l leased a 2007 Lincoln MKZ two days ago. l parked the car in my driveway which had a SMALL THIN amount of ice on ONE side of it only... The other side of the driveway was dry as a bone. When l woke up the car had rolled on its own to the bottom of the driveway into my van. If my van was not there it would have ended up in the street! There is a small dent but my main concern is the dealership cannot find anything wrong with it. I am so afraid that it will happen again and someone will get hurt. Does anyone have any idea why this would happen? It is a 43,000 dollar car and the dealership thinks I am insane but l do not wanna be stuck with a 3 year lease that is going to end up hurting someone!!! If l only had an idea of what could cause something like this they would check it out. Could it be a computer or GPS issue? My emergency brake was not on the first time but l put it on and it happened again. Please help!
The car is an automatic and my driveway has an incline but l had a 2003 Mustang before the Lincoln and NEVER had the problem l am having now and NEVER had to put the emergency brake on.

Computers and GPS has exactly zero to do with brakes. If your entire driveway was covered in ice, it could happen. If your driveway does not have a steep grade, TAKE THE DARN THING BACK! Apparently there is some issue with it, I've never heard of any vehicle that is normal doing this without being on solid ice!

Unless it is a standard. Then you may want to get the brakes checked out.

Gravity sucks, yeah? Heavy cars r sometimes too strongly attracted to the center of the Earth for their parking brakes to restrain. (Of which, BTW, u have now learned the importance: the parking brake wo not always keep ur car in place, but it beats not using it & seeing the car rolled down the driveway.)

My Jeep Wrangler did this, but l could put it in first gear (manual transmission) & it would basically stay put. When the weather was bad l put a brick behind the back tire. You may not be able to get ur key out if the car is in gear: I'd ask the dealership about that too.

Ice anywhere near a tire could be very bad- try putting just one foot on some ice & see how steady u are- & on icy days, I'd move to California.
Or park on the street.
Except that l already live in California.

Well l think you are insane too. if the second time you had the emergency brake on no way is this car going to move unless it is sitting all 4 wheels on slippery ice which you said it was only 2 wheels on ice so your store really makes no sense, sorry. Maybe someone some where can back your story.

Your biggest mistake was buying a ford. Perhaps call the ford motor company. Some dealers cannot be trusted. Ask if there has been a recall on the specific model. Your GPS has nothing to do with it.

Google ''Lincoln MKZ Technical Service Bulletins'' then look to see if their is a description of ur problem. If u do not see anything under Lincoln, then be sure to Google ''Ford Fusion Technical Service Bulletin'' and/or Mazda6 Technical Service Bulletins. This will stop u from getting the run around & u can be specific by referencing their document & what the Manufacturer suggests to the Dealer as a fix. If that fails, call ur insurance agent & have a call into the Service Manager, finally, ask to do a survey for customer satisfaction & that will light a FIRE under some-body is butt!

Put a call to Lincoln at 1-800-521-4140 or lincoln.com
asap. There is a safety issue here.

Also notify the US DOT investigation group.

Try not to park on ice of any kind especially on an incline. Use wheel chocks if necessary on icey days.

There probably is nothing wrong with the car. Ice most likely formed on the ''dry side'' while you parked it. To be sure, take it to another dealer to have them check out the car.

Cars slide on even a thin sheet of ice on a slight incline. I've seen stopped cars been blown off a flat road in an ice storm in Colorado before. l personally think you are insane, my girlfriend has problems like this all the time too. And there is nothing wrong with her car.
