Auto defect cases can become harder when the incident involves real-world conditions common in the St. Louis metro area:
- Commuter traffic and hard braking: Failures involving brakes, traction control, or ABS can lead to multi-car scenarios where insurers argue the driver “should have” avoided impact.
- Suburban driving patterns: Intermittent electrical or sensor problems (warning lights, stalling, limp mode) may be described as “maintenance-related” even when the failure mode is consistent.
- Quick repair culture: After an accident, vehicles are often returned to shops fast. If the failed part is discarded or diagnostic data isn’t preserved, proving the defect becomes more difficult.
These issues don’t just affect what happened—they affect what can be proven.
