Good news: Recall repairs cost you nothing. Book with any manufacturer dealer and quote the recall number — they are required to do the work free of charge, with no time limit and regardless of how many owners the car has had.

Transport Canada lists: Anthem 2026–2027 · Granite 2026–2027 · Pinnacle 2027 · Pioneer 2026

What is wrong

Why it matters

A wheel separation could cause a loss of control and increase the risk of a crash. Additionally, a wheel that separates could create a road hazard for others.

What the dealer will do

To reduce the safety risk, Mack advises you not to drive your truck until the recall repairs have been completed. Mack will notify owners by mail and advise you to contact a dealership to arrange for an inspection of the wheels and hubs. Any damaged parts will be replaced.

23 April 2026

Transport Canada lists: Anthem 2026–2027 · Pioneer 2026–2027

What is wrong

Why it matters

A loss of ABS and ESC could increase the risk of a crash.

What the dealer will do

Mack will notify owners by mail and advise you to take your truck to a dealership to inspect and, if necessary, replace the rear brake modulator(s). The dealer will also install a cover on the connector(s).

Transport Canada recall 2026154 · manufacturer campaign SC0493

1 April 2026

Transport Canada lists: Anthem 2027 · Pioneer 2026–2027

What is wrong

On certain trucks, a software problem could cause the trailer turn signal lights not to work when towing. Note: This problem would cause an error message to display on the instrument panel.

Why it matters

Turn signals that don't work may cause a person not to recognize when a driver intends to turn or change lanes and could increase the risk of a crash.

What the dealer will do

To reduce the safety risk, Mack advises you to test the trailer turn signals before driving, until the recall repairs are completed. Mack will notify owners by mail and advise you to take your truck to a dealership to update the vehicle software.

What the dealer will do

Mack will notify owners by mail and advise you to take your truck to a dealership to replace the load lock clamps.

Transport Canada recall 2025640 · manufacturer campaign SC0488

20 November 2025

What is wrong

On certain trucks, the automatic high beams may not switch to low beams automatically. As a result, the trucks may not meet certain requirements of Canadian regulations.

Why it matters

High beams that stay on could cause glare for oncoming drivers and increase the risk of a crash.

What the dealer will do

To reduce the safety risk, Mack recommends you switch manually between the low beams and high beams until the recall repairs have been completed. Mack will notify owners by mail and advise you to take your vehicle to a dealership to update the vehicle software.
