Jeep’s parent company, Chrysler has announced a voluntary safety recall affecting 11,980 examples of the 2026 Jeep Grand Wagoneer and Grand Wagoneer L after identifying a software issue that could compromise critical braking and stability systems.
According to documents submitted to the National Highway Traffic Safety Administration (NHTSA), the recall covers 8,628 units of the 2026 Jeep Grand Wagoneer built between June 10, 2025, and February 16, 2026, as well as 3,352 Grand Wagoneer L models produced from June 16, 2025, through February 16, 2026. Every vehicle included in the campaign is believed to contain the defect.
The issue stems from suspect software installed in the Brake System Control Module (BSCM), a component integrated with the brake booster and master cylinder assembly supplied by ZF Group. FCA says the faulty software may disable the vehicle’s Electronic Stability Control (ESC) system and result in the loss of electronic brake assist, two safety features that play a vital role in maintaining vehicle control during emergency maneuvers and hard braking.
Federal Motor Vehicle Safety Standards require ESC to remain functional during all phases of driving, including acceleration, coasting, deceleration, and braking. Likewise, federal braking regulations establish minimum stopping performance requirements for light vehicles. FCA determined that affected vehicles may fail to meet both standards if the software fault occurs.
The automaker warns that drivers may receive no advance indication before the failure happens. Once the Brake System Control Module experiences the fault, multiple warning lights are expected to illuminate in the instrument cluster. Until that point, however, the condition may develop without any prior warning, increasing the risk of a crash.
FCA’s Technical Safety and Regulatory Compliance team launched an investigation on April 7, 2026, after identifying reports of potentially affected vehicles. Engineers and compliance specialists spent the following weeks evaluating the root cause, reviewing production records, and analyzing field and customer assistance data. On June 10, the company confirmed a manufacturing-related issue affecting certain vehicles, and on June 25, FCA’s Vehicle Regulations Committee officially determined that the condition represented a noncompliance with Federal Motor Vehicle Safety Standards 126 and 135.
To resolve the issue, FCA will update the Brake System Control Module software at no cost to owners. The repair does not require replacement of the brake hardware, as the corrective action consists solely of revised software designed to restore proper ESC operation and electronic brake assist functionality.
Dealer notifications are scheduled to begin on July 9, 2026, while owner notification letters are expected to be mailed starting July 30, 2026, as part of a phased recall campaign. Vehicle Identification Numbers (VINs) will become searchable through the NHTSA recall database beginning July 9, allowing owners to verify whether their vehicle is included.
Owners of affected 2026 Jeep Grand Wagoneer and Grand Wagoneer L models are encouraged to schedule the software update promptly once notified to ensure their vehicles continue to meet federal safety standards and maintain full braking and stability control performance.
