Service bulletin SB-26-33-001

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's summary

On certain Model 3 vehicles, brake lines may be corroded beyond acceptable limits, which may result in loss of brake fluid. Loss of brake fluid will result in a customer facing alert if the fluid reaches the predetermined level to trigger an alert. Upon customer complaint of a low brake fluid alert, evidence of a brake fluid leak, or a failed periodic roadworthiness inspection, inspect the brake lines. If corrosion is found on any of the brake lines, replace all brake lines on the vehicle with new corrosion-resistant parts, in one combined repair. NOTE: Due to dual reduncancy, vehicle safety is not impacted by corrosion on the brake lines.
