2024-2026 Jeep Recall: Tire Pressure Monitor System May Fail/FMVSS 138

The low tire pressure light on 201,975 Jeep Grand Cherokee, Wagoneer, Grand Wagoneer and Cherokee SUVs may stay dark when a tire is low. Software in the radio frequency hub, the module that stores the tire pressure readings, can lose the reference pressures it holds or stop updating the values it reads, and the vehicles do not meet Federal Motor Vehicle Safety Standard 138.

FCA US filed campaign 26V559 with NHTSA on September 1, 2026 for 201,976 vehicles and amended it on September 24 to drop a single 2026 Grand Wagoneer L plug-in hybrid, which left 201,975. FCA's number for the recall is 54D, and its filing puts the share of the population with the condition at 100%.

The Issue

FMVSS 138 requires a tire pressure monitor that detects when one or more tires is significantly under-inflated and lights a low pressure telltale. In these vehicles the system may not accurately detect a low tire or light the telltale.

Between August and December 2025, FCA engineering reviewed the first of three software faults in the hub: the Grand Cherokee, Wagoneer and Grand Wagoneer TPMS losing the reference tire pressures stored in the hub. A second cause of the same loss emerged from field data reviewed with the supplier between December 2025 and March 2026, and it widened the recall to 2026 models and to the Cherokee. The third, found in field data between March and May 2026, prevents tire pressure values from updating, according to the chronology in the Part 573 report.

Both the original filing and the amendment leave the cause field blank. Valeo North America of Troy, Michigan supplied the component, the radio frequency hub module; a supplemental list filed with the report names 66 part numbers for it.

FCA's safety-risk statement is that a system unable to warn the driver of pressures outside recommended limits can cause a crash without prior warning.

Grand Cherokee, Grand Cherokee L and 4xe together account for 171,629 vehicles, about 85% of the recall. NHTSA's record calls the plug-in hybrid the Grand Cherokee 4XE; FCA's filing calls the same 526 vehicles the Grand Cherokee PHEV.

Each production window ends on the day the suspect software left that model's line, except the 2025 Wagoneer L, whose window closes with the last 2025 model built. No date appears for when the condition was corrected in production; that field is blank. For the 2024 model year, FCA says similar vehicles outside the recall had a working TPMS at first sale; for 2025 and 2026, vehicles outside the recall were built after the suspect period.

Chronology and Investigation

FCA's Technical Safety and Regulatory Compliance organization opened an investigation on August 28, 2025, on the basis of engineering testing. At that point the population was 2024-2025 Grand Cherokee, Grand Cherokee L, Grand Cherokee plug-in hybrid, Grand Wagoneer, Grand Wagoneer L, Wagoneer and Wagoneer L.

From May to July 2026 the compliance group and FCA engineering settled the vehicle list, and on July 29 the group recognized a build issue that could amount to a noncompliance. On August 26 the Vehicle Regulations Committee made the determination, and the report reached NHTSA on September 1.

A dealer advance notice went out September 2 saying the remedy was not yet available and the recall was expected to launch in the third quarter of 2026. NHTSA acknowledged the recall on September 8, dealers were to be notified September 9, and the amended report followed on September 24 with the Grand Wagoneer L plug-in hybrid removed from the vehicle list and from the chronology.

Reported Incidents

The Part 573 report gives no count of warranty claims or field reports and mentions no crashes or injuries. Field data appears in the chronology twice, as the source of the second and third root causes, without a number attached.

Remedy and Notification

A dealer reprograms the radio frequency hub with the wiTECH scan tool. The technician compares the module's current part number with the new one, and a vehicle whose module already matches leaves without a flash. No parts are involved, and the filing offers no over-the-air path.

The September dealer bulletin listed the remedy as available for the 2024-2026 Grand Cherokee, Grand Cherokee L and Grand Cherokee plug-in hybrid and for the 2026 Grand Wagoneer and Grand Wagoneer L, and as not available for the 2024-2025 Wagoneer, 2025 Wagoneer L, 2024-2025 Grand Wagoneer, 2025 Grand Wagoneer L and 2026 Cherokee. A revision in October added the 2026 Cherokee and the 2025 Wagoneer, Wagoneer L, Grand Wagoneer and Grand Wagoneer L, which left the 2024 Wagoneer and 2024 Grand Wagoneer still waiting for software.

NHTSA's remedy summary says owner letters were mailed beginning September 17, 2026; the Part 573 report had scheduled a phased mailing from September 29 to October 21. VINs were to become searchable on NHTSA.gov on September 9. Owners can call the Recall Assistance Center at 1-800-853-1403, and the letter points them to recalls.mopar.com and the Mopar Owner's Companion app.

An owner who already paid to have the hub reprogrammed can file at fcarecallreimbursement.com, and the letter says payment follows within 60 days of verified documents.

Symptoms to Watch For

In the filing's words the warning is "none prior to failure," with three exceptions that depend on the failure mode.

A cluster message to service the tire pressure system. It appears on the instrument cluster, and the filing does not give its wording.

A malfunction indicator lamp. The filing abbreviates it MIL and does not say which module sets it.

Dashes in place of the tire pressures. Dashes in place of placard values is the filing's phrase, for the screen that normally shows each tire's reading.

How Long Will the Recall Repair Take?

The owner letter puts the repair at 30 minutes plus check-in and check-out. Dealer labor is 0.3 hour to inspect and update the software and 0.2 hour when the module is already at the current level. The flash needs a battery charger holding 13.2 to 13.5 volts, a charger that can supply 50 to 60 amps on a hybrid, and the vehicle off any high-voltage charger. Only the 2026 Cherokee then needs a drive above 15 mph until the sensors register in the instrument panel.

Bottom Line

Until the hub is reprogrammed, a gauge on each valve stem, read cold against the door-jamb placard, does not pass through the module, and for a 2024 Wagoneer or 2024 Grand Wagoneer that is the routine until FCA releases their software. A dealer must complete 54D on an unsold vehicle before delivery, and the bulletin asks the same of used inventory, so a buyer can ask for the completion record before signing.

FCA's compliance group opened the investigation on August 28, 2025 from engineering testing, and the Part 573 chronology records three separate software root causes in the Valeo radio frequency hub identified between August 2025 and May 2026. Its cause field is blank and it carries no incident counts. On September 24 an amendment removed one 2026 Grand Wagoneer L plug-in hybrid, and the October dealer bulletin still listed no remedy for the 2024 Wagoneer and 2024 Grand Wagoneer.

The 2026 Grand Cherokee, Grand Cherokee L, Grand Wagoneer, Grand Wagoneer L and Cherokee are also in the 844,027-vehicle rearview camera software recall 26V531, filed August 13, 2026. Wagoneer and Grand Wagoneer model years from this campaign also sit in the 97,349-vehicle roof crossbar recall 26V584 filed September 10, and the 2021-2023 Grand Cherokee and Grand Cherokee L are in the rear coil spring recall 26V562, filed September 1, the same day as this campaign.
