Steering wheel became inoperable while vehicle in motion, vehicle shut down multiple times while driving causing all loss of power to vehicle, accelerator stuck and fuel shut off when going hard on brake did not work requiring snit into neutral, many other issues. Taken to dealer for repair many times in service over 40+ days since November 2016. Not safe to operate. Cue screen replaced muriople times as well because of electrical issues and even air conditioning switching to heat, windows randomly rolling down while vehicle is parked in a parking lot, speedometer goes off and then comes back on while driving. Too many issues to name, GM/Cadillac has refused a proper repurchase of the vehicle and is stating they want a lawsuit brought against them in order to give a fair settlement as they are wanting me to pay larger than normal depreciation on a non-working vehicle in a repurchase agreement. These issues are life threatening and they are not wanting to note the vehicle is a lemon and actually sell it to another customer. They are now advising (GM executive office) the dealer to put that they are "unable to duplicate customer concern" on all further service visits should I return however I am not driving the vehicle because of safety concerns. This is not solving life threatening problems but actually covering them up. Come to find out they even serviced the vehicle prior to my ownership of purchasing the vehicle as new that they preformed service on some of the same electrical problems which I was having.
