MACK TRUCKS CMH TRIDENT, CMM GRANITE (2016–2019)
What the hazard is
If the service brake relay valve melts, there may be increased stopping distance when the brakes are applied, increasing the risk of an accident or injury to vehicle occupants and other road users.
What to do
Affected owners will be contacted in writing and advised to contact their nearest Volvo Group Australia repairing dealer to replace the exhaust outlet pipe and replace the relay valve, where required. For more information, owners can contact their nearest authorised Volvo Group Australia repairing dealer on 07 3718 3500 or via email vga.warranty@volvo.com
Defect
The outlet exhaust pipe is incorrectly positioned, which may cause heat damage to some braking system components, such as the service brake relay valve, which may melt.
