Service Brakes problem #1

When braking — both at low speeds and when slowing from highway speeds (40+ mph) — vehicle feels like engine revs and is still pushing against the brakes. Requires very firm pedal pressure to hold car in place; if brake pressure is eased, vehicle surges forward until it finally settles after several seconds. Concern is intermittent but repeatable. I had a near collision on 10/3/2025 due to this issue. I have been in constant contact with the dealership on this, including the service manager, as well as Cadillac care. The dealership has test driven the vehicle several times and has been unable to replicate the problem. However, I do have an audio recording of the engine’s idle speed at various points during one incident.

Service Brakes problem #2

At a red light in traffic, it suddenly shut off the engine, emergency brakes went on, multiple warning lights were on (low bat, low fuel {full of fuel}, lower passenger window, etc. . ), totally immobilized itself by not being able to start the car or push it with the brakes on! 81 year old female driving and if the car did this at highway speed it could have been a catastrophe! it appeared everything else in the car was working but had 'self immobilized'!.
