Lately I have noticed that my power steering seems almost go out when I am braking and turning. What I mean by power steering going out is that the steering get much heavier as though power steering is just barely assisting. This is on my 07 Tahoe if that matters. Thanks

 

We have similar symptoms on our '07. Took it in for service last weekend but the dealer couldn't duplicate the problem. My wife notices it most when pulling out of the driveway but it is not all the time.

 

I have experienced this too but onlythe few times Ihave it in4 wheel drive. Now that you ask the question, I wonder if it is normal too.

 

I guess I am not going crazy afterall. Mine comes and goes as well. I am going to see if I can "make" it duplicate the problem on purpose this afternoon.
