  BACK OVER PREVENTION: SENSING SYSTEM: CAMERA · EXTERIOR LIGHTING:BRAKE LIGHTS

  Chrysler (FCA US, LLC) is recalling certain 2018-2024 Jeep Wrangler vehicles. The wiring harness for the rearview camera and the center brake light may short circuit, which can disable the rearview camera image and center brake light. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard numbers 111, "Rear Visibility" and 108, "Lamps, Reflective Devices, and Associated Equipment."

  Risk: A rearview camera image that does not display decreases the driver's visibility, increasing the risk of a crash. Additionally, a center brake light that fails to illuminate can fail to indicate to other drivers that the vehicle is slowing down, increasing the risk of a crash.

  Remedy: Dealers replaced the harness for the center brake light and rearview camera and/or the spare tire carrier/harness assembly, as necessary, free of charge. All vehicles were repaired by January 15, 2024. Owner notification letters were mailed September 26, 2024. Owners may contact FCA US, LLC customer service at 1-800-853-1403. FCA US, LLC's number for this recall is 77B.

   The forward collision/emergency brake engages when it is not needed, necessary or appropriate, and even when the brake pedel is already being pressed. I have adjusted the sensitivity of the emergency braking and forward collision system and I still have this issue.

   I have a 2021 Jeep Wrangler 4XE Rubicon. My vehicle has been recalled three times for updates.

The second one was for risk of fire from a faulty high voltage battery driving or parked. The third recall call was to update software for the high voltage battery in which doing so caused my vehicle not to fully charge and to lose power when…

   I had the most recent incident driving Westbound in the evening hours shortly before Sunset around October 10, 2024.
