Service bulletins for the 2018 Subaru Crosstrek

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.

This Bulletin provides information regarding Event Data Recorder (EDR) functionality which has been incorporated into the airbag system. The function of the EDR is best explained using the following statements found in the vehicle Owner?s Manual: ?This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR is to record, in certain crash or near crash-like situations such as an airbag deployment or hitting a road obstacle, data that will assist in the understanding how a vehicle?s systems performed. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as: ? How various systems in your vehicle were operating; ? Whether or not the driver and passenger safety belts were buckled/fastened; ? How far (if at all) the driver was depressing the accelerator and/or brake pedal; ? How fast the vehicle was traveling. This data can help provide a better understanding of the circumstances in which crashes and injuries occur.

Their color formulations are updated on a continual basis. Some vendors may have different color names than those provided to them by SOA. Be sure to double-check the codes and formulas beforehand to help insure an accurate color match. Should discrepancies arise, please refer your Body Shop contact inquiries to the specific paint vendor or their jobber / supplier for the most updated formula information. The paint coding information can be found on the vehicle's VIN plate.
