'22 Sierra 1500 Denali, P25A2 problems...

[JD Arkin]

Just picked up a '22 1500 Denali with 3.0 DMX...75 miles on the truck and get the "Service Brake Assist" warning, ECU stored P25A2.  Took to dealer, they followed GM diagnostic tree, reset ECM and cleared code...ran vehicle without incident until yesterday (about 400 miles now) and ECU stored same code again...it's back at the dealer.

 

wondering if the electronic parts shortage has GM sending vehicles with older/non-flashed BSCM units out the door...?  in any case, concerned and disappointed that an $80K pickup truck seems to be less reliable than the $60K pickup truck from three years ago...

 

anyone else continuing to see this failure mode on newer GMC Sierras?

Quick update...Service center is replacing the Master Cylinder + BSCM (I think this is an integrated unit now)...part on backorder, so they reset the DTC and gave back to me to drive until it comes in.
