2019 Jeep Compass Start Stop Not Working

The 2019 jeep compass start stop feature may not work properly due to a malfunctioning battery. This issue can be resolved by getting the battery checked and replaced if necessary.

The start stop feature in your 2019 jeep compass might not function as expected due to a faulty battery. One of the primary reasons behind the issue is a low charge, which can cause the battery to die, and the start stop feature won’t work.

It is essential to have the battery’s condition inspected by a professional to determine whether it needs to be replaced or not. A competent technician can assist you in determining the cause of the problem and offering appropriate advice. In this guide, we’ll go over some reasons why the start stop feature in your jeep compass may not be functioning correctly and what you can do to troubleshoot it.

Battery And Charging Issues

Battery Aging

One of the primary reasons for the start-stop feature failure is battery aging. As the battery gets old, its ability to store the charge decreases, and eventually, it will not have enough power to start the engine.

  • Slow engine crank when starting,
  • Dim headlights,
  • Vehicle taking longer to start after every stop.

To prevent the battery from aging too quickly, you should:

  • Avoid leaving electronic devices running when the engine is off.
  • Switch off the lights when not in use.
  • Make sure that the battery terminals are clean and tight.

Battery Size And Capacity

The size and capacity of the battery also affect the start-stop feature. A battery with a smaller size and capacity means that it will require more power to start the engine, decreasing its overall lifespan.

To ensure that your battery size and capacity are optimal, you should:

  • Get the right type of battery for your vehicle.
  • Opt for a higher cold-cranking amp (cca) battery.
  • Make sure that the battery is appropriately charged.

Problems With The Alternator

The alternator converts mechanical energy into electrical energy, which is used to power the vehicle. If the alternator is faulty, the battery will not charge correctly, leading to the failure of the start-stop feature.

Some of the signs of a problematic alternator include:

  • Dimming lights while driving,
  • The battery sign appearing on the dashboard,
  • Strange noises coming from the engine.

To avoid problems with the alternator, it’s essential to:

  • Have it checked routinely.
  • Replace it if it’s faulty.

Faulty Electrical Connections

Faulty electrical connections can cause various electrical malfunctions in the vehicle, including the start-stop feature. Loose, corroded, or damaged electrical connectors can cause a power shortage leading to the failure of the system.

To avoid a faulty electrical connection, you should:

  • Inspect the connections regularly,
  • Tighten loose wires,
  • Clean corroded connections.

Battery and charging problems can cause the 2019 jeep compass start-stop feature to fail. Regular maintenance and inspection of the battery, alternator, and electrical connections can prevent these problems and ensure the longevity of your jeep’s start-stop feature.

Sensor And Actuator Issues

If you have a 2019 jeep compass, and you’re facing issues with the start-stop system, the culprit could be a fault in the sensor and actuator system. This system contains various parts that work together to ensure a smooth functioning of the vehicle. A malfunction in any of these parts may lead to an issue with the start-stop system.

Failure Of Engine Control Module

The engine control module (ecm) is responsible for managing critical engine functions and monitoring the start-stop system. A malfunction in the ecm may lead to the start-stop system not working optimally. Symptoms of this issue include the engine turning off and not starting when you press the accelerator.

Malfunctioning Of The Brake Pedal Switch

The brake pedal switch is a crucial component that sends a signal to the ecm, indicating that the vehicle has come to a stop. If the brake pedal switch is malfunctioning, the ecm may not register that the vehicle has come to a stop, and the start-stop system may not work.

Damaged Starter

Another possible reason for the start-stop system failing to work could be a damaged starter. A damaged starter will not be able to provide sufficient power to the engine, and the engine will not start. The start-stop system will not work if the engine does not start.

Issues With The Environmental Conditions Sensor

The environmental conditions sensor is responsible for detecting the environmental conditions, including temperature and humidity. If this sensor is faulty, the system may not be able to determine if it is safe to shut off the engine. It may cause the system to turn off the engine even when it’s not safe to do so.

The start-stop system in your 2019 jeep compass may not work due to issues with the sensor and actuator system. The possible components that may cause this issue include the engine control module, brake pedal switch, damaged starter, and environmental conditions sensor.

If you notice any of the symptoms mentioned above, it is essential to take your vehicle to a professional mechanic for an evaluation.

Software And Configuration Issues

Are you the owner of a 2019 jeep compass and facing issues with the start-stop feature? You are not alone. The start-stop feature is a relatively new technology that shuts down the engine when your vehicle comes to a halt, restarting it when you hit the accelerator.

The feature helps to conserve fuel and reduce emissions. However, the complexities involved in this technological feature means that software and configuration issues arise frequently. Let’s delve into different types of software and configuration issues that can cause problems with the 2019 jeep compass start-stop feature.

Problems With The Firmware Updates

Sometimes, firmware updates can cause more problems than any good they were designed for. This is the case with the 2019 jeep compass, where firmware updates have been known to cause the start-stop feature to malfunction. Firmware updates that are installed incorrectly, or not installed at all, could cause issues with the start-stop feature functionality. Such problems with firmware can only be resolved by a qualified technician.

Malfunctioning Of The Control Unit

In some instances, the problem lies with the control unit responsible for the start-stop feature. This is a complex part of your jeep compass, and any malfunctioning could cause the start-stop feature not to work. If the control unit has failed, it needs to be replaced with an original one to address the issue.

Improper Configuration Of The System

Another common issue that affects the start-stop feature is an improper system configuration. This happens when someone misconfigures the software responsible for the start-stop feature, leading to unexpected behavior and a malfunction of the feature. A qualified technician must correctly configure the system to ensure the configuration is optimal for your jeep compass.

Issues With The Engine Performance

Engine performance can also impact the start-stop feature. Any issue with the engine’s performance, such as increased engine vibration, engine stalling, or slow engine start-up, can make the start-stop feature not work as expected. If you experience such engine performance issues, ensure you take your jeep compass to a qualified mechanic for inspection and maintenance.

Software and configuration issues are the most common culprits behind a malfunctioning start-stop feature in the 2019 jeep compass. The four significant types of problems reviewed in this article include problems with firmware updates, malfunctioning of the control unit, improper configuration of the system, and issues with engine performance.

If you’re experiencing any of these issues with your start-stop feature, always consult an expert for proper diagnosis and repair.

Common User Mistakes : Why Your Start-Stop System May Not Be Working

The start-stop system in the 2019 jeep compass is designed to save fuel and reduce emissions when your vehicle is idling. However, if you’re experiencing issues where the start-stop system seems to be malfunctioning, there are several common user mistakes that could be the culprit.
