Hello I’m trying to figure out what’s going on with my truck. I been losing power steering when parking the last couple of month. The worst part the other day I was driving on the freeway going 70 mph and my stereo went dark and got alert power steering disabled driver with care. This happened for about 2 to 3 seconds it was a little scary. Has any one had this issue. Where you guys able to fix it? I don’t really want to get rid of my truck but it’s a little scary when you have your 3 month old in that back and this happens.
