Steering Knuckle Spindle problems of the 1999 Dodge Neon

Damage to left side of vehicle. No safety defect mentioned in summary.

I was stoped at a stop sign. Pulled out on to another street. Had to swerve to miss another car. Went to swerve back my car didn,t come back. Cliped curb and had to pull in to parking lot. Checked car on passager side. Found a flat tire and broken spindle. Part of the spindle looked funny. Like it had been already broke. Had towed to dealership, where thier technions looked at it. They called me back said that it broke when I clip curve. And I don,t think so. I think the metel was defictive. Can't see a spindle breaking at 10mi. An hour. When there is no other damage to the car.
