Ram 1500 and Jeep Grand Cherokee diesel face recall over stall risk – Roadshow

Ram’s torquey EcoDiesel has been fairly fashionable in its 1500-Sequence pickup.


Fiat Chrysler Cars is voluntarily recalling choose examples of its 2014 to 2018 Ram 1500 full-size pickup and 2014-2016 Jeep Grand Cherokee SUV over a possible engine stall drawback. The recall, which impacts 58,016 vehicles and SUVs with the corporate’s 3.0-liter EcoDiesel engines, facilities on a crank place sensor half.

Based on the National Highway Traffic Safety Administration, the VM Motori-designed EcoDiesel’s crank place sensor tone wheel — typically often called a relocutor ring — can delaminate. That is dangerous information, because the half helps synchronize the engine’s fuel-injector pulses and camshaft timing, that are regularly optimized for optimum effectivity. If this {hardware} delaminates, the engine might stall, inflicting a security threat.

FCA’s resolution to the issue apparently would not contain changing the crank place sensor tone wheel, which could be robust to entry. As a substitute, the automaker is instructing approved Ram and Jeep technicians to replace the EcoDiesel’s powertrain management module, forcing the powertrain to “keep car propulsion by studying the camshaft place sign within the occasion that the crankshaft place sign is misplaced.” 

It isn’t instantly clear if this firmware patch, carried out freed from cost, will impede the engine’s capacity to detect misfires (one other essential operate of the crank place sensor) or in any other case alter engine efficiency.

No crashes or accidents ensuing from this potential defect are detailed in NHTSA’s official recall announcement.

Affected Ram and Jeep house owners can be notified by the automaker, with the recall marketing campaign scheduled to begin on Oct. 2.
