Recall Date: 9/1/2026
NHTSA ID: 26V559
Mfr. Campaign Number: 54D
Manufacturer: Chrysler (FCA US, LLC)
Affected Components: Radio Frequency Hub (RFH) Module
Potential Number of Units Affected: 201,976
Which Jeep vehicles are affected?
The recall reaches nearly every model in Jeep's Wagoneer and Grand Cherokee families:
Grand Cherokee carries the bulk of the population at 113,647 units, followed by Grand Cherokee L at 57,456, Wagoneer L at 9,749, Wagoneer at 16,456, and Grand Wagoneer at 3,046. Grand Cherokee PHEV, Grand Wagoneer L, and two single-vehicle entries for Jeep Cherokee and Grand Wagoneer L PHEV round out the total of 201,976. FCA US lists the estimated percentage with the defect at 100 percent, meaning the suspect software shipped on every vehicle built inside each nameplate's suspect production window.
The problem sits in the Radio Frequency Hub module's software, which can cause the tire pressure monitoring system to lose the reference tire pressures it needs to detect and warn about a significantly under-inflated tire. Federal law requires every vehicle to carry a functioning system that catches low tire pressure and illuminates a warning light, and the RFH software on affected vehicles may not do that reliably, putting the vehicles out of compliance with FMVSS 138.
What drivers need to know
The remedy is a software reprogram of the RFH module, done free of charge at a Jeep dealership. There is no Do Not Drive or Park Outside advisory on this campaign, so owners can keep driving while they wait for their notification. Dealers are expected to be notified on or about September 9, 2026, with owner letters going out in phases from September 29 through October 21, 2026. VINs became searchable at NHTSA.gov/recalls on September 9.
The tricky part for owners is that there is no dashboard warning before the system fails. A driver may see a service message, a warning light, or dashes in place of the normal tire pressure display, but those only appear after the fact, not as an early alert.
Jeep recall background
This campaign took over a year to fully define because the underlying software problem turned out to have three separate root causes, discovered one at a time. FCA US opened its first investigation in August 2025 after engineering testing pointed to a possible FMVSS 138 issue on Grand Cherokee, Wagoneer, and Grand Wagoneer vehicles losing their reference tire pressures. Field data reviewed between December 2025 and March 2026 turned up a second root cause, which is what pushed the scope out to 2026 model year vehicles and added the Jeep Cherokee nameplate. A third root cause, this one preventing tire pressure values from updating at all, surfaced in the following months, and FCA US spent from May through July 2026 finalizing the full vehicle scope before its Vehicle Regulations Committee confirmed the noncompliance on August 26, 2026.
Three distinct causes inside one module is an unusual finding, and it explains why a campaign covering nine separate model and trim combinations took over a year from first investigation to filing. It's also why the fix is entirely software. Whatever combination of causes is present in a given vehicle, a single reprogram addresses all of them.
How BizzyCar can help
A silent defect with no dashboard warning is the hardest kind to sell to an owner who has never noticed a problem, and this campaign spans nine model and trim variants across two of Jeep's highest-volume lineups. BizzyCar's Recall Outreach product identifies every affected VIN in a dealer's own customer base against live NHTSA data and reaches those owners through two-way SMS, explaining the update and booking the appointment without the dealer having to sort nine separate model lists by hand.
A software-only fix also means a short bay time, which makes this exactly the kind of visit dealers can turn into a broader service conversation.
