Howdy. I'm not comfortable under the hood, other than to fill the windshield washer fluid. I read on another forum how someone pulled all the fuses & it fixed the issue. After studying the fuse descriptions and locations in the users guide I figured it might be the M13 fuse (it wasn't). I pulled and re-inserted about 2/3 of the "minor" fuses, starting at the far side of the box. I didn't touch the fuses that looked "more involved" if you will. Sure enough, after about 10 minutes with the provided fuse puller, I tried the steering wheel buttons again & the issue was fixed. I didn't replace any of the fuses, just pull them out (1 at a time) & put the same fuse back in...Good luck!
