It's definitely a 'characteristic' of Malibus (my 97 has it), but it's not
an issue, except maybe aesthetically.

If it's under warranty, you may be able to complain loud enough to get
something done, but be advised you'll probably have lots else to worry
about! :-)

Why worry about it? I only had to change 1 head lamp bulb so far on my 97
Malibu. Only 1 burned out bulb on the entire car in over 6 years, not too
bad.

If considering a 2004, I'd at least wait 1-2 years since the 2004's are a
complete redesign and no one knows if they are any good yet.  Some that have
posted here with 2004's don't seem very happy with them...reporting problems
the dealer can't fix due to shortage of parts.

Same here on my 98 Malibu. When I was at the dealership I mentioned it. I
was told that there was probably a hair line fracture somewhere in it. For
some $400 (cnd) I could get a new one or have the globe resealed. They had a
company that did that form $70 approximately. I keep meaning to check when I
get the car washed to see if it's still holding.
