Some 2014-2016 Jeep Grand Cherokee and 2014-2018 RAM 1500 vehicles equipped with 3.0L diesel engines may have been manufactured with crankshaft tone wheels that could experience magnetic signal material delamination.
The magnetic material attached to the tone wheel provides a signal to the crankshaft position sensor. If this material delaminates, the engine will lose its ability to synchronize injector pulses and cam timing. Loss of crankshaft position can result in an engine stall and the inability to restart. The problem can occur without prior warning.
The remedy for this condition is not currently available. Dealers will stop the engine from stalling by updating the powertrain control module software to maintain vehicle propulsion by reading the camshaft position signal in the event that the crankshaft position signal is lost. If tone wheel failure occurs, the engine warning light will illuminate but the vehicle will not stall.
The recall to update the powertrain control module software is expected to begin in October. FCA’s number for this recall is W58 and the NHTSA campaign number is 20V-475.
Chrysler will be contacting the owners of certain 2019-2020 Ram 2500 and 2019-2020 Ram 3500 pickups equipped with six-speed automatic (68RFE) transmissions, because of a problem affecting the transmissions in their trucks.
According to the defect report, these vehicles could experience a build up of pressure and heat inside the transmission strong enough to expel fluid from the dip stick tube. If the fluid comes in contact with the turbocharger or other ignition sources within the engine compartment, it could lead to a fire. Vehicle occupants may notice odd smalls, noises or transmission surging prior to a vehicle fire.
Dealers will fix the problem by replacing the transmission valve body separator plate and reprogramming the powertrain control module. Chrysler’s number for this recall is W03 and the NHTSA campaign number is 20V-043.
Chrysler will be contacting the owners of certain 2014-2019 Ram 1500 and 1500 Classic Pickup trucks equipped with 3.0L Eco Diesel engines because of a vehicle safety problem.
According to the defect report, the Exhaust Gas Re-circulation (EGR) coolers are susceptible to thermal fatigue and could crack over time. Th crack could allow pre-heated vaporized coolant to enter the EGR system and could combust inside the intake manifold, causing a vehicle fire. Drivers may be alerted there is a problem through a noticeable loss of coolant, lack of heater function and potentially a Malfunction Indicator Lamp.
Owners receiving notices will be asked to return to their dealerships to have the EGR cooler replaced. Dealers will also inspect and replace the intake manifold as necessary. Chrysler’s number for this recall is VB1 and the NHTSA campaign number is 19V-757.
Chrysler will be contacting a small number of 2016-2017 RAM 1500 owners regarding a problem affecting their vehicles power train. According to the defect report, the differential retaining screw pin could become loose and contact the bearing cap. If the pin comes out of position, the differential pinion spider gears, the loose screw or the pin itself could make contact with components inside the differential and cause it to break and/or lock up.
Dealers will inspect and replace the differential pin retaining screw in all affected vehicles. If the inspection finds the retaining screw loose or damaged, the entire rear axle assembly will be replaced. Owners wanting more information about the problem are asked to contact Chrysler customer service at 1-800-853-1403. Chrysler’s number for this recall is T20 and the NHTSA campaign number is 17V-198.
Chrysler (FCA US LLC) will be contacting the owners of certain 2015 RAM 2500 & 3500 trucks about a problem affecting the steering system. Some of these vehicles may have been built with inadequate front track bar frame bracket welds. If these welds brake, steering response will be reduced or lost. Drivers may experience an off center steering wheel prior to the failure.
Dealers will weld on a new track bar frame bracket or replace the frame of the vehicle. Owners wanting more information about the problem are asked to contact Chrysler customer service at 1-800-853-1403. Chrysler’s number for this recall is S58 and the NHTSA campaign number is 16V-559.
Fiat Chrysler America (FCA) will be contacting the owners of certain Chrysler, Dodge, and RAM minivans, regarding a problem that could affect the transmissions in their vehicles. Dimensional variances in the transmission pump rotor pocket could result in seized and broken rotors. If this happens, the transmission will lose hydraulic pressure and the vehicle may lose power.
The vehicles affected include:
Chrysler will be contacting the owners of certain 2016 RAM 3500, 4500 and 5500 trucks about a problem affecting their vehicles powertrain system. The transfer case main output shaft may have been manufactured misshapen, creating voids that could result in a shaft fracture. If the main output shaft fractures, the vehicle will lose motive power and the driver may be unable to shift into “PARK”.
Dealers will correct the problem by replacing the transfer case. For more information about the problem, owners are asked to contact Chrysler customer service at 1-800-853-1403. Chrysler’s number for this recall is S48 and the NHTSA campaign number is 16V-495.
Chrysler will be contacting the owners of certain Chrysler, Jeep and RAM vehicles, about a problem affecting their 9-speed automatic transmissions. According to the defect report filed with the NHTSA, some vehicles may have been built with a trans-axle wire harness with insufficient wire terminal crimps. These crimps could result in a high resistance which will cause the on board diagnostic system to set a Diagnostic Trouble Code (DTC) and shift the vehicle into neutral. Continue reading
