Dealer Service Instructions for:
Safety Recall Y67 / NHTSA 21V-729 Radio Software Update
NOTE: USB flash drive must not exceed 16GB Page 2 Special Tools section and Page 4 Step 1. Format USB flash drive to NTFS file type Page 4, Step 3.
Remedy Available
2021 (WL) Jeep Grand Cherokee
NOTE: This recall applies only to the above vehicles equipped with a:
- Uconnect 5 navigation radio with 10.1″ display (United States sales code UBN)
- Uconnect 5 navigation radio with 8.4″ display (United States sales code UBL)
- Uconnect 5 radio with 8.4″ display (United States sales code UBF)
NOTE: Some vehicles above may have been identified as not involved in this recall and therefore have been excluded from this recall.
Subject
The radio software on about 56,100 of the above vehicles may malfunction during shutdown and fail to produce a display on the radio screen during subsequent key cycles. There is no warning that the rearview camera image will not display; however, the vehicle operator will notice that the rearview image is not displayed if attempting to reference the image while backing. If this warning is not heeded, backing without verifying it is safe to do so could lead to an increased risk of injury to people outside the vehicle.
The condition above fails to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 111 – Rearview Mirrors, which requires that the rear visibility system default to the rearview image being visible, and meet the requirements of FMVSS No. 111 S6.2.1 (field of view) and S6.2.2 (image size) at the beginning of each backing event, regardless of any modifications to the field of view that the driver had previously selected. Suspect vehicles may not display the rear view image during a backing event.
Repair
Inspect and if necessary, update the radio software version.
