Service bulletin L-TT-0146-13

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.

NHTSA componentPARKING BRAKE; BACK OVER PREVENTION

NHTSA's summary

The ?13-?14MY GS 350 comes equipped with an electronic Rear Parking Brake. The adjustment method is different from the previous generation GS model which had a mechanical parking brake. Because of this, a different procedure is required when performing adjustments. If the incorrect adjustment procedure is performed, this may adversely affect the performance of the parking brake including possibility of causing a noise when the vehicle travels over bumps (i.e. rattle).
