Jeep Wrangler, Jeep Gladiator, and Ram 1500 models are being recalled in the United States as they use a high-pressure fuel pump that could fail prematurely.
FCA US has revealed that 3.0-liter diesel engines introduced into production from May 29, 2019 have faulty high-pressure fuel pumps. The automaker hasn’t said why the fuel pump could wear prematurely but says that if it does, it could introduce internally failed component debris into the fuel system, potentially causing fuel starvation.
If this were to occur, it could result in an unexpected loss of power, increasing the risk of a crash and injury. Owners of impacted models may notice a Malfunction Indicator Lamp, service Electronic Throttle Control indicator, a fuel leak at the high-pressure fuel pump, or excessive noise from the fuel pump.
