Jeep Compass Brake Light Switch Guide for 2015-2023 Models
If your brake lights are acting up or you're stuck in park, your brake light switch is the likely culprit.
- A faulty brake light switch can cause brake lights to fail, the vehicle to be stuck in park, or dashboard warning lights to appear.
- The replacement is simple, inexpensive, and can be done by most DIYers in under an hour.
- Verify the correct part for your specific year, as the 2015-2017 (MK) and 2017-2023 (MP) generations may use different switches.
- Driving with a faulty brake light switch is a major safety hazard and should be addressed immediately.
Understanding Brake Light Switch Failure in Your Compass
The brake light switch is a part that wears out over time. Because it's made of plastic and has small electronic contacts, it can fail from repeated use. When it fails, it can cause a range of confusing problems that might not seem related to the brakes at first. For instance, you might get an ABS or traction control warning light on your dash. In some cases, a bad switch can even prevent a push-button start vehicle from starting because the car doesn't get the signal that the brake pedal is pressed. Sometimes, the switch is just out of adjustment and doesn't need to be replaced, which can be checked during diagnosis.
Generation & Part Differences
The Jeep Compass changed significantly in 2017. The 2015-2017 (MK generation) and 2017-2023 (MP generation) can use different brake light switches. Always verify the part fits your exact year before ordering. Using your vehicle's VIN is the best way to ensure you get the correct part.
Choosing the Right Aftermarket Brake Light Switch
When your original switch fails, you have a choice between OEM (Mopar) and several aftermarket brands. Here’s an honest breakdown for your Jeep Compass:
- Mopar: This is the Original Equipment Manufacturer (OEM) part. It's the same one your Jeep came with from the factory. It guarantees perfect fit and function but is usually the most expensive option.
- Crown Automotive: A well-known brand specializing in Jeep replacement parts. They are often considered a high-quality alternative to Mopar and are a popular choice among Jeep owners.
- Standard Ignition (SMP): A large, reputable aftermarket manufacturer. They produce reliable electronic parts, and their switches are a solid, cost-effective choice that often meets or exceeds OEM quality.
- Rostra Powertrain: Rostra focuses on electronic components and is known for quality manufacturing, holding ISO and IATF certifications. They are a trusted supplier for both OE and aftermarket parts.
- Vemo: A German brand that produces a wide range of electronic parts. They market their products as high-quality, meeting stringent standards, and can be a good option if available for your model year.
Pro Tip: OEM vs. Aftermarket
For a simple and inexpensive part like a brake light switch, a quality aftermarket brand like Crown, Standard, or Rostra is often just as reliable as the OEM Mopar part, but at a better price. The key is to buy from a known, reputable brand rather than the cheapest option available, as some very low-cost switches have a high failure rate.

Frequently Asked Questions (FAQ)
Is it safe to drive with a bad brake light switch?
No. If your brake lights are not working, other drivers cannot see when you are slowing down or stopping, which is extremely dangerous. If the switch has failed in a way that keeps the brake lights on, it can confuse other drivers and drain your battery. You should get the vehicle repaired immediately.
Can I replace the brake light switch myself?
Yes, this is a very DIY-friendly repair for most people. The switch is located on the brake pedal bracket under the dashboard. It usually requires no special tools—you just unplug the electrical connector, twist the old switch to unlock it, and install the new one in reverse. The job can be done in under an hour, though the location can be a bit awkward to reach.
Will a bad brake light switch always cause a check engine light?
Not always. A failing switch can cause many symptoms before a warning light appears. However, if the vehicle's computer detects a persistent problem with the signal, it can trigger the check engine light (often with code P0571), ABS light, or traction control light.
My brake lights work, but I can't shift out of park. Could it still be the switch?
Yes. The brake light switch often has multiple electrical contacts inside. It's possible for the contact that controls the brake lights to work while the separate contact for the shift interlock has failed. This is a classic symptom of a failing brake light switch.
