New Safety Recall Advanced Communication – 12B

FCA US LLC (FCA US) has announced a safety recall on certain 2023 and 2024 Model Year (WL) Jeep® Grand Cherokee and Grand Cherokee L vehicles.

 

REASON FOR THIS SAFETY RECALL

Some of the above vehicles may not be equipped with the Auto High Beam Headlamp Control feature and may not turn on the high beam headlamps when requested if the master lighting switch is set to the AUTO headlamp position. If the master lighting switch is set to the auto position, activation of the high beams requires turning the master lighting switch to “ON” and then toggling the stalk. The inability to conveniently activate high beam headlights may result in reduced visibility for the driver, which can cause a vehicle crash without prior warning.
Federal Motor Vehicle Safety Standard (FMVSS) No. 108 S9.4 requires that “Each vehicle must have a means of switching between lower and upper beams designed and located so that it may be operated conveniently by a simple movement of the driver’s hand…”

 

SERVICE ACTION

FCA US will conduct a voluntary safety recall to reprogram the vehicle. 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 1st Quarter of 2024.
