2026 Ram 1500 Recall: 16K Trucks May Have Faulty Tire Pressure Sensors

Ram is recalling 16,385 model-year 2026 Ram 1500 trucks because faulty tire pressure monitoring system (TPMS) sensors may fail to detect underinflated tires or trigger the warning light as intended.

The recall, filed by Chrysler (FCA US LLC) under NHTSA campaign number 26V623, covers vehicles that may not comply with Federal Motor Vehicle Safety Standard No. 138, which governs tire pressure monitoring systems.

The defect could cause the system to report inaccurate tire pressure. If a tire becomes significantly underinflated without being detected, it could fail and increase the risk of a crash.

Which Ram 1500 Trucks Are Affected?

The recall covers 16,385 trucks built during a production period that began July 1, 2025, and ended March 17, 2026. The period corresponds to a change in the tire and wheel assembly process and ended when that process was updated.

According to FCA US, vehicles outside the recall population were built before or after the suspect period, used tire and wheel assemblies from a different supplier, or had reached a minimum level of maturity.

The automaker estimates that 100% of the recalled vehicles may contain the defect.

Affected vehicle identification numbers (VINs) can be searched on the National Highway Traffic Safety Administration (NHTSA) website.

What Is the Safety Risk?

The tire pressure monitoring system may provide an inaccurate reading, preventing drivers from receiving a reliable warning when a tire is significantly underinflated.

According to the recall report, inaccurate tire pressure indications may result in tire failure, increasing the risk of a crash.

The report states that no warning may occur before the failure. When the malfunction occurs, the TPMS warning light may illuminate.

What Will Ram Do to Fix the Problem?

FCA US will inspect the tire pressure monitoring system sensors and replace them if necessary. The replacement sensors will not have been damaged during the process of mounting the tire on the rim.

The automaker plans to notify dealers on or about October 6, 2026, and begin notifying vehicle owners on or about October 27, 2026.

How the Recall Was Identified

FCA US opened an investigation on March 17, 2026, after identifying inoperative tire pressure monitoring systems in some 2026 Ram 1500 trucks.

Between March and August 2026, the company's Technical Safety and Regulatory Compliance organization worked with engineering and supplier quality teams to examine the issue, identify possible failure modes, and determine which vehicles could be affected.

On September 16, 2026, the organization identified a vehicle build issue that could result in noncompliance with federal safety standards.

On September 22, 2026, FCA US determined through its Vehicle Regulations Committee that certain 2026 Ram 1500 trucks did not comply with Federal Motor Vehicle Safety Standard No. 138.
