What's wrong?
The alternator cable on the 2011 Western Star 4900, Coronado, and Cascadia heavy trucks carries electrical current from the alternator to the truck's charging system. The alternator keeps the batteries charged and supplies power for electrical loads while the engine is running. The cable insulation is supposed to keep that current contained and protected from nearby engine parts.
On affected trucks, the alternator cable is routed or secured too close to an engine heat shield. The cable can touch the shield, or sit close enough that heat and vibration damage the insulation. Once the insulation is damaged, the cable is no longer properly protected in that area.
There is no warning sign before failure. An owner or technician will need to inspect the cable routing and insulation condition to confirm whether the problem is present.
Who's affected?
The 4900, Coronado, and Cascadia share the same alternator, generator, and regulator component in this recall.

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?
Damaged insulation on the positive alternator cable can let the cable contact grounded metal. That can create a short circuit and start a fire. If your VIN is included, arrange the recall inspection and cable routing repair promptly. Repair will be free at any franchised Western Star dealer once available.
What should I do?
- Check your VIN to confirm your 2011 Western Star 4900, Coronado, or Cascadia heavy truck is included in this recall.
- Watch for the owner notice from Daimler Trucks if you have not received it.
- Contact a franchised Western Star dealer and ask whether the alternator-cable inspection and routing repair is open for your VIN.
- Reference recall number 11V110 when you call the dealer.
- Avoid operating the truck if you see damaged alternator-cable insulation or signs of electrical heat, and ask the dealer for transport guidance.
What happens at the repair
At the dealer, a Western Star technician inspects the alternator cables for damaged insulation. If damage is found, the damaged cable is replaced. The technician also changes the cable routing and securement so the alternator cable has enough clearance from the engine heat shield. The dealer repair will be free once available, with parts and labor covered under recall 11V110.
