Problem with my 2005 Chevy Malibu
Mileage = 30,000
Engine size = 4 cyl.
Dash lights =
Power Steering
GM tech = Any
question = I was driving down the interstate this morning and the power steering message
came up on my dash as my steering tightened up. After I restarted the car it began
working again. Why does my car do this. Is this normal or am I going to need to have
something replaced?

JK:
First of all, no this is not a normal condition for the electric steering system. The power
steering light and loss of power assist indicates a problem. There are a couple of things
that cause this.A failing sensor in the steering column, a problem in the steering control
module, or a voltage problem between the alternator and ignition coil assembly (a service
bulletin applies).Either way, the system would need to be scanned for computer codes.
The stored code(S) is the key to determine where the problem is.

This system requires a scanner that can read the power steering module, body
control module and ABS module to diagnose.
There should be codes stored in the steering control module. It would be impossible
to guess. Could be the steering column assembly-which also houses sensors, or a
binding steering gear.
