Ford Motor Company (Ford) is recalling approximately 456,565 units of its 2021 to 2024 Bronco Sport and 2022 to 2023 Maverick vehicles. According to recent documents filed with the National Highway Traffic Safety Administration (NHTSA), body and powertrain control modules may fail to detect a change in the 12-volt battery state of charge.
Recall Chronology –
- On October 25, 2023, The National Highway Traffic Safety Administration’s Office of Defects Investigation (NHTSA ODI) requested information regarding allegations of loss of motive power (LOMP) followed by a loss of 12-volt accessories on 2021 MY Bronco Sport vehicles. NHTSA provided 29 potentially responsive Vehicle Owner Questionnaires (VOQs) that indicated that most customers’ concerns were resolved with a 12-volt battery replacement.
- On November 28, 2023, Ford’s Critical Concern Review Group (CCRG) investigated this concern.
- From November 2023 through January 2024, the Low Voltage Power Supply Engineering team evaluated field returns and warranty data for 2021 Bronco Sport vehicles focusing on 12-volt batteries and low voltage systems.
- From December 2023 through March 2024, the Low Voltage Power Supply Engineering team conducted system and vehicle level testing and teardowns with batteries with various physical conditions and state of charge. The testing revealed that the Body Control Module (BCM) and Powertrain Control Module (PCM) calibrations are unable to detect the battery failure on these vehicles, which can result in a LOMP if the alternator is unable to keep up with the electrical load demand or if an Auto Stop-Start event is initiated.
- On January 31, 2024, NHTSA’s ODI opened Preliminary Investigation PE24-002 into this concern.
- As of February 8, 2024, Ford is aware of 917 warranty reports, 11 field reports, and 54 customer complaints related to this concern. There are 3 unverified reports of fire and 2 property damage claims.
- As of February 8, 2024, Ford is not aware of any accidents or injuries attributed to this condition.
- On April 5, 2024, Ford’s Field Review Committee reviewed the concern and approved a field action.
Dealers will, free of charge, recalibrate the body and powertrain control modules. Owner notification letters are expected to be mailed on May 13, 2024. Owners may contact Ford customer service at 1-866-436-7332. Ford’s number for this recall is 24S24.
