2018 Ford Taurus

Components Involved: Engine Block Mounting Boss, Intermediate Shaft Bracket (Service Part # DB5Z-3K305-CA), Factory Bolt (OEM # W500131-S437) Incident Overview: During a low-speed (about 5mph) lateral impact to the front-right wheel against a curb, expected sacrificial suspension damage occurred (snapped CV axle, separated lower ball joint). However, lateral force transferred through the passenger-side intermediate shaft directly into its carrier bearing mounting bracket. Instead of the cast mounting bracket (DB5Z-3K305-B) absorbing the force or breaking, the lateral stress sheared the cast mounting boss entirely off the engine block. Engineering Flaw & Dimensions: This design presents a critical flaw in the crash load path and failure hierarchy: Improper Leverage: The 84mm thick cast bracket acts as a rigid lever against a small, brittle ~17mm cast engine block boss. Inverted Material Sacrificing: The over-engineered bracket survives the impact, transferring fatal structural damage to the non-replaceable engine block instead of acting as a sacrificial fuse. Inadequate Thread Engagement: The factory 95mm flange bolt (W500131-S437) only utilizes 11mm of thread inside the raised boss, completely ignoring 1 to 2 inches of threading available deeper within the engine block casting. This shallow engagement concentrates all shearing stress directly at the weakest protrusion. Consumer Burden: This localized failure condemns the engine block, requiring a full engine replacement under standard dealership repair procedures. This creates a severe and disproportionate financial burden for what should be a straightforward suspension and driveline collision repair. Conclusion: I request an investigation into this structural vulnerability. The intermediate shaft bracket mounting location acts as a critical weak point, actively transferring lateral impact energy into the block and causing premature, catastrophic structural engine failure.

The contact engaged the electric parking brake, and the vehicle responded as intended. The contact stated that the failure had been recurring while parking the vehicle on an incline, requiring the electric parking brake to be engaged. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact related the failure to NHTSA Campaign Number: 18V141000 (Electrical System, Power Train); however, the VIN was not included. The manufacturer was notified of the failure and informed the contact that the VIN was not associated with a recall due to the manufacturing date of the vehicle. The failure mileage was approximately 50,000.

The dealer was unable to diagnose the vehicle because the message was no longer displayed. The vehicle was not repaired. The contact stated that the failure reoccurred, and the vehicle was returned to the same dealer. The dealer was unable to diagnose the vehicle or duplicate the failure. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was approximately 85,000.

After exiting thruway after driving 10-15 minutes, car shuts off at a stop sign/traffic light. notice on screen right hand side state transmission not in park. I put car into park then restart vehicle. This has happened three times in last 6 months. Taken to dealer and they cannot reproduce problem or when scanned, no problem shows up.
