Why Your EV Won’t Charge: Common Charging Faults in Popular Electric Vehicles
By Green’s Garage – Miami’s Trusted EV Repair Shop
Electric vehicles (EVs) are no longer the future—they're the present. Whether you’re cruising in a Porsche Taycan, commuting in a Chevy Volt, or zipping around Miami in a VW e-Golf, EVs are known for their quiet operation, smooth performance, and lower environmental impact. But like any vehicle, they can run into issues—especially when it comes to charging.
At Green’s Garage in Miami, FL, we specialize in diagnosing and repairing EV charging faults. If your car won’t charge, displays a charging fault, or shows an EV propulsion warning, don’t panic—we’re here to help. Let’s take a look at some common charging issues across popular EV models and what they mean.
Chevy Volt: Charging Fault After Plug-In
The Chevy Volt is a plug-in hybrid that has earned a loyal following, but it's not immune to charging issues. One common complaint is the "Service High Voltage Charging System" message that appears shortly after plugging in.
Possible causes:
If your Volt won’t charge or keeps stopping mid-charge, bring it into Green’s Garage. We’ll run diagnostics on your charging system and inspect key components for damage or corrosion.
VW e-Golf: Charging Stops or Fails to Start
The VW e-Golf is fun and efficient—but owners sometimes experience the dreaded charging fault message. This can appear on the dashboard or the VW Car-Net app, typically with no charge initiating at all.
Common issues include:
Incompatible or faulty Level 2 charging station
Software glitches in the charging module
Faulty EVSE (electric vehicle supply equipment)
Before blaming your home charger, let us take a look. We've seen VW e-Golf models that simply need a software update or a quick fix in the charge controller module.
Porsche Taycan: “Charging Fault” or “Reduced Charging Power”
The Porsche Taycan delivers sports car performance with electric power—but some owners report charging faults or reduced charging power messages. This can occur at home or public fast-charging stations.
Likely causes:
Overheating of the onboard charger
Malfunctioning high-voltage battery module
Firmware bugs affecting charge cycles
Connector or pin misalignment in the charge port
Don’t ignore these alerts. A reduced charge rate might be protecting your battery from further damage. Green’s Garage has the tools to read Porsche EV diagnostic codes and service Taycan charging systems safely.
Chevy Bolt: “Propulsion Power is Reduced” or Won’t Charge
The Chevy Bolt is a reliable compact EV, but when things go wrong, you may see a “Propulsion Power is Reduced” warning or find that the car won’t charge at all.
Typical reasons include:
Defective battery module (a known issue in older models)
BMS (battery management system) communication error
Charging cable or inlet fault
Faulty thermal management system
General Motors has issued battery recalls for some Bolt models, and we can check if yours is affected. Even if it’s not under recall, we’ll diagnose whether the issue is with your battery, cooling system, or onboard charger.
Tesla: Car Won’t Charge or "Charging Equipment Problem"
Tesla vehicles are known for innovation, but they aren’t immune to charging faults. You may see a “charging equipment problem” alert on your screen, or the car may simply refuse to start charging.
Root causes may include:
Don’t guess—get it inspected. At Green’s Garage, we handle Tesla charging faults using industry-approved methods, and we know how to troubleshoot both the hardware and software sides of Tesla's charging system.
Don’t Ignore That EV Propulsion Warning
Another frequent issue EV drivers encounter is the “EV Propulsion System Warning.” This often signals a deeper problem that can impact both charging and drivability. It's commonly related to:
High-voltage battery issues
Drive motor control unit faults
Inverter or DC-DC converter problems
These issues can prevent your vehicle from charging properly—or worse, cause it to stop running altogether. If you’re in Miami and get this warning, come see us at Green’s Garage immediately.
