Recall 14V208 affects 44,047 2007-2014 Mack trucks with hazard warning lights that can fail. Repair is free at any franchised Mack dealer.

Mack is recalling 44,047 2007-2014 trucks, including Leu, Granite (Gu), and Mru models, because the Hamsar electronic flasher can stop the hazard warning lights from working. Failed hazard lights reduce visibility and increase crash risk; the Mack dealer repair will be free once available.

What's wrong?

The Hamsar Electronic Flasher on these 2007-2014 Mack trucks is the electrical unit that makes the hazard warning lights flash in a steady pattern. It switches power to the exterior lamps so other drivers can see a stopped or disabled truck. The recall covers Mack Leu, Granite (Gu), Mru, Pinnacle (Cxu), Gu, Chu, Pinnacle (Chu), Cv, Td, Cxu, and Ct models equipped with that flasher.

On affected trucks, the flasher unit can fail to operate the hazard warning lights. When that happens, the truck loses the flashing hazard signal that warns traffic around it during a breakdown, roadside stop, or low-speed emergency. The filing does not identify a separate owner-serviceable part behind the failure; the recalled part is the flasher unit itself.

There is no warning sign before failure. An owner or driver would notice the problem only when the hazard switch is used and the exterior hazard lamps do not flash as expected.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.

What's the safety risk?

If the hazard warning lights fail, other drivers have less warning that the truck is stopped or disabled, which increases crash risk. Use extra caution if the truck has to stop on the road, and contact a dealer for repair status. Repair will be free at any franchised Mack dealer once available.

What should I do?

  1. Check your VIN to confirm your 2007-2014 Mack Leu, Granite (Gu), Mru, Pinnacle (Cxu), Gu, Chu, Pinnacle (Chu), Cv, Td, Cxu, or Ct truck is included in this recall.
  2. Contact a franchised Mack dealer to schedule the free electronic flasher unit replacement that fixes the hazard warning light failure.
  3. Bring the recall notice if Mack mailed one. If not, reference recall number 14V208 when you call.
  4. Drive with extra care until the repair is complete, especially when stopped or operating in low-visibility conditions.
  5. Call Mack customer service at 1-866-298-6586 with questions about scheduling or dealer handling.

What happens at the repair

At the dealer, a Mack technician replaces the Hamsar electronic flasher unit that controls the hazard warning lights. The filing says the replacement is free of charge. Because the remedy status for this page is not marked available, treat the dealer process as confirmed repair guidance, not a scheduling promise from this article. Once the repair is open for your VIN, parts and labor are covered under recall 14V208.

What should I do if my 2007-2014 Mack truck is on this recall?

Check your VIN to confirm your specific truck is included in recall 14V208. If it is, contact a franchised Mack dealer to schedule replacement of the electronic flasher unit. Reference recall number 14V208 and Mack recall number SC0379 when you call.

Is the recall repair free?
