Software Build

Steiny33 · 2024-06-21T18:33:50+0000

Hello, I can’t seem to find an answer to this online. I have a 2020 GMC Sierra with software build number W119E-U148.3.4. Released on September 12, 2019. There shows some activity in update history. One says August 6, 2021: invalid argument: invalid argument. The other entry in the update history says May 5, 2020: 84817056.MNF:MIH208–00523 I am connected to my home Wi-Fi and I’ve tried doing an update. I’ve tried many other times as well. It shows me the last time I checked for an update, but I always get “no update available” message. This seems odd that the software build number for my truck is from 2019.

  So they managed to get GM warranty participation on it? Nice. The "warranty" they are telling you though...doesn't sound right. GM OEM replacement parts are only a 2 year/unlimited mile warranty, except for some select items that may have a limited lifetime (wheel bearings and a few other things) and accessories. So the cam, lifters, etc. would only have a 2 year/unlimited mile warranty from GM.

  Now there's some fancy double talk. Let me see if I get this right. The level is at the bottom of the hatching and you add a quart (because the range of the hatching is a quart) it brings it to the top of the hatching but.... it's not down a quart?

  The bottom of the crosshatch wouldn't be "1 quart low" in the published manual because the range of the crosshatch is the allowable range. The crosshatch is approx. 1 quart or liter so that when the oil level is at the bottom of or below the acceptable range you can safely add 1 quart or liter without overfilling.
