Auto theft device sensor not allowing van to start at times.

Same problem here........ you can unplug the alternator fuse located in the fuse box under the steering wheel to the left then plug it back in. Your vehicle will start everytime. This is a hard reset but works everytime. Hope this helps. Also call kia customer service and complain so they will recall the defective fuse box. 1-800-333-4542

i just had to do this with a nissan maxima--not sure how i did it--but plan on getting a new ignition switch--they dont cost much and acually easy to put in--its in the wiring harness under dash on the steering column--take to a dealer --they going to charge arm and leg---but if you want dealer to do---take to a kia dealer--just saying
