Mack Recall Fix On The Way for 3,096 Trucks

Mack Recalls 3,096 Trucks Over Parts That May Fall Off

A new Mack recall affects 3,096 Anthem and Pioneer trucks because parts of the front grille and air intake may come loose while driving. These parts could fall onto the road and create a hazard for other vehicles. The recall covers certain trucks from the 2025 through 2027 model years.

The recall follows 243 warranty claims and 95 field reports linked to the problem. However, Mack has not reported any crashes or injuries related to the defect.

Which Trucks Are Included in the Mack Recall?

The Mack recall affects two truck models. Most of the recalled vehicles are newer Mack Pioneers.

The affected trucks include:

• Mack Pioneer PR (4): 2,868 trucks from model years 2025–2027.

• Mack Anthem AN (4): 228 trucks from model years 2026–2027.

The affected Pioneer trucks were built between October 22, 2024, and September 18, 2026. The affected Anthem trucks were built between July 2, 2025, and February 13, 2026.

Not every truck from these model years is included. Owners and fleet managers can check individual vehicle identification numbers (VINs) to confirm whether a truck is affected.

Mack estimates that about 6.1% of the recalled trucks may have the defect. Still, all 3,096 vehicles are included in the recall.

What Is Causing Parts to Come Loose?

The problem involves trim pieces called bezels. These parts sit around the upper air intake and front grille.

According to Mack’s report to the National Highway Traffic Safety Administration (NHTSA), some bezels may not fit tightly against the truck’s mounting surfaces.

The parts are held in place by clips. However, fitment problems during assembly may prevent the clips from locking into place as intended.

Over time, these parts could loosen or fall off while the truck is moving.

A detached bezel could land on the roadway and create a danger for nearby vehicles. Other drivers could strike the loose part or take sudden action to avoid it.

Mack says the problem raises the risk of a crash or injury. The Mack recall does not involve a reported defect in the trucks’ steering, braking, or engines.

What Mack Truck Drivers May Notice

Mack’s report describes a possible sign that a bezel is not properly secured.

A loose clip may cause a slightly larger gap along the outer edge of the trim piece. This gap may be visible during an inspection.

For commercial truck drivers, this information could be useful during normal pre-trip inspections. A loose or uneven piece of exterior trim may need closer attention.

Drivers who notice a problem can report it to their maintenance department or contact an authorized Mack dealer.

The Mack recall does not include an instruction requiring all affected trucks to be parked. However, the loose parts could create a safety hazard if they detach during travel.

Mack Recall Follows 243 Warranty Claims

The recall documents provide details about how the problem developed.

Mack reported 243 warranty claims and 95 field reports related to the issue. The company reported no crashes or injuries linked to the defect.

Warranty records date back to August 2025. Claims increased during 2026 and reached 42 in July.

Mack opened a safety investigation on March 18, 2026. A safety review took place the following day, and another committee requested more information on March 25.

The company continued reviewing the issue over the following months.

On September 14, a second safety review called for further action. Mack’s safety committee then determined on September 24 that the problem was a safety defect requiring a recall.

The company submitted its official recall report to NHTSA on October 1, 2026.

The documents do not state that each warranty claim involved a separate truck. They also do not say how many parts actually fell off while vehicles were moving.

How Mack Plans to Repair the Affected Trucks

Mack dealers will inspect and repair affected vehicles free of charge.

The repairs involve changes to the intake and grille bezels.

For the air intake, dealers will replace affected bezels with updated parts. These newer parts have improved clearance around the mounting clips to help them fit correctly.

For the grille, technicians will add holes and install cable ties to provide extra support. The ties are designed to help keep the bezels attached if the original clips do not hold as intended.

Mack introduced updated intake bezel parts into production in February 2026.

The company also reported placing trucks still at its factory on a stop-shipment hold. Those vehicles will not be released until the grille bezel problem is corrected.

The Mack recall documents do not provide an estimated repair time or say how long a truck may need to remain at a dealership.

How to Check the Mack Recall by VIN

Mack scheduled affected VINs to become searchable through NHTSA on October 8, 2026.

Owner notification letters are expected to be mailed November 30, 2026.

Truck owners and fleet managers can check for recalls using the official NHTSA recall lookup or the Mack Trucks recall website.

The recall information includes:

• NHTSA campaign number: 26V631000

• Mack recall number: SC0501

• Mack customer service: 1-800-866-1177

• Expected owner notification date: November 30, 2026

Owners can also contact an authorized Mack dealer for more information about inspections, repairs, and service scheduling.

What the Mack Recall Means for Drivers and Fleets

For drivers operating affected Mack trucks, the main concern is the chance that exterior parts could come loose on the road.

The recall also creates a maintenance issue for trucking companies and owner-operators. Trucks covered by the recall will need to be checked and repaired, which may require time away from regular freight operations.

Although Mack will provide the repairs free of charge, the documents do not say whether owners will face downtime or other operating costs.

Fleet maintenance departments may also need to check multiple VINs and arrange repairs for affected equipment.

The recall covers relatively new trucks, including vehicles from the 2027 model year. Mack has identified changes intended to keep the affected parts securely attached.

No crashes or injuries have been reported, but the company is recalling the trucks because detached components could create a hazard for other road users.

For affected drivers and fleets, confirming recall status and arranging the required repairs will be the next steps.
