I have 2013 Cadillac ATS 2.5 Standard with 800 miles. It trembles in idle during a red
light for example .My dealer tried to fix with a software bulletin however it still has a
minor trembling problem that is annoying and makes me wonder do i have a Cadillac .
I can't believe that Cadillac is not aware or able to fix this flaw with the rough idle .
The vehicle I think has awesome styling and does have a quiet ride but the trembling
idle give the whole car a bitter taste. Any Else can be done????
