Recall N202317390 Brake System Control Module Internal Fault

[jna97]

Just was notified yesterday about recall N202317390 Brake System Control Module Internal Fault. Dealer said it takes 1-1.5hrs and is a brake module reprogram. Details below:

“Certain 2021 model year Cadillac Escalade, Escalade ESV, Chevrolet Tahoe, Suburban, GMC Yukon and Yukon XL vehicles may have a condition in which the brake system control module (BSCM) may set and latch an internal fault in the module’s on-board diagnostics (OBD) buffer. When the fault is present, no malfunction indicator lamp (MIL) is illuminated and there is no driver information center (DIC) message. If an over the air (OTA) software update is pushed to an OBD module and the customer accepts it through the Infotainment system, the update will fail because the presence of the active fault will block the OTA update. The customer may notice that the OTA update has failed with an error message on the DIC. This fault is not visible through dealer tools.

Repair Description:

Dealers are to reprogram the BSCM.

I am sure some of the new 2021 model owners here are glad for this info. Thanks.

The dealer told me there was no fix yet. Is that wrong?

 

[OR VietVet]

Sounds like either the dealer was swamped and wanted to put you off or the reprogram steps had not come out yet.

We had ours in for the wire to airbag being short and dealer told us there was a software update but that GM hasn’t sent it out yet. That was Thursday.

Actually got mine done today. The in-person advisor told me when I checked it in that the first software update didn’t work and actually made things worse. They got a new update later this week and it has been successful. Took about an hour.

Yep. It's out there now.

 

[SAdude]

Got mine fixed last week

 

[Bigmanny]

Had mine fixed while it was in for exhaust issue this week.

Is this an urgent recall or can I do in a few weeks?

Don’t think it’s urgent, but since it is brake related I went ahead and did it ASAP.

I took my 2021 to the dealer yesterday for this, 3 hrs later bc he said a step was not posted in the instructions and he had to call to get the missed step. Today I was driving, I stopped on a hill, did not put on the parking brake, but it auto comes on. Got back in to leave, parking brake would not release. Flashing red PARK and ALSO flashing orange wrench with P. Called the dealer, they said to call GM roadside. 3 kids in the car, 23 degrees outside. Call roadside and all it says is to download the GM APP to access roadside. No wifi. I tried everything, reverse, N, D, hold the P button, don't hold it. Wondering if it had to do with the refresh??? It's back at the dealer.

Wow...hope everything checks out, I’d be furious (I have 4 kids, I know your pain too well LOL)

On a side note - I had the BCSM recall done last week (still waiting on airbag recall harness to come in for that recall)

I have noticed since the programming, when I put my XL in reverse, it no longer begins to roll on its own, I have to give it gas to start reversing. I’m not on an incline or decline either. Just thought it was strange

The concerns just keep piling up. I am glad now the deal fell thru for the 2021 Z71 and I have my 2005.
