New Safety Recall Advanced Communication – Y66

FCA US LLC (FCA US) has announced a safety recall on certain 2021 Model Year (WL) Jeep Grand Cherokee L vehicles equipped with Laredo Trim, and without Auto High Beam Headlamp Control [sales code LMS].

 

REASON FOR THIS SAFETY RECALL

The condition described above does not comply with 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…” 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.

 

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 4th Quarter of 2021.

Dealer Service Instructions for:

Safety Recall Y66 / NHTSA 21V-797 High Beam Headlamps

 

Remedy Available

2021 (WL) Jeep Grand Cherokee L

 

NOTE:  This recall applies only to the above vehicles equipped with Laredo trim and without Auto High Beam Headlamps (sales code LMS).

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 high beam headlamps on about 7,000 of the above vehicles may not respond to requests from the high beam switch. 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.

The condition above fails to conform to the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108 S9.4 – Lamps, reflective devices, and assoc. equipment.

 

Repair

Execute a wiTECH routine which will make the Auto Dim High Beam Headlamps OFF request available through the radio.
