What's wrong?
The electric auxiliary power unit on the 2012-2014 Volvo Vnl is a separate electrical unit that lets the truck run sleeper-cab equipment while the main engine is off. On these trucks, the affected unit is the Idle Free Systems BA600 APU. Its metal housing and mounting hardware hold the unit to the truck so vibration and road loads do not shift it.
On affected Volvo Vnl trucks, the APU housing mounting points can crack and tear. The power-unit mounting bolts can also loosen or fail. When the housing or hardware loses strength, the APU is no longer held as designed. Volvo's repair uses a welded gusset upgrade kit to strengthen the APU C-channels, which are the support rails, and stronger clamping brackets.
There is no warning sign before failure. An owner is not told to watch for a light, sound, or dashboard message before the mounting points or bolts give way.
Who's affected?
Covers Vnl trucks from the 2012, 2013, and 2014 model years, with the same electrical-system component listed for each year.

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?
Cracked or torn mounting points, loose bolts, or failed bolts can let the power unit detach from the truck. A detached unit becomes a road hazard and increases the risk of a crash. Until the inspection and bracket repair are complete, drive cautiously and arrange service soon. Repair is free at any franchised Volvo dealer.
What should I do?
- Check your VIN to confirm your 2012-2014 Volvo Vnl is included in this recall.
- Contact a franchised Volvo dealer to schedule the free APU inspection, gusset upgrade, and stronger clamping bracket repair that keeps the auxiliary power unit attached to the truck.
- Bring the recall notice if Volvo mailed one. If not, reference recall number 15V634 when you call.
- Avoid driving if the APU housing looks cracked, torn, loose, or shifted; ask the dealer before moving the truck.
What happens at the repair
At the dealer, a Volvo technician inspects the electric auxiliary power unit for cracked or torn mounting points and loose power unit mounting bolts. If the APU shows damage, the technician installs a welded gusset upgrade kit to strengthen the APU C-channels. Every affected unit also gets stronger clamping brackets. The recall repair is available now, and parts and labor are free under campaign 15V634.
