Certain ambulance package vehicles with 6.7L diesel engines may experience a "stop safety now" warning message and 5 audible chimes while the vehicles gradually loses power, eventually resulting in the engine stalling when speed falls below 5 km/h. If this were to occur while the ambulance is transporting a patient, engine shutdown with no ability to restart could interfere with patient care and increase the risk of injury to the patient. Correction: Dealers will replace the exhaust gas temperature (EGT) sensor located downstream of the diesel particulate filter (DPF).
