Geez! It’s always something isn’t it! Yes, After receiving the email I checked my rewards to find the $250 added to my account.

Got this email today…. Kudos! This is how to treat a valued customer.

That’s great! Thanks for the updates.

If it has the wrong connector on it, the dealer f’ed up ordering the part! I was serious when I said prior, to tell them to take the part off something on the lot. Like Steve-2019 suggested, I would try to see if the part can be located elsewhere.

Wow! What a mess! Your dealer doesn’t provide a loaner vehicle? They should have pulled a module out of something sitting on the lot.

My dealer got me in for service sooner than expected. Determined that the TCCM (transfer case control module) was shorted internally. Luckily they had one in stock and the repair was completed in two hours. No more OTA updates for me!!!

Just got a call from my dealer. They are reaching out to affected customers hoping to inform them about the faulty update and to not perform the update. I was assured GM has a fix with a new update. I have an appointment for Thursday.

Not what I was expecting! Can you elaborate on the undriveable comment?

Right! The truck still drives so I’ll keep using it until dropping at the dealer. Not happy with how it’s been handled thus far. Funny thing is it was just there for an oil change the day before. Not surprised by this software issue. New vehicles are computers on wheels nowadays. Truck has been perfect until now. Glad you are getting your issue resolved.

Performed the update last night. Started the truck this am. Update failed notification on the infotainment screen. Parking brake applied, Service 4x4 system, forward crash avoidance and 4x4 icon light on. Could only get the brake to release by placing trans. in drive, apply brake pedal and press e-brake button. Dealer can’t look at it until Thursday, 10/5. 2023 Silverado 1500

Looks like it’s your tires.

From the owners manual......

I had a similar issue. Could not join the WiFi network. Called OnStar a talked with a tech. Tried numerous attempts to diagnose the issue. Multiple resets etc. He was stumped for a bit as to why he could not resolve the issue. On a whim he decided to have me delete the network from my phone. He then remotely changed the network password and had me join the network using the new password. Bingo! It worked. No issues since.

225#. Mid to upper posterior thigh.

Did the same. I used double sided tape to mount the sensor motors to the bottom of the seat pan thinking maybe the vibrations would be felt. Nope! So I turned them off. Bottom line, the seats could and should offer a much higher level of comfort. Unless they redesigned the seat bottoms on the ‘21 they are not buried at all. I believe they sit in a recess and the only padding is the upholstery. When I removed mine, I pulled them out through a small hole in bottom of the seat foam. The hole is for the wire and connector to pass through but large enough to remove the sensor motor. I made up two plugs from some closed cell foam and inserted them into the voids.

I captured this from an online window sticker. Check out the last line.

GM must have had a pile of GMT800 ISS’s sitting around and decided to use them up. Can’t believe this issue is reoccurring! WTF! Thanks for confirming and sharing your video. BTW, you didn’t mention this or show it in the video, but you need to be careful when removing the shaft so that the steering wheel does not spin freely. It could damage the airbag clock spring. I also noted this in the video comments.

There are some available updates... https://media.chevrolet.com/media/us/en/chevrolet/home.detail.html/content/Pages/news/us/en/2020/oct/1007-silverado.html Beautiful truck though.

Ahhh yes! The infamous GMT800 I.S.S. (Intermediate Steering Shaft) issue. IIRC, first recall was to repack the spline with grease. That would tighten up the tolerance for a while and the knock would eventually return. Second recall was to replace the shaft with a revised part. When didn’t work, back to repacking with grease. The steering on my 2020 feels odd at times but overall performs well. I have the digital steering. Seems to have very, very light effort on center, possibly a quarter inch or so of play left and right off center, hard to tell. The odd part is that the truck tracks very well at all speeds. No wandering at all, tightens up nicely as speed increases. I have noticed a few instances of very slight knocking felt through the steering column. Approaching 1000 miles.

AT4 trim is a top seller right now. When I bought my Denali on 11/2, it had an additional $1000 rebate over the AT4. You are also going to be limited by current supply. Sellers market to some degree. I purchased from Robertson’s in Wareham. Been in business a long time. Family owned and operated. Exceptional buying experience from start to finish. Deal included my trade-in. No BS, straight forward deal. They honored the First Responder discount that I qualified for while others would not.

New truck in the driveway! Took advantage of some great incentives as well as excellent trade equity. What an incredible truck!

Probably butyl tape.

Wow! Great info from you per usual. Thanks for the links I think we need to put together a "go fund me" account for all you have done and continue to do.

I totally agree with all of this. I wonder how the previous GMT-900 body mounts compare dimensionally. Will they fit?
