Ford F-550 Recall 15V371: Engine may shut off and won't restart, delaying emergency response

NHTSA campaign 15V371, reported June 15, 2015, 8 vehicles potentially affected.

What this recall means for you

Certain emergency vehicles built on a 2014-2015 Ford F-550 chassis may incorrectly detect an Exhaust Gas Temperature Sensor fault. This false fault tells the vehicle it is overheating, so the engine management system shuts the engine down and prevents it from restarting right away.

Because the engine can stop and then needs a cool-down period before it will start again, a vehicle used for emergency response could be delayed in reaching or assisting someone who needs medical help, which raises the risk of injury.

HME, Inc. will notify owners, and dealers will update the Powertrain Control Module (PCM) software at no cost to you. Contact HME customer service at 1-616-261-2636 for more information, and check your vehicle identification number (VIN) for any open recalls.
