- Symptoms like being stuck in Park or cruise control failure often point to the brake light switch, not a major transmission problem.
- DIY replacement is simple, located above the brake pedal, and can be done in under 30 minutes.
- Use a high-quality Mopar or premium aftermarket brand, as OEM parts are competitively priced and more reliable.
Understanding Brake Light Switch Failure in Your Cherokee
A failing brake light switch on a 2013-2023 Jeep Cherokee can cause a surprising number of problems. Because this small sensor provides a critical signal to various computer systems, its failure can mimic issues with the transmission, engine, or cruise control. Symptoms can appear suddenly and range from a minor annoyance to a serious safety concern. Before assuming a major repair is needed for a vehicle stuck in Park or with an active warning light, it's wise to check this inexpensive but vital component first.
Common Symptoms of a Bad Brake Light Switch
- Brake Lights Don't Work or Stay On: The most obvious sign is brake lights that either fail to illuminate when you press the pedal or remain lit even when you're not braking.
- Cannot Shift Out of Park: A primary safety feature, the shift interlock, prevents you from shifting out of Park unless the brake pedal is depressed. If the switch fails, the vehicle doesn't get the signal and the shifter remains locked. 🎬 Watch: Troubleshooting a Jeep Cherokee stuck in Park
- Cruise Control Won't Engage: The cruise control system will not activate if it thinks the brakes are being applied. A faulty switch can send a constant 'brake on' signal, disabling the cruise control.
- ABS or ESC Warning Lights: The stability control and anti-lock brake systems rely on the brake switch signal. A bad signal can trigger warning lights on your dashboard.
- Engine Won't Start (Push-Button Start): If you have a push-button start, the system requires you to press the brake before starting the engine. A bad switch prevents the vehicle from knowing the brake is applied.
Recalls and Technical Service Bulletins (TSBs)
As of early 2026, there are no widespread recalls specifically for the brake light switch on the 2013-2023 Jeep Cherokee. An investigation (NHTSA ID: PE22009) was opened for the electronic parking brake module due to water intrusion, which can cause some electrical issues, but this is a separate component. Always check for the latest information using your vehicle's VIN on the NHTSA website.
Choosing the Right Aftermarket Switch
When replacing the brake light switch, you have a choice between OEM and aftermarket parts. For a critical safety component like this, quality matters.
- Mopar (OEM): This is the original part your Jeep was built with. It guarantees perfect fitment and has been tested to meet Chrysler's specifications. Given that OEM pricing is often competitive with premium aftermarket options for this part, it is a highly recommended choice.
- Standard Ignition (SMP): A well-respected aftermarket brand known for producing quality electronic components that often meet or exceed OEM standards. This is a reliable choice if Mopar is unavailable.
- Calorstat: This brand is more commonly associated with thermal and cooling system parts in the European market. While available, it is less common for this specific application in North America compared to other brands.
Pro Tip: Some owners have reported issues with lower-quality aftermarket switches failing prematurely. Given the small price difference, opting for an OEM Mopar or a premium aftermarket brand like Standard Ignition is a wise investment for reliability.

Frequently Asked Questions (FAQ)
Can I replace the brake light switch myself?
Yes, this is a very DIY-friendly repair for most owners. The switch is located above the brake pedal arm and is typically removed by twisting it 90 degrees and unplugging the electrical connector. The job usually takes less than 30 minutes and requires no special tools.
🎬 See this walkthrough for replacing a faulty brake switchHow do I know it's the switch and not a fuse or bulb?
First, check the brake light bulbs. If they are good, check the brake light fuse in the fuse panel. 🎬 Watch: How to find the brake switch fuse and relay If the fuse is also good, but you are experiencing multiple symptoms (e.g., no brake lights AND you can't shift from park), the brake light switch is the most likely culprit.
What are the common trouble 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 (Brake Switch 'A' Circuit Malfunction), P0572 (Circuit Low), and P0573 (Circuit High). These codes strongly indicate a problem within the brake switch circuit.
Do I need to adjust the new switch?
Most modern brake light switches for the Cherokee are self-adjusting. During installation, you typically depress the brake pedal, insert the new switch, and turn it to lock. When you release the pedal, it presses against the switch's plunger, which makes a clicking sound as it automatically sets to the correct depth.
