2021-2022 Tesla Model 3 Braking & Stability Alerts

Symptoms

Owners of certain 2021-2022 Tesla Model 3 vehicles, particularly those equipped with a heat pump, may encounter unexpected warnings. These include "braking and stability control related alerts" that appear on the instrument cluster and touchscreen. These Tesla Model 3 braking alerts typically manifest during the vehicle's power-on sequence.

Root Cause

According to manufacturer communication NHTSA ID 10235000, the underlying cause for these alerts in some Heat Pump Model 3 vehicles is the absence of a hydraulic control unit (HCU) wake-up wire. This omission can lead to temporary communication issues within the vehicle's electronic stability control and braking systems.

What Owners Should Know

If you experience these "braking and stability control related alerts" in your 2021-2022 Tesla Model 3, it's important to know that the issue is often temporary. The manufacturer notes that such faults can typically be corrected and the affected functionality restored by performing a vehicle power cycle. This is a key piece of information for owners encountering the Tesla Model 3 braking alerts.

Owner Action

Should your Tesla Model 3 display braking and stability control warnings, the first recommended step is to perform a vehicle power cycle. This process usually involves powering down the vehicle completely and then restarting it, which can often clear the alerts and restore normal operation. If the issue persists after a power cycle, or if you have any concerns, contact Tesla service for further diagnosis and assistance.

Affected Components

The issue primarily involves the ELECTRONIC STABILITY CONTROL:AUTOMATIC (ASC) system, specifically related to the hydraulic control unit (HCU). While other components like the POWER TRAIN and FUEL SYSTEM, GASOLINE are listed in the general component categories for this communication, the specific fault is tied to the HCU.
