While driving car jumps out of gear causing rapid deceleration, loss of traction control, stability control, power steering, and brakes. when this happens the instrument cluster looses any indication of gear selection, and car must be shut off and restarted several times to regain controls once parked. GM/Cadillac is aware of the issue since they have a TSB relating to the fault code, but no recall, even though this is a severe safety concern. It has happened several times at multiple speeds, highest of which was about 45-50 so far. Have had it into shop 4 times. They have replaced a detent, which did not fix the problem, and internal mode switch twice within approx. 2-3 weeks apart, neither time has fixed the issue. Now they are wanting to replace the Transmission control module, which I have not had done yet since I am not confident in their ability to correct the issue and the cost is well over a $1000.

Currently looking into legal recourse since I have a vehicle that is pretty much a lemon and not safe to drive my children in. Cadillac has refused to grant a goodwill repair even though the issue was addressed 3 times under the CPO warranty. I have been looking online and have seen several recalls for similar issues but different model years. Not sure how rapid deceleration, loss of power steering and braking does not qualify as a recall necessity. I have opened a case with GM and for some reason it keeps getting closed. Twice now in the last week I've had to call back and reopen the case but the district service specialist has not contacted me back since our first call.
