Recall 11V177 affects 358 2011 Ud UD1800, UD2000, UD2300, UD2600, and UD3300 trucks for unsecured headlamp adjustment. Repair is free at any franchised Ud dealer.
Ud is recalling 358 2011 UD3300, UD2600, UD2000, UD1800, and UD2300 medium duty trucks because the headlamps and low beam horizontal adjustment mechanism were not secured against adjustment after manufacture. Poorly aimed headlamps can leave the road surface underlit or make the truck harder for other motorists to see, increasing crash risk; the Ud dealer repair will be free once available.

What's wrong?
The headlamps on the 2011 Ud UD3300, UD2600, UD2000, UD1800, and UD2300 are meant to aim the low beams in a fixed direction after the truck is built. The optical aiming setup lets the factory set the lamp position so the road is lit without sending the beam too high or too far to one side.
On these trucks, the visual optical aiming headlamps and the low beam horizontal adjustment mechanism were not secured well enough after manufacture. That means the low beam aim can move out of its factory-set position. If the aim shifts, the truck no longer matches the lighting standard for headlamps, reflective devices, and related equipment.
There is no warning sign before failure. The driver should not expect a dashboard alert or obvious part noise from this defect, because the problem is with how the headlamp adjustment is held in place.
Who's affected?
Covers five 2011 Ud truck models, all tied to the same headlight component.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether this recall applies to your specific truck.
What's the safety risk?
Improper headlamp adjustment can leave the road surface underlit or make the truck harder for other motorists to see, increasing crash risk. Drive cautiously at night and schedule the recall repair soon. Repair will be free at any franchised Ud dealer once available.
What should I do?
- Check your VIN to confirm your 2011 Ud UD3300, UD2600, UD2000, UD1800, or UD2300 is included in this recall.
- Contact a franchised Ud dealer to confirm whether the free headlamp-adjuster prevention-cap service is open for your VIN.
- Ask the dealer to secure the low-beam horizontal headlamp adjustment mechanism so the headlamps stay aimed correctly.
- Bring the recall notice if Ud sent one. If not, reference recall number 11V177 when you call.
- Keep night driving limited until the repair is complete because mis-aimed headlamps can reduce road lighting and make the truck harder for other motorists to see.
What happens at the repair
At the dealer, a Ud technician checks the low beam horizontal headlamp adjustment mechanism and installs a prevention cap over the adjuster so the headlamp aim cannot be changed after manufacture. The remedy text states that this service is free of charge and that the safety recall began on April 18, 2011. If the dealer cannot perform it yet, parts and labor are covered once the repair opens. Confirm parts and scheduling with a Ud dealer before bringing the truck in.

Frequently asked questions
What is recall 11V177?
Recall 11V177 covers 358 2011 Ud UD1800, UD2000, UD2300, UD2600, and UD3300 trucks with headlamps and low-beam horizontal adjusters that were not secured against later adjustment. Improper aim can reduce road illumination or make the truck harder for other motorists to see, increasing crash risk.
What should I do if my 2011 Ud UD1800, UD2000, UD2300, UD2600, or UD3300 is on this recall?
Check your VIN to confirm your specific truck is included in recall 11V177. If it is, contact a franchised Ud dealer and ask for the prevention cap installation over the low-beam horizontal headlamp adjustment mechanism. Reference recall 11V177 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Ud dealers install the prevention cap free of charge. The repair is tied to the recall, not to where you bought the truck.
What is the safety risk?
The safety risk is reduced headlamp performance. If the headlamps or low-beam adjustment mechanism move out of proper aim, the lights can fail to fully illuminate the road or make the truck less visible to other drivers, increasing crash risk.
What if I bought my Ud truck used?
The free recall repair still applies. Recall coverage follows the truck, not the first owner. Check your VIN to confirm whether your 2011 Ud truck is included, then call a franchised Ud dealer with recall 11V177.
