Kia Soul Brake Light Failure - Solving The Problem

By Nick Marchenko, PhD

When you're behind the wheel, ensuring that every part of your Kia Soul is in top-notch condition is crucial for your safety. A common issue some drivers may encounter is a brake light failure. This DIY guide will help you diagnose and fix the brake light problem in your Kia Soul.

Tools and Materials Needed

• Replacement bulbs (preferably dual filament if applicable)
• Screwdrivers
• Multimeter

Steps to Diagnose and Fix the Issue

Step 1: Initial Checks

Begin by inspecting the brake light fuse. A blown fuse might be the culprit. If your Kia Soul's top brake light works but the lower ones don't, the fuse is likely intact. However, it's always good to check as a first step.

 Refer to our detailed guide on understanding your Kia Soul's dash warning lights and symbols to interpret any alerts related to electrical issues.

Step 2: Bulb Inspection

Next, check the brake light bulbs. The lower brake lights typically have dual-filament bulbs – one filament for the tail light and another for the brake light function. Replace any bulbs that are faulty.

Step 3: Brake Light Switch

If replacing the bulbs doesn't resolve the issue, the problem might lie with the brake light switch. This switch triggers your brake lights when you press the pedal. If it's malfunctioning, it won't complete the circuit correctly.

Familiarize yourself with common Kia Soul issues and recalls related to the brake system.

Step 4: Electrical Continuity

Using a multimeter, check for continuity in the brake light circuit, including the switch and the socket. Ensure that there is power reaching the brake light sockets when the pedal is depressed.

Step 5: Relay and Ground Check

The brake lights are controlled by a relay. Locate the relay in your fuse box and check for any signs of damage. A bad ground connection could also lead to brake light failure.
