## What is wrong

Mack Trucks, Inc. \(Mack\) is recalling certain 2026 Anthem \(4\) and 2025\-2026 Pioneer vehicles. The automatic high beams \(AHB\) may not switch to low beam headlights as intended.  As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."


## What can happen

High beam headlights that do not switch to low beam as intended can reduce visibility for oncoming traffic, increasing the risk of a crash.


## The remedy

As an interim action, Mack will update the vehicle software through an over\-the\-air \(OTA\) update to disable the AHB feature, free of charge. Owner letters were mailed May 29, 2026. Owners may contact Mack's customer service at 1\-800\-866\-1177. Mack's number for this recall is SC0488. Vehicle Identification Numbers \(VINs\) involved in this recall will be searchable on NHTSA.gov beginning November 27, 2025.
