Advanced EV Care: Tesla High Voltage Battery Repair & Rebuild in Houston, Sugar Land & Katy

When your electric vehicle experiences range degradation, charging failures, or the dreaded “Maximum battery charge level reduced” alert, you don’t have to face a staggering dealership replacement bill. At Texas International Motors, we provide cutting-edge Tesla service and repair in Houston, Sugar Land, and Katy, Texas, specializing in component-level diagnostics and advanced Tesla high voltage battery rebuilds.

Our facility offers a sophisticated, cost-effective alternative to complete battery pack replacement, saving local EV owners thousands of dollars while restoring factory-spec performance.

Component-Level Tesla HV Battery Rebuild & Repair

The standard dealership solution for a failing battery pack is to completely swap it out, often costing upwards of $15,000 to $20,000. As an advanced independent Tesla specialist, we dive deeper. Tesla battery packs consist of multiple interconnected modules and hundreds of individual lithium-ion cells. Frequently, a pack failure or sudden drop in range is caused by just one failing cell group or a faulty monitoring component.

Our specialized electric vehicle technicians safely isolate, drop, and service your high voltage system, offering precise solutions including:

• Tesla Battery Cell Module Replacement: We locate and replace specific degraded modules within the pack, re-balancing the voltage across the entire system to restore your original driving range.

• BMS (Battery Management System) Repair: Diagnosing and fixing internal circuit board faults, sensor errors, and communication glitches that trigger false battery failure alerts.

• Contactor & Pyrofuse Replacement: Replacing worn high-voltage contactors and blown pyrofuse safety switches to restore power delivery to the drive units.

• Cooling System & Isolation Fault Fixes: Repairing internal coolant leaks and resolving critical “Isolation Fault” codes caused by moisture or internal pack degradation.
