Safety Recall W58 – Crank Shaft – 2014-2018 Ram 1500 & 2014-2016 Jeep Grand Cherokee

August 13, 2020 NHTSA CAMPAIGN NUMBER: 20V475000

Crank Position Sensor Tone Wheel may Delaminate

An engine stall can increase the risk of a crash.

 

NHTSA Campaign Number: 20V475

Manufacturer Chrysler (FCA US LLC)

Components ENGINE AND ENGINE COOLING

Potential Number of Units Affected 58,016

 

Summary

Chrysler (FCA US LLC) is recalling certain 2014-2018 Ram 1500 and 2014-2016 Jeep Grand Cherokee vehicles equipped with 3.0L diesel engines. The crankshaft position sensor tone wheel may delaminate causing the engine to lose its ability to synchronize the fuel injector pulses and cam shaft timing, possibly resulting in an engine stall.

 

Remedy

FCA US will notify owners, and dealers will update 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, free of charge. Owner notification letters were mailed on May 13, 2021. Owners may contact FCA US customer service at 1-800-853-2002. FCA US’s number for this recall is W58.

 

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Dealer Service Instructions for:

Safety Recall W68 / NHTSA 20V-475 Loss of Crankshaft Position

 

NOTE: The Skid Plate labor operation numbers have been updated. 

 

Remedy Available

2014-2016 (DS) Ram 1500 Pickup
2014-2016 (WK) Jeep Grand Cherokee

 

NOTE:  This recall applies only to the above vehicles equipped with a 3.0L engine (sales code EXF).

NOTE:  Some vehicles above may have been identified as not involved in this recall and therefore have been excluded from this recall.

 

IMPORTANT:  Some of the involved vehicles may be in dealer used vehicle inventory.  Dealers should complete this recall service on these vehicles before retail delivery.  Dealers should also perform this recall on vehicles in for service.

Involved vehicles can be determined by using the VIP inquiry process.

 

Subject

The magnetic material attached to the tone wheel on about 240 of the above vehicles provides a signal to the crankshaft position sensor. If this signal material is lost, the engine loses its ability to synchronize injector pulses and cam timing. This loss of crankshaft position can result in an engine stall, as well as loss of the ability to restart the engine. A loss of motive power can cause a vehicle crash without prior warning.

 

Repair

Replace the tone wheel.

 

Alternate Transportation

Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if inspection determines that tone wheel replacement is required and the vehicle must be held overnight.
