It could be normal. My '03 Malibu has a good deal of annoying
suspension-related noises too. Others in the Malibu NG complain about the
same thing. Like you, I came over to GM from 16 years of buying Chrysler
products. I did so to stay with a US product after Daimler bought Chrysler
making Chrysler German owned now...not from any problem with the product.
The added annoyances of the level of overall noise with the GM product I
bought though took some getting used to...not sure I am used to it yet. GMs
silly answer...make the radio volume level automatically increase with
greater speed. Seems to me it would have been easier/cheaper just to make
the car quieter in the 1st place since the competition seems to be able to
do it. <sigh> What doesn't help is that my wife refused to change, so when
ever I need to borrow her '03 Stratus she recently bought, is soooo smooth
and quiet in comparison I start back at ground zero when I get back into the
Malibu again!!! :-(
I would have the dealer (or your mechanic) check things out just to make
