2024 Mack LR: Electrical System recall

NHTSA campaign 23V310000 · 5 units potentially affected · filed May 2, 2023

What's wrong

Mack Trucks, Inc. (Mack) is recalling certain 2024 LR electric garbage trucks, equipped with electric horns. The circuit connecting the horn button to the horn is missing, making the horn inoperative.

Why it matters

A vehicle with an inoperative horn cannot alert other drivers, increasing the risk of a crash.

The fix

Dealers will add the necessary circuits to connect the horn button to the horn, free of charge. Owner notification letters were mailed June 20, 2023. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC443.

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
