Mack has issued two precautionary recall notices, one for around 7,668 Metro-Liner, Trident, Titan, Granite and Super-Liner model trucks sold in Australia over the past 11 years and another for 463 Macks for a separate issue.

The larger of the two recalls according to VGA spokesman Tom Chapman relates to a software system check to ensure that the air system warning is set to the correct level and affects trucks sold between December 31, 2006 and October 17, 2016.

“The recall involves trucks being brought to a Mack dealer and being plugged in to ensure the warning is set to the correct level and alerts the driver, it is a precautionary recall that we initiated and has not caused any incidents,” said Tom Chapman.

He went on to say that the earlier smaller recall was again a precautionary one, which was initiated by Mack to ensure that the correct torque setting had been applied to front brake mounting hardware during manufacture.

Chapman told T&B News that while the company was confident that the correct settings were applied, the fact that it could not guarantee the correct torque had been applied triggered the recall.

“We always play it safe and when our checks uncover situations like this we always err on the side of caution,” he said.

The smaller of the two recalls involves Metro-Liner, Granite, Trident, Titan and Super-Liner truck models..

Owners will be contacted by VGA but are advised to contact an authorised dealership to arrange to arrange an inspection and any rectification.
