Vehicle Might Not Display When Light Goes Out...

Stellantis (FCA US, LLC) is recalling a certain number of 2022 Jeep® Grand Cherokee (WL74) and Grand Cherokee L (WL75) vehicles, due to a software programming error that doesn’t relay information of any failure with the vehicle’s turn signals, if there was an issue. The issue means the vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard #108, “Lamps, Reflective Devices, and Associated Equipment.”

2022 Jeep® Grand Cherokee Summit Reserve 4×4. (Jeep).

The turn signal flash rate on about 65 units 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 suspect period began on Wednesday, January 26th, 2022, when incorrect configuration parameters were introduced into vehicle production, and ended on the same day Wednesday, January 26th, 2022, when the correct configuration parameters were implemented in vehicle production. Supplier and vehicle production records were used to identify the suspect period.

Similar vehicles not included in this recall were built before or after the suspect period or were repaired prior to release from the production plant.

The total affected vehicles by this recall –

  • 16 units – Jeep Grand Cherokee (WL74) two-row
  • 49 units – Jeep Grand Cherokee L (WL75) three-row

Recall Chronology:

    organization was notified by the assembly plant that some 2022 MY Grand Cherokee and Grand Cherokee L

  • On Tuesday, February 1st, 2022, the FCA US TSRC organization opened an investigation based on information that the turn signal flash rate was rapid.
