Service bulletin TI-81-12

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

122-Y6Q8V-062017-08-01. Service bulletin. Concern: Power steering lines may be leaking at the power steering rack. Work Procedure: The power steering lines at the steering rack may leak due to a damaged o-ring(s). The o-ring damage results from an imperfection in the line. Replacing the o-rings alone is not sufficient to repair the concern; the line must be replaced as well. Note however that it is not necessary to replace the steering rack.
