Serice Steering Column Lock

[txat4]

1077 miles on AT4 and just got message.

Same with my dads 19.

Had my AT4 serviced today and they reprogrammed BCM according to service bulletin # PIT5651B.  This also supposedly fixes the climate control showing off on the screen when it's on.

Same message on my 2019 AT4 comes on when I turn the truck off. Took it to the dealer and they replaced the module and reprogramed it. It was fine for a few days and its back on again. I guess I will be taking it back.  Service writer acted like he has never heard of it.

This happened to me 3-4 days ago. About 1400 miles on the truck.  (2020 Silverado 3.0). While waiting in the 40-minute line to exit the parking garage at work — was on the decline from 3rd floor to 2nd floor. I put the truck in park, and could not get it out of park when the line moved again.  No amount of rotating the steering wheel (it moved freely) helped. I shut off/restarted the truck. Still stuck. (Started to get nervous at this point). I released the brake pedal and pressed it to the floor. No good. 
 

Finally, I turned on the parking brake, that freed it instantly (also, I prayed). Thank God, otherwise there would have been a massive amount of teed-off people stuck behind me waiting on a tow. 
 

There were no warning lights. I had remote-started the truck with the key fob (not the app). 

 

Has not happened since, but this morning, on start up on level ground, the “service steering column lock” warning appeared on the DIC for 2 seconds and disappeared. No other symptoms, just the warning. 
 

If I take it in now, pretty sure the dealer “won’t be able to replicate,” and it’ll be a big waste of time.

I got this today for the first time, didnt really seem like a big deal.

Just had this thing lock up on me again. Stopped at a light in traffic, put the truck in park so that I could pick up something that had fallen on the passenger-side floor. Stupid, stupid, stupid move. 
 

Truck would not go back into drive! Steering wheel moved freely, no amount of cycling the ignition or turning on the parking brake or pumping the brakes would release the interlock. 

 

Thought I was going to break the shifter.
 

Finally called OnStar (to see if they could offer a remedy or send a wrecker) while on hold with them, the damn thing released! After 3 traffic light cycles and several pi$$ed off people around me (rush hour). It was an awesome experience!

I had released the tilt/telescope lever and while moving the steering wheel violently around, the interlock released. 

 

Guess it’s going in for service next week. Not even 2k miles!

 

It’s a 2020, so much for waiting for them to work out the “first-year bugs” LOL.

2020 Trail Boss LT. 750 miles. Just got this message

[Jrodpic]

Made an appointment to take the truck in, of course 2 days before the appointment the message disappeared on it’s own and hasn’t come back.  Hope this isn’t a reoccurring issue...
