Yes, the shrieking brake noise is covered under warranty. This is what I wrote about it in August.
We are in the 18th month of ownership of our 2008 Malibu LS.
Well would you know it--our 2008 Malibu with 15,000 miles was doing fine until the brakes suddenly started to pulsate. We took it to the dealership and their technician determined that the brake rotors had excessive “run out” (whatever that means). They resurfaced the two front rotors and road test. The tech says pulsation was better after the resurfacing but still there. They then resurfaced the rear rotors, which feel much better although not as good as original.
Also, the shrill or shrieking noise at drive-off was eliminated. Thank God that annoying noise is gone.
Both repairs were covered under warranty. When we asked how much it cost they refuse to disclose that information. Not that it matters since Obama has guaranteed all GM warranties. .

Twitching the steering wheel would be another good definition for what I'm experiencing.
It seems both components will effect handling. Sway bar components because it will affect the natural height side to side, thus affecting the alignment. Are you saying the twitching is no longer needed? Are you sure that the alignment has not been affected so that it pulls into one end of the twitch constantly. If so, watch out for when a bump or something decides to steer the vehicle to the opposite end of that twitch zone.
Hope you've got your troubles solved. With todays technology we should be able to run a vehicle to 100K trouble & defect free, except for oil, filter, and tires, excepting abuse type issues.
I've had more than vehicle where pads lasted 100K and one of them had heavy diesel motor. It seems that all could. They just have to tighten quality control.

Glad to hear it was covered, but lets evaluate this warped rotor stuff. You got a problem, you have to deal with getting car serviced, maybe a loaner or not. Inconvenience.
They turn your rotors, but still not as good as it was. They've removed metal from them and you can usually only do this once, so next time you have to buy new ones, most often not covered under warranty, unless you can prove it was their fault. Since it was covered, but still not as good, I'd demand new ones.
So, why did they warp? Nearly all of the time it is because of improper tightening of wheel nuts. Enevenly tightened or overtightened. If they tell you it is because you ran through some water, BS. That only accelerated the real cause which would be improper tightening or a bad design. Most designs are pretty standard and I know of none that have a particular issue. (an example of a design that is a problem because of design would be Tiburon clutch pressure plate. For those who don't know, this is a piece of metal similar to rotor that spins and similarly brake pads engage it as a clutch pad does. They redesigned the center mount and made it out of aluminum. Result, premature failure of components, warping, in as little as 10K. Not covered under warranty.)
It is a sure bet you've had tires rotated and/or balanced. They did not use a torque wrench to tighten, but an impact instead. That is the reason for your trouble. Make them show you that torque wrench in the tire and brake bay, not one from someone elses area or tool box.
Buy yourself a torque wrench, $20 and up, and the socket needed, ~$5. Keep it in the trunk and check before leaving dealer anytime a wheel is removed. About 10 minutes to check all nuts. Loosen slightly and then tighten to the setting of the wrench.
The cheap wrench may not be accurately calibrated, but then even expensive ones should be recalibrated periodically. If it has been, it will have a calibration sticker on it saying when and by whom.
Even if yours is not calibrated accurately, you won't likely be using it much and it would not be off by much unless you got a really bad one. The most important part to prevent warpage is that the nuts all have the same torque which will be acheived even if it is off a few pounds.

No it wasn't alignment because it didn't constantly pull to the right or left, it just twitched. lol I'm not sure how to describe it. But now there is no noise and no twitching(even though i wasn't concerned about that) and a nice new headlight, now its driving beautifully like when I got it.

You can have alignment issues without it pulling, and pulling that is not alignment.

Always when any of my cars were pulling left or right, they do an allignment and it doesnt pull anymore. and by pulling i mean if you're driving on a straight road and partially release the steering wheel and the car merges left or right; thats what i mean by pulling. and yes allignment issues could be w/o pulling, however pulling is a possible cause of allignment. allignment is the first thing to check for a problem like pulling

You may just need a break pad cleaning.

Took the car to the dealership I was told that the rotor are glaz to stop hard if they start to make noise.
#1302 of 1514 Malibu 17" Tire Pressure?
Dec 12, 2009 (9:10 pm)
I recently purchased a 2009 Chevrolet Malibu (new). The dealer swapped out the 18" wheels on my 2LT with the 17" rims from the 1LT. The tire pressure decal on the inside door, however, is for the 18" rims. What is the recommended tire pressure?

Same pressure you have been using before on the 17 inch.
