Fix Dealers will update the turn signal indicator software, free of charge. Owner notification letters were mailed May 7, 2026. Owners may contact Mack's customer service at 1-800-866-1177.

Two numbers, one recall

Every safety recall carries two identifiers. SC0493 is the number Mack assigned in its own system: it is what appears on the owner letter, on the dealer’s service screen and on the repair order. 26V207000 is the number NHTSA filed the same recall under when the manufacturer reported it, and it is the one every federal record, this site included, is keyed on.

The repair is free by federal law for vehicles up to fifteen years old. Whether one particular vehicle is included is settled by its VIN against the manufacturer’s build list, not by its model year.
