Recall 12V308 affects 1,174 2012 Mack Granite (Gu), Pinnacle (Chu), and Pinnacle (Cxu) trucks for loose wiper-linkage hardware. Free repair at a franchised Mack dealer.
Mack is recalling 1,174 2012 Granite (Gu), Pinnacle (Chu), and Pinnacle (Cxu) trucks because loose windshield wiper linkage hardware can detach from the wiper motor. If the wipers stop working, driver visibility is reduced in certain driving conditions, increasing crash risk; the Mack dealer repair will be free once available.

What's wrong?
The windshield wiper linkage on the 2012 Mack Granite (Gu), Pinnacle (Chu), and Pinnacle (Cxu) is the mechanical arm assembly between the wiper motor and the wiper arms. When the driver turns the wipers on, the motor moves the linkage back and forth, and the linkage moves the wiper blades across the windshield. That motion keeps the driver’s view clear in rain or road spray.
On affected Mack trucks, the hardware that holds the linkage to the wiper motor was not tightened enough. If that hardware loosens, the linkage detaches from the motor. The motor still has power, but its motion no longer reaches the wiper arms, so the windshield wipers stop working.
There is no warning sign before failure. The wipers can work normally until the linkage separates, then stop without giving the driver advance notice.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Reduced driver visibility can make it harder to see traffic, road hazards, and lane position, increasing the risk of a crash. Schedule the recall repair soon and use extra care if visibility feels limited. Repair will be free at any franchised Mack dealer once available.
What should I do?
- Check your VIN to confirm your 2012 Mack Granite (Gu), Pinnacle (Chu), or Pinnacle (Cxu) is included in this recall.
- Contact a franchised Mack dealer and ask whether the hardware replacement for the windshield-wiper linkage is open for your VIN.
- Reference recall number 12V308 when you call.
- Bring the recall notice if Mack mailed one, plus any service records for the windshield wipers.
- Avoid driving in rain or low-visibility conditions until the wiper-linkage hardware is secured.
What happens at the repair
At the dealer, a Mack technician replaces the hardware that secures the windshield wiper linkage to the wiper motor. That hardware keeps the linkage attached so the wipers move across the windshield. The dealer repair will be free once available, with parts and labor covered under the recall. Ask the service desk to confirm the repair is tied to campaign 12V308 before work begins.
