2005 Buick La Crosse 6 cyl Front Wheel Drive Automatic 44,000 miles
----------------------------------------------------------------
I have a 2005 Buick La Crosse CX. Everything has been great with the vehicle since I purchased it in september of 2006. We added a remote start in November 2007. I have 44,000 miles on it, and I recently had an oil change done at a very reputable GM dealership in our area in late January. 2 days later it snowed and my dummy lights came on. *The first one is the front end of a car with a padlock inside, and, *the second one is a side-view of the vehicle with a wrench inside of it(which should be a service light). This went on for at least 2 days before I brought it back to where I had my service done recently. I have kept up on all my maintenances and I know that I am due for a big one at 50K. with the way this vehicle operates my dummy lights should not come on that soonfo the 50k. So after taking it into the dealership they looked at it and found no problems, in fact they said my car was in pristine condition. Today 3 weeks later it snowed again (keep in mind I live in Iowa where it has been snowing every day for the last 2 months). The same exact lights came on. I need some answers, because I don't want morons at a dealership to say there is nothing wrong! Please help me understand what these lights mean.
