I  experienced a CEL about two months ago that I noted here
on the NG. It was a EGR failure. Took it to be fixed and
when I finally got it back (two hours later), the CEL was
out and  it passed the State Safety Inspection. I thought
all was well and had good thought concerning my local
dealer.
For the past couple weeks I've heard a rattle somewhere on
the passenger side. I kept thinking it was the passenger
seat I finally eliminated that seat but still couldn't find
it....till today. I had looked in the trunk many times but
never noticed anything. Today....thye battery had slid
sideways and the carpet cover was not in place. Unpon a
little more inspection, I find all the brackets ment to hold
the battery in place were inside that pathetic little spare
tire. Soooo...the noise was the battery bouncing and sliding
around.
I called the dealer today and they apologized and scheduled
me in to re-fix the battery hold down.
Damn...we pay these idiots $80 and hour for this
incompetence????
