2000 Jeep Grand Cherokee steering problems

Driving with my daughters to the beach when suddenly my steering wheel froze as I was along a winding road. Towed truck to a mechanic who diagnosed that the gear box was broken at that point he repaired the gear box. Approximately 1 week later the same exact thing except that the truck caught fire, again towed the truck back to mechanic who replaced the gear box. I thought I was going to die when I experienced my steering wheel freeze and the fire was extinguished quickly so minimal damage was suffered.

Summary: vehicle description: sport utility vehicles. Some steering gear units were assembled with internal end-of-travel-stops that missed the heat treat process, resulting in soft internal travel stops. Consequence: this could result in sticking, binding, or seizing of the steering gear there is already a recall on the 200o jeep grand cherokee for the steering box. I am having this problem as well. As a result I drove off the road last night going around a corner.
