Plain-English summary

Syncro Corporation is recalling certain Hayes Sway Master aftermarket sway control products, part number 81775. The recall affects 1,944 units.

These units may conflict with the tow vehicle's factory-installed integrated brake controllers, which can disable the tow vehicle's ability to apply the trailer brakes. If the trailer brakes cannot be applied, it can cause a loss of control, increasing the risk of a crash.

Syncro will notify owners and instruct them to return the unit for repair, free of charge. The recall began on August 16, 2018. Owners may contact Hayes Customer Service at 1-800-882-1204 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
