2021 Mack LR Electric: Electrical System recall

NHTSA campaign 22V706000 · 1 units potentially affected · filed Sep 21, 2022

What's wrong

Mack Trucks, Inc. (Mack) is recalling one 2021 truck. The coolant line in the high voltage battery pack may not be fully seated and locked, which can result in the loss of coolant and an electrical short circuit.

Why it matters

A battery short circuit increases the risk of a fire.

The fix

Mack will inspect the battery packs, and replace them as necessary, free of charge. The affected vehicle was within the manufacturer's control, has been repaired, and therefore no owner letters were mailed. Owners may contact Mack's customer service at 1-800-866-1177.

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.
