I disagree that this fix will 'end after warranty period'. NHTSA should follow-up!
Are you experiencing brake issues with your car or just inquiring about the possible recall? You should be able to see any recalls/updates for your car in the MyCadillac app. Have you taken your car to the dealer service department? They should be able to address/repair any issues and verify whether your master cylinder is included in the GM Service Update. Good luck to you.I sent an email on xt4 2025 possible break issues and I am getting no help
on update n252494220
