NHTSA Complaint #11590602 — 2009 DODGE GRAND CARAVAN

I had a flat tire (drivers front). I Parked on a level parking lot. I put bricks behind other tires to prevent movement. Next I loosened lug nuts, I then removed the spare and original equipment jack. I began jacking the car up with the jack in the area indicated for jacking by the instructions. The tire was off the ground. I was beginning to spin off the lug nuts when the car dropped with a brrrrrt sound. The main screw in the scissors jack pulled through the threaded nut on the end. The jack was still upright but the screw threads failed. No one was hurt but the potential is high for the jack to fail suddenly and without warning. Note the van was not occupied or in any way loaded. The second picture attempts to show the screw threads deformed after pulling through the nut.
