I am new to this forum, but couldn't agree more with the comment about Chevrolet wanting dealership performance feedback but no feedback on the actual car. Bad move on their part! I have a 2004 Malibu LS and have also had problems with my steering column and a thumping noise, primarily when I turn left. The steering column was replaced once while the car was still under warranty (I currently have 46,260 miles on the car and it is not quite 2 years old). I have taken the car back to the dealership twice and have been told that the thump is just a "flaw in the design of the Malibu." I'm not satisfied with this answer, but don't want to keep having the steering column replaced, especially if Chevy won't pay for it.
I've also HATE the headrests. Can they replace them at no charge or am I out of luck because of the warranty issue?

That's how it should work but if you look at the thread of this discussion and in particular, post# 2615, you will see that something funny is going on here. It would seem to me as if the engine is getting too much fuel despite the computer control. It is also possible that the injectors are leaking causing flooding of the engine and that is why flooring the gas pedal allows it to start. I don't know. It's always difficult to diagnose problems from afar. I don't know at what point of the gas pedal travel the computer switches off the fuel.
I think its variable. By trial and error, I was able to press half-way down on my pedal and it took the engine longer to start, and it seemed harder to start, but it may have been coincidence.

"My '05 Maxx makes a lot of popping and crinkling noise from the manifold thru the converter and tailpipe assembly when it is shut off and cooling down. This I can understand and accept. However mine makes the same noises when there is any change in sheet metal temp due to different operating conditions; such as when idling at a light, pulling a hill, coasting down a hill etc. Needless to say it is extremely annoying. Has anyone else had the problem and what was the fix?
Dealer ofcourse says this is normal---BS. "
I'm having this "problem" as well... I figured it would stop as the car broke in, but it is as loud as ever w/ 5100 miles now. I drive my Maxx pretty hard, so I know I get it hot fast, but the noises do seem extreme. I still love this car though. I still look forward to the drive home...

I can't describe it except to say it is a "thump" that you can hear and actually "feel" in the steering wheel when you turn (mostly only when I turn left). Mine started out hardly noticable, too, but seems to be getting worse.

I have a 2004 Maxx LS and have not had the thumping problem. I'm no expert, but problem may be caused by the steering gear pre-load adjustment. While the power assist is electric and built into the steering wheel, the steering gear is a standard manual rack and pinion system. There is TSB for this, but it says it only applies to GM Chevy dealers in Mexico. It's TSB 04-02-32-003, issued April 2004.
The TSB says - Some customers may comment that while driving over certain rough road conditions, they hear a rattle noise from the front end of the vehicle. Some customers may also comment that they feel clunking in the steering wheel while hearing the noise. This condition is more likely to occur only when the vehicle is hot and will go away after the vehicle cools down.
The fix is to remove and install a new plastic adjuster plug and retorque to spec.
#2634 of 3823 Measured RPMs at Different Speeds
Nov 10, 2005 (9:30 am)
60 MPH: 1800 RPMs
65 MPH: 1900 RPMs
70 MPH: 2050 RPMs
75 MPH: 2200 RPMs
80 MPH: 2350 RPMs
85 MPH: 2500 RPMs
2004 Malibu Maxx 3.5L V6
Note: to obtain these numbers I set the cruise control at these speeds on a level highway and held that speed for about a minute to ensure that the transmission was satisfied with its configuration (no TCC changes, etc).

mine isnt in the steering wheel at all..that is smooth as glass still..at first thought it was a bearing but had that checked..and wasnt the problem..so will just live with it.....mine is so slight you can only notice it with the windows up...no fan and no radio going....just one of those little things you get to know about your car I guess

some have simply turned the headrests around....out of warranty...dealer will probably not touch the issue...
to be honest..I find them the most comfortable ones I have had in all my autos....they actually support the head vice the neck..and allow me to sit straight in the seat and rest my head back....Im not one to laid the seat back..and make it a lounge chair.....
