U.S. NHTSA TPMS Safety Recall Report 26V559 (manufacturer recall 54D), submitted on September 1, 2026, by Stellantis (FCA US), covers 201,976 vehicles including 2024–2026 Jeep Wagoneer, Grand Wagoneer, and Grand Cherokee models.
Key Details of the Recall:
The Issue: A radio-frequency hub (RFH Module) software error can cause the Tire Pressure Monitoring System (TPMS) to lose its reference data. This fails to comply with Federal Motor Vehicle Safety Standard (FMVSS) No. 138.
The Risk: The system may fail to warn the driver when a tire runs significantly low. Some instrument clusters will display a dash or an error message instead of an actual tire pressure reading, leaving the driver without a reliable low-pressure warning.
The Remedy: Authorized dealerships will reprogram the radio-frequency hub module with updated software at no cost to the vehicle owners.
Timeline: Vehicle Identification Numbers (VINs) became searchable on September 9, 2026. Phased owner notification letters are scheduled to be mailed between September 29 and October 21, 2026.
Owners can contact FCA US customer service at 1-800-853-1403 and reference recall number 54D, or check their vehicle’s status on the official NHTSA Recalls Portal using their 17-character VIN.
