NHTSA Complaint #11648746 — 2015 CADILLAC SRX

This vehicle has had an intermittent (for a few years) issue with all of the warning lights (ABS,Stabilitrak,Parking Brake,Steering) coming on when starting. If you tried to drive it, you would have no power steering causing the vehicle difficult to handle. This would not happen every time it was started. We took the car to the local Cadillac dealership and were told nothing was wrong and it was just the system going through the electronic check system and to just not put it in gear until after the lights cleared. That actually did work sometimes. Recently, it came off and would never go off. We took it to a shop that does other work on other vehicles for me. He found that the Electronic Brake Control Module was bad. He tried to source a replacement one but found that it was discontinued with no alternate part. He did find a used one which we are waiting on to be delivered and then installed. My first concern is that if this happened when my wife was driving she could lose control of the vehicle causing an accident. My second concern is how can GM discontinue a known problem (I found multiple forums discussing this issue) part with no replacement. The vehicle is 10 years old with only 75K miles. I have read this has been an issue for quite a few years.
