Several potential causes could be behind this frustrating situation of the Jeep Compass won’t start but has power, including a brake interlock system, a bad battery issue, or a problem with the ignition system.

Battery Issues

Battery failures are one common reason your Jeep Compass won’t start, and the brake is locked.

Engine starting issues can result from weak or dead battery terminals. Hence, I advise you to inspect the batter connections for cleanliness and security.

If the battery is running low on power, think about jump-starting it or, if required, replacing it. Such problems can be avoided with routine maintenance and occasional battery life inspections.

Faulty Brake System

A malfunctioning brake system also contributes to the problem when the 2018 jeep compass won’t start, and the brake is locked.

  • Brake light switch: If the switch is faulty or misaligned, it may not send the proper signal to the vehicle’s starting system, preventing the engine from starting.
  • Brake pedal position sensor: This sensor may not communicate properly with the dashboard if it fails or sustains damage, which could cause problems if the 2018 Jeep Compass wont start.
  • Brake fluid level: Low brake fluid levels can activate a safety mechanism that locks the brake system to prevent the truck from driving.

Faulty Ignition Switch

The ignition switch is in charge of sending power to various electrical components of the vehicle, including the starter motor, fuel pump, and ignition system.

If the ignition switch is faulty or worn out, it may not provide a lack of power source, leading to the 2019 Jeep Compass won’t start but has power.

The common signs of a malfunctioning ignition switch include trouble turning the key or the key getting stuck in the ignition, intermittent starting problems, or no response when the key is turned to the start position.

Transmission Interlock Issue

The transmission interlock is a safety feature to prevent the vehicle from starting unless the brake pedal is depressed. It ensures that the Jeep is stationary before the engine can be created.

A problem with the transmission interlock system can prevent the brake from releasing and consequence in the starter relay.

In case my Jeep Compass will not start, it can occur due to a faulty interlock solenoid, a malfunctioning brake switch, or issues with the wiring or electrical currents related to the interlock system.

Other Electrical or Mechanical Problems

Electrical problems related to the starter motor, ignition system, worn spark plug, wiring, blown fuses, or relays can make the 2018 Jeep Compass not starting.

On the other hand, mechanical problems can also contribute to a non-starting condition.

These include a malfunctioning fuel pump or filter that disrupts proper fuel supply and delivery.

A faulty crankshaft position sensor or engine control module can also affect the ignition and fuel injection processes, leading to starting difficulties.

What Can I Do To Fix These Problems?

There are some actions I can take to troubleshoot and perhaps fix a Jeep Compass that won’t start with the brake locked:

Check the Battery

Ensure that the battery has sufficient charge. A dead or weak battery can prevent your Jeep from starting. If necessary, jump-start the car or replace the battery.

Verify Brake Engagement

Confirm that the brake pedal is fully engaged. Sometimes, the brake switch may not make proper contact, preventing the vehicle from starting.

Try pressing the brake pedal or reset the brake light firmly while attempting to start the vehicle.

Wiggle the Steering Wheel

Sometimes, the steering wheel can become locked, which can also result in the brake being closed and the vehicle not starting.

In this circumstance, I will gently turn the steering wheel back and forth while simultaneously attempting to start the engine.

Check Transmission Park/Neutral Position

Inspect the transmission to ensure it is in the appropriate park or neutral position. Your car might not start if the gear selector is broken or out of alignment.

While powering up the car, try shifting the gear selector through its various positions.

Inspect Fuse and Relay

Examine the fuse box and relay connections related to the starting system. A blown fuse or faulty relay can disrupt the starting process.

If you find any damaged fuses or relays, change them with new ones of the right rating.

Once these troubleshooting instructions do not resolve the issue, it is recommended to seek the assistance of a qualified mechanic or contact a Jeep service center.

They have the expertise and diagnostic tools to identify and address more complex problems with the brake system, ignition system, check engine light, or other electrical components that may be causing the 2018 Jeep Compass won’t start but has power issues.
