Dodge Journey Brake Light Fail - Common Causes And Solutions

By Nick Marchenko, PhD

If you're a Dodge Journey owner experiencing brake light issues, you're not alone. This guide combines insights from various Dodge Journey owners who have faced similar problems, offering a comprehensive DIY approach to fixing your brake light. Remember, while this guide is helpful, always consult a professional if you're uncertain.

Step 1: Diagnosing the Problem

• Initial Check: Start by checking if the LED brake light assembly is the issue. Unlike traditional bulbs, these assemblies require a complete replacement when faulty.
• Further Inspection: Check other functions of the light assembly, like the turn signal and backup light. If these work, your problem might be isolated to the LED brake light.

If your LED brake light assembly keeps failing, consider replacing it with traditional bulbs. Find out what bulbs are used in brake light position of your Dodge Journey here:

Step 2: Replacement and Testing

• If the LED assembly seems faulty, consider purchasing a replacement, possibly from a site like eBay.
• After replacement, if the issue persists, it's likely not the assembly but something else – possibly wiring or a fuse.

Step 3: Investigating Wiring Issues

• A common problem in Dodge Journeys is broken wires in the flexible wire harness at the top of the hatch. The frequent opening and closing of the hatch can lead to this issue.
• Inspect the wiring, especially around grommets and sharp metal edges. Damaged or crimped wires can cause the light to fail.
• Soldering broken wires back together can be a DIY fix for wiring issues.

Step 4: Checking the Fuse Box

• Consult the owner's manual to identify the right fuses associated with the exterior lights.
• The Journey's fuse box might have fuses labeled "Exterior Lights 1" and "Exterior Lights 2," which you should check and replace if necessary.

Step 5: Understanding Additional Factors

• If your Journey has a trailer light converter (especially in models with aftermarket hitch installations), this could be the root cause. A malfunctioning converter can disrupt the brake light functionality.
• The problem could also be related to the thin wiring outside the thick rubber grommet, which is part of the trailer light setup.

Step 6: Final Testing and Troubleshooting

• After addressing potential wiring and fuse issues, test the brake light again.
• If the light still doesn't work, consider using a voltmeter to check for electrical continuity and voltage discrepancies between the working and non-working sides.
• It's also worth checking if there's an inline fuse near the battery, particularly if a trailer hitch was installed.

Step 7: When to Seek Professional Help

If the brake light issue persists despite your troubleshooting, it's time to consult a professional mechanic. Sometimes, the complexity of electrical systems in vehicles like the Dodge Journey requires expert intervention.

Preventative Measures and Maintenance Tips

• Regularly inspect the wiring harness, especially if you frequently use the hatch.
• Consider replacing bulbs and checking for corrosion in terminals as part of routine maintenance.
• Keep an eye on the dashboard for any indication of electrical issues.

By following these steps, you can address the common brake light issues found in Dodge Journeys. Remember, electrical systems can be intricate, so proceed with caution and consult professionals when in doubt.
