“After reversing approximately 6 ft in my driveway I put the vehicle in drive and before taking my foot off of the brake the passenger side airbag deployed in the front seat where my 14 year old was sitting. No accident, no potholes, not even moving, no reason at all the airbag deployed.”
NHTSA complaint #10523504, filed 2013-07, 130,000 miles“My 2004 Mercury Mountaineer has a crack in the lift gate that appeared a year after I brought it from the dealership. At first I thought it was something I might have done but every one I ran across has the same identical crack in the same area. People I spoke with said it just showed up one day. Is there a recall on this defect?”
NHTSA complaint #10256331, filed 2009-01, 56,000 miles“I was driving on the highway at about 55mph in a 2004 Mercury Mountaineer and suddenly both side curtain airbag deployed. There was no accident, no impact, no potholes, no veering or running off the road; just driving and it happened. Scared me half to death. I was able to compose myself well enough to not wreck. Furthermore, there was no warning from the dash for the airbag to inform me of any malfunctions or problem with the airbag sensor or module.”
NHTSA complaint #10382910, filed 2011-02, 170,000 miles“Driving at apprx 50 MPH when suddenly both the driver side and passenger side air curtains deployed!! There was no accident. No impact from objects. No pot holes or road hazards. No warnings just a loud bang and the next thing I knew I was hit in the head by an airbag!! I had no idea what happened. I thought I was struck or shot at first! I was fortunate to keep the car under my control as I was on a two lane surface street in morning traffic. I am currently in contact with ford to attempt resolution for the defect. …”
