Chrysler's FCA US unit is recalling 16,385 model year 2026 Ram 1500 pickups in the United States because the tire pressure monitoring system sensors may not detect low pressure, or may fail to turn on the warning light. NHTSA lists the recall as campaign 26V623. The company's recall number is 51D.
FCA reported the problem to NHTSA on September 29, 2026. The agency says the trucks fail to meet Federal Motor Vehicle Safety Standard 138, which governs tire pressure monitoring systems, and that a warning light that does not alert the driver to low pressure increases the risk of a crash.
What the recall covers
Only 2026 Ram 1500 trucks are included. NHTSA's record does not name trims, cab styles or a build-date range, and it does not say how many sensors have failed in service or whether any crashes or injuries have been reported. The recall is for the sensors themselves, so a truck can look and drive normally while its warning system is blind.

Why a quiet sensor matters
A tire pressure warning is the only alert most drivers get before a slow leak turns into a flat, a blowout or a tire that overheats under a load. Pickups are driven heavy more often than most vehicles, with cargo in the bed, a trailer on the hitch or a full crew cab, and that is when low pressure does the most harm to handling and braking distance.
A sensor that never lights the warning is worse than one that lights it for no reason, because the driver has no sign anything is wrong. For now, the practical defense is old-fashioned. Check all four tires and the spare with a gauge at least monthly, and before any long trip or tow, using the pressures on the door-jamb placard.
Separately, Ram is recalling 265,512 ProMaster vans over a power-steering problem under campaign 26V621. That one is a different model and a different defect.
What 1500 owners should do
Look up your VIN at nhtsa.gov/recalls. NHTSA says the affected VINs became searchable on October 6, 2026. Owner notification letters are expected to be mailed October 27, and the fix is not an over-the-air update, so it requires a dealer visit. Dealers will inspect the sensors and replace them as necessary at no charge.
FCA US customer service can be reached at 1-800-853-1403; cite recall number 51D. If your TPMS light has come on and off unexpectedly, or has never lit at all on a tire you know is low, tell the service advisor so it is recorded with the repair.
