The oproblem is that the Malibu always felt like this, even before they added the electrical assist. Your problem is with the way Chevy thinks the steering system should feel, not with the implementation.
I urge you to drive a Toyota with the system. It's pretty tight, maybe even more so than the Toyotas without it.
That said, I don't really like the electrical steering assist, because it is more unnecessary complexity. It _can_ make for tight steering at lower cost, but to be honest I have driven plenty of cars with no power assist at all that were great.
Too many GM products steer like ocean liners... you can turn the wheel
20 degrees and nothing happens, the dead band is so severe. Cadillac finally got this right with the CTS, which is the first Cadillac ever that steers and handles like a real car. I'd like to see the folks who designed THAT try designing an electronic assist; I think they could do the concept justice.--scott
