October 14, 2021 NHTSA CAMPAIGN NUMBER: 21V797000
Difficulty activating the headlight high beams may result in reduced visibility, increasing the risk of a crash.
NHTSA Campaign Number: 21V797
Manufacturer Chrysler (FCA US, LLC)
Components EXTERIOR LIGHTING
Potential Number of Units Affected 7,082
Chrysler (FCA US, LLC) is recalling certain 2021 Jeep Grand Cherokee L vehicles not equipped with automatic high beams. When the master lighting switch is set to the auto position, the high beam headlights will not activate unless the master lighting switch is first changed to the ‘on” position. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, “Lamps, Reflective Devices, and Associated Equipment.”
Dealers will reprogram the vehicles, free of charge. Owner notification letters were mailed October 28, 2021. Owners may contact FCA US, LLC customer service at 1-800-853-1403. FCA US, LLC’s number for this recall is Y66.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.
Dealer Service Instructions for:
|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.
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.
No parts are required to perform this service procedure.
No parts return required for this campaign.
The following special tools are required to perform this repair:
|➢ NPN||wiTECH MDP (Mopar Diagnostic Pod)|
|➢ NPN||Laptop Computer|
|➢ NPN||wiTECH Software|
