2015 Silverado Disappointing

[stan5050]

I am starting to get irritated with GM's quality control at least with my Silverado.  I have always bought GM as my father and wife's grandfather retired from GM.  Both my wife and I are Kettering University (old GM institute) alumni as well.  That being said, my truck is currently at the dealership because I shut it off while in the "auto" mode for 4WD which caused it to get stuck in 4WD mode.  Apparently, the fix for this is a $145 software update...  First of all, why does the truck allow you to shut it off while in auto mode and/or why does this cause an issue no one warns you about.  Second of all, if this is an issue, why is GM charging for a software update.  No other industry does this, if you choose to use more and more software in your vehicles then you should provide the needed updates.

I have never had a problem with turning the truck off and on in auto 4wd. I don't do it all the time but sometimes just forget. What does the update do? Does it not allow it to stay in auto when you turn truck off or what?

Interesting question.

A software doesn't wear out like a transmission or engine.

One does not need to change/update the software unless he wants to improve things.

But in your case it's not about improvement.

It is to fix the software because it was faulty in the first place.

Am I wrong?

i get where you are coming from, but any other manufacturer is going to charge for an update as well if you are out of warranty. How many miles are on the truck? this should be covered by the powertrain warranty.

[stan5050]

I have 61k miles on it so it’s still under powertrain warranty but the dealership said this isn’t covered by it. 

[stan5050]

I’m not exactly sure what the software update does yet as I haven’t picked up the truck yet but from what I’ve read there has been a couple TSB and even a recall (3yr/36k mile limit) for this issue. 

[j13smiley]

Yes, there are threads here about this issue and the fix. They should not be charging for it.

This isnt specifically auto 4wd or turning vehicle on or off because it was happening in any 4wd mode.

Recall 15304
4wd always engaged in cold temp
Expires with base warranty
Updated calibration
Transfer case shift control module reprogramming with SPS 9101695.

In low ambient temperatures, below 5°F (-15°C) a transfer case brake motor assembly malfunction may occur. Diagnostic Trouble Code (C0398 - Range Position Correlation Fault) will be set, locking the transfer case in “4HI” until the vehicle is serviced.

This is why I like this forum!  It felt/seemed like my truck was still in 4 auto yesterday after switching back to 2 wd.   Maybe I should get this checked!  When there has been continuous snow I leave my truck in 4 auto.  I often shut my truck off while still in 4 auto and didn't ever hear or read that this was wrong.  Is it?  My last Sierra ('09)  got me through 6 Canadian winters treating 4 auto in the same manner.

I agree with you 100%.

I think the answer is GREED or PROFIT.

Pick one or both.

I had the T-case software recall done in late 2014 or early '15 months after buying my truck new.  I leave my truck in Auto a lot when on the job site.  I do a lot of starting and stopping.  No issues ever with my Tcase.  I can tell night and day when my truck is in Auto Vs 2wd.   Never had an issue.  Sounds like the recall might have expired? Says it expires with base warranty which is the 3yr/36k IIRC.  Either way, call GM's CS # and see if they can help a brother out.
