needs to remain!!!   Also, there will no longer be a dedicated Z71 model.  All 4x4 trucks will have the Z71 package. Carplay is also something that cannot be removed.  Hopefully it will remain.     I am excited about the 5.7L V8 (350 C.I.D.)  Old school Chevy power.  My only concern is whatever version of AFM/DFM cylinder deactivation.  Too bad that isn't an option a buyer can choose to have or not.   I will definitely be stopping by my local dealership when these trucks start showing up.
    • I haven't seen diesel for less than $5.30 anywhere in my area
    • The not as clean as one would assume theme with the new engine oil, that reminds me of comments over the years with mechanics not always being so on board with filling an oil filter, not from the center anyway due to that typically being the clean side of the filter, danger of some contaminant falling into the filter if not careful but the realization now that the oil may not be as pure as one had assumed it would surely be. Yes it would be possible to fill from the small holes but that means messing with something to prop open the anti drain back valve if the filter is so equipped and not damage that valve in the process. Me, I have hardly ever prefilled an engine oil filter however I have prefilled diesel fuel filters with a filter on a fuel bulk tank and for anyone that has messed with diesel engines with filters and units that have a limited or no way of priming them, putting on a dry filter is a bad day to say the least with those crappy systems. But anyway back to not so clean engine oil, indeed perhaps its not so bad after all that I have not made a practice of prefilling oil filters.    As Grumpy Bear commented on keeping things clean, that I really have to wonder what the typical practice is at a dealer or any other shop that changes engine oil, do they make sure to wipe or wash off the oil plug and certainly if it fell into some gunk or onto a dirty floor, or that they wiped the filter mounting flange and didn't go and use some dirty rag and end up adding dirt to the inside of the head of the filter mount. Or be careless in how they stored or handled the new filter and if they were bumping into items under the vehicle with the filter opening facing up and having dirt drop right into the filter and if so right into the threaded center that is on the clean side. The top side, did they clean away the built up gunk that may be around the filler before removing the cap or to be really careful at that point that something right close to the filler hole that was hidden under the caps flange won't fall into the engine. Or did they clean the funnel or was that just laying there covered in oil from the oil change before and dust kicked up from sweeping the floor stuck to the oil and now that will go running into the next persons engine due to just not cleaning the funnel as "they won't know anyway" attitude as that young guy is more worried about taking a break so he can go outside and smoke a joint. Just random points that came to mind when I think about what some hired personnel may do that the shop foreman has no idea of or perhaps the whole attitude of some shops may be "eh ... who cares, they will never know the difference anyway".  
    • $3.69 for 87 octane.   $4.24 for Diesel in town.
    • On the subject of OLM, Gm's OLM tool may be more "informed" than others brands. I recall OLM's in mid-2000's Chrysler products literally counting down a set number of miles. That's all the OLM appeared to be.    I would actually expect GM to be able to explain the parameters that their OLM takes into account from a high level. No, I would not expect them to disclose their software coding or data analysis around their parameters.   So we're talking about two different topics, so to continue the subject on the other one, I'd be curious to know how much "standard particulate matter" in fresh oil is able to be filtered at first start by a fresh oil filter. How much particulate matter is enough to "matter"?   I.e. how much of a "lever" do we think this equates to (variability in particulate content, in fresh oils, between different makes/brands, some which filter less, and some that filter more).   We can say that more particles = more wear = shorter engine life as a logical statement and use that data with a little marketing to scare people into selecting a more refined/filtered oil. Using a similie, is this like deciding to forego two alcoholic drinks in a lifetime because we're worried about the potential impact on lifespan? Are there numbers which translate the ISO test results into a quantifiable increase in wear for a given engine/use case?
