2025-2026 Tesla Model 3 / Model Y TPMS Battery Drain TSB

Tesla has identified an issue with the Tire Pressure Monitoring System (TPMS) in certain 2025 Model 3 and 2026 Model Y vehicles. This concern, detailed in Tesla's TSB referenced by NHTSA ID 11026875, involves an accelerated battery drain in the TPMS sensors, which are critical components of the WHEELS system.

This bulletin provides guidance to technicians on how to address the Tesla Model 3 TPMS drain and Model Y TPMS drain, ensuring proper tire pressure monitoring functionality.

Symptoms

Owners of affected vehicles may notice a warning light or message on their vehicle's display indicating a fault with the tire pressure monitoring system. This could manifest as a general TPMS warning or a specific alert about a low or failing TPMS sensor battery. The primary symptom is the premature failure of the TPMS sensor due to its battery draining faster than expected.

Diagnosis

When a vehicle presents with symptoms of a TPMS fault, technicians will perform diagnostics to pinpoint the exact cause. For the issue described in TSB 11026875, the diagnostic process involves identifying which specific TPMS sensor is experiencing accelerated battery drain. This typically requires specialized diagnostic tools to read the status of each sensor.

Repair Procedure Summary

Once the affected TPMS sensor is identified, the repair procedure involves replacing the faulty sensor. This process ensures that the tire pressure monitoring system can accurately report tire pressures and maintain its intended safety function. The replacement of the sensor is a straightforward process for trained Tesla technicians.

Owner Action

If you own a 2025 Tesla Model 3 or a 2026 Tesla Model Y and suspect an accelerated Tesla Model 3 TPMS drain or Model Y TPMS drain, you should schedule a service appointment with a Tesla service center. Inform them of any TPMS warning lights or messages you have observed. The service center will be able to diagnose the issue and perform the necessary replacement of the affected TPMS sensor under the guidelines of TSB 11026875.
