Ford Motor Company (Ford) is recalling certain 2020-2023 Mustang vehicles. The brake fluid level sensor may not activate the visual warning indicator when the brake fluid is low. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 135, "Light Vehicle Brake Systems."
Without a low brake fluid warning light, the vehicle may be driven with low brake fluid, reducing braking performance and increasing the risk of a crash.
Dealers will update the body control module software, free of charge. Owner notification letters were mailed December 21, 2023. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 23C35.
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.
