Meet Matthew Jo: Mechanic, Educator, and EV Advocate
Matthew Jo isn’t just another mechanic—he’s a passionate advocate for electric vehicle technology and education. Through his work at CarTechGa and his extensive YouTube channel (Matthew Jo Official), Matthew has become a trusted voice in the EV community, breaking down complex automotive concepts into digestible, actionable information for vehicle owners.

His YouTube channel has become a treasure trove of information for anyone interested in learning about electric vehicles, featuring detailed explanations of EV systems, maintenance procedures, common issues, and repair processes.
Understanding Electric Vehicle Maintenance
One of the biggest misconceptions about electric vehicles is that they’re maintenance-free. While EVs do require significantly less maintenance than traditional internal combustion engine vehicles—no oil changes, fewer brake replacements due to regenerative braking, and no transmission servicing—they still need regular attention to ensure optimal performance and longevity.
Matthew Jo emphasizes that proper EV maintenance can extend your vehicle’s lifespan, preserve battery health, maintain efficiency, and prevent costly repairs down the road. At CarTechGa, the approach to EV maintenance is comprehensive, addressing both the unique aspects of electric drivetrains and the conventional components that EVs still rely on.
Key EV Maintenance Tasks Recommended by Matthew Jo
Battery Health Monitoring and Management
The battery pack is the heart of any electric vehicle, and Matthew recommends regular battery health assessments using diagnostic equipment that can evaluate cell balance, capacity degradation, and thermal management system performance. At CarTechGa, technicians can identify potential battery issues before they become major problems, helping owners maximize their EV’s range and battery lifespan.
Cooling System Maintenance
Unlike traditional vehicles, EVs often have multiple cooling systems—one for the battery pack, one for the electric motor, and another for the cabin. Matthew stresses the importance of maintaining proper coolant levels and ensuring these systems are functioning correctly, as overheating can significantly impact battery life and vehicle performance.
Brake System Inspection
While regenerative braking reduces wear on physical brake components, Matthew notes that brake pads and rotors still require periodic inspection. In fact, because they’re used less frequently, brake components can sometimes develop corrosion or seize, making regular checks essential.
Tire Rotation and Alignment
EVs are typically heavier than their gas-powered counterparts due to battery weight, and their instant torque delivery can accelerate tire wear. Matthew recommends more frequent tire rotations for EV owners and emphasizes the importance of maintaining proper alignment to preserve range efficiency.
High-Voltage System Inspection
The high-voltage electrical systems in EVs require specialized knowledge and equipment. CarTechGa’s technicians are trained to safely inspect electrical connections, cable insulation, and charging components to prevent electrical issues and ensure safe operation.
12-Volt Battery Service
Many EV owners don’t realize their vehicles still have traditional 12-volt batteries that power accessories and control systems. Matthew points out that these batteries can fail just like in conventional vehicles and should be tested regularly.
Cabin Air Filter Replacement
With EVs’ sealed cabins and reliance on HVAC systems, maintaining clean cabin air filters is crucial for both air quality and system efficiency. Matthew recommends following manufacturer guidelines for replacement intervals.
Software Updates and Diagnostics
Modern EVs are essentially computers on wheels. Matthew emphasizes the importance of keeping vehicle software updated and running comprehensive diagnostics to identify potential issues with the vehicle’s complex electronic systems.
Top 10 Common Electric Vehicle Repairs
Based on his extensive experience at CarTechGa, Matthew Jo has identified the most common repair issues that EV owners face:
1. 12-Volt Battery Failure
Surprisingly, one of the most common issues Matthew sees is 12-volt battery failure. Despite the massive high-voltage battery pack, EVs still depend on a conventional 12-volt battery to power control systems and accessories. When this battery fails, the vehicle won’t start, even with a fully charged main battery.
2. Charging Port and Cable Issues
Repeated plugging and unplugging, along with exposure to the elements, can cause charging port contacts to corrode or become damaged. Matthew frequently repairs or replaces charging ports and diagnoses issues with charging cables that prevent proper connection or slow charging speeds.
3. Brake System Corrosion
Because regenerative braking does most of the work in an EV, traditional brake components are used less frequently. This can lead to rust and corrosion on brake rotors and calipers. Matthew often performs brake cleaning services or component replacement to address this unique EV maintenance challenge.
4. Coolant System Leaks
EV cooling systems are complex, and leaks can develop in coolant lines, pumps, or the battery thermal management system. Matthew emphasizes that coolant leaks require immediate attention, as they can lead to battery overheating and permanent damage.
5. High-Voltage Battery Module Replacement
While complete battery pack failure is rare, individual modules or cells within the pack can fail. CarTechGa has the specialized equipment and expertise to diagnose battery issues and replace faulty modules, often saving owners thousands of dollars compared to full pack replacement.
6. Electric Motor Bearing Issues
Though electric motors have fewer moving parts than combustion engines, bearings can still wear out over time. Matthew can diagnose unusual noises or vibrations and replace worn motor bearings to restore smooth, quiet operation.
7. Onboard Charger Failure
The onboard charger converts AC power from charging stations to DC power for the battery. When this component fails, vehicles may charge slowly or not at all. Matthew has experience diagnosing and replacing faulty onboard chargers across various EV makes and models.
8. HVAC System Repairs
EV heating and cooling systems work harder than in traditional vehicles because there’s no waste engine heat to use for cabin warming. Matthew frequently addresses issues with heat pumps, electric heaters, and AC compressors that can develop problems and significantly impact driving range.
9. Suspension Component Wear
The additional weight of EV battery packs puts extra stress on suspension components. Matthew sees accelerated wear on struts, shocks, control arm bushings, and other suspension parts, requiring more frequent replacement than in conventional vehicles.
10. Software Glitches and Electronic Control Unit Issues
Modern EVs rely heavily on software and electronic control units. Matthew uses advanced diagnostic equipment to identify and resolve software issues, update vehicle programming, and replace malfunctioning control modules that can cause various system failures.
