02 / Official safety campaigns

5 recall campaigns on file.

A campaign can cover only certain production dates or configurations. The count does not tell you whether an individual car has an open recall.

Dec 9, 2020 Safety recallEQUIPMENTCampaign 20E090000

Reported concern

Icon Vehicle Dynamics, LLC (Icon) is recalling all 05-UP FSD 2.5 Centerline Stabilizer Kits with part number 65050. The kits were sold as an accessory for certain 2005-2021 Ford F-250 4X4 and F-350 4X4 pickup trucks. The foam ring inside the stabilizer "through shaft" may block the piston ports, possibly causing the steering to lock up.

Manufacturer’s stated response

Icon will notify owners, and dealers will install a new shock assembly with a revised foam ring and steel support disc, free of charge. The recall began December 21, 2020. Owners may contact Icon customer service at 1-951-689-4266.
