Understanding a Common Point of Failure
The brake light switch in the 2012-2016 Dodge Dart is a mechanical part with a finite lifespan. Because it's used every time you brake, its internal contacts and plastic components can wear out. Given its multiple roles in the vehicle's electronic systems, a failing switch can cause a range of confusing symptoms that may not seem related to the brake lights at first. Fortunately, it's an inexpensive part and is relatively simple to replace.
Symptoms of a Failing Brake Light Switch
When this switch starts to fail, your Dart will give you clear signs. You might notice one or more of the following issues:
- Brake Lights Don't Work: The most obvious and dangerous symptom. Your brake lights may fail to illuminate when you press the pedal.
- Brake Lights Stuck On: The switch might fail in the 'on' position, keeping your brake lights illuminated constantly and draining your battery.
- Cruise Control Inoperable: If the switch is faulty, the car's computer may think the brakes are applied, preventing you from setting the cruise control.
- Can't Shift Out of Park: The safety interlock requires a signal from the brake switch to release the shifter. A bad switch can leave you stranded.
- ABS or Traction Control Lights: A faulty brake switch can send erratic signals to the Powertrain Control Module (PCM), sometimes triggering warning lights on your dash.
Recalls and Technical Service Bulletins (TSBs)
As of early 2026, there are no active NHTSA recalls or widespread Technical Service Bulletins specifically for the original equipment (OEM) brake light switch on the 2012-2016 Dodge Dart. While other recalls exist for the Dart, they do not pertain to this specific component. Always check for the latest information using your vehicle's VIN on the NHTSA website.
Choosing the Right Aftermarket Part
For a simple component like a brake light switch, aftermarket parts offer excellent value without a significant compromise in quality compared to OEM. The key is to choose a reputable brand.
- Standard Ignition (Standard): This is a well-known and trusted aftermarket brand. They are a common choice in professional repair shops and often have reviews indicating good fit and function. They are a reliable replacement for the original part.
- Calorstat by Vernet: Calorstat is a large manufacturer of various automotive sensors and components. While not as commonly discussed in North American forums as Standard, they are an established OEM supplier in Europe and produce parts that meet rigorous specifications.
Pro Tip: Both Standard Ignition and Calorstat are solid choices for a replacement switch. Since the labor is the same regardless of the brand, and the price difference is minimal, either brand will effectively solve the issue. The decision can simply come down to availability or your personal preference.

Frequently Asked Questions
Is this a difficult part to replace myself?
No, it is not technically difficult, but it can be physically awkward. The switch is located up under the dashboard by the brake pedal, requiring you to work in a tight space. The process involves a simple twist-and-pull motion to remove the old switch and disconnect a wiring clip. No special tools are required, making it a very feasible DIY job for most people.
My cruise control doesn't work. Could it really be the brake light switch?
Yes, absolutely. The cruise control system needs to know when you press the brake pedal so it can disengage. If the brake light switch is faulty and sending a constant 'brakes applied' signal to the computer, the cruise control will not be allowed to activate. It is one of the most common causes for cruise control failure.
The new switch looks slightly different. Is that okay?
Minor cosmetic differences between the OEM and aftermarket switch are common and usually not a cause for concern. The critical aspects are the electrical connector and the mounting tabs. As long as it plugs in correctly and locks securely into the bracket, it should function properly. These switches are designed to be self-adjusting upon installation.
What are the error codes for a bad brake light switch?
A failing brake light switch can trigger several Diagnostic Trouble Codes (DTCs). The most common ones are P0571 (Cruise Control/Brake Switch A Circuit Malfunction), P0572 (Brake Switch 'A' Circuit Low), and P0573 (Brake Switch 'A' Circuit High). If you have a check engine light on, scanning for these codes can help confirm the diagnosis.
