Chrysler recalled 201,975 Jeeps because software could silence the tire-pressure warning

Chrysler recalled 201,975 Jeeps — Grand Cherokee, Grand Cherokee L and 4xe, Grand Wagoneer and Wagoneer from model years 2024 to 2026, plus a single 2026 Cherokee — in a filing NHTSA received on September 1, 2026 (campaign 26V559000, FCA number 54D).

The defect is a software error in the radio frequency hub, the module that receives the tire sensors' signals. NHTSA's summary says the tire pressure monitoring system 'may fail to detect low tire pressure,' and the warning lamp may also fail to light. Chrysler acknowledged the vehicles do not meet FMVSS 138, the standard requiring a system that catches significant underinflation and lights a telltale. The failure gives no advance sign — depending on the mode, the cluster may show a service message, a malfunction lamp, or dashes where the placard pressures should be.

The hub is supplied by Valeo North America, according to outlets that read the filing, and similar vehicles outside the suspect build windows had working systems. Pinning the problem down took a year: FCA's compliance team opened an investigation on August 28, 2025, a first root cause surfaced by December 2025, a second in March 2026 widened the scope to 2026 models, a third followed in May, and the noncompliance determination came on August 26, 2026.

The fix is a free dealer software update — no parts. NHTSA's notification says owner letters began mailing September 17, 2026, while the manufacturer's filing describes first-class mail starting about September 29 and phasing through October 21. Until the update is installed, a recalled Jeep's dashboard lamp is not a reliable check on its tires; a manual gauge against the door-jamb placard is.

201,975 SUVs across the 2024–2026 model years recalled; dealers reprogram the radio frequency hub free, no parts needed.

A safety system shipped with software that could stop working without any warning to the driver.

The failure mode is invisible: nothing tells the owner the warning lamp no longer means anything.

It took nearly a year from the first compliance flag (August 28, 2025) to the noncompliance determination (August 26, 2026), leaving the flaw in the field.

One supplier module spread the defect across the entire full-size Jeep line at once.

A safety warning that fails silently is worse than none: owners treat the lamp as their check, so safety-critical software must fail loudly, not quietly.

NHTSA made affected VINs searchable on September 9, 2026, and owner letters began mailing in the second half of September. Dealers reprogram the radio frequency hub at no cost; the repair needs no parts. NHTSA says a driver relying on the failed lamp while a tire loses air faces an increased risk of a crash.
