Recall 14V080 covers 3,258 2008-2015 Freightliner vehicles for intake-manifold sensor interference. Free ECM calibration is available at Cummins service facilities.
Freightliner is recalling 3,258 2008-2015 Cascadia, M2, Saf-T-Liner Hdx, LT8500, and 114SD vehicles with Cummins Westport Model ISL G and ISX12 G engines because condensation in the intake manifold can freeze and disrupt the pressure sensor. That sensor malfunction can raise exhaust temperatures or send flames from the exhaust pipe, raising the risk of a vehicle fire or burn injury; the dealer repair will be free once available.

What's wrong?
The intake manifold feeds air into the engine. Its pressure sensor reads the air pressure inside that manifold, then sends that signal to the engine control system so fuel and air delivery stay matched. The system depends on a clear, accurate pressure path between the manifold and the sensor.
On affected Freightliner Cascadia, M2, Saf-T-Liner Hdx, LT8500, and 114SD vehicles with Cummins Westport ISL G or ISX12 G engines, condensation can collect inside the intake manifold. In cold weather, that moisture can freeze and interfere with the pressure sensor. When the reading is wrong, the engine control system is working from bad air-pressure information instead of the actual condition in the manifold.
There is no warning sign before failure. Because the problem is tied to ice inside the intake manifold, the driver does not get a reliable early symptom from the recall record. Treat cold-weather engine warnings or drivability changes as a reason to call a Freightliner dealer.

A matching year and model does not confirm inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.
What's the safety risk?
The sensor malfunction can raise exhaust temperatures or send flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to someone nearby. Keep people away from the exhaust area and schedule service soon. Repair will be free at any franchised Freightliner dealer once available.
What should I do?
- Check your VIN to confirm your 2008-2015 Freightliner Cascadia, M2, Saf-T-Liner Hdx, LT8500, or 114SD is included in this recall.
- Contact a franchised Freightliner dealer or authorized Cummins service facility to ask whether the free ECM calibration is open for your VIN.
- Reference recall number 14V080 when you call, and ask whether the engine calibration addresses the intake-manifold sensor issue that raises exhaust temperature and fire risk.
- Bring the recall notice if Freightliner, Cummins, or Cummins Westport mailed one to you.
- Avoid parking or idling near dry grass, fuel, or people standing close to the exhaust until the calibration is complete.
What happens at the repair
The repair plan for recall 14V080 calls for a Freightliner technician or authorized Cummins service facility to upload a new ECM calibration to the engine control module. That software update is meant to correct how the engine system handles intake manifold pressure sensor operation in cold weather. The source notice says the recall began on April 12, 2014, but the current remedy status is not listed in this input. Once the repair is available for your VIN, the ECM calibration update is free under the recall.

Frequently asked questions
What is recall 14V080?
Recall 14V080 covers 3,258 2008-2015 Freightliner Cascadia, M2, Saf-T-Liner Hdx, LT8500, and 114SD vehicles with Cummins Westport natural gas engines. Condensation in the intake manifold can freeze in cold weather and interfere with the intake manifold pressure sensor.
What should I do if my 2008-2015 Freightliner Cascadia, M2, Saf-T-Liner Hdx, LT8500, or 114SD is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 14V080. If it is, contact Freightliner or an authorized Cummins service facility and reference recall FL-660. The repair is a new ECM calibration, and the recall repair is free.
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 the new ECM calibration free of charge. Reference recall 14V080 or Freightliner recall FL-660 when arranging service.
What is the safety risk?
The intake manifold pressure sensor problem can cause elevated exhaust temperatures or flames from the exhaust pipe. That increases the risk of a vehicle fire or burn injury to a person near the exhaust pipe. The free repair corrects the engine calibration tied to this defect.
What if I bought this vehicle used?
The free recall repair still applies. Recall coverage follows the vehicle, not the first owner. Check your VIN to confirm whether your specific 2008-2015 Freightliner vehicle is included, then contact Freightliner or an authorized Cummins service facility with recall number 14V080.
