Hello, I have a 2012 gt coupe with 27,000 miles I picked up as a project car. One of several issues is that the steering wheel buttons do not work, horn works. I have checked fuses and all appear good. Everything keeps pointing to clock spring. I am a former helicopter mechanic so replacing the clock spring does not scare me, but don’t want to go that route if not necessary. With only 27000 miles, hard to believe it is the clock spring, but you never know. Any suggestions
