NHTSA Recall 26V559000: Jeep Tire Pressure Monitoring System May Fail to Warn

What the recall covers

Recall 26V559000 (Stellantis reference 54D) covers 201,976 Jeep SUVs whose tire pressure monitoring system may fail to detect low tire pressure or fail to illuminate the TPMS warning telltale. The defective part is not the tire, the valve stem, or the wheel-mounted pressure sensor — it is software inside the Radio Frequency Hub, the module that receives the wireless signal from each wheel sensor. Depending on the failure mode, the module can lose the stored reference pressure values it needs to judge whether a reading is too low, or stop updating pressure values altogether. NHTSA records these vehicles as failing to comply with Federal Motor Vehicle Safety Standard 138, "Tire Pressure Monitoring Systems." Stellantis' filing puts the estimated percentage of vehicles containing the suspect software at 100 percent. The largest groups by far are the 2024–2026 Grand Cherokee (113,647) and Grand Cherokee L (57,456), followed by the 2024–2025 Wagoneer (16,456) and 2025 Wagoneer L (9,749); the 2026 Cherokee and Grand Wagoneer L PHEV each contribute a single vehicle.

The remedy

Jeep dealers will reprogram the Radio Frequency Hub module with corrected software, free of charge. Owner notification letters are scheduled to begin mailing September 29, 2026, in phases running through October 21, 2026. VINs became searchable on NHTSA.gov on September 9, 2026, so owners do not need to wait for a letter. There is no do-not-drive or park-outside advisory for this recall. The remedy is a software reflash, not replacement of the wheel sensors — owners should not buy new TPMS sensors in an attempt to solve a software campaign.

What owners should do now

• Check all four tires by hand with an accurate gauge until the reprogramming is done, and use the cold-inflation pressure printed on the driver-door placard — not the maximum pressure molded into the tire sidewall.
• Do not read a quiet dashboard as proof the system works. The whole point of the recall is that the warning may not appear when a tire is genuinely low.
• Treat dashes instead of pressure readings, a "service tire pressure system" message, or readings that never change as symptoms worth reporting — and say so in those words when you bring the SUV in.
• Because this fix is a dealer reprogramming rather than an over-the-air push, insist on a written repair order recording the visit, the date, and your complaint — not just the campaign number.
• If the TPMS still misbehaves after the reflash, do not assume it is fixed. Document the recurrence and keep the paperwork; a defect that survives a documented repair attempt is what a lemon law claim is built on.
• Get any unexplained repeated pressure loss inspected. A recall about a missing warning does not address a tire that is actually leaking.

How to check your VIN

Confirm whether a specific vehicle is included by entering the 17-digit VIN at nhtsa.gov/recalls or through Mopar's recall lookup. VINs became searchable September 9, 2026. Eligibility turns on build date and installed software, so a matching model and year does not by itself mean a given SUV is covered — and, conversely, a newly filed campaign can take a few days to appear for every VIN.

When this recall can become a California lemon law claim

A recall is not automatically a lemon — it is the manufacturer acknowledging a defect and offering a free fix. Your Jeep may qualify under California's Lemon Law if the recall repair is significantly delayed, doesn't resolve the problem, or your vehicle has other unrepaired warranty defects. In those cases you may be entitled to a buyback, replacement, or cash settlement, with the manufacturer paying your attorney fees. For the full breakdown, see the guides below.
