Chrysler (FCA US, LLC) is recalling 11,980 model-year 2026 Jeep Grand Wagoneer and Grand Wagoneer L SUVs because a Brake System Control Module defect can disable electronic stability control and electronic brake assist. The recall, filed under NHTSA Campaign Number 26V414, covers vehicles built with suspect brake booster and master cylinder assemblies supplied by ZF Group. FCA US estimates 100 percent of the affected population carries the defect. Dealers will update the module’s software free of charge.
Highlights
- 11,980 total vehicles affected: 3,352 Jeep Grand Wagoneer L units and 8,628 Jeep Grand Wagoneer units
- Estimated 100% defect rate across the recall population
- No warning before failure; once the module faults, multiple instrument-cluster warning lights may illuminate
- Owner notification letters expected to begin on or about July 30, 2026
Scope of the Recall
The recall splits across two nameplates built on overlapping but distinct production windows. The 3,352 affected Grand Wagoneer L units were built June 16, 2025, through February 16, 2026, while the 8,628 affected Grand Wagoneer units were built June 10, 2025, through February 16, 2026. FCA US determined the suspect period using supplier and vehicle production records; vehicles built outside that window either used a different module calibration or were corrected before leaving plant control.
Nature of the Defect
The suspect component is the brake booster and master cylinder assembly, which houses the Brake System Control Module (BSCM). According to the filing, suspect BSCM software may disable electronic stability control (ESC) and cause a loss of electronic brake assist. FCA US cited noncompliance with two federal standards: Federal Motor Vehicle Safety Standard No. 126, which requires ESC to remain operational through acceleration, coasting, and braking, and FMVSS No. 135, governing light-vehicle brake system performance. The filing states a BSCM fault can cause a vehicle crash without prior warning, and that no warning occurs before the failure — though multiple dashboard lights may illuminate once the module has already faulted.
The suspect assemblies were supplied by ZF Group, headquartered in Northville, Michigan. Three part numbers are named in the filing: 68608206AG, 68608206AH, and 68608206AI.
Chronology
FCA US’s Technical Safety and Regulatory Compliance (TSRC) organization opened its investigation on April 7, 2026, into Grand Wagoneer and Grand Wagoneer L vehicles potentially built with suspect BSCM software. Through April and May, TSRC worked with FCA Engineering to assess root cause, customer consequence, and vehicle scope, alongside a parallel review of field and customer assistance records. TSRC recognized the build issue on June 10, 2026, and the Vehicle Regulations Committee formally determined the FMVSS 126 and 135 noncompliance on June 25, 2026.
Remedy and Notification Timeline
The remedy is a software update to the BSCM, performed by dealers at no cost to owners. FCA US will notify dealers on or about July 9, 2026, the same date VINs become searchable on NHTSA.gov, with owner notification letters following on a phased basis beginning on or about July 30, 2026. Owners may contact FCA US customer service at 800-853-1403 and reference recall number 50D. FCA US is using its general reimbursement plan on file for owners who paid for related repairs before notification.
Pattern of ZF-Supplied Brake Module Recalls
This is the second 2026 Stellantis brake-control-module recall tracing to ZF-supplied hardware. In April, Chrysler recalled 241 model-year 2026 Jeep Cherokee SUVs for a ZF-supplied BSCM defect that could disable ABS and ESC. Earlier in 2026, a separate campaign covered more than 456,000 Ram and Jeep vehicles for an unrelated trailer tow module defect. The Grand Wagoneer campaign is by far the largest of the three by unit count involving a stability-control or brake-assist function.
