The problem
Mack Trucks, Inc. (Mack) is recalling certain 2027 Anthem AN (4) and Pioneer PR (4) vehicles. The center roof marker lights may fail to illuminate. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
The risk
Marker lights that fail to illuminate can reduce visibility, increasing the risk of a crash.
The fix
Dealers will replace the center roof marker light, free of charge. Interim letters notifying owners of the safety risk were mailed September 22, 2026. Additional letters will be sent once the final remedy is available. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0498. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning August 13, 2026.
