I’ve got a 2010 enclave that I’ve owned for about 4 months. I’ve been having problems with my power steering, I’ll be driving and going to make a turn and lose my power steering and make another and it will be fine again. I checked the fluid reservoir and it is just below the max line. I don’t hear any whining. I’m wondering is it a common problem and does anyone know anything I could do to resolve this without doing to an auto shop.
