What Red Warning Lights Mean

Red warning lights are like your car screaming for help. They usually mean something serious is up and you need to act fast. According to Sandyford Motor Centre, red lights mean emergency, while orange or amber lights are more like a polite nudge to get something checked out soon.

Here are some common red warning lights:

• Brake System Warning Light: Something’s wrong with your brakes. Don’t mess around—get it checked immediately.
• EV System Error Light: Your EV’s system is having a meltdown. Time for a quick trip to the mechanic.
• Battery Temperature Warning: Your battery’s getting too hot. Pull over and cool it down before things get worse.

Issues and Solutions

Electric vehicles (EVs) can flash various warning lights on the dashboard, each signaling different issues that need your attention. Knowing what these lights mean is key to keeping your EV in top shape. Let’s break down two common warning lights and what they mean.

Low Battery/Charging Needed

One of the most common warning lights in EVs is the low battery or charging needed indicator. This light pops up when your battery charge dips below a certain level. Ignore it, and you might find yourself stuck on the side of the road.

Why It Happens:

1. Low 12-Volt Battery: In a Nissan Leaf, this light might come on if the 12-volt battery is low or if there’s a problem with the charging system (My Nissan Leaf Forum).
2. High-Voltage Battery Pack Issues: Problems with the high-voltage battery pack can also trigger this warning.

What to Do:

• Charge Up: Plug your car into a charging station ASAP to avoid running out of juice.
• Battery Care: Regularly check your battery’s health and follow best practices like avoiding deep discharges and keeping the battery cool (EG Auto Center).

Limited Power Warning

The limited power warning light is another biggie you shouldn’t ignore. This usually shows up as a red icon with a vehicle and an exclamation mark. It means your car is in reduced power mode to protect the battery or other systems.

Why It Happens:

1. Battery Communication Errors: This can happen if there are errors in the vehicle’s battery systems talking to each other (GMC Canada).
2. Overheating: A red high-temperature sign means overheating, which can lead to dangerous battery levels or engine failure (Sandyford Motor Centre).

What to Do:

• Get It Checked: If this light comes on, get your car serviced to find and fix the issue.
• Reset: Sometimes, resetting the vehicle can clear communication errors.
• Cool Down: If it’s overheating, stop the car and let it cool down. Get professional help if the problem continues.
