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 asking owners of certain 2014-2017 Jeep Cherokee SUVs to return to their dealership to repair a problem affecting the two speed power transfer unit (PTU) in their vehicles. The suspect period began in April 2014 when more robust differential input splines were used to manufacture PTUs.
According to the defect report, movement between the differential input splines and the transmission output shaft may result in the input spline teeth wearing. Eventually this will cause a loss of engagement between the transmission and the differential, and torque will not be transferred to the wheels. The vehicle will loose motive power and there will be no “Park” function while the vehicle is stationary.
Dealers will perform a software update that will maintain vehicle propulsion by engaging rear wheel drive and prevent rolling in “Park” by activating the electronic parking brake if a failed input spline occurs. FCA’s number for this recall is W47 and the NHTSA campaign number is 20V-343.
Fiat Chrysler Automobiles (FCA) have discovered that a safety defect exists in certain 2017-2020 Chrysler Pacifica Hybrid vehicles. Chrysler advises owners to take additional safety measures until the problem can be fixed by their dealership.
“Note: Consumers are advised to exercise the following precautions until the vehicle has the final repair completed: Do not park inside of buildings, near structures or other vehicles. Additionally, keep liquids out of the backseat area, including but not limited to beverages, wet items, umbrellas, or bottled liquids that may leak.”
According to the defect report, some 2017-2020 Chrysler Pacifica Hybrid vehicles may experience a high resistance electrical connection at the 12 volt isolator post. This high resistance could lead to prolonged heating and a potential vehicle fire even with the vehicle shut off.
A remedy for this recall is currently under development. In the meantime, notices will be sent out to owners instructing them to return to their dealers to have an interim inspection of this connection. If the inspection indicates the joint is compromised, owners will receive a loaner vehicle until a fix is developed.
Interim notifications are expected to begin around June 22, 2020. FCA US LLC’s number for this recall is W46 and the NHTSA campaign number is 20V-334.
Chrysler will be contacting the owners of certain 2019 Jeep Grand Cherokee and 2019 Dodge Durango vehicles because of a problem affecting the powertrain of their vehicles.
According to the defect report, the front differential may have been built with pinion gears that were not sufficiently hardened. Over time the gears could wear down until torque power cannot be transferred from the drivetrain to the front wheels. If this happens drivers will experience loss of power and loss of the “Park” function when stationary. Prior to loss of power, drivers may notice a gear whine or grinding noise coming from the drivetrain
Those receiving notices will be asked to return to their dealerships to have the front differential replaced. This recall is expected to begin May 15, 2020. Chrysler’s number for this recall is W22 and the NHTSA campaign number is 20V-183.
Chrysler will be contacting the owners of certain 2020 Jeep Gladiator and 2018-2020 Jeep Wrangler vehicles, equipped with manual transmissions. These vehicles have a defective power train that could increase the risk of an accident.
According to the defect report, the clutch pressure plate could overheat and break. Fragments from the pressure plate could fracture the transmission case where debris could enter. Debris entering the transmission could result in loss of propulsion or allow heated debris to contact ignition sources, potentially leading to a vehicle fire. In some circumstances, vehicle occupants may notice a burnt clutch odor, or the driver may notice abnormal clutch pedal travel prior to the failure.
A fix for this recall is still under development. Chrysler’s number for this recall is W12 and the NHTSA campaign number is 20V-124.
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 notifying the owners of certain 2020 Jeep Wrangler SUVs because of a safety problem affecting the suspension in their vehicles.
According to the defect report, the left side lower control arm bracket may have been out of position during the welding process. This off location weld is weak and could break, allowing the lower control arm to separate from the axle. If this happens, the driver could experience a loss of vehicle control and/or the lower control arm bracket may separate completely, resulting in dangerous road debris. Prior to compete separation of the bracket from the axle, the driver may experience a front end noise or a steering vibration.
Those receiving notices will be asked to return to their dealers to have the front axle inspected and replaced as necessary. Chrysler’s number for this recall is W01 and the NHTSA campaign number is 20V-042.
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.
