Tesla BMS_a067 / BMS_a068: Battery Performance Limited
By the EV Fix Guide editorial team · Updated · How we estimate costs
Quick answer
BMS_a067 and BMS_a068 mean the car has found a problem inside the high-voltage battery that limits its performance. Range and charging speed drop, and with BMS_a068 acceleration and top speed are reduced too. The car is OK to drive, but Tesla says service is needed to restore full performance. At a Tesla Service Center this typically costs $0 (Under battery warranty) / $12,000 - $20,000 (Pack replacement, out of warranty). An independent shop charges about $2,500 - $7,000 (Module-level repair, where available) — potential savings of 50% - 80% (out of warranty). Do not attempt this at home.
Symptoms
- 'High voltage battery performance limited - OK to drive - Schedule service soon' alert (BMS_a067)
- 'High voltage battery requires service - Acceleration and charging performance reduced' alert (BMS_a068)
- Lower maximum range and slower charging than before
- With BMS_a068: weaker acceleration and lower top speed
Repair cost: Tesla vs independent shop vs DIY
| Option | Typical cost (USD) |

| Independent shop | $2,500 - $7,000 (Module-level repair, where available) |
| DIY | Not possible at home (High-voltage hazard) |
| Potential savings | 50% - 80% (out of warranty) |

Can an independent shop fix it?
Inside the 8-year battery warranty, this is a Tesla warranty job. Out of warranty, a few independent EV battery labs can diagnose the pack and replace a faulty module or component instead of the whole pack.

Tools a shop uses
- Tesla app and screenshots of the alert
- Purchase date and odometer reading (for warranty)
Steps
- Keep driving normally; Tesla says the car is OK to drive.
- Keep the battery above 30% while the alert is active. Tesla warns the displayed range may not match the real charge level below that.
- Screenshot the alert and note your current maximum range at 100% (or at your usual charge limit) so you can show the change.
- Check warranty coverage: 8 years with a mileage limit that depends on model and year.
- Book service promptly. Tesla warns that without service, range, charging speed and power can keep getting worse.
- Out of warranty, get a diagnosis and quote from an independent EV battery specialist before agreeing to a full pack replacement.
