## What the record says

- **Product**: MACK PIONEER PR (4) (2025) - Recall 25V803000
- **Reason**: 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." High beam headlights that do not switch to low beam as intended can reduce visibility for oncoming traffic, increasing the risk of a crash.
- **Classification**: Not supplied
- **Recalling firm**: Mack Trucks, Inc.
- **Quantity**: 247
- **Agency-reported status**: Published safety recall
- **Source record identifier**: 306407
