Safety Recall 23S32
Certain 2023 Model Year Nautilus Vehicles
Rear Shock Absorber Jounce Bumper Inspection

 

AFFECTED VEHICLES

Vehicle Model Year Assembly Plant Build Dates
Nautilus2023OakvilleFebruary 20, 2023 through March 9, 2023

US population of affected vehicles: 366. Affected vehicles are identified in OASIS and FSA VIN Lists.

 

REASON FOR THIS SAFETY RECALL

In some of the affected vehicles, a rear shock, with a defective rod stopper crimp, may have been installed on the vehicle. The shock may be over-extended in certain driving conditions which may result in damage to the brake hose, rear axle half shaft, wheel speed sensor and stabilizer bar link. The driver could experience extended stopping distance if unintended stresses on the brake hose progressed to a damaged/leaking brake hose, which can increase the risk of a crash.

 

SERVICE ACTION

DO NOT DEMONSTRATE OR DELIVER any new in-stock vehicles involved in this safety recall. A complete Dealer Bulletin will be provided to dealers 3rd Quarter 2023, when it is anticipated that parts ordering information and repair instructions will be available to support this safety recall.

IMPORTANT: Dealers should open a Repair Order (RO) only when a full dealer bulletin is published. Opening an RO against an Awareness or Advance Notice will result in warranty rejections against a recall.

 

CUSTOMER NOTIFICATION

Owners of record will be notified via first-class mail after repair instructions and parts ordering information have been provided to dealers.

PLEASE NOTE:

Federal law requires dealers to complete this recall service before a new vehicle is delivered to the buyer or lessee. Violation of this requirement by a dealer could result in a civil penalty of up to $26,315 per vehicle. Correct all vehicles in your new vehicle inventory prior to delivery.

 

DEALER-OPERATED RENTAL VEHICLES

The Fixing America’s Surface Transportation (FAST) Act law effective June 2016 prohibits a rental company from selling, renting, or leasing vehicles subject to a safety or compliance recall. Please consult your legal counsel for legal advice.

FSA 23S32 – Certain 2023 model year LincolneBay logo Nautilus vehicles – Defective rear Continuous
Controlled Damping (CCD) shock crimp

Chronology

On March 7, 2023, the Ford Oakville Assembly Complex (OAC) Tire & Wheel install area identified an over-extended condition on rear Continuous Controlled Damping (CCD) shock absorbers. Visual checks confirmed that the rear shocks were over-extending up to 27 mm.

OAC identified a similar condition on the front shocks on March 8, 2023. All front CCD shocks go through a Spring Module sub-assembly where a load of approximately 3KN in the process will reveal the overextended condition, which is detectable by the operator, preventing the shocks from being installed into a vehicle. Rear CCD shocks do not go through this process.

On March 9, 2023, Ford’s Critical Concern Review Group (CCRG) approved a stop ship for Nautilus vehicles equipped with CCD shocks.  Vehicles at the plant were inspected for this condition and repaired accordingly.  Of the 90 vehicles inspected, 72 right rear shocks and 21 left rear shocks were identified with this concern.  Based upon this data, it was determined that rear shocks with this condition could be assembled into a vehicle without detection by the operator.  All inventory of the suspect shocks were quarantined.

On March 14, 2023, the issue was reviewed by Ford’s CCRG. The CCRG investigation identified an insufficient crimping operation in the shock assembly at the supplier facility.  Supplier production data review by the CCRG revealed that the issue may have existed and gone undetected from February 14, 2023 through Mar 10, 2023 when additional load capability verification was established.  Tooling replacement & 100% detection was restored for parts produced on Mar 11, 2023.

From April through May 2023, the Underbody Systems engineering team evaluated the effect on vehicle components if an over extended rear shock condition is present.  The analysis included review of Design Failure Mode Effects Analysis (DFMEA) control documents along with analysis of technical drawings.  The CCRG determined that an over extension of the rear shock during assembly into vehicle or during certain vehicle driving conditions may damage the brake hose along with other suspension components.

Ford is not aware of any warranty, field reports, or customer complaints related to this condition

Ford is not aware of any accidents or injury related to this condition.

On June 16, 2023, Ford’s Field Review Committee reviewed the concern and approved a field action.
