Revision 2 January 2021

Dealer Service Instructions for:

Safety Recall W81 / NHTSA 20V-657 Front Lower Control Arm

 

Revised with new parts ordering information.

 

Remedy Available

2021 (KL) Jeep Cherokee

 

NOTE:  This recall applies only to the above Latitude and Limited vehicles equipped with Normal Duty Suspension (sales code SDA).

 

NOTE:  Some vehicles above may have been identified as not involved in this recall and therefore have been excluded from this recall.

 

IMPORTANT:  Some of the involved vehicles may be in dealer new vehicle inventory.  Federal law requires you to complete this recall service on these vehicles before retail delivery.  Dealers should also consider this requirement to apply to used vehicle inventory and should perform this recall on vehicles in for service.  Involved vehicles can be determined by using the VIP inquiry process.

 

Subject

About 700 of the above vehicles may have been built with one or both lower control arms with hardness below specification. A front lower control arm manufactured with hardness below specification may result in a fracture while driving that may result in a loss of steering control, which can cause a crash without prior warning.

 

Repair

Inspect both front lower control arms and replace as needed. FCA US recommends that owners do not drive their vehicles until they receive instructions on how to have this inspected and repaired, if necessary. Mobile Repair should be utilized for the inspection, if available.

 

Alternate Transportation

Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if inspection determines that front lower control arm replacement is required and the vehicle must be held overnight.
