My truck is currently stuck in auto 4wd, dealership is to busy to get it in. Might be able to look at it as an emergency Monday am. I tried disconnecting the negative terminal, and didn't fix it. Strange part is none of my radio presets were erased after disconnecting negative terminal either, possibly didn't leave it disconnected long enough.

I have the same problem and just got done posting a long narrative about my ordeal under another topic heading. The long story short is I was told about the service bulletin and the same BS about have

Had similiar to this happen to me early this week. Drove about 80 miles in 4wd (tthrough the bad ice/snow storm Tennessee got). Next morning, truck idled rough, vibrated a little while driving. Mid afternoon took it out of 4wd and back to 2wd. Noticed it was still steering heavy and I could feel the front end still pulling a little and intermittently jerking.

 

Went to a big parking lot and back up, turning wheels left and right while backing up. No noticeable sound or feeling during but as soon as I drove forward I could tell I was definitely in 2wd now.

 

Never any messages in dash, no lights. But it was definitely still in 4wd even though truck dial indicated 2wd and I got the notification message about "switching 4wd mode" when I moved the dial from 4wd to 2wd.

Mine goes in tomorrow to reprogram but dealer hasn't heard of a fix! I mentioned PIP5220B but they haven't gotten any fix for cold temperatures causing 4 x 4 trouble except the same one which has to have the truck put back in 2 wd before shutdown!!!! Almost 3 months now!

same issue on 2015 canyon, goes back to clear codes tomorrow

I was wondering how long it would take for the Canyon and Colorado issues to start showing up. I was hoping GM would have been all over this for the new trucks, but I guess I shouldn't have got my hopes up.

Had my truck reprogrammed today and dealer said that they have been using PIP5220B and the trucks are still coming back with the same issues and codes! So much for a fix!

I dropped off mine today after it threw codes this weekend. Showed up unannounced abd left with a loaner. This is the fourth visit. The third visit they replaced a switch in/on the transfer case then discovered that the harness pins were not seated correctly.

Received a call last Thursday. A GM engineer called my local dealer(Chicago area) and said they are going to be mailing out a new part, I don't recall what the was called. Hope that this part works, stuck in 4hi currently.

Had mine at the dealer in Feb. for this. Cleared codes, and "we'll call when we have a fix"

 

I got called tuesday. Truck goes in friday. Tech says they are replacing the module. Won't know if it's really fixed untill next winter if it's the cold temps that make it screw up.

My part is somehow still on order. I have been leaving it in auto to see if it would happen again, but with warmer weather no issues.

      OCI, not when but why?

      By Atlas · Posted

      People mislead themselves. Statistics are highly useful indicators.   Here's the tie-in to this thread. If an oil sample tests shows a wear indicator of 7 using cheaper ACDelco oil, and a wear indicator of 2 (lower = less wear) using a particular brand of Mobil oil, and wear has a linear relationship with engine lifespan, anyone could assume that Mobil is reducing wear by more than 50% (let's just say a 200% reduction for you red state people trying hard to do math) which leads to increasing engine life by 2x. Perhaps, in a vacuum, by itself, when dreamed by AI.   Yeah?! That's what the statistic is saying, isn't it?   No, it isn't. It didn't come out and say engine life is doubled. That's a very bad assumption, and a case of severe myopia by assuming something potentially untrue about the only data point in focus.   Average cost of a new car is 50k. You bet it is.   The median cost of a new car is more like 35k. Expensive cars are skewing the perception that "average" now means a $50k price of entry for a very average automobile. And that's not true. People who don't understand statistics twist the living heck out of them to mean all sorts of things they don't actually mean.   "Average" new car payment is $1000/month. Yep, it is. And in that number are all the $35k new car buyers who bring significant equity, and the $25k new car buyers who finance the car for a month just to get a rebate, and then pay it off. Know what isn't in that number? All the payments made by people who don't finance a car.   Picking one's own data point (don't have a car payment, never paid $50k for a new vehicle, my house cost $170k, I afforded a middle class lifestyle on $4.50/hr) is just a data point. Just like earning $25/hr in an area where the median home price is almost $1 Million is a data point. In fact, it's a lot of data points given that 80% of the US population lives in/around major cities. They're not idiots; the vast majority of them do it to make a living because that's where the big money is.   The highs have become higher, lows have become lower, and how your personal mileage varies is not truth for an entire country. At the same time you can't NOT acknowledge the data. While it doesn't paint YOUR personal picture, it certainly tints the reality that you also live in, as does your single data point.

      Poll: Does your truck have the rear window leak?

      By ShotgunZ71 · Posted

      Glad you had success with it. I did as well, but about 5-6 months later it returned. Tried again, same result. This was after the dealer made several attempts and never even got it to slow down.

      Will not stay in Reverse

      By TheGeek · Posted

      I have a LTZ and it has the shifter in the console, which I like, but, every now and then, it will not stay in Reverse. I go through all the motions, hold the button in, push the shifter forward and watch the dash.  The big red R comes on and also the back up camera.  Then, it just pops out of Reverse with the shifter all the way forward.  So then the game begins.  Back and to Drive, Reverse.  This goes on 8 - 10 times. Very frustrating. Had it back to the dealer and they replaced some kind of computer, but it is now happing again. It is so bad, my wife will not drive the truck, she is afraid of being stuck somewhere.    Anyone else with this PIA problem?

      I see where you’re going and I can appreciate that. Statistics can be misleading because of the word average. They say statistics show the average cost of a new vehicle is about 50k. The average monthly payment is close to 1000 dollars a month. That’s statistics for you. I know very few people who pay that.
