Chrysler* (FCA US) is recalling ~120,000 2026 model year Jeep Grand Wagoneer and Jeep Grand Wagoneer L SUVs. The brake system control module software may cause a loss of electronic stability control and a loss of electronic brake assist. These SUVs go not comply with the requirements of Federal Motor Vehicle Safety Standard numbers 126, “Electronic Stability Control Systems” and 135, “Light Vehicle Brake Systems.” The supplier is ZF group.
“The Brake System Control Module (BSCM) may have been built with software which may disable Electronic Stability Control (ESC) and electronic brake assist. A loss of ESC function and/or electronic brake assist can cause a vehicle crash without prior warning,” Chrysler said on the mandatory safety defect recall notice, that the National Highway Traffic Safety Administration (NHTSA) made public this week.
There is no warning to the driver prior to failure. Once the BSCM has faulted, multiple warning lights may illuminate in the instrument panel cluster. Dealers will update the brake system control module software, free of charge as required by Federal safety regulations. Owner notification letters are expected to be mailed 30 July 2026. Owners may contact Chrysler customer service at 800-853-1403. Chrysler’s number for this recall is 50D. Vehicle Identification Numbers (VINs) involved in this recall are searchable on NHTSA.gov.
