Recall 12V252 affects 261 2008-2010 Ud UD3300 trucks for loss of air-brake isolation. Repair is free at any franchised Ud dealer.
Ud is recalling 261 2008-2010 UD3300 trucks equipped with dual steering systems because modifications can remove the separation between the primary and secondary air brake systems. If either system develops an air leak, the truck can lose braking ability and crash risk increases; the dealer repair will be free once available.

What's wrong?
The air brake system on a 2008-2010 Ud UD3300 uses compressed air to apply the service brakes. It is split into primary and secondary brake systems so one side stays isolated from the other. That separation is part of the backup protection built into air brakes.
On affected UD3300 trucks equipped with a dual steering system, vehicle modifications resulted in loss of isolation between the primary and secondary air brake systems. Instead of staying separated, the two brake circuits no longer maintain the required barrier between them. That defeats the intended backup separation in the air brake setup.
There is no warning sign before failure. A driver is not told to expect a dashboard light, sound, pedal change, or other clear symptom before the isolation problem is present.
Who's affected?
The same brake system scope spans the 2008, 2009, and 2010 UD3300 model years.

|---|---|
| 2008 Ud UD3300 | brake system |
| 2009 Ud UD3300 | brake system |
| Units affected | 261 |
The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
An air leak in the primary or secondary air brake system can cause total brake loss, increasing the risk of a crash. Until the repair is handled, drive cautiously and schedule service soon. Repair will be free at any franchised Ud dealer once available.
