The electronic brake control module, break retainer, brake master cylinder and brake valve all failed. I was driving to lunch and coming down a hill when multiple warning lights turned on as I pressed the brakes. I had almost no braking power as I approached a stop sign that lets you enter a highway almost causing me to drive through the stop sign and into cross traffic. I had enough bearings to down shift it and slow it down enough to stop. If I have went through the stop sign, it could have been a fatal accident. The vehicle is at a GM dealer…

A few days ago while driving (45mph), my 22' 4BW dash lit up like hell and I lost power steering, brakes, went into limp mode. Restarted the vehicle, all was well. I did almost take out the Mini Cooper in front of me, with a 'Baby on Board' sticker. Don't even want to think about that. I have a service appointment scheduled for next week and I'm not driving the vehicle until then. Please review the following thread on the Blackwing forums where over 7 different people experience the same issue within 7 days of each other. https://www.cadillac…

Owner report 11543046 · 2023-09-06 (September 6, 2023)
While driving in normal street conditions, the dashboard lit up and all the lights came on. Traction control, stability control, check engine light, tire pressure, brake, ABS all lit up. The digital dash showed two errors: 1. Forward Collision System Unavailable and 2. Steering assist is reduced, drive with care. I noticed that steering became much more difficult and braking was extremely difficult. When coasting to a park, my car would not engage the e-brake unless I shut the car down at first and then re-started it. This is the second time th…
