Car Will Not Start problems of the 2010 Buick Lacrosse

My Buick Lacrosse was handling just fine until I put a heavy piece of luggage into the trunk. I got back in the car and it wouldn't start. A message was on my dashboard saying there was a power steering problem. I was at the airport, so a tow truck driver was on the scene within minutes. The tow truck driver jumped my car. He handed me the trim cover that covers the battery. I'm not sure if he took it off, or whether it came off when I put the heavy suitcase in the trunk. I put the trim cover in the back of my car and drove off. The car then stalled when I put it in reverse to back into the driveway. It wouldn't start again, so I jumped it. It worked and I drove to my mechanic. Mechanic said my battery was fine. They checked the error messages. They couldn't figure out what was wrong so they sent me to a dealer. The dealer couldn't figure out what was wrong and said to come back if it happens again. For about two months the car would randomly not start or stall. Several days could go by with it working just fine. At first, when it stalled it was only when I had just started the car or put it in reverse. But then the vehicle stalled while I was driving on the interstate, at the top of a long hill, in a construction zone. I was able to coast down a half mile or so until I arrived at an emergency pull off zone. The power steering went out so the steering wheel was tight but workable. After pulling over, I tried starting the car again but it didn't work. I had a self jump start kit, and was able to jump the car again. It started back up and seemed like nothing was wrong. But about five minutes later it stalled again. Fortunately, I was by another emergency pull off. At this point, I put the trim cover back on the battery. And the car has worked fine for several months. The car should not start and then randomly stall if the trim cover is off.

I moved my car out of the driveway so my neighbor could plow our driveway. He said he smelled something. I parked the car across from our driveway put it in park, pushed the button to shut the car off, as my vehicle filled with smoke, I grabbed the door handle and jumped out. My neighbor ran to my vehicle telling me to disengage the hood, I complied. Flames jumped up and out from the passenger side of the car under the hood. He threw a lot of snow on the fire to extinguish the flame. We inhaled fumes. Car will not start. After this, my husband came out and my neighbor explained and my husband unhooked battery.

I moved my car out of the driveway so my neighbor could plow. He said he smelled something while I was in my car across from our driveway. I put the vehicle in park, pushed shut off/turn off button, vehicle instantaneously filled with dark rolls of smoke coming from the passenger side from the front of the vehicle under the hood. I grabbed the door handle jumped out. My neighbor came running telling me to disengage the hood, I complied. Flames shot up and out from under the hood as it was being released. He threw a lot of snow on the fire extinguishing it. We inhaled the most obnoxious fumes from any automobile I have had the displeasure of having in my company. Car will not start. After this, my husband came out to see what all the yelling was about. My neighbor explained it to him and he unhooked the battery. The car is still parked at the scene of the fire. Today is 2/22/2014 and no insurance adjuster has been here yet. Our town fire department was called and the fire chief assistant came the very day incident occurred and filled out a form, I contacted Buick and I have a claim number and am awaiting further contact from them. Our town highway department placed cones around my vehicle.
