“Purchased a 2009 Buick Lacrosse in feb 09 for my wife - at various times about 6 events have happened all together with a strong alcohol odor coming into the interior. The smell is strong and causes her nose, eye and throat to burn. This past weekend - she drove it to va beach, va with family and it happened twice on sunday - june 7, 2009. My concern is if the build up of this strong alcohol odor comes into the car - can the odor cause a fire? I have had it back to dealership where purchased and they said until it happens all the time - there is not a thing they can do about it. …”
