What's wrong?
The turbocharger oil supply line on 2010-2016 Mack Granite (Gu), Terrapro (Leu/Mru), and Lr trucks carries engine oil to the turbocharger. The turbocharger uses exhaust energy to push more air into the engine, and the oil line keeps its moving parts lubricated and cooled while the engine is running.
On affected trucks with certain Cummins Westport ISL G engines, that oil supply line sits too close to nearby air and fuel control parts. Variation in the clean air piping, the oil line, or the air fuel control tube leaves the line able to touch the turbocharger inlet elbow, the clean air intake clamp, or the air fuel control tube. That contact wears or damages the line and lets engine oil leak.
An owner or technician can see damage to the turbocharger oil supply line during inspection. Oil around the line or nearby turbocharger area is the warning sign before the leak becomes worse.

What's the safety risk?
Oil leaking from the turbocharger oil supply line near the engine exhaust manifold increases the risk of a fire. Damage to the line or visible oil leakage is the warning sign to take seriously. Schedule the inspection and repair promptly, and stop using the vehicle if you see oil near the line. Repair is free at any franchised Mack dealer.
What should I do?
- Check your VIN to confirm your 2010-2016 Mack Granite (Gu), Terrapro (Leu/Mru), or Lr truck is included in this recall.
- Contact a franchised Mack dealer to schedule the free turbocharger oil supply line inspection and repair.
- Tell the dealer this is recall number 15V702, and ask whether the line needs interference removed or replacement because an oil leak near the exhaust manifold raises fire risk.
- Bring the recall notice if Mack or Cummins mailed one, or give the dealer recall number 15V702 when you schedule.
- Watch for oil smell, oil leaks, or smoke around the engine area until the repair is complete.
What happens at the repair
At the dealer, a Mack technician inspects the turbocharger oil supply line for interference or damage near the turbocharger inlet elbow, clean air intake clamp, and air fuel control tube. The technician removes the interference and replaces the oil supply line when damage is found. The recall repair is free, with parts and labor covered. If you already paid for this repair on a truck not covered by Mack's limited warranty, Mack's reimbursement plan covers eligible expenses. Bring repair receipts and service paperwork to the dealer.
