What's wrong?
The electrical circuitry on 2008-2012 Mack Leu and Mru heavy trucks carries power to truck systems and protects those circuits when current rises too high. Circuit protection, such as a fuse or breaker, is the electrical equivalent of a pressure relief point. It is supposed to interrupt or limit excess current before wiring and connected components are overloaded.
On these trucks, the circuitry was built without adequate overcurrent protection. If a circuit draws more current than it should, the protection built into the system does not give the wiring enough margin. That leaves the circuit exposed to overload instead of stopping the problem at the protection point.
There is no warning sign before failure. An owner or driver should not count on a light, noise, smell, or change in how the truck runs before the electrical issue appears.
Who's affected?
The same electrical-system component appears across both Leu and Mru model lines from 2008-2012.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific truck.
What's the safety risk?
An electrical overage can let too much current reach the mirror switch circuit. The fuse meant to stop that current can fail, which lets the mirror switch overheat. An overheated switch increases the risk of a vehicle fire. Schedule the recall repair soon and ask the dealer whether the inspection includes switch replacement. Repair will be free at any franchised Mack dealer once available.
What should I do?
- Check your VIN to confirm your 2008-2012 Mack Leu or Mru is included in this recall.
- Contact a franchised Mack dealer to schedule the free relay-harness installation and mirror-switch inspection.
- Bring the recall notice if Mack mailed one. If not, reference recall number 11V212 when you call.
- Ask the dealer to replace the mirror switch if the inspection shows overheating.
- Park the truck away from structures until the relay harness is installed if you notice heat, odor, or damage near the mirror switch.
What happens at the repair
Mack's remedy calls for a Mack technician to install a relay harness so the mirror switch circuit has protection against overheating. The technician also inspects the mirror switch. If the switch shows heat damage, the dealer replaces it. The dealer repair will be free once available, including the inspection, harness installation, and switch replacement when needed. Ask the service desk to confirm the remedy status before bringing the truck in.

Frequently asked questions
What is recall 11V212?
Recall 11V212 covers 3,763 2008-2012 Mack Leu and Mru heavy trucks with electrical circuitry that lacks adequate overcurrent protection. In an electrical overage, the mirror switch circuit can overheat and raise fire risk. Mack dealers install a relay harness, inspect the mirror switch, and replace it if needed for free.
What should I do if my 2008-2012 Mack Leu or Mru is on this recall?
Check your VIN to confirm your specific truck is included in recall 11V212. If it is, contact a franchised Mack dealer to schedule the relay harness installation and mirror switch inspection. Reference recall number 11V212 when you call. The inspection and repair are free.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to repair safety defects at no cost, and Mack's remedy says all inspections and repairs are free. The dealer installs a relay harness, checks the mirror switch for overheating, and replaces the switch if needed.
What is the safety risk in recall 11V212?
The safety risk is fire from an overheated mirror switch circuit. Recall 11V212 says the fuse that should stop excess current from reaching the mirror switch circuit can fail during an electrical overage. Mack's repair adds a relay harness to prevent overheating.
What if I bought my Mack Leu or Mru used?
The free recall repair still applies. Federal recall law follows the vehicle, not the first owner. Check your VIN to confirm whether your truck is included, then contact a franchised Mack dealer or Mack customer service at 1-800-866-1177 with recall number 11V212.
