Remedy

Dealers will update the body control module software, free of charge. Owner notification letters were mailed April 28, 2022. Owners may contact FCA US, LLC customer service at 1-800-853-1403. FCA US, LLC’s number for this recall is Z35.

New Safety Recall Advanced Communication – Z35

FCA US LLC (FCA US) has announced a safety recall on certain 2022 Model Year (WL) Jeep® Grand Cherokee and Grand Cherokee L vehicles.

 

REASON FOR THIS SAFETY RECALL

Some of the above vehicles may have been built with a turn signal flash rate at the same flash rate designed to indicate a failed turn indicator and would not indicate a significant change in the flashing rate if/when there is a failure of one or more turn signal lamps. This could cause a crash without prior warning.

The condition described above does not comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 108 S9.3.6 which requires that “Failure of one or more turn signal lamps […] must be indicated by the turn signal pilot indicator by […] a significant change in the flashing rate”.

 

SERVICE ACTION

FCA US will conduct a voluntary safety recall to update configuration parameters in the Body Control Module (BCM). The remedy for this condition is not currently available. Dealers will be notified of the launch of this safety recall by way of established communication methods. This recall is estimated to launch in the 2nd Quarter of 2022.

Dealer Service Instructions for:

Safety Recall Z35 / NHTSA 22V-249 Turn Signal Flash Rate

 

Remedy Available

2022 (WL) Jeep Grand Cherokee and Grand Cherokee L

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 new vehicle inventory.  Federal law requires you to complete this recall service on these vehicles before retail delivery.  Dealers should also consider this requirement to apply to used vehicle inventory and should perform this recall on vehicles in for service.  Involved vehicles can be determined by using the VIP inquiry process.

 

Subject

The turn signal flash rate on about 70 of the above vehicles may be incorrect. A turn signal that flashes at the same rate designed to indicate a failed turn signal would not provide the driver notification of a failed turn signal lamp. This could cause a crash without prior warning.

The condition described above does not comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 108 S9.3.6 which requires that “Failure of one or more turn signal lamps […] must be indicated by the turn signal pilot indicator by […] a significant change in the flashing rate”.

 

Repair

Use wiTech to reconfigure the Body Control Module (BCM).

 

Parts Information

No parts are required to perform this service procedure.

 

Parts Return

No parts return required for this campaign.

 

Special Tools

The following special tools are required to perform this repair:

➢ NPN wiTECH MDP (Mopar Diagnostic Pod)
➢ NPN Laptop Computer
➢ NPN wiTECH Software

 

Service Procedure

A. Reconfigure the BCM

 

NOTE: The wiTECH scan tool must be used to perform this recall.  The wiTECH software is required to be at the latest release level before performing this procedure. 

 

  1. Open the hood. Install a battery charger and verify that the charging rate provides 13.0 to 13.5 volts.  Do not allow the charger to time out during the flash process.  Set the battery charger timer (if so equipped) to continuous charge.

 

NOTE:  Use an accurate stand-alone voltmeter.  The battery charger volt meter may not be sufficiently accurate.  If voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage.

 

  1. Place the ignition in the “RUN” position.

 

  1. Connect the wiTECH MDP to the vehicle data link connector.

 

  1. Open the wiTECH 2.0 website.

 

  1. Enter your “User id” and “Password” and your “Dealer Code”, then select “Sign In” at the bottom of the screen.  Click “Accept”.

 

  1. From the “Vehicle Selection” screen, select the vehicle to be updated.

 

  1. From the “Action Items” screen, from the left column, select “Guided Diagnostics”.

 

  1. Select “Restore Vehicle Configuration” and follow on-screen prompts.

 

NOTE: If the “Restore Vehicle Configuration” option is not available, the vehicle is up to date. Claim the “Restore Vehicle Configuration” LOP to close the recall. 

 

Note: Ensure the following parameters change throughout the routine (Figure 1).

 

  1. After configuration is updated, confirm the flash rate of all 4 lamps (front headlamps and rear tail lamps) are the same.

 


Chronology :

  • On January 28, 2022, the FCA US LLC (“FCA US”) Technical Safety and Regulatory Compliance (“TSRC”) organization was notified by the assembly plant that some 2022 MY Grand Cherokee and Grand Cherokee L vehicles were built with an incorrect configuration parameter for the turn signal flash rate.
  • On February 1, 2022, the FCA US TSRC organization opened an investigation based on information that the turn signal flash rate was rapid.
  • During February 2022, meetings were held between FCA US engineering and TSRC to better understand the failure mode.
  • During March 2022, FCA US TSRC, Engineering, Manufacturing, and Supplier Operations worked in partnership to determine the suspect population.
  • On March 23, 2022, the FCA US TSRC organization recognized a vehicle build issue existed on certain vehicles related to the turn signal flash rate, potentially not in compliance with FMVSS No. 108.
  • On April 7, 2022, FCA US determined, through the Vehicle Regulations Committee, to conduct a voluntary safety recall of the affected vehicles.
