High-Voltage Expertise Beyond the Dealership

Electric and hybrid vehicles operate on 400V+ systems that are dangerous for untrained mechanics. MGI Auto technicians hold specific High-Voltage Safety certifications to diagnose battery packs, inverters, and electric motors safely and accurately.

High-Voltage Battery Health Analysis

The battery is the most expensive part of your car. We perform deep-dive scans to check the “State of Health” (SOH) of individual battery cells. Often, a failing battery is caused by a few bad cells or corroded busbars, not the entire pack. We identify the specific issue before recommending a solution.

Inverter & Converter Cooling Systems

Heat is the enemy of electronics. Your EV has dedicated cooling loops for the inverter and battery that are separate from the engine. We service these electric water pumps and flush the specialized non-conductive coolant to prevent overheating that can fry your power electronics.

Charging Port & Cable Repair

If your car refuses to charge or the plug feels loose, the onboard charging module or the physical port may be damaged. We troubleshoot charging failures (Level 1, 2, and DC Fast Charging) to distinguish between a grid issue, a cable fault, or an internal vehicle component failure.

Warning Signs of Hybrid/EV System Failure

  • Red Triangle: The "Red Triangle of Death" or High Voltage warning light is on.
  • Range Drop: The vehicle is losing range significantly faster than normal.
  • Loud Hum: Excessive fan noise from the rear seat (battery cooling fan) or under the hood.
  • Charging Error: The car plugs in but stops charging after a few minutes.
  • Jerky Acceleration: The transition between electric motor and gas engine feels rough.

Certified EV & Hybrid Repair FAQ's

Do I have to take my EV to the dealership to keep the warranty?

No. In Canada, you have the right to service your vehicle at any certified shop without voiding the manufacturer’s warranty. MGI Auto follows all factory service intervals and documents the work to ensure your warranty remains valid.

Less fluids, more checks. While you don’t need oil changes (for BEVs), you still need cabin filters, brake fluid, and coolant flushes. Crucially, the suspension and tires on EVs wear out faster due to the heavy weight of the battery, requiring more frequent inspection.
Often, yes. A hybrid battery failure is often just degradation of the copper connectors or a clogged cooling fan filter. We inspect these serviceable components first. Cleaning the cooling fan and busbars can sometimes restore function without needing a $4,000 battery replacement.
Yes. We perform suspension repair, brake service, alignment, and cabin filter replacements for Tesla Model 3, Y, S, and X. We also diagnose non-warranty electrical issues, offering a faster alternative to the Tesla Service Center for mechanical repairs.

Detailed process. A proper battery analysis involves charging and discharging the battery while monitoring the voltage of every cell block. This diagnostic service typically takes between 2 to 4 hours to gather accurate data on the battery’s true capacity.

Why Choose MGI Auto?

Safety and precision are non-negotiable when working with high voltage. MGI Auto utilizes Class 0 insulated tools and certified safety protocols to protect both the technician and the vehicle’s sensitive electronics. Diagnostic access to OEM-level software allows for proper reading of battery cell voltages and module temperatures, ensuring that repairs address the root cause rather than simply swapping expensive components.
