Is Your Armada's Brake Light Switch Failing?
If you own a 2017-2019 Nissan Armada, you may be familiar with issues related to the brake light switch. Nissan released a Technical Service Bulletin (TSB) #NTB20-065 for this exact problem. The original, solid-black switches were known to fail prematurely, causing a frustrating no-start condition. Even if your Armada is newer, this switch can still wear out and cause problems.
Known Issue: No-Start Condition & BCI Malfunction
A faulty brake light switch is the most common cause of a 2017-2022 Armada not starting when the push-button is pressed. 🎬 Watch: A quick fix for this common no-start condition. The vehicle doesn't recognize that the brake pedal is depressed, which is a requirement for the engine to start. You may also see a "BCI Malfunction" warning light, which can interfere with cruise control and other safety systems.
Symptoms of a Bad Brake Light Switch
- Car Won't Start: The engine doesn't crank, but all the lights on the dashboard work. 🎬 See how to diagnose a no-crank issue that isn't the battery.
- Brake Lights Don't Work: Your brake lights do not illuminate when you press the pedal, a major safety hazard.
- Brake Lights Stay On: The switch can fail in the 'on' position, draining your battery.
- Warning Lights: The ABS or BCI (Backup Collision Intervention) warning lights may appear on your dash.
- Can't Shift Out of Park: The gear selector may be stuck in Park because the system doesn't get the signal from the brake pedal.
- Cruise Control Fails: Your cruise control might not set or could shut off unexpectedly.
Choosing the Right Aftermarket Brake Light Switch
When replacing the brake light switch, you have options ranging from budget-friendly to premium aftermarket. Since the original OEM switch had known issues, a quality aftermarket part can be a reliable and cost-effective solution.
Pro Tip: Nissan updated the original part. The TSB specifies replacing the original solid black switch with an updated version that has a black body and a green connector. When buying an aftermarket part, look for one that is a direct replacement for the updated OEM part number 25320-AX10A.
Aftermarket Brand Tiers
- Premium Aftermarket (Beck Arnley, Standard Ignition, Holstein): These brands are often considered equivalent to, or even better than, the original part. Beck Arnley, for example, is known for sourcing parts from OEM manufacturers for Japanese vehicles. They are a strong choice for reliability.
- Standard Aftermarket (Dorman, True Tech, Facet): These brands offer a balance of quality and price. Dorman is a well-known name that provides a wide range of parts, though quality can sometimes be inconsistent according to some mechanics. They are a good mid-range option.
- Economy (Replacement, URO Parts, Vemo): These brands focus on providing the lowest-cost option. They can be a good choice for a tight budget, but may not have the same long-term durability or precise fit as higher-tier brands.
