Towed to Dealer After Software Update

We are still dealing with intermittent backup/360 camera failures so the truck was at the dealer for them to "investigate".  We picked it up on Friday so we could use the car for the weekend, wife stops at the sitters house to grab our youngest - apparently the truck said an update was avail and should take 5 min to apply.  Now before we start educating on all of the reasons to not hit apply when you aren't even at your house, I agree (and now my wife does).  So here is a warning to anyone out there who doesn't quite agree yet.

 

She hit the update button, came back out and the truck wouldn't start, radio and other electrical things seem to work fine.  Hit start - nothing.

 

Called the dealer that we had just left, they told us it was quitting time and there was nothing they could do (that is another issue altogether.). Since we needed to get this vehicle out of this persons driveway we started a roadside assistance call and a flat bed soon arrived.  I along with roadside assistance tried to get the truck started for an hour or so, no luck.  It would "remote start" via FOB or on-star but any attempt to activate the truck it would turn off.  So we proceeded down the path of a tow.

 

The situation was made more difficult in the fact that the driveway was steep and required a hard turn - so the wheels were turned hard and the steering column electronically locked.  The truck also would not go into neutral all attempts were met with an error to the effect of this shift cannot be made in this condition.  The flatbed driver pointed out what looked like a small crash/collision symbol so he thought maybe the truck thought it had been in an accident.

 

On to the tow...As he was setting up to tow the truck I asked how he planned on getting it onto the flatbed.  His response was to drag it, which was better then when I asked how he planned on getting it off the flatbed - shake it.  Now there was no way I was going to watch a truck with 6k miles on get dragged or shaken off of a flatbed I told them there had to be a better way.  Long story short we were able to locate a "repo" style truck that could lift the rear wheels, and then put dollies on the front.  This worked great for the 2 mile tow to the dealer - although it cost me $200+tip.  I will try and get GM to compensate - I am not holding my breath.

 

So thats where we are at, truck is at dealer for them to look at on Monday.  We are down to one vehicle as the dealer doesn't have anything for us to use.

 

Whats the point of this post?

 

Please dont apply software updates to your vehicle unless you have a plan - future updates for us will be done by the dealer / at the dealer.

 

Honestly as much as we love the look / drive of this truck I am really questioning the long term life of this truck for us.

Dealer said there was a checksum error with the steering module.  Re-flashed and everything magically started working.  Hopefully getting reimbursed for the towing from GM will be half as easy.  
 

Careful with those updates!

I am scheduling a reflash of my ecm since i purchase a cold air intake on my 6.2Lfrom another dealer and installed it myself which requires it. I am asking another dealer to reflash, fingers crossed.😎

2021 Tahoe HighCountry. Cold Air intake kit, 

 

Just came from my dealer and they were not given permission from gm tech line to reprogram for GM cold air intake performance filter install, because it was not ordered with it. VIN # must show that was purchased from the manufacture and installed when built, BUTit’s a LPO so dealer installs upon delivery  to dealership before selling it.

Sounds crazy but the parts guy showed me that they were not allowed to order or sell it over the counter, I purchase from GM warehouse suppliers!

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.

      Ac not keeping up

      By Aimatdeer · Posted

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
