Took my 2004 Sable to my dealer and found out that the inertia switch was not the problem. The problem was the computer had a glitch and updated information was downloaded into it and we're told we will not have that problem again. And guess what No Charge!
The Ford Dealer in Victorville, CA still states because the I-15 road has construction work being done that caused the switch to turn on. I guess all streets in CA and NV are is good shape, no pothole, ha!
