Tesla 'BMS_a067' Battery Charge Level Low — How to Fix

What Does This Error Mean?

Tesla BMS_a067 reads 'Battery charge level low — go to a charger now' (wording varies slightly across firmware).
It triggers when state of charge drops below roughly 5%.
The car will keep driving, but power tapers off as the battery approaches zero.
Drive directly to the nearest charger — let the navigation pick it.
If charge is below ~3%, accept that some features (heating, audio, AC) may shut off to extend range.

Affected Models

Tesla Model 3
Tesla Model Y
Tesla Model S
Tesla Model X

Common Causes

State of charge below 5% — the alert is informational, not a fault
Vampire drain over a long period when parked
Cold weather has lowered usable range below the displayed estimate
Range estimator was optimistic — actual driving used more energy
Hardware issue causing accelerated drain (rare)

How to Fix It

Tap 'Charging' on the navigation.

Tesla's navigation knows where chargers are.
Tap the screen, choose Charging, and pick the nearest Supercharger or Destination charger.
Set the route — the car will adjust climate and power settings to maximise range to that charger.
Reduce climate use.

Heating uses far more battery than cooling.
Drop cabin temp, turn off seat heaters, and turn off the front defroster if conditions allow.
This can buy 10-20 km of extra range when SOC is low.
Drive at 80-90 km/h, not 110.

Aerodynamic drag rises with the square of speed.
Dropping from 110 to 90 km/h saves enough energy to add meaningful range when you're below 5%.
Use the right lane on the highway — let other traffic pass.
Charge to at least 30% before continuing.

When you reach the charger, give it at least 15-20 minutes.
Charging from very low to about 30% is fast (Superchargers deliver peak rate at low SOC).
This restores normal driving behaviour and clears BMS_a067 from the alert list.

When to Call a Professional

BMS_a067 is normal when SOC is genuinely low.
It is only a service issue if it appears with charge above 20% — that suggests a BMS fault and should go to a Tesla service centre.

Frequently Asked Questions

What happens if I keep driving past the alert?

At about 0% the car enters a limp mode that disables HVAC, lowers max power, and gives you a few minutes of crawl to get out of traffic.
Past that the car shuts down and needs a flatbed.
Tesla service strongly recommends not letting it reach 0% — full discharges accelerate battery aging.
