Software problems of the 2015 Cadillac Escalade

I received a recall letter October 2018 stating the vehicle may experience a temporary loss of electric power steering. I had work done on September 24, 2018 at castle Buick for that problem. I should be reimbursed for the cost of repair that was covered by my own extended warranty. It cost me $1,037. 18 plus $170. 00 deductible, which totals $1,207. 18. I then received a letter dated November 12, 2018 from Cadillac customer assistance stating that the repair that was performed at gm was not the repair covered by the recall. The problem was for the steering. The steering wheel was snapping back when I tried to turn which was causing my wrist to become sore. It was a steering problem in the beginning, and I had no control over the automobile. Gm put a whole new motor assembly in the car instead of rectifying the problem of the software.
