I have a 2011 Suburban. I've noticed sometimes when doing turns that require a good amount of turning the wheel (very slow, like when parking), sometimes the power steering lags a little bit. It almost feels like there is no power steering sometimes.

I know the pump is still engine driven, so it doesn't act up when moving. Just at idle making big turns.

Anyone else notice this problem?

 

You might check the power steering fluid level.

 

A power steering pump is responsible for both storing power steering fluid and supplying the Suburban's steering components with fluid. Check your power steering fluid. Over time, the seals and bearings within the pump break down, resulting in power steering fluid leaks. When this occurs, the proper repair is to replace the existing pump.

 

Its been doing it a while. It only has 33k miles on it. I asked robbins chevy and they said just give it gas! Ha! Thanks for the great advice!

 

The power steering fluid is full. It's usually going from full one side to full other side. When heading to the other side, it feels like there is no power steering anymore! Strange!

Shouldn't be like this, but not a new problem either. I talked to Robbins earlier about it and the mechanic just said to give it gas. Ha! thanks, I should've thought of that!
