2010 Mack Leu recalls 6
Recall repairs are free. Your dealer fixes them whether or not you bought the car there - check your VIN at nhtsa.gov/recalls to see if yours is done. What to do
- The problem
- Mack Trucks, Inc. (Mack) is recalling certain model year 2010-2015 LEU vehicles manufactured May 14, 2009, through February 14, 2014, and equipped with a Cummins ISL engine. In the affected vehicles, the exhaust pipe may disconnect from the muffler/catalyst.
- The risk
- If the exhaust pipe separates from the muffler on a twin-steer configured vehicle where the vehicle is operated from the right side, the operator may be exposed to carbon monoxide levels which may cause personal injury.
- The fix
- Mack will notify owners. The recall began on April 21, 2014. The recall is expected to begin in late April 2014. Owners may contact Mack Trucks at 1-336-393-2000. Mack's number for this recall is SC0376.

On these vehicles the alternator ground cable runs directly to the starter, which defeats the circuit protection.
- The risk
- In the event of an electrical short, a vehicle fire may result.
- The fix
