Stellantis subsidiary Chrysler is recalling 201,976 Jeep SUVs in the United States because a software error can leave the tire-pressure monitoring system blind to a flat or sagging tire. The affected vehicles span nine Jeep model lines, from the Grand Cherokee to the Grand Wagoneer L plug-in hybrid. The National Highway Traffic Safety Administration says the defect puts the vehicles out of compliance with a federal safety standard, not merely short of a company quality target.
A software error inside the radio frequency hub
The failure sits in code rather than hardware. The manufacturer files the campaign internally as recall 54D. The component is listed as tires: pressure monitoring and regulating systems, and the fix targets the radio frequency hub, the module that receives signals from the sensors mounted in each wheel.
According to the NHTSA campaign record for recall 26V559, a software error may prevent the tire pressure monitoring system from detecting low tire pressure, from lighting its warning light, or both. Chrysler reported the problem to the agency on January 9, 2026, according to the same record, well before the public announcement. Reuters, in a report carried by Insurance Journal, said NHTSA announced the recall on September 9. Neither account describes any crash or injury tied to the defect, and the owner letters did not begin mailing until September 17, more than eight months after that report. The risk the agency cites is one of exposure: a driver rolling on an under-inflated tire with no dashboard prompt to check it.
Federal Motor Vehicle Safety Standard 138 and its 20-minute rule
NHTSA states that the affected vehicles do not meet Federal Motor Vehicle Safety Standard 138, the rule that requires a tire-pressure monitoring system on light vehicles. Under the standard as published in the Code of Federal Regulations, the low-pressure telltale must illuminate within 20 minutes of the pressure in one to four tires dropping to a threshold. That threshold is the higher of two values: a pressure 25 percent below the manufacturer’s recommended cold inflation pressure, or a minimum activation pressure in the standard’s table, which is 20 pounds per square inch for standard-load passenger tires.
A second duty matters here too. The same standard requires a malfunction indicator that comes on within 20 minutes of a fault affecting the system’s signals, so a monitor that has stopped working is supposed to say so. A software error that suppresses both the low-pressure lamp and the fault warning is the worst combination, because the driver would have no visible sign that protection is missing.
The design logic behind the rule is simple. Drivers rarely check pressure by hand, and a tire can lose air slowly enough that steering and braking feel normal until heat, a heavy load of passengers and luggage, or a pothole turns a soft tire into a failure. Large three-row SUVs like the Wagoneer family carry more weight on each tire than a compact car does, which makes an unnoticed pressure loss more consequential on exactly the vehicles in this campaign.
Nine model lines across 2024 to 2026
The NHTSA record lists the affected vehicles by model and year. Jeep Grand Cherokee, Grand Cherokee L, Grand Cherokee 4XE and Grand Wagoneer are covered for 2024, 2025 and 2026. Grand Wagoneer L is covered for 2025 and 2026, and the Grand Wagoneer L plug-in hybrid for 2026. The Jeep Wagoneer is included for 2024 and 2025, the Wagoneer L for 2025, and the Jeep Cherokee for 2026. A FOX 13 Seattle report built from the agency notice lists the same families of vehicles.
Counts differ by a single unit between outlets. The agency record and Reuters give 201,976, while an October 2026 recall roundup from Work Truck Online shows 201,975. The federal figure is the one used here, since it comes straight from the campaign filing.
A free dealer update and the owner letters
The remedy costs owners nothing. Dealers will update the radio frequency hub software, and the NHTSA record says owner notification letters began mailing on September 17, 2026. Some press accounts give a later mailing date, but the campaign record itself is the document that fixes the schedule, and it is the one the manufacturer filed with the agency. Owners who want to confirm a vehicle is included do not have to wait for the mail, because VINs became searchable on the agency’s site on September 9.
The simplest check is to enter the 17-character number from the dashboard or door jamb into NHTSA’s recall lookup. Chrysler customer service can be reached at 1-800-853-1403 for questions about scheduling the update, and the recall number to quote is 54D.
Until the software is installed, a lit warning lamp remains useful, but a dark one proves little. A cold-pressure check once a month, using the figure printed on the driver’s door placard, costs a few minutes and does not depend on any module working correctly. Owners of the affected Jeeps would be wise to check tire pressure with a gauge at regular intervals, since the dashboard cannot be trusted to speak up first.
