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.

Owners of these vehicles have filed 555 complaints in the brakes category.
