I have (on my 2016 Cadillac X.T.S. Platinum) front and rear automatic breaking according to the build sheet, Owners Manuel, etc. The rear works great and I love it. However, the front does not work and the dealer does a political song and dance and says it works correctly but will not demonstrate it to me. The dealer says it is suppose to warn me. However the build sheet from G.M. clearly states front automatic breaking, as well as the owners Manuel.
Cadillac service is of not help.
