Common EV and Hybrid Warning Lights
Knowing what those lights on your electric or hybrid car’s dashboard mean can save you a lot of headaches. Let’s break down what you need to know about these alerts and their color codes.
Dashboard Alerts: What They Mean
Your electric or hybrid car is packed with dashboard alerts to keep you in the loop about what’s going on under the hood. Here are some of the usual suspects and what they mean:
| Warning Light | Description | Action Required |
|---|---|---|
| General Fault – Something’s seriously wrong. | Get to a garage ASAP. | |
| Limited Power – A yellow tortoise means your car’s slowing down due to electrical issues or battery temperature. | Head to a trusted garage. | |
| Low Battery – A yellow charging station icon with a 2-pin connector and cable. Your battery’s running low. | Charge it up. | |
| Electrical Fault – A car outline with an exclamation mark. Something’s up with the electrical system. | Visit a garage; if it’s red, do it now. |

Color Coding: What Do the Colors Mean?
Those warning lights use colors to tell you how serious the issue is. Here’s the lowdown:
- Green: Everything’s cool. A feature is active or a system is working fine. No action needed.
- Yellow: Heads up! Something needs attention soon. For example, the low battery light kicks in at about 10% charge and starts flashing at 5% (Pod Point).
- Red: Danger, Will Robinson! This is a serious problem that needs immediate action to avoid damage or safety issues. The general fault light is a good example (Pod Point).
| Color | Severity | Example | Action Required |
|---|---|---|---|
| Green | Info | System Active | Chill, no action needed |
| Yellow | Warning | Low Battery | Charge soon |
| Red | Critical | General Fault | Get to a garage now |
Knowing these colors helps you react the right way to keep your car in top shape. For more details on what these lights mean, see our section on EV warning lights meanings.

Troubleshooting and Solutions
Got warning lights on your electric or hybrid car’s dashboard? Let’s break down what’s going on and how to fix it. We’ll cover common issues like low battery, charging system hiccups, and problems with the DC-DC converter and inverter.
Low Battery and Charging System
One of the usual suspects for that pesky EV system warning light is a low 12-volt battery. This little guy powers a lot of your car’s electrical bits. Here’s how to sort it out:
-
Check Battery Voltage: Grab a multimeter and check the battery. A healthy one should read around 12.6 volts. If it’s way lower, you might need to charge or replace it.
-
Inspect Connections: Make sure the battery terminals are clean and tight. Corrosion or loose connections can mess things up.
-
Charge the Battery: If the voltage is low, charge it up. If it won’t hold a charge, time for a new battery.
-
Check for Fault Codes: Use an EV warning lights code reader to scan for any fault codes. This can give you more clues about what’s wrong.
Another reason for the warning light could be a problem with the charging system. This might be due to issues with the onboard charger or the charging equipment. Here’s what to do:
-
Inspect Charging Equipment: Check the charging cable and plug. Look for damage or wear.
-
Check Charging Station: If you’re using a public charging station, try a different one to rule out station issues.
-
Monitor Charging Process: Watch the charging process. If it’s not working right, the onboard charger might be the problem.
-
Consult a Professional: If you’re stuck, get a pro to diagnose and fix the charging system.
DC-DC Converter and Inverter Issues
The EV system warning light can also pop up due to problems with the DC-DC converter or the inverter. These parts are key for managing electrical power in your car. Here’s how to tackle these issues:
-
Check for Fault Codes: Use a hybrid vehicle warning lights scanner to scan for fault codes. This can pinpoint the problem.
-
Inspect Electrical Connections: Make sure all connections to the DC-DC converter and inverter are secure and corrosion-free.
-
Monitor Temperature: Overheating can cause these components to fail. Ensure the cooling systems are working properly. Check for blockages or cooling fan issues.
-
Reset the Vehicle: Sometimes, a simple reset can fix communication errors between battery systems. Follow the manufacturer’s reset instructions.
-
Seek Professional Help: If the problem persists, consult a qualified technician. These components are complex and may need expert attention.
