Recalls (6)

SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:HOSES, LINES/PIPING, AND FITTINGS04/06/2019

Braun Corporation (Braun) is recalling certain 2014-2019 Toyota Sienna mobility van conversions. The brake lines may have incorrect tube nut fittings installed, which may cause a pressure drop within the braking system.

Risk: The reduction in the braking system pressure may cause a loss of braking power in the rear braking system, increasing the risk of crash.

Fix: Braun has notified owners, and dealers will install an adaptor to correct the issue, free of charge. The recall began June 25, 2019. Owners may contact Braun customer service at 1-800-488-0359.
