Recall 14V139 affects 426 2013-2015 Volvo Vnl and Vnm trucks for intake-manifold sensor interference. Free ECM calibration is available at authorized Cummins service facilities.
Volvo is recalling 426 2013-2015 Vnl and Vnm trucks equipped with certain Cummins Westport ISL G and ISX12 G engines because frozen condensation in the intake manifold can interfere with the pressure sensor. That sensor problem can lead to elevated exhaust temperatures or flames from the exhaust pipe, raising the risk of fire or burn injury; the Volvo dealer repair will be free once available.

What's wrong?
The intake manifold on the 2013-2015 Volvo Vnl and Vnm trucks routes air into the engine so the fuel mixture can be controlled. On trucks with the Cummins Westport Model ISL G or ISX12 G engine, the intake manifold pressure sensor reads air pressure in that manifold. The engine control system uses that reading to manage how the engine runs.
In cold weather, condensation inside the intake manifold can freeze. Ice can block or distort the pressure reading at the sensor, so the engine control system no longer gets the intake pressure information it expects. The defect is not a broken sensor alone; it starts with moisture freezing where the sensor needs a clear pressure path.
There is no warning sign before failure. The recall filing does not identify a specific light, sound, smell, or drivability change that gives advance notice before the frozen condensation interferes with sensor operation.
Who's affected?
Both Vnl and Vnm trucks are included across the 2013-2015 model years, with the engine listed as the shared component.
| 2014 Volvo Vnl | Engine |
|---|---|
| 2013 Volvo Vnl | Engine |
| 2013 Volvo Vnm | Engine |
| 2014 Volvo Vnm | Engine |
| 2015 Volvo Vnl | Engine |
| Units affected | 426 |
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?
Improper sensor operation can raise exhaust temperatures or send flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to someone standing near the exhaust. Keep people clear of the exhaust area after the engine has been running and contact the dealer for recall guidance. Repair will be free at any franchised Volvo dealer once available.
What should I do?
- Check your VIN to confirm your 2013-2015 Volvo Vnl or Vnm truck is included in this recall.
- Contact Volvo customer service at 1-800-528-6586 for the current repair routing for recall number 14V139.
- Ask about the free ECM calibration that corrects the intake-manifold sensor issue linked to elevated exhaust temperatures or flames from the exhaust pipe.
- Bring the recall notice if Volvo mailed one. If not, reference Volvo recall RVXX1401 when you call.
- Keep people clear of the exhaust pipe area until the repair is complete, especially after cold-weather operation.
What happens at the repair
At the dealer, a Volvo technician uploads a new ECM calibration to the engine control module. The calibration is meant to correct how the engine system handles intake manifold pressure sensor operation when condensation freezes in cold weather. The final dealer repair will be free once available. Parts and labor are covered under the recall, so ask the service desk to confirm the calibration applies to your VIN before the work begins.

What is recall 14V139?
Recall 14V139 covers 426 2013-2015 Volvo Vnl trucks and 2013-2014 Volvo Vnm trucks with certain Cummins Westport ISL G and ISX12 G engines. Condensation can freeze in the intake manifold and interfere with the intake manifold pressure sensor.
What should I do if my 2013-2015 Volvo Vnl or Vnm is on this recall?
Check your VIN to confirm your specific truck is included in recall 14V139. If it is, contact Volvo or an authorized Cummins service facility and ask for the ECM calibration update. Reference recall number 14V139 and Volvo recall number RVXX1401 when you call.
Is the recall repair free?
Yes. Federal recall law requires the recall repair at no cost, and the remedy states that authorized Cummins service facilities will upload a new ECM calibration free of charge.
What is the safety risk?
The safety risk is elevated exhaust temperatures or flames from the exhaust pipe. Volvo reported that improper sensor operation can increase the risk of a vehicle fire or burn injury to a person near the exhaust pipe.
When did the Volvo recall repair start?
The recall repair began on April 12, 2014. The remedy is an ECM calibration update performed by an authorized Cummins service facility, free of charge.
