NHTSA Complaint #11543046 — 2022 CADILLAC CT4

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 this has happened to me, the first time was 4 months ago and the Cadillac dealership already tried to fix the problem by replacing a brake control module. Clearly they did not fix it and now I do not feel safe in the vehicle. The problem is not easily reproducible as it comes on randomly while driving (I was literally cruising in 5th gear). My car is a manual transmission if that makes a difference, so the e-brake is pretty vital. Uploaded are pictures from 4 months ago when the problem first happened and I was stopped at my house. The last picture was from yesterday while I was driving and the issue re-occurred. I have dropped off my car today at the dealership for them to look at again.
