EXTERIOR LIGHTING:TURN SIGNAL
- The defect
- Mack Trucks, Inc. (Mack) is recalling certain 2025-2027 Pioneer (4) and 2027 Anthem (4) trailers. The trailer turn signals may not function properly. 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 it can cause
- Turn signals that do not function properly may fail to indicate the driver's intention to change vehicle direction, increasing the risk of a crash.
- What the dealer does
- Dealers will update the turn signal indicator software, free of charge. Owner notification letters were mailed May 7, 2026. Owners may contact Mack's customer service at 1-800-866-1177. Mack's number for this recall is SC0493. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov April 1, 2026.
The repair is free, whatever the age or mileage of the vehicle, and whether or not you are the original owner.
Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .

How this campaign compares
At 86 vehicles this is a small campaign: 72% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published are as large or larger. The middle campaign on file covers 472. It covers model years 2025 to 2027, so the oldest vehicles on it were one model year old when the defect was reported to NHTSA.
Mack vehicles have been recalled over the exterior lighting 15 times before this, most recently in November 2025 as 25V803000. That is not evidence the earlier repair failed.
The vehicles on this campaign carry 7 other recalls published here, the newest being: 26V515000 (exterior lighting), 26V351000 (wheels), 26V261000 (service brakes, air), 25V803000 (exterior lighting).
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
